Well its expected since Mitsubishi does posess the know-how and never really abandoned the practice of developing planes for the Japanese Defense Industry even after WWII.

"In the defense sector, MHI has produced jet fighters for the Japan Air Self-Defense Force and anti-submarine helicopters for the Japan Maritime Self-Defense Force, as well as aero-engines, missiles and torpedoes. It produced North American F-86 Sabre, Lockheed F-104 Starfighter and McDonnell Douglas F-4 Phantom II fighters. It manufactured 139 Mitsubishi F-15J fighter aircraft from 1981 and produced 200 Sikorsky S-70 family Mitsubishi H-60 helicopters from 1989, in both cases under license production. The company also plays an important role in the Japanese Ballistic Missile Defense System program."
