Summary

ughes Space and Communications International, Inc. (Hughes) attempted
to launch two communications satellites from the PRC on Long
March rockets which exploded before reaching orbit, one in
1992 and one in 1995. Allegations regarding technology transfer
arose in connection with failure analysis investigations conducted
by Hughes employees in the aftermath of these failed launches.
Specifically, in 1992 and 1995, China Great Wall Industry Corporation,
a PRC government entity, launched two Hughes satellites manufactured
for Australian (Optus B2) and Asian (Apstar 2) customers from
a PRC launch facility in Xichang, PRC.
Both satellites were launched on a Long March 2E rocket.
In both cases, an explosion occurred after take-off and before
separation of the satellite. Hughes investigated the causes of
both of these failed launches and determined that the rocket
was the cause of the failures.
In the course of the investigations, Hughes communicated
technical information regarding the rocket to the PRC that assisted
the PRC in improving the Long March 2E rocket. The activities
of Hughes employees in connection with the investigation of the
failed launch in 1992 resulted in the transmission to the PRC
of technical information that appears to have been approved by
a U.S. Government representative but not properly licensed. In
the case of the 1995 Hughes failure investigation, Hughes employees
exported technical information that also was approved by a U.S.
Government representative but should not have been authorized
for export to the PRC.
In both cases, Hughes disclosed information to the PRC
that related to improving the Long March 2E fairing, a portion
of the rocket that protects the payload during launch. Such
information was outside the scope of the original licenses Hughes
obtained from the State and Commerce Departments, respectively,
with respect to the export and launch of the Optus B2 and Apstar
2 satellites. Hughes claims that the 1993 Optus B2 failure analysis
disclosures were cleared in advance by U.S. Government officials,
but neither Hughes nor the pertinent U.S. Government agencies
retained records that would substantiate this claim fully.
The lessons learned by the PRC from Hughes during the 1995
Apstar 2 failure investigation are directly applicable to fairings
on other rockets, including those used to launch PRC military
satellites.
Although the Long March 2E has not been used since 1995,
it is possible that the PRC may have transferred the lessons
learned from this launch failure investigation to its ballistic
missile programs. These lessons could lead to the development
of a more reliable fairing for use with advanced payloads on
military ballistic missiles.
Hughes obtained a clearance for the 1995 disclosures that
was improperly issued by a Commerce Department official.
Hughes was confident that the cause of the 1992 launch failure
on the PRC's Long March 2E rocket was the fairing. Hughes then
ascertained with more certainty that the fairing was responsible
for the 1995 launch failure. Hughes required that the PRC take
appropriate corrective measures so that future launches of Hughes
satellites on the Long March 2E rocket could occur and be insured.
Hughes employees conveyed to the PRC the engineering and
design information necessary to identify and remedy the structural
deficiencies of the fairing. At the time of the 1992 failure,
the export of both the satellite and any information that might
improve the rocket were subject to State Department licensing
jurisdiction.
Hughes knew that the fairing was part of the rocket and
that a State Department license was required to discuss improvements
with the PRC. Although Hughes did not have a license to disclose
information to the PRC relating to improvement of the fairing,
Hughes, nonetheless, made such disclosures. Hughes claims that
each disclosure was authorized by the Defense Technology Security
Administration monitor. Contemporaneous Hughes records partially
support this assertion. The monitor says he doubts that he in
fact approved the disclosure, but says he cannot fully recall
these matters.
Neither Hughes nor any relevant U.S. Government agency
has been able to produce records substantiating all of the claimed
approvals. Even if such approvals were in fact given, they
would have exceeded the authority of the Defense Technology Security
Administration monitor since he was not empowered to expand the
scope of the license granted by the State Department. The monitor
also should have known that a separate license was needed for
the launch failure analysis activities. By the time of the 1995
failure investigation, partial jurisdiction for commercial satellites
had been transferred to the Commerce Department, but licensing
for improvements to any part of the rocket, such as the fairing,
remained with the State Department.
Hughes officials who were responsible for the launch failure
investigation in 1995 knew that technical information that would
improve the rocket, including the fairing, was still subject
to State Department jurisdiction and was not licensed for export.
Nonetheless, Hughes sought Commerce Department approval to disclose
information regarding the fairing to the PRC. A Commerce Department
official, without consulting with Defense Department or State
Department experts, approved that disclosure, he says, on the
assumption that the fairing was part of the satellite, not the
rocket. He now acknowledges that this decision was a mistake.
The Defense Department recently determined that the information
Hughes made available to the PRC was sufficiently specific to
inform the PRC of the kinds of rocket changes and operational
changes that would make the Long March 2E, and perhaps other
rockets, more reliable. In particular, Hughes assisted the
PRC in correcting the deficiencies in its models of the stresses
or loads (such as buffeting and wind shear) that the rocket and
payload experience during flight.
There are differing views within the U.S. Government as
to the extent to which the information that Hughes imparted to
the PRC may assist the PRC in its ballistic missile development.
There is agreement that any such improvement would pertain to
reliability and not to range or accuracy. It is not clear, at
present, whether the PRC will use a fairing that was improved
as a result of Hughes' disclosures in a current or future ballistic
missile program. Currently-deployed PRC ballistic missiles do
not use fairings, and the PRC's future mobile land-based intercontinental
ballistic missiles will probably not use a fairing. However,
fairings are used by the PRC in launching military communications
satellites and could be used for a submarine-launched ballistic
missile.
In the opinion of the Select Committee's independent expert,
Dr. Alexander Flax, fairing improvements could also be of benefit
to multiple independently-targeted reentry vehicle (MIRV) development,
should the PRC decide to move in that direction. (See the Technical
Afterword at the end of this chapter for additional details on
the possible uses of fairings in intercontinental ballistic missiles.)
Hughes also provided the PRC with practical insight into
diagnostic and failure analysis techniques for identifying and
isolating the cause of a launch failure. Whether or not the
structural improvements to the fairing suggested by Hughes are
of immediate use to the PRC's missile programs, that information
expanded the PRC's repertoire of available technical solutions
to future problems that it may encounter in its space and missile
programs.
Finally, the Select Committee's independent expert has
concluded that Hughes provided the PRC with the benefit of its
engineering experience and know-how. As a result, PRC engineers
better understand how to conduct a failure analysis and how to
design and build more reliable fairings for rockets: "This
will stand them in good stead in developing fairings (or shrouds)
for ballistic missiles."

OPTUS B2,
APSTAR 2 LAUNCH FAILURES
PRC GAINS SENSITIVE
KNOWLEDGE FROM
HUGHES INVESTIGATIONS

n 1992 and 1995, two Hughes Space and Communications International,
Inc. (Hughes) satellites were launched from the People's Republic
of China on Long March 2E rockets and failed to achieve orbit.
It has been alleged that, in the failure investigations that
followed, Hughes provided technical information to the PRC that
assisted the PRC in improving the Long March 2E. This portion
of the report examines the events that underlie those allegations.
The 1992 failure involved the Optus B2 satellite, while the
Apstar 2 satellite was destroyed in 1995.
For each event, provided below is a brief discussion of the
export licenses for the satellite, and the restrictions that
the licenses contained.1 A short discussion of the actual events
of the failed launches follows, along with a detailed review
of the failure investigations that Hughes conducted and of the
U.S. Government's actions that related to those investigations.
Hughes' efforts during the investigations to provide technical
information to the PRC for the purpose of assuring success in
future launches are explained, as is the extent of the U.S. Government's
knowledge and approval of Hughes' actions.
Finally, the actual improvements that were made to the Long
March 2E by the PRC, and assessments of the potential damage
to national security resulting from those improvements, are discussed.
The Prohibition Against Technology
Transfer
In Foreign Launches

International
Traffic in Arms Regulations
and the U.S. Munitions List
Section 38 of the Arms Export Control Act2 (AECA) authorizes
the President to control the export and import of defense articles
and services. The International Traffic in Arms Regulations (April
1, 1992 edition) contain the following definitions of defense
articles and defense services:3
Section 120.7 Defense article.
Defense article means any item designated in Section 121.1.
This term includes models, mockups, and other such items which
reveal technical data directly relating to items designated in
section 121.1
Section 120.9 Defense service.
Defense service means:
(a) The furnishing of assistance (including training) to foreign
persons whether in the United States or abroad in the design,
engineering, development, production, processing, manufacture,
use, operation, overhaul, repair, maintenance, modification or
reconstruction of defense articles, whether in the United States
or abroad...
The U.S. Munitions List also enumerates articles that are
controlled under the authority of the AECA in relevant part as
follows:
Section 121.1 General. The United States Munitions List
(a) The following articles, services and related technical
data are designated as defense articles and services.
Category IV Launch Vehicles [rockets].
(b) Launch vehicles and missile and anti-missile systems
including but not limited to guided, tactical and strategic missiles,
launchers, and systems.
(h) All specifically designed or modified components, parts,
accessories, attachments and associated equipment for the articles
in this category.
Department
of Defense Monitoring Role
U.S. Air Force Instruction 10-1210, "Technology Safeguard
Monitoring for Foreign Launches of US Commercial Satellites,"
identifies the Defense Technology Security Administration4 as
having responsibility for the objectives of the technology safeguard
program, which include:
to support the US non-proliferation policy for space
and missile technology, . . . the International Traffic in
Arms Regulations, and the US Munitions List.5
Defense Technology Security Administration monitors are responsible
for "controlling the disclosure of technical information."6
The U.S. Air Force Technology Safeguard Monitor Handbook
describes the role of the Defense Technology Security Administration
monitor in debris recovery and accident investigations as follows:
"If an anomaly (i.e., crash) occurs during the launch campaign
you will need to prevent technology transfer throughout the debris
recovery and accident investigation." 7 It continues:
after an anomaly occurs, the chance for technology transfer
is the highest. As a US government technology safeguard monitor
you will be overseeing the accident investigation discussions.
Failure analysis discussions are sensitive because both sides
want explanations and ask technical questions. The worst case
for possible technology transfer occurs when both the spacecraft
[satellite] and launch vehicle [rocket] are suspect; however,
technology transfer is still a problem even if the anomaly was
clearly caused by a launch vehicle [rocket] problem.
Optus B2

The
Optus B2 Licenses
On May 2, 1991, the U.S. Department of State issued export
license 483414, renewing license 384476, dated March 16, 1989.
The 1991 license permitted the export of two Hughes Model HS-601
satellites (see illustration) to Australia for delivery in space
to Aussat (later renamed Optus), Australia's national communications
satellite company.
The foreign intermediate consignee was Hughes, in care of
China Great Wall Industry Corporation, Xichang Satellite Launch
Center, Xichang, PRC.
The license was qualified by a letter dated May 2, 1991 from
the Office of Defense Trade Controls of the State Department
that sets forth limitations and provisos. In relevant part:
1. Hughes (which term includes all Hughes employees and
agents) must conform strictly to the terms of Hughes own technology
control plan with the China Great Wall Industry Corporation,
as well as to the terms of the Satellite Technology Safeguards
Agreement between the U.S. Government and the People's Republic
of China (the Agreement) and the U.S. Government's measures for
the implementation of that agreement.
* * *
5. Unless it obtains the prior separate approval of the
Office
of Defense Trade Controls of the U.S. Department of State, Hughes
must not provide any hardware or technical assistance whatsoever
to its Chinese counterparts which might assist China to design,
develop, or enhance the performance of any of its contemplated
or existing Long March launch vehicles or missiles.

The
Optus B2 Fails To Achieve Orbit
On December 21, 1992, the Hughes-manufactured Optus B2 satellite
was launched from Xichang Launch Center in the PRC.
The following description of the failure is excerpted from
the Hughes report:
A normal performing launch vehicle [rocket] would have
passed through the point of maximum dynamic pressure at 62 seconds
after liftoff. The failure occurred approximately 48 seconds
after liftoff. The launch vehicle [Long Mrach 2E rocket] was
in the transonic buffeting period of its flight, at an altitude
of approximately 7000 meters, when the failure occurred . . .8
Debris recovery began almost immediately and continued for
about three weeks.
Officials from the
China Academy of Launch Vehicle Technology (CALT) and Hughes
began to investigate the cause of the crash. Hughes President
and CEO Steven Dorfman appointed Vice President Donald Cromer
to lead the Hughes investigation to determine the cause of the
failure.9
Before joining Hughes, Cromer, had been an Air Force Lieutenant
General, and had managed the Space Division of Air Force Systems
Command. In that position, he was responsible for the design,
development, and acquisition of Air Force space launch, command
and control, and satellite systems.10
Cromer's principal assistant in directing the Optus B2 failure
investigation was Dr. Stephen L. Cunningham, a senior-level Hughes
executive and Ph.D. physicist who has worked in satellite programs
at Hughes since 1977.11
Failure
Investigation Teams
Hughes established several teams to conduct the Optus B2 launch
failure investigation. The teams comprised 27 individuals, and
their activities covered over 20 days of meetings with the PRC,
including at least 15 days of meetings in the PRC.
A Failure Investigation Team was chartered to examine all
aspects of the failure, including both the satellite and the
rocket.
A second team, called the Spacecraft Focus Team, was to limit
its focus to the satellite.
A third team, the Independent Review Team, was made up of
experts from outside the Hughes organization. It was charged
with reviewing the work of the other two Hughes teams and with
making an independent assessment of the failure.
Finally, because Hughes recognized that the findings of its
teams could be in conflict with those of the PRC accident investigators
representing the China Academy of Launch Vehicle Technology (CALT),
it established the International Oversight Team made up of three
members: one from Intelsat, one from the China Aerospace Corporation
(CASC), and the Chairman of the Hughes Independent Review Team.
The Hughes teams were organized by functional specialties
as illustrated in the chart previous.12
The organization chart identifies Peter M. Herron, who was
the Optus B2 Assistant Program Manager, as responsible for U.S.
Government/PRC coordination for the failure investigation. In
this role, Herron was the person responsible for obtaining U.S.
Government approval for all information transfers from Hughes
to the PRC during the failure investigation.13
Failure
Investigation Begins
The failure investigation began immediately, and proceeded
as shown below.14
As the debris recovery progressed, Defense Technology Security
Administration monitors who were present for the launch continued
to monitor the recovery efforts.15 Defense Technology Security
Administration monitors were also present during the subsequent
failure investigation, both in Beijing and Xichang, whenever
Hughes employees had meetings with PRC officials.
U.S. Air Force Lieutenant Colonel Allen Coates was one of
the Defense Technology Security Administration monitors. He was
present in Beijing from January 4 to 14, 1993 as a Defense Technology
Security Administration monitor for the failure investigation.
Lt. Col. Coates specifically recalls informing Hughes senior
management, including Vice President Donald Cromer, Chief Technologist
Al Wittmann, Chief Scientist Robert Steinhauer, and Optus B2
Assistant Program Manager Peter Herron of the restrictions in
Hughes' export license regarding the transfer of any information
related to the design of the satellite or the rocket.16 He additionally
advised Hughes personnel there, specifically Herron, and possibly
Steinhauer and Wittmann, that Hughes could not discuss modifications
to the fairing.17 At that time, Al Wittmann, Chief Technologist
at Hughes, reported directly to CEO Steven Dorfman.18
In the early stages
of the investigation, the PRC focused its analytic efforts on
the rocket, and Hughes examined the satellite. Both the PRC
and Hughes were seeking to determine whether their respective
hardware was responsible for the failure. Because the first visible
sign of an explosion appeared as a flame at the top of the rocket,
there was some question as to whether the satellite could have
exploded.
As part of the investigation, Wittmann, Hughes' Chief Technologist,
and the other engineers first looked into the possibility that
the satellite fuel tank structures failed. They later determined
the fuel tanks did not fail.19
Upon his return from the PRC, Wittmann had an accident that
forced him to recuperate at home. During his recuperation, he
was assisted by Spencer Ku, another Hughes engineer. In reviewing
some of Ku's analysis, it occurred to Wittmann that statements
made to him by PRC personnel regarding the structure and materials
strength of the rocket's fairing (that is, the portion of the
rocket including the nose cone that surrounds the satellite)
were not realistic.20
Wittmann was sure in January 1993, while still in recuperation,
that the fairing21 that surrounds the satellite failed, thus
collapsing and crushing the satellite.22
As the investigation progressed, Hughes scientists became
more and more certain that the fairing on the Long March 2E rocket
had indeed failed, causing the launch failure.
Hughes'
Export Administrators Deal with the Licensing Question
Hughes' Technology Export Control Coordinator, Donald Leedle,
was the focal point in the company from 1992 until 1996 for technology
licensing issues. A program or contracts manager who needed to
export a satellite would consult him for information regarding
licensing requirements. He was responsible for maintaining current
knowledge of governmental regulations related to export licensing.23
Leedle describes himself as one of the most knowledgeable
Hughes employees on the subject of the International Traffic
in Arms Regulations as they relate to communications satellites.
He says he was responsible for briefing Hughes program managers
on these regulations. He was also responsible for coordinating
licensing conditions and requirements for the Hughes programs.
He consulted with Hughes Electronics' corporate International
Traffic in Arms Regulations expert, Dar Weston, when necessary.24
Leedle says that the Optus B2 licenses, as many as 18, had
been approved before he was involved in the Optus program. Some
licenses had expired, however, and he was involved in the renewal
by the State Department of the expired licenses.25
In response to a general question about the need for a license
for a failure investigation, Leedle says that an accident investigation
might be covered by the original license, or it might need a
new license, but such a decision would be made by the U.S. Government.
He advises that technical data would require different State
Department licenses than the satellite hardware. Further, he
says that Hughes was not permitted under the International Traffic
in Arms Regulations to make suggestions that would help improve
PRC rockets.26
Leedle is aware that rockets are included on the Munitions
List and that a fairing is a part of the rocket.27
Sometime after the
Optus failure, Leedle met with a group of Hughes employees, among
them Hughes attorney Jennifer Smolker28 and Peter Herron, who
had been the Assistant Program Manager for the Optus B2 satellite,
to determine whether a license was needed for the failure investigation.29
Hughes CEO Dorfman describes Smolker as "the first point
of accountability, from my perspective, on the whole licensing
process." 30
In April 1993, Leedle most likely contacted Donald E. Majors,
Director for International Affairs at Hughes' Washington, D.C.
office, regarding Hughes communications with the PRC concerning
Long March 2E rocket fairing deficiencies. Although he does not
specifically recall the conversation, he says that he talked
frequently to Majors during that period.31
On April 9, 1993, Majors wrote a memorandum to Leedle on "License
Requirements for Long March Fairing Discussions," in which
he summarized informal discussions with the State Department
regarding the Optus B2 launch failure investigation.32 The text
read:
1. In response to our informal inquiry, the
cognizant State Department licensing official expressed the following
views:
a. Information or professional opinion on fairing deficiencies
as a potential cause of the Optus B2 launch failure probably
constitutes technical data as defined in ITAR [International
Traffic in Arms Regulations]. If Hughes decides this is in fact
the case, an export license would be required to provide such
information or opinion to the PRC. If Hughes decides otherwise,
the subject is moot.
b. If a license is required, chances of obtaining
it would
be good if Hughes could make an unequivocal case that the technical
data to be transferred could not be used for any purpose other
than increasing the safety of the spacecraft
during a new launch.
c. A license request would almost certainly be denied
if even the slightest possibility or inference, real or perceived,
remained undispelled that the technical data could directly or
indirectly impact PRC ballistic missile interests.
2. Should [Hughes] elect to submit a license
application on this subject we recommend that (a) all the technical
data to be transferred be precisely stated and (b) detailed rationale
be included to counter all potential arguments that the data
could in some way enhance PRC ballistic missile capabilities.
3. Considering the extreme sensitivity that certain
USG agencies attach to technology transfers to the PRC, we should
also give some thought to an advance softening up process.
This could include advance technical level briefings for friends
and adversaries alike, and a degree of precoordination of the
data to be released. [Emphasis added]
Majors' memorandum to Leedle was also sent to Herron and Smolker.
Additionally, copies of the memorandum were forwarded to the
following Hughes executives: CEO Steven Dorfman, P. C. Dougherty,
M. J. Houterman, W. D. Merritt and J. S. Perkins.
Majors' office served as the Washington liaison between Hughes
corporate offices and the State Department on licensing issues.
His primary contact on satellite issues at the State Department
licensing office was Kenneth Peoples.33
Peoples had issued State Department export license number
483414 to Hughes for the export of the Aussat B (later Optus
B) satellite. He says that the license defined authorized activities,
and that any activity not specifically authorized by a license
is prohibited.34
Peoples advises that rockets are on the Munitions List and
that a fairing, the nosecone that protects the satellite, is
a part of a rocket.35 Peoples does not specifically recall speaking
to Majors about the fairing, but he describes the recommendation
in Majors' memorandum as "excellent advice." The fact
that rocket information was on the Munitions List in 1993 was
well-known, he says, and Peoples has difficulty accepting that
Hughes officials would not have been aware at that time that
a license would be needed to convey to the PRC information related
to rockets.36
Mere unlicensed discussion of technical data with foreign
nationals is sufficient to constitute a violation of the International
Traffic in Arms Regulations, in Peoples' opinion. In addition
to the license restrictions, Hughes was prohibited from transferring
technology to the PRC by provisions of the U.S./PRC nation-to-nation
agreement on technology transfer.37
Stephen Cunningham,
who led the Optus B2 launch failure investigation, had also been
the Program Manager for the Optus B1, which was launched
in the PRC in August 1992. He is familiar with the International
Traffic in Arms Regulations and the Munitions List. Cunningham
agrees that Hughes needed prior, separate approval from the State
Department to provide any technical assistance that might assist
the PRC in enhancing the performance of its Long March rockets.38
Around the time of Majors' April 9, 1993 memorandum, Cunningham
recalls "specific discussions with [Defense Technology Security
Administration monitor Lt. Col.] Al Coates regarding whether
the fairing we are talking about had any relevance to ballistic
missiles, and we did not receive a specific answer from Al Coates,
but he said he would go find out from his sources." 39
Cunningham says that Hughes hypothesized that the fairing
on a commercial satellite had no relevance to ballistic missiles:
We were all very sensitive to the issue on anything that
would help the ballistic missile interest, but - and there are
a lot of things in the commercial satellite business that are
irrelevant to weapons use and so the real question was, in our
minds, is the fairing that we are talking about in the category
of commercial use only or is it in the category of missile technology?
40
On April 19, 1993,
ten days after the Majors memorandum, a senior level staff meeting
took place at Hughes to discuss how to deal with the fairing
issue. Officials at the highest levels of Hughes, including
possibly Vice President Cromer, attended the meeting, which was
held to discuss a planned trip to the PRC regarding both the
Optus B2 failure and the future launch by the PRC of Optus B3,
the satellite that was to replace the destroyed Optus B2.41
Cunningham's participation in the trip to the PRC was in connection
with his duties to discuss and resolve issues related to the
Optus B2 failure. While on the same trip, his colleague Peter
Herron was involved in negotiations regarding the Optus B3.42
By April 1993, Cunningham says, "We strongly believed
that the fairing caused the problem . . . We believed that the
fairing had to be modified in order to get insurance to launch."
43
Herron had prepared view graph slides, outlining the issues
and alternatives for senior management to consider at the strategy
meeting. One of the slides used in the briefing stated the following:
We are concerned about several aspects of the design [of
the Long March 2E fairing]. What do they fix? How do they validate
the redesign?
The USG will require a specific license if we want to discuss
the design problems. It is unlikely that we could get the license.
We would have to show that there would be no resultant
improvement in the Chinese ICBMs.44
A
'Political' Business Solution
Hughes' Director of Launch Service Acquisition, John S. Perkins,
was responsible for the negotiation of the Optus B3 launch services
contract with the PRC. In that role, he had contact with the
team investigating the Optus B2 failure. Although he was not
part of the Optus B2 failure investigation team, he was in the
PRC conducting Optus B3 negotiations while the failure investigation
was proceeding.45
Perkins recalls being aware during the failure investigation
that some Hughes engineers thought that the fairing on the Long
March 2E rocket may have failed. He recalls that there were discussions
within the company that Hughes would require the PRC to improve
the fairing, and that without improvements to the fairing, the
Optus B3 would not be launched.46 Perkins says that the negotiations
for an agreement to announce the conclusion of the Optus B2 failure
investigations took several weeks of "wordsmithing to subtly
try to imply the other party was at fault, without being at fault,
to point the finger at us or to point the finger at the Chinese."
47
The negotiations for Optus B3 were difficult, because the
PRC would not acknowledge any fault in the Optus B2 failure.
It is Perkins' belief that the Defense Technology Security Administration
eventually approved some discussions with the PRC about fairing
improvements.48
Perkins also participated in discussions with the PRC that
led to a written agreement that took the following form:
MINUTES OF MEETING HELD IN BEIJING
ON 11 TO 12 MAY 1993
BETWEEN HUGHES AND CGWIC
REGARDING THE CONCLUSION
OF THE OPTUS B2 FAILURE INVESTIGATIONS
1. On December 21, 1992 the Optus B2 satellite
was launched on an LM-2E Launch Vehicle from Xichang Satellite
Launch Center, China. At approximately 48 seconds into the flight,
the Optus B2 spacecraft exploded.
2. Based on analysis of the Launch Vehicle
telemetry, inspection of the Launch Vehicle fairing debris and
special tests, it was determined by CGWIC/CALT [China Great Wall
Industry Corporation/ China Academy of Launch Vehicle Technology]
that there is no design or manufacturing or integration flaw
in the Launch Vehicle or the fairing which caused the failure.
Hughes accepts this conclusion.
3. Based on analysis of the Launch Vehicle
telemetry, inspection of the spacecraft debris, and special tests,
it was determined by Hughes that no design or manufacturing flaw
can be found in the spacecraft which caused the failure. CGWIC/CALT
accepts this conclusion.
4. Both CGWIC/CALT and Hughes agreed to conclude
the Optus B2 investigation and use their best effort to launch
another Optus satellite by June 94.
5. During the Optus B2 failure investigation,
both CGWIC and Hughes observed strictly the requirements of the
USA/PRC agreements on technical security.
6. Both parties expressed the same willingness
to promote the existing friendly cooperation between them. Hughes
expressed the willingness to purchase Long March launch services
for other future satellite programs, and CGWIC expressed the
willingness to influence its partners to purchase Hughes' satellites.
Signed on the 12th day of May 1993
Donald L. Cromer Wang Dechen
John S. Perkins Chen Shouchun
Perkins describes this agreement as an agreement not to publicly
blame the fairing as the cause of the failure. Perkins says of
the agreement:
Politically we could not write down on paper that the fairing
had failed and that they were at fault. It was a non-starter
in China. They were very concerned that we would say that. This
document was trying to say we are not going to say that. Now,
go fix the fairing. 49
Hughes' intermediary
in the PRC was Bansang "Bill" W. Lee, who worked in
the Hughes Beijing office from 1991 until around October
1994 as a salaried employee.50 As Hughes' chief representative
in Beijing, he had three duties: marketing Hughes satellites
in the PRC; serving as a liaison between various Hughes organizations
and the PRC; and providing logistics support for all Hughes visitors
to the PRC.51
Although Bansang Lee was not actually a member of the Optus
B2 failure investigation team, he was present at meetings in
the PRC and was involved in the negotiations that led to the
May 12 agreement between Hughes and China Great Wall Industry
Corporation not to blame each other for the launch failure. He
was also involved in negotiations for the Optus B3 launch.52
Lee's major involvement in the failure investigation was crafting
an acceptable public explanation as to the cause of the failure.
The PRC would not accept that the Long March 2E rocket was at
fault, and Hughes was almost certain that the satellite had not
caused the failure. Lee says that in the May 12, 1993 agreement
each side stated: "I have no objection to your position
. . . and you have no objection to my position. Basically, the
conclusion is no conclusion." 53
Lee says that his involvement in efforts between April and
October 1993 was generally along the lines of persuading each
side not to point fingers at the other. He says that he was not
directly involved in attempts by Hughes to convince the PRC that
the fairing was the problem, although he was aware that a number
of people within Hughes believed that. He was also aware of at
least one, Harold Rosen, who did not hold that belief.54
Lee further says that in the negotiations, during which Lee
served as Hughes CEO Dorfman's liaison to PRC Minister Liu Jiyuan,55
Minister Liu confirmed Hughes' understanding that once a suitable
agreement had been signed, the PRC would be willing to consider
making modifications to the Long March 2E rocket before the next
launch.56
In addition, Lee says that Hughes "is not saying how
to fix it, but wording [sic] requirement that they have to finally
fix it." Lee says he was aware that a number of Hughes engineers,
particularly Al Wittmann, believed that the fairing had indeed
failed.57
In June 1993, Hughes
Chief Technologist Al Wittmann wrote a paper analyzing how he
thought the fairing had failed, and how the fairing could be
improved to prevent a similar failure in the forthcoming
Optus B3 launch. The paper sought permission within Hughes to
communicate the results of his analysis to the PRC. Wittmann
says he discussed the recommendations in his paper with Peter
Herron, who was coordinating the launch failure investigation
with the PRC; Hughes Vice President Donald Cromer; and Stephen
Cunningham, who was heading up the launch failure investigation.58
Wittmann recommended that Hughes not launch the Optus B3 on
the Long March 2E rocket unless the PRC made improvements to
the fairing. He says that 70 to 80 percent of the Hughes team
members agreed with him, and that Cromer, Cunningham, and Herron
supported his view that the Optus B3 should not be launched without
changes to the fairing.59
When Wittmann discussed his paper with Herron, Herron responded
by telling Wittmann that, unless the fairing recommendations
in the paper were simplified considerably, he was not willing
to ask the U.S. Government for approval to share it with the
PRC. Wittmann says Cunningham had also asked him to revise the
paper for the same reason. 60
Hughes CEO Dorfman also recalls discussions with Wittmann
about the fairing:
Q: Would you describe the changes that .
. .Wittmann may have brought to your attention as changes which
would improve the fairing?
A: Well, the only thing I can remember is
that Mr. Wittmann . . . felt that the fairing . . . had an overlap
problem, and that there would be a gap that could be caused during
ascent between the two halves of the fairing, and that that gap
might cause a pressure differential which would separate the
fairing.
Q: Would that suggestion constitute, in your
view, an improvement to the fairing?
A: I don't know.
Q: Is it a modification to the fairing?
A: If they made a change, it would have been
a modification.
Q: So Mr. Wittmann recommended something
which, if it had been accomplished, would have been a modification
to the fairing?
A: Yes. 61
Additionally, Hughes Vice President Cromer recalls the following
discussion with Wittmann about the fairing:
Q: When Mr. Wittmann first approached you
about his concerns regarding the fairing, do you recall some
of the technical aspects that he mentioned . . . ?
A: Yes.
Q: Can you tell us what some of those were?
A: He was concerned about two aspects particularly.
One is the strength of the rivets that held the fairing together
and this was an issue of having adequate strength to withstand
the launch loads but still having sufficient ability to open
the fairing when you needed to. So it's a balance of strength
versus separating the fairing under the right conditions. Also
the nose cap and its design and how it might be affected by the
loads during the ascent. 62
Hughes launch failure investigators Herron and Cunningham
subsequently prepared a group of viewgraph slides that simplified
the contents of Wittmann's paper. Herron, who was responsible
for coordinating with the PRC, then submitted these to Defense
Technology Security Administration monitor Al Coates for approval.
Coates' signature approving the transfer of this information
to the PRC appears on a facsimile transmittal sheet, dated June
25, 1993.
Lt. Col. Coates
says he does not recall approving this transfer, and he doubts
that he would have ever approved the disclosure of such prohibited
information. He further says he did not have the authority
to approve the disclosure of information that could have improved
the PRC rocket. He also says that it was always clear to Hughes
that no data that could improve the rocket could be transferred
to the PRC.63
Generally, Coates recalls that the Defense Technology Security
Administration always emphasized in briefings for Hughes employees
the prohibition against improving the rocket. He says that Hughes
personnel were very knowledgeable about the export control process,
and that Herron undoubtedly knew of the restrictions regarding
rocket improvements.64
Coates specifically recalls telling Herron that he could not
discuss the design of the fairing with the PRC.65
Coates says he maintained a program file at the Defense Technology
Security Administration that contained all his approvals related
to the Optus B2.66 Such a file could not be found among the materials
provided to the Committee by the Defense Technology Security
Administration.
Hughes failed to respond to the Committee's interrogatories
(which included a request for documents) regarding these approvals.
Donald Leedle, who was responsible for Hughes' technology
export control, says Herron contacted him to inform him that
Coates had approved communicating the information on improving
the fairing to the PRC. In Leedle's deposition, the following
exchange regarding improvements to the Long March 2E rocket occurred:
Q: Does this document suggest specific changes
to the Long March 2E fairing for the Hughes satellite that would
improve the fairing?
A: At the bottom of the page it says. 'Add
a bracket or block to prevent any possibility of overlap of the
two fairing halves.'
Q: What about on page 2?
A: 'Increase the strength of the rivets along
the separation line.'
Q: So, in your view, does this document propose
specific technical improvements to the fairing?
A: I think they are fairly generic. Add a
bracket and strengthen a rivet is not very specific.
Q: Are those improvements to the fairing?
A: They may be.
Q: Is Mr. Herron suggesting in his letter
that they are?
A: He certainly feels that if these things
are accomplished, that there is less likelihood of it failing.
Q: So would you view this letter as Mr. Herron's
statement that these changes would improve the fairing?
A: Well, I'm not sure 'improve' is
a difficult word. It would prevent failure It might prevent
a failure.
Q: Mr. Wittmann suggested improvements to
the fairing in his letter, correct?
A: Uh-huh.
Q: Mr. Herron in a letter to Mr. Lee is now
suggesting changes need to be made to the fairing. Those changes
presumably would improve the fairing, would they not?
A: I don't know the answer to that.
Q: I'm asking you to look at Mr. Herron's
letter you had discussions with Mr. Herron and tell
me whether you think he is suggesting things that would improve
the fairing?
A: He is making recommendations to prevent
a failure.
Q: By 'prevent a failure,' would you say
that improving the fairing would help prevent a failure?
A: Something would have to be done to the
fairing to prevent a failure.
Q: Improving the fairing is what this letter
is about; is that correct?
A: Uh-huh.
Q: And you've already told us that the fairing
is a part of the launch vehicle; is that correct?
A: That's correct.
Q: So the improvements to this fairing, it
logically follows, would result in improvements to the launch
vehicle. Do you agree?
A: If they were actually improvements.67
In Cunningham's deposition, the following exchange about improvements
to the fairing took place:
Q: So, in your view, that doesn't constitute
an improvement in the fairing?
A: If they do these correctly, and they have
to define correctly, this would improve the fairing. But if they
do but without further analysis, this would not improve
the fairing. This in itself does not improve the fairing.
Q: Is it a modification of the fairing?
A: Yes.
Q: I want to go back just briefly to Exhibit
1, paragraph 120.9, defense service; it's on the second page
of Exhibit 1.
'120.9 (a), Defense service means: the furnishing of assistance
to foreign persons,' skip a little bit,'whether in the United
States or abroad in the design, development, engineering, manufacture,
production, assembly, testing, repair, maintenance, modification,
operations, demilitarization, destruction, processing or use
of defense articles.'
Is - would these suggested improvements constitute a modification
of the fairing?
A: Yes, they would.
Q: To modify a fairing or to modify a defense
article, do you need a license - according to what you read in
ITAR [International Traffic in Arms Regulations] earlier?
A: Yes, we do.
Q: And did you obtain a license to provide
this information to the Chinese?
A: No.68
Leedle says he was surprised that Herron, Hughes' Assistant
Program Manager for the Optus B2 and the person responsible for
coordinating the failure investigation with both the U.S. Government
and the PRC, bypassed him and approached the Defense Department's
Coates directly. Leedle acknowledges that the purpose of Wittmann's
fairing recommendations was to prevent the rocket from failing
in future launches. Leedle and Cunningham acknowledge that improvements
to the rocket required a State Department license, and that,
to the best of their knowledge, no such license was ever applied
for.69
On July 15, 1993,
Hughes CEO Dorfman wrote expressing his concerns about the cause
of the Optus B2 launch failure to PRC Minister Liu Jiyuan,
President of China Aerospace Corporation, in care of Hughes'
Bansang Lee, stating in part:
After listening to Wang Dechen's [the PRC designer of the
Long March 2E rocket] presentation last week, I've become very
concerned that we will not convince our customer and insurers
that it is safe to launch Optus B3.
I emphasize that you must 1) demonstrate a thorough and
objective evaluation of potential causes for the accident, and
2) make appropriate design and process changes to prevent
recurrence, even if a definitive cause cannot be identified.
Our people have made some specific suggestions which
I urge you to consider.70 [Emphasis added]
On July 18, 1993, Bansang Lee reported to Dorfman the results
of the meeting with Minister Liu at which he delivered Dorfman's
letter. Lee wrote about the PRC's strong negative reaction to
Hughes' statements that appeared to blame the PRC rocket for
the Optus B2 failure, in violation of the May 12 agreement:
Mr. John Perkins letter of July 9, 1993 clearly pointed
out the [Long March 2E rocket's] fairing was the cause of the
launch failure . . .
It is true that it looks like the whole world appears to
believe the trouble was caused by the rocket . . . CGWIC [China
Great Wall Industry Corporation] has reasons to believe that
Hughes is making a trap to get them . . . If they agree to make
any change to the fairing now, they are walking into the trap
themselves.71
As Bansang Lee continued to negotiate, he says he thought
that Hughes Chief Scientist Robert Steinhauer, who had worked
closely with the PRC for almost ten years, might be able to help
allay the PRC's concerns.
On August 5, 1993,
Bansang Lee wrote to Hughes CEO Dorfman suggesting that Steinhauer
bring the Optus B2 failure report to the PRC and meet with
the chief designer of the Long March 2E rocket, Wang Dechen,
to go over the findings.72
On August 15, 1993, Hughes and China Great Wall Industry Corporation
issued a joint news release, reported in Space News, stating
that although no design flaws were found, both companies would
make improvements to their products. Space News quotes an insurance
broker as saying that, "evidence points to a structural
flaw in the rocket's fairing which probably imploded during launch."
It also quotes a U.S. satellite underwriter as saying the companies
had narrowed the cause of the launch failure to a few possibilities,
but struck a compromise on the announcement because they are
still doing business together.
Hughes also wants to support the Long March because the
company is concerned about becoming overdependent on the Arianespace
launch consortium of Evry, France.73
On August 23, 1993, Steinhauer went to the PRC and met with
the designer of the Long March 2E rocket, Wang Dechen. Since
1985, Steinhauer had been Hughes' primary contact with the PRC
on the use of their rockets. He also served as a consultant to
the Optus B2 failure investigation team from January 1993 through
October 1993, attending many of the failure investigation team
meetings, and also meeting with the PRC regarding the failure
investigation.
The purpose of Steinhauer's August meeting in the PRC was
to try to help resolve things between the two companies. In particular,
Steinhauer focused on Wang Dechen, the designer of the Long March
2E. Hughes believed that Wang Dechen was the key PRC individual
who had to be turned around.
On September 14,
1993, Hughes Chief Scientist Steinhauer wrote a memorandum to
Hughes Vice President Cromer suggesting a hard negotiating position
with the PRC on the issue of the fairing failure. The memorandum
said: ". . . Hughes should make an unequivocal statement
to Minister Liu Jiyuan that Optus B3, or any other Hughes spacecraft,
will not fly on the LM-2E without modifications to their launch
vehicle fairing."
The memorandum also describes Wang Dechen as "digging
in his heels" against the idea of a unified presentation
identifying the failure cause for the insurance community. Cunningham
advises that earlier in the investigation Wang Dechen had publicly
stated that the rocket was not the cause of the failure.74
Hughes Vice President Donald Cromer says that it was his decision
whether Hughes would launch Optus B3 on a Long March 2E rocket.
His decision was that Hughes would not launch unless the China
Academy of Launch Vehicle Technology made improvements to the
fairing.75
In a September 9, 1993 message to Cromer, Bansang Lee made
a number of recommendations related to future business relations
between Hughes and the PRC in preparation for the Optus B3 insurance
underwriters' briefing that was scheduled later in September.
Bansang Lee wrote:
In reality by insisting that the rocket has a problem at
the fairing will do [sic] harm to Hughes in the following major
areas:
It will be even more difficult for the rocket to obtain
insurance. This will make the Optus B3 program more expensive
and more difficult to resolve.
Furthermore, it will make the APT II [the PRC-controlled
Asia Pacific Telecommunications Satellite Co.'s next Hughes satellite]
more difficult to obtain insurance as well. This will hurt Hughes
a lot more than CGWIC [China Great Wall Industry Corporation].
We will have a 'war' to fight, not only with CGWIC, but
with China in general. This will not only hurt our satellite
business in China but will generally be harmful to all Hughes
activities in China for years to come.
What do we get out from [sic] this? I could not think of
any [sic] that is good and useful to Hughes. The only small thing
that I could think of is that in the future we could claim better
reliability statistics on our satellites.
If we swallow this one and let our Chinese friends off
the hook, it will actually do more good for Hughes . . .76
On September 10,
1993, Hughes Vice President Cromer asked Bansang Lee to bring
Cromer's concerns to the attention of the highest levels of the
PRC:
However, of even greater disappointment is the continued
insistence by Wang Dechen [the PRC's Long March 2E rocket designer]
that we change the conclusion of our failure investigation. He
has signed an agreement that he accepts the results of our investigation
yet he continues to demand we modify the results to suit his
view of the accident . . .
We (Hughes and CALT) must make a full disclosure of all
relevant facts and data surrounding the accident to the insurance
community . . .
It is mandatory that we both make whatever changes are
necessary to add margin to our designs. We are doing so on the
satellite side and are prepared to disclose these at the insurance
briefing. The Chinese must be able to state that they will do
likewise . . .
They cannot be superficial improvements - they must be
substantial and directly related to a possible failure cause.77
On September 15, 1993, the Hughes official coordinating the
launch failure investigation with the PRC, Peter Herron, wrote
to Bansang Lee about the insurance briefings. Herron asked Lee
to inform the PRC that Hughes was willing to remove all information
from the insurance briefing related to the Long March 2E rocket
from its presentation at the insurance briefing. But Hughes would
do this only if the China Academy of Launch Vehicle Technology
presented the data that Hughes was deleting. In his letter, Herron
wrote:
While we would not plan to talk about the fairing debris,
it is important for full disclosure that CALT [China Academy
of Launch Vehicle Technology] also address the following:
Debris - The CALT report makes blanket statements that
there were no delaminations. However, it is obvious that there
were a number of small delaminations, both on the inside of the
cylindrical portion of the fairing and along one edge of the
nose cap. They [CALT] must explain why they think these occurred
and what the relationship to the event [crash of the Long March
2E] is, if any . . .78
By late September, Hughes and the PRC had decided, pursuant
to their May 1993 agreement, that Hughes would not brief the
issue of the fairing to the insurers.
The PRC had earlier
signaled to Hughes' Bansang Lee that it would consider making
modifications to the fairing for the Optus B3 launch.79 Hughes
Vice President Cromer confirms that Hughes made a decision to
go forward with Optus B3 because the China Academy of Launch
Vehicle Technology had committed itself to modifications to the
Long March 2E rocket's fairing.80
On September 30, 1993, Hughes and PRC representatives met
with the Optus B3 space insurance underwriters in London to discuss
the conclusions and results of the Optus B2 failure investigation.
Cunningham, as the head of the Hughes failure investigation,
led the company's presentation.81
At the time of the insurance briefing, the Hughes final investigation
report was not yet finished. Although Cunningham was the author
of the Hughes Optus B2 Failure Report, he says he did not distribute
the report to anyone outside of Hughes, and he does not know
whether anyone else at Hughes did so.82
Cunningham says that the Hughes failure investigation report
was sufficiently technical that Defense Technology Security Administration
approval would have been necessary for it to be exported. He
does not know whether the report was ever given to the PRC, but
he doubts it was.83
Cunningham says that the U.S. insurance underwriters may have
been separately briefed by Hughes about its concern that the
Long March 2E fairing was defective and needed modifications.
Hughes claims that the Defense Technology Security Administration
was not present at the insurance briefing because it chose not
to attend. Defense Department monitor Coates claims he was told
by Hughes that no PRC representatives would be present at the
briefing.84
Hughes Vice President Cromer testified that C. Michael Armstrong,
at that time Chairman and Chief Executive Officer of Hughes Electronics
Corporation, was generally aware of the analysis of the 1992
failure. Cromer updated Armstrong on the progress of the investigation.85
Armstrong, however, testified that although he was aware of
the Optus B2 failure, he could not recall any information about
a failure investigation.86
The
Optus B3: Hughes' Efforts to Improve
the Long March Continue
Between October 1993 and August 1994, when the Optus B3 was
successfully launched, Hughes continued its efforts to have the
PRC improve the Long March 2E fairing.
On October 13, 1993, Peter Herron, in his role as Program
Manager for Optus B3, wrote to Bansang Lee regarding changes
to the Long March 2E. Herron wrote, in part:
4. We need to discuss the possible changes to the LM-2E
[Long March 2E]. How do we get the changes made?
I suspect it is unlikely that CALT [China Academy of Launch
Vehicle Technology] will recommend changes to the fairing, since
that might be seen by them as an admission that something was
wrong. (Why else make a change?)
They have stated that they would make changes that their
customers require. This was stated in the press release, was
stated by Wang Liheng at the dinner with Don Cromer in September,
and was stated by Wang Dechen during the meeting with the underwriters
in London. However, we are not LV [rocket] experts and are not
in a position to make
recommendations for improvements.
Further, the USG would not be likely to allow us to
make recommendations in the current environment.
This is my idea. Last summer we requested that CALT respond
to our concern with the nose cap (you will recall the four viewgraphs
we prepared and showed to Wang Dechen [the PRC's Long March 2E
designer] as well as the bad reaction that resulted).
I think we can use these same viewgraphs to request that
CALT examine some 'Hughes requested' changes to the fairing.
Specifically, we can ask for CALT ideas on how they would implement
changes that would,
1. Add a bracket or block to prevent any possibility of
overlap of the two fairing halves,
2. Increase the strength of the rivets along the separation
line. . . [Emphasis added]
The Defense Department's
Lt. Col. Coates says that, had he been asked, he would not have
approved the transmittal of this information to the PRC. He
also says that Hughes personnel knew that each separate transmission
of information to the PRC required specific approval.87
On October 20, 1993, Peter Herron, Hughes' program manager
for the Optus B3, wrote to Chen Shouchun, Vice President of the
China Great Wall Industry Corporation, regarding Optus B3 meetings
scheduled for November 1993 at Hughes. One topic of Herron's
letter is ". . . discussions of ways to improve margins
for the next launch. CALT [the China Academy of Launch Vehicle
Technology] has already committed to make some changes to the
LM-2E [Long March 2E rocket] in accordance with our needs."
Hughes and the PRC held design meetings in November 1993,
to discuss the proposed modifications to the fairing.
The Optus B3 was licensed by the Commerce Department, not
the State Department. Other than the license for the Optus B3,
which was approved by the Commerce Department, Herron did not
submit any Optus B3 fairing improvement documents to the U.S.
Government for approval.
Steven Burke, a structural analysis engineer at Hughes and
principal investigator on the Optus B2 investigation, recalls
attending a number of Optus B3 design review meetings with the
PRC. During the early portion of the Optus B2 failure investigation,
Burke had been responsible for analyzing Optus B2 rocket telemetry
data supplied by the PRC. Burke and fellow engineer Spencer Ku
had determined, along with Hughes' Chief Technologist Al Wittmann,
that the fairing had caused the failure.88
On May 9, 1994,
Burke wrote a detailed technical paper entitled "Optus B3/LM-2E
Fairing Design Review," discussing a meeting with the
PRC that occurred on May 2, 1994 regarding fairing improvements
to the Long March 2E needed for the upcoming Optus B3 launch.
He says the meetings were both political and technical in nature:
political in that the PRC was unwilling to admit fault, while
from a technical perspective, they were willing to make changes.
Burke further says that as a result of the Hughes investigation,
Hughes had asked the PRC to strengthen the weak parts of the
fairing.89
In the paper, Burke wrote that the PRC proposed changes to
what it termed the "already adequate" capabilities
of the fairing. His paper continued, identifying PRC proposals
for the following changes to the Long March 2E rocket's fairing:
a. Increased number of nose cap attachment screws from
21 to 41. Increased number of cover strip attachment screws from
12 to 23.
Comment: These changes add strength to joints that would
not need strengthening if the dome were stiff enough.
In my opinion, these changes do not address the real problem
with the nose cap design, nor do they constitute an effective
"crutch" that would preclude another fairing failure.
They do offer some integrity enhancement, but against loads that
could best be
limited by maintaining the as-designed dome configuration.
In short, these [the fairing changes proposed by the PRC]
are token changes that are easy to implement but do not preclude
another fairing failure because they neither stiffen the sawcut
edges of the dome halves nor stiffen the dome base frame at its
discontinuities.90
Burke's paper went on to discuss other technical deficiencies
and questioned how Hughes could get the PRC to propose truly
effective changes to the Long March 2E rocket's fairing design.91
Burke recalls Peter Herron, who was now Program Manager for
the Optus B3 satellite, telling him that Herron had provided
documentation to the PRC suggesting changes to the Long March
2E rocket's fairing during the Optus B2 failure investigation.92
On July 30, 1994, Herron wrote to the PRC requesting additional
information about the PRC changes to the fairing. Herron showed
his letter to Burke, and asked for his views on the additional
modifications proposed by the China Academy of Launch Vehicle
Technology. Burke says that he and others provided Herron with
questions on the CALT proposed changes.93
On August 4, 1994,
Hughes' Chief Technologist Al Wittmann wrote to Vice President
Donald Cromer, stating that he believed the changes to the fairing
proposed by the PRC were adequate for the upcoming Optus
B3 launch.94
In August 1994, Burke says he attended a Hughes senior management
meeting to review the changes made by the PRC to the fairing
for the scheduled Optus B3 launch. The briefing slides for the
meeting are dated August 8, 1994. By the time of this meeting,
Burke says that Wang Dechen, the PRC designer for the Long March
2E rocket, had told him that the PRC had made improvements to
the rocket's fairing. Burke further says that his review of the
documents from the August 8 briefing show that the changes made
were a combination of PRC ideas and Hughes ideas.95
According to Donald Leedle, responsible for Hughes' technology
export controls, a design review in which Hughes provided information
to the PRC should have required a State Department license.96
The Optus B3 was launched successfully on August 28, 1994,
aboard a PRC Long March 2E rocket.
