Anybody on our forums who is interested to talk about the "Japanese Viper"?

Latest related LM press release:

LOCKHEED MARTIN RECEIVES $150 MILLION CONTRACT FOR F-2 COMPONENT WORK

FORT WORTH, Texas, April 2, 2007 --

Lockheed Martin [NYSE: LMT] received a contract from Mitsubishi Heavy Industries (MHI) on March 31 valued at $150 million to manufacture components for five additional F-2 production aircraft. MHI is the prime contractor for the F-2, Japan’s operational support fighter.

"Japan selected the Lockheed Martin F-16 multi-role fighter in 1987 as the basis for the joint Japan-U.S. design of a new support fighter for the Japan Air Self Defense Force (JASDF), and Lockheed Martin began delivery of production airframe and avionics components and other F-2 systems to MHI in 1998. We continue to deliver quality products that meet their needs and those of the JASDF," said Jim Shidler, Lockheed Martin F-2 program director. "We have also begun support of MHI as they and the JASDF consider and incorporate specific new systems and weapons onto the F-2 to enhance its operational flexibility and capability."

The Japan Government recently authorized the total production of 94 F-2 aircraft, and this new award to Lockheed Martin brings the total aircraft under contract to 86. Lockheed Martin is producing components for 81 F-2 aircraft from those orders initiated under the 10 previous annual contracts. Under this new contract, the company will provide all of the aft fuselages, wing leading-edge flaps and stores management systems; 80 percent of all left-hand wing boxes; and other avionics and avionics support equipment. Lockheed Martin components are shipped to MHI’s Komaki-South facility in Nagoya, Japan, where they are assembled with other components by MHI to form the F-2. MHI delivered the first production aircraft to the Ministry of Defense in September 2000, and has delivered 71 aircraft to date.

Lockheed Martin successfully completed all component deliveries in January 2007 for its ninth annual production contract with MHI. Delivery of major components for the tenth contract, signed last year, began in December 2006. This year’s contract, the eleventh, is effective immediately with deliveries scheduled to begin in February 2008. Lockheed Martin has delivered more than 370 major airframe, avionics and avionics support equipment components in this successful partnership with MHI since production deliveries began.

Headquartered in Bethesda, Md., Lockheed Martin employs about 140,000 people worldwide and is principally engaged in the research, design, development, manufacture integration and sustainment of advanced technology systems, products and services. The corporation reported 2006 sales of over $39.6 billion.

I was lucky enough to be assigned to the F-2 program in 1998 during the flight test program at Gifu AB, outside of Nagoya, Japan. Our Lockheed flight test support team consisted of a team leader, and engineers from avionics, flight control, and structures (me). I had not been involved in design or manufacturing, so it was a good opportunity to learn about the airplane. The Japanese team was very hospitible, but we were not given much to do. Later, I returned to the base as the the only Lockheed engineer there and was much more directly involved in the flight test.

The Gifu AB flight test facility was first class and for the most part, the engineers were also. All in all, not much different from testing at Edwards, except Eddy has better weather and clearer air space.

From an engineering standpoint, the airplane had some development problems, just like all other advanced airplanes. That is why we test - find the problems and fix them.

Many thanks for your first reply to this new topic, johnwill! Very nice that you are an F-2 program professional! Would you tell us some further details? Anybody of our F-16.net users who has already an F-2 Aircraft Database "on hand" (including serial and tail numbers)?

How was the wing cracking situation remedied? I hope it was not just by reducing the maximum Gs the aircraft could pull.

Sorry I can't supply any late information, as I left the program in May 2001. Not sure what wing cracking you are referring to, FDiron. There were no cracking problems while I was on the program, but there were some composite bonding problems. As you probably know, the wing is a co-cured composite structure, where the spars, ribs, and lower skin are all bonded together. One of the advantages of this type of construction is the elimination of fastener holes in the lower skin. Lower skin fastener holes are a potential source of cracks due to repeated loads. Ground structural tests showed the need to develop better bonding methods in certain areas and that was done. Of course, composite structure does not normally crack, it delaminates.

Reducing g-limits is not normally a response to cracking problems. Flight test involves measuring structural loads all over the airplane and comparing with design loads. If measured loads are significantly larger than design loads, then sometimes maneuver limits are reduced until the structures can be improved. Airplanes already built can be strengthened, and redesign applied to new airplanes.

If cracks appear, crack growth is monitored, and sometimes growth can be stopped by grinding out the crack or drilling small holes at the crack tip. Reducing maneuver limits does not really help much with cracking, since cracks will continue to grow with repeated low magnitude loads.

The proper unofficial nickname is "Viper-Zero".

As you may know, the usual suspects for data such as all F-2 serial numbers, are

Interestingly enough (to me anyway) we flight tested the F-2 at Gifu AB, the same base where the A6M Zero was tested almost 70 years ago. They still have a Zero there, although it had not been restored the last time I was there, 2001. I seem to remember that my friend in the JASDF told me it had been raised from the ocean and would never be restored.
