Hello everyone,

I am doing a research paper on the Peace Pearl project to upgrade the PLAAF J8IIs. I was after some information and hoping that someone here might have the answers or at least an idea.

-Does anyone know if the two prototypes ever flew? Either afterwards in China or in the US. It appears that taxi testing was done and I have my doubts they flew but I can't confirm it either way.

-What happened to the two prototypes after they were returned from the US? I have a Bard AI quote from a book saying one was scrapped and the other was put in a museum in Shengyang (presumably the SAC museum) and that the one purporting to be one in Beijing is actually a J8II that's been mocked up (possibly with one of the returned avionics kits) to look like a Peace Pearl aircraft. Again, I can't corroborate this and the book that's quoted is quite expensive and I think that was the only passage in the book anyway.

These are my two big questions I can't quite corroborate right now so if anyone could help I would be very appreciative. Chinese sources are fine too, if you have them- my Chinese is pretty rusty at the moment but I have access to a much better translator than I am!

Thanks very much.
 
'PEACE PEARL’ AVIONICS WORK
Progress on an F—8-2 “Peace Pearl” avionics upgrade with the U. S.’s Grumman Aerospace Corp. and USAF’s Aeronautical Systems Div. has been affected but not seriously slowed by U. S. technology transfer sanctions, according to Xu. Although the U. S. government forced Chinese engineers at Grumman in Bethpage, N. Y., to leave the project, work continued independently on each side of the Pacific,
he said.

Chinese engineers assigned to the Peace Pearl program were beginning to return to the U. S. during Aviation Week’s visit. The $500-million Peace Pearl project is funded under a U. S. foreign military sales (FMS) program. It adds a modified Westinghouse AN/APG 66 radar and fire control computer to the aircraft, Litton LN-39 internal navigation system and head-up display. Mission and air data
computers also are incorporated.

Aviation Week’s editors were allowed to inspect the J-8-2 Peace Pearl cockpit, which has an autopilot with altitude hold and stability augmentation, as well as UHF, VHF and single sideband HF radios. The aircraft also has radar and missile detectors and a jammer system. The windshield is heated. Pilot visibility is limited, however, by two curved windshield support braces and a rear fuselage “spine” that runs from the cockpit aft to the vertical tail.

Except for the head-up display, the cockpit layout and appearance was comparable to an early generation USAF/Mc-Donnell Douglas F-4 cockpit. Cockpit instrumentation included an ILS, and standard red instrument lights are provided for night operations.

The F-8-2 has an aft fuselage folding ventral fin that is deployed in flight and an all-flying horizontal stabilizer. A popout ram-air emergency turbine is mounted under the fuselage. Chaff and flare dispensers and a drag chute are mounted on the tail.

The aircraft has seven external stores stations capable of accommodating bombs, 23-mm. gun pods, medium-range air-to-air missiles and air-to-ground missiles. It has a single-point refueling receptacle and provision for centerline and pylon drop tanks.

The surface finish on the fuselage shows excellent workmanship, with flush panel-to-panel joint mating, smooth fairing installation and riveting. This detail carried over to noncritical areas such as wheelwell interiors.

[ ]

The initial Peace Pearl contract for updating the F-8-2 covered 50 kits and five spares. Plans to flight test two aircraft at Edwards AFB in California this year have been delayed.

Grumman is now lobbying the U. S. government for a lifting of the technology transfer ban on the aircraft. Chinese J-8-2s with the Peace Pearl upgrade are intended to be deployed along China’s border with the Soviet Union. The supersonic fighter is the “high” component of
China’s high-low defensive fighter mix. Before the sanctions, Peace Pearl avionics were restricted by the U. S. govemment to use in China only.

Shenyang Aircraft Corp. has built more than 100 F-8-ls and “several dozen” standard F-8-2s, according to Xu Guo Sheng. Both types are in service with the Chinese air force. Neither has been exported, he said.

The entire fuselage sections for both the F-8 and the F-8-2 are fabricated in Shenyang along with most subsystems. Avionics and engines are purchased from outside suppliers and installed in the last stages of assembly.

Peace Pearl was covered in 1990-1991 Janes All The World's Aircraft, I don't have this year sadly. 1987-1988 has this:
In early 1986, US government approval was given for American companies to bid for the avionics upgrade under FMS (foreign military sales) regulations. The initial requirement is for 50 shipsets, plus five spare kits, of an avionics suite comprising a fire control radar, inertial navigation system, HUD, mission and air data computers, and a databus. The upgrade programme has the US name Peace Pearl. Requests for proposals were issued to US industry in March 1987, and contract awards were expected in the second half of the year. The first of these, for the fire control system, was awarded to Grumman Corporation on 5 August 1987. Two J-8 IIs are to be delivered to the USA in early 1989 for flight test and certification of the upgrade package, with kit deliveries scheduled for 1991-95. The improved version is intended for service in Manchuria and along China’s northern border with the USSR. The US avionics will be approved only for J-8 IIs for use within China, and other Western alternatives are being sought to enable the aircraft to be exported
Which at least clarifies the numbers (I've seen 50 and 55 mentioned)

PEACE PEARL PROGRAM

Following decades of virtual hostility toward one another, relations between the People's Republic of China and the United States gradually began to thaw during the 1970s and 1980s. Several factors led to this change including President Richard M. Nixon's visit to China in 1972, negotiations during the Jimmy Carter administration, granting of "most-favored nation status" to China, and President Ronald Reagan's visit in 1984. This created a climate conducive to improved relations between the two superpowers. The Chinese faced an increasing threat from the Union of Soviet Socialist Republics, who had amassed a significant military forcealong the Sino- Soviet border. Consequently, the Chinese made overtures to the United States for technological assistance in developing subsystems for their new F- 8II interceptor aircraft. Assistance such as this fell within the realm of the Foreign Military Sales program and the United States had to tread lightly andtake existing agreements with friendly nations into consideration. The United States especially did not want to damage its alliance with Taiwan.

The American government also remained concerned about China's ability to protect the security of any technologies provided to them under the program. However, the possibility of building "an enduring military relationship" with the Chinese as a way of countering and balancing the Soviet threat in East Asia outweighed these concerns. Representatives from both countries had outlined the program by 1984 and the Aeronautical Systems Division (ASD) was awareofthe proposed sale early in that year. Responsible for overseeing the program, ASD would develop, test, and acquire the system(s)needed. This would be accomplished through the Foreign Military Sales program by an American contractor. In May 1984, a Chinese delegation came to the United States and visited military, industrial, and government organizations, including Wright Patterson Air Force Base. During 1986, ASD continued the contractor selection process and received the mock-up of an F- 8II from China. Officials from ASD arranged for the mock- up, which arrived in a bamboo crate, to be stored in Hangar 255. Late in the year the Chinese established a liaison office at ASD and in January 1987, ASD hosted a Peace Pearl Configuration/Training Conference .

In May 1987 , Secretary of the Air Force Edward C. Aldridge, Jr. , visited ASD to inspect the mock-up and learn about Peace Pearl. After three contractors submitted proposals, ASD awarded the contract to the Grumman Aerospace Corporation. Program officials anticipated more bids, but approximately 15 other companies had dropped out of the competition for various reasons. As Grumman undertook the contract, frequent roadblocks hindered the company's ability to provide the services required. The persistent lack of technical data on the new Chinese fighter and frequent design changes severely limited the company's ability to do its job. Despite this, work progressed and the Air Force arranged for two F- 8II aircraft to be brought to the United States in January 1989. To accomplish this, ASD sent several engineers to China with an American airfield survey team to help the Chinese prepare their aircraft for shipment. The team evaluated the airfield's capability to handle a giant C-5B Galaxy and advised Chinese officials how to effectively pack and protect the aircraft and related equipment to make the best use of the transport plane's cargo capacity. The airlifter successfully transported the F- 8IIs , disassembled into three pieces, to the United States .

Just as Peace Pearl appeared to be well on the way to successful completion, a major world event stopped all progress dead in its tracks. In June 1989, Chinese forces committed an act of repression that again changed U.S. foreign policy toward the communist country. The Tiananmen Square incident, where Chinese soldiers fired on civilian demonstrators, caused President George H. W.Bush to suspend all foreign military sales to the People's Republic of China in retaliation for the human rights violations. Consequently, the Air Force denied access to Chinese personnel at Peace Pearl work areas at Grumman and Wright- Patterson. The Chinese reacted to the president's sanctions by temporarily halting payments to the program trust fund. Grumman had performed ground tests on the aircraft and was approximately five months away from beginning flight testing when the Chinese abruptly announced they were terminating Peace Pearl. Chinese officials claimed the suspension had caused unacceptable cost increases. Initially, the United States declined to return the two F-8IIs to China because of the existing presidential suspension, but this was lifted in February 1992 and the aircraft were returned by ship.

Despite vast cultural and technological differences, Peace Pearl was well on theroad to success when China terminated the program. This is unfortunate because Peace Pearl could have led to more cooperative ventures between the two nations. Regrettably, several factors slowed the progress of Peace Pearl and led to cost overruns. China's inherent secrecy impaired Grumman's ability to do its job, and the lack of a standardized aircraft design frustrated those working on the system. Still, those involved with the program fondly remember the personal relationships they developed with the Chinese as they worked through cultural barriers.

From Splendid Vision, Unswerving Purpose - Developing Air Power for the United States Air Force During the First Century of Powered Flight. I think this answers the "did they fly" question - ASD/Wright-Patterson were heavily involved with Peace Pearl.

I have that edition of Jane's - Peace Pearl is covered in one single paragraph on page 42. If desired, I'll gladly transcribe the section over the next few days.
 
The 1990 Jane's entry does provide a few additional details, e.g. with respect to onboard subsystems:

Peace Pearl. Title under which, in a joint Chinese/US programme, USAF’s Aeronautical Systems Division is sponsoring an FMS (foreign military sales) avionics upgrade for the J-8 II. A 5 August 1987 contract to Grumman Aerospace corporation, due for completion in January 1995, calls for 50 shipsets, plus five spare kits, of an avionics suite comprising a fire control system, inertial navigation system, HUD, mission and air data computers, and a databus. Under subcontract to Grumman, Westinghouse is developing the fire control system (modified AN/APG-66 radar, fire control computer, backup control and interface unit, CW illuminator, fire control software, variable-speed constant-frequency power generation system and logistics support), while Litton will supply the LN-39 INS and the HUD. Two J-8 IIs have been delivered to Grumman for flight test (at Edwards AFB), followed by certification of the upgrade package, with kit deliveries scheduled for 1991-1995. The Peace Pearl version is intended for service in Manchuria and along China’s northern border with the USSR.

Thanks! Very very useful stuffs here.

Bard has told me it is China's Nuclear Weapons: A History by Ming-Yen Tsai but there no book by that name. Ming-Yen Tsai, however, did write one book called "From Adversaries to Partners: Chinese and Russian military cooperation after the Cold War."

I suspect this might be the book and Bard has it wrong- it got a lot of things wrong like the authors of the books. Originally it said Adversaries was written by a guy named Weitz. To be honest I'm not actually terribly bothered as I don't think it effect things at this point. It's a nice to know though.

Actually I've got back and asked Bard again for information on it as they've updated the thing since and now it professes to know even less. So that's helpful! It's been an interesting experiment using it.

 
Had a look through my collection.

SIPRI Research Report No. 11
CHINA’S ARMS ACQUISITIONS FROM ABROAD A QUEST FOR ‘SUPERB AND SECRET WEAPONS’
BATES GILL AND TAEHO KIM
The most prominent FMS programme was the Peace Pearl Program.
This programme, initiated by the US Air Force and worth $550
million, contracted Grumman Aerospace to provide systems definition
and full-scale development of 55 avionics and fire-control kits for
Chinese J-8II fighter aircraft as well as provide management services,
operational support and support equipment, initial spares, and flight
and related computer software data. Grumman subcontracted
Westinghouse to develop 55 fire-control systems, including an
AN/APG-66 radar, fire-control computer, back-up control system,
databus and fire-control radar. According to one Air Force spokesman
at the time, the deal would include components comparable to early
F-16 technology. The deliveries of the kits were to take place in
early 1992.
Development of the US Peace Pearl Program continued briefly after
June 1989 but was cancelled in April 1990 by China, owing to
escalating costs and unsatisfactory delivery times resulting from the
decision by the US Department of Defense not to release the complete
avionics kits to China until some undetermined date in the future.6
Some production equipment related to the munitions modernization
programme had been transferred to China, but the final production
plant had not been opened when the programme was suspended in
June 1989.
6 ‘China terminates F-811 upgrade with USAF’, Defence, July 1990, p. 422; and interview
with PLA Air Force colonel involved with the Peace Pearl Program, Oct. 1994.
On 22 December 1992, the State Department announced that the USA would return
equipment to China under the four US Foreign Military Sales programmes.
The decision covered the reimbursement of unused funds in
the Chinese FMS account, the shipment of items which China had
bought as part of the FMS agreements and the return of Chinese
equipment brought to the USA as part of the FMS agreements
(including two J-8II prototypes).8 According to Chinese military
sources who were involved in the Peace Pearl Program, these prototypes
were returned ‘as is’, without the avionics upgrade kits.
 
On 5 August 1987. while the J-8 II flight test programme was still at a relatively early stage, the Grumman Aerospace Corporation was awarded a S501.8-million contract under a Foreign Military Sales Programme known as Peace Pearl, sponsored by the USAF's Aeronautical Systems Division. This covered the design of an avionics upgrade for Chinese air force J-8 Ils, to allow the aircraft to fulfil a long-standing requirement for a modern interceptor to police China’s northern border with the USSR.
The avionics package was to consist of a modified Westinghouse AN / APG-66 radar, fire control computer, constant wave illuminator (to allow
the use of SARH missiles like the AIM-7 Sparrow) and back-up equipment. a new HUD , and a Litton LN-39 INS. Under this contract Grumman was to install avionics packages in two J-8 II airframes (due for delivery in March 1989, and now in storage in the USA) for flight test at Edwards AFB later in the year. Development work was to have been completed in February 1991, and de livery of 50 further shipsets was to have been completed by January 1995.
The massacre at Tiananmen Square led to a US government ban on arms exports to China, and there was an immediate halt to work on both projects. Forty Chinese nationals work ing at Bethpage [Grumman] were expelled. Twenty-five Chinese were eventually allowed to return in October 1989, working alongside 180 Grumman employees, and development on the upgrade programme continued. This first phase of the programme was to have involved production o f the modification kits, while the second phase, the initiation of which would have needed a change in US policy.
was to have included flight test and kit delivery.

In April 1990, China pulled out of the Peace Pearl project, informing the US government that it would not proceed with production of the 55 avionics upgrade kits, after some 32 months of work, and when S245- million development phase was almost complete. China's parlous economic situation and US refusal to guarantee the delivery of the upgrade packages have been blamed for the Chinese pull-out

Had a look through Ming-Yen Tsai - From Adversaries to Partners - Chinese and Russian Military Cooperation after the Cold War - but Peace Pearl is only mentioned in passing. However:

Abuot the Author
MING-YEN TSAI is Assistant Professor at the Graduate Institute of International
Politics at National Chung Hsing University in Taiwan. He holds
a Ph.D. in War Studies from King's College London. He is also the executive
editor of the Journal of Strategic and International Studies. A specialist
in Chinese defense modernization, arms transfers, and East Asian international
relations, Tsai has published numerous scholarly articles and policy
reports in both English and Chinese.

Odds are its an article or report you are after, not a book.

Thanks for all of that. I've been through all the journal articles I can find and at this point I am happy enough to have it as a piece of background information that may or may not fit, I'll see how the analysis goes.

Thanks everyone who has contributed and for your help. I have a bit of work to go on this but at least I can call the collection finished now! I'll put a copy up once it's done.
 
One small additional snippet. Jane's Radar and Electronic Warfare Systems 1990-91 states that deliveries of the modified APG-66 radars were to begin in March 1990.
 
Got a fun treat for y'all concerning this topic...

This forward fuselage/nose assembly of a J-8II is hidden away in the Combat Air Museum on Forbes Field ANG base in Topeka, Kansas. If the placard is to be believed, I believe this was intended to be an engineering model of sorts to test installing the new avionics for Peace Pearl.

I took these pictures back in January 2017 on my way back from some Christmas leave and besides being in an old, uninsulated, and VERY FULL hangar (the things I do as an AvGeek), can't provide much more in detail.

EDIT:
Turns out the Museum does have a page on this little treasure, which includes MUCH better pictures than I was able to take, especially those of the cockpit (which I couldn't get to).

Great photos, thank you. The cockpit was a mockup used to figure out where and how to install everything by the sounds. It was a bit of a useless thing to do in the end as every cockpit was different and needed boutique ways of making the avionics fit anyway.
 
NASIC F-8II report

Thanks. He had interesting things to say- I don't agree with a lot of his assumptions and I think some of his thinking was a bit old fashioned. Probably not a surprise considering the periods he lived through.

The Chinese designer's comments about the F-8II's supersonic performance vs the F-16 & Mirage 2000 is something I've read numerous times over the years and I suspect this could be the source of that comment. Fascinating...

What's slightly comical is that the designer critiques the Eurofighter and Rafale as being behind the times but by the time the J-8B/F-8II first flew, they were even farther behind the aviation design power curve.

Yes exactly and this was I mean about outdated thinking; he's also pretty ambitious about those subsonic claims too :D

I think at the end of the day, in that political environment then, it wouldn't have done him many favours to be more honest about the aircraft's shortcomings.
