Raytheon, NEC, Hazeltine, and Kokusai Electric. The fire control radar, IRS, the mission computer, and the EW system were developed by Japan. In addition, the flight control computer, the flight control laws and related computer software were essentially all developed and integrated by Japan. Final assembly was done in Japan, by MHI at its Komaki-South facility in Nagoya. Larger wings give an aircraft better payload and maneuverability in proportion to its thrust, but also tend to add weight to the airframe in various ways. More weight can have negative effects on acceleration, climbing, payload, and range. To make the larger wings lighter, the skin, spars, ribs and cap of the wings were made from graphite-epoxy composite and co-cured in an autoclave. This was the first application of co-cured technology to a production tactical fighter. This technology for the wings encountered some teething problems, but proved to be a leading-edge use of a technology that provides weight savings, improved range, and some stealth benefits. This technology was then transferred back to America, as part of the program's industrial partnership. The F-2 has three display screens, including a liquid crystal display from Yokogawa. Mitsubishi used the existing F-16 design as a reference guide for design work, and more than 95% of F-16 engineering drawings are changed for F-2. Some differences in the F-2 from the F-16A: a 25% larger wing area composite materials used to reduce overall weight and radar signature longer and wider nose to accommodate a J/APG-1/J/APG-2 active electronically scanned array (AESA) radar. Almost simultaneously with a single squadron of USAF F-15C Eagles, the F-2 was the first operational military aircraft in the world to feature an AESA radar, before the F-22 Raptor’s AN/APG-77 AESA radar. larger tailplane larger air intake three-piece cockpit canopy Equipments and OFP related to the avionics system differ from the F-16 in many aspects. Original flight control system. capabilities for four ASM-1 or ASM-2 anti-ship missiles, four AAMs, and additional fuel tanks Also, the F-2 is equipped with a drogue parachute, like the version of the F-16 used by South Korea, the Netherlands, Norway, Greece, Turkey, Indonesia, Taiwan, and Venezuela. Operational history On 7 February 2013, two Russian Air Force Sukhoi Su-27 fighters briefly entered Japanese airspace off Rishiri Island near Hokkaido, flying south over the Sea of Japan before turning back to the north. Four F-2 fighters were scrambled to visually confirm the Russian
