All chinese aircrafts are pathetic copies, page 12

i agree. The F-2 is not a copy, but a product of collboration. but its NOT ORIGINAL

HISTORY

The FS-X's origins can be traced back to the early 1980's and the highly secretive Laboratory Three division of Japan's Technical Research and Development Institute (TRDI). There, studies were being carried out to investigate the options for an indigenous design, combining long range with maneuverability, to meet the particular requirements of the Japanese Air Self-Defense Force (JASDF).

It became clear that the pursuit of a completely indigenous design was unrealistic, and help was to be sought abroad. In October of 1987, the Japanese government announced that it was going to develop a derivative version of the F-16C known as the FS-X, to replace the JASDF's Mitsubishi F-1 support fighters, which were to be phased out of active service in the second half of the 1990's.

The program was launched in November 1988 with the signing of a Memorandum of Understanding between the governments of Japan and the United States, and marked the first joint fighter development program between Japan and the United States. The fighter was to be used exclusively by the Japan Air Self Defense Force and therefore development was completely funded by Japan. Primary missions of the new aircraft were be sea lane protection, beach defense and anti-invasion.

The FS-X (Fighter Support Experimental) is being developed by Mitsubishi Heavy Industries as prime contractor with Lockheed Martin Tactical Aircraft Systems, Kawasaki Heavy Industries and Fuji Heavy Industries as principal subcontractors. Development workload has been split approximately 60/40, with the Japanese partners responsible for the larger share.

STRUCTURE & AVEONICS

The FS-X is quite similar in appearance to the F-16, but structural modifications include:

Japanese-designed co-cured composite wing of greater span (1.7m wider) and root chord, with slightly less leading edge sweep. The composites give the wing added strength while reducing the weight;
increased span tailplane;
slightly reshaped and enlarged radome and forward fuselage (fuselage length has increased by 0.5m);
slightly altered Leading-Edge Root Extensions (LERX).

Overall, the FS-X is substantially larger than the F-16, resulting in a maximum take-off weight of 49,000lb, compared to the F-16C's 42,000lb, although both are powered by the same 129kN (29,000lb)-thrust General Electric F110-129 turbofan engine. Other FSX structural-design changes include radar-absorbent material (RAM) applied to the aircraft's nose, wing leading-edges and engine inlet, the use of titanium in the tail and fuselage, the addition of a braking parachute and a two-piece canopy reinforced against large bird strikes.

The primary difference, although less conspicuous than the structural modifications, between the FS-X and the F-16 is in the use of Japanese domestic technology for much of the avionics, including:

a new Mitsubishi Electric (Melco)-designed active phased-array radar comprising 800 3W gallium-arsenide transmit/receive modules;
Yokogawa LCD multi-function display (MFD);
Shimadzu holographic head-up display (HUD);
internal Mitsubishi Electric integrated electronic warfare system;
Japan Aviation Electronics laser inertial-navigation system backed-up with four conventional gyros;

Japan has also been forced to develop its own fly-by-wire software by the US Government's refusal to release the F-16s computer source codes. The FS-X's software is based on MHI's control-configured vehicle (CCV) research program flown in the early 1980's using a modified Mitsubishi T-2 trainer.

Lockheed Martin's participation in the production of the Japan Air Self Defense Force's new F-2 fighter officially began in October 1996, with the award of a $75 million contract from the F-2 prime contractor, Mitsubishi Heavy Industries (MHI). The contract was awarded to Lockheed Martin Tactical Aircraft Systems (LMTAS) of Fort Worth, Texas. LMTAS was the principal U.S. subcontractor during the development phase of the FS-X, and will continue to have major involvement in the production of the aircraft.

"Lockheed Martin has had an outstanding relationship with Mitsubishi Heavy Industries and with the Japan Defense Agency during the development phase of the F-2, and we look forward to continuing that relationship as we enter into production," said Don Jones, the Japan F-2 Program Director at Lockheed Martin Tactical Aircraft Systems. The initial contract award represents the beginning of what should be over $2.5 billion in contracts awarded to Lockheed Martin during the 15-year program.

Lockheed Martin will produce all the aircraft aft fuselages, all the wing leading-edge flaps and 8 of 10 left-hand wing boxes for the FS-X prototypes. The work will be performed at the company's Fort Worth plant, where it is expected to provide about 700 jobs at peak. Lockheed Martin is also providing all of the Stores Management Systems, some of the avionics support equipment and all of the data entry electronics units for the F-2.

Lockheed Martin has received extensive data on Japanese manufacturing processes during the aircraft development phase, as the result of two-way technology transfer agreements. The company will manufacture the F-2 wing boxes from composite materials using unique cocuring methods transferred to the United States by Japanese industry. Transfer of this technology started in 1990 with material testing.
