The first active electronically scanned array (AESA) radar on a combat aircraft was the J/APG-1 introduced on the Mitsubishi F-2 in 1995. The first 76 aircraft entered service by 2008, with a total of 98 airframes produced. Production started in 1996 and the first aircraft entered service in 2000. The basis of the F-2's design is the F-16 Agile Falcon, an unsuccessful offer by General Dynamics to provide a low-cost alternative for the Advanced Tactical Fighter (ATF) competition.
The Mitsubishi F-2 is a multirole fighter derived from the General Dynamics F-16 Fighting Falcon, and manufactured by Mitsubishi Heavy Industries and Lockheed Martin for the Japan Air Self-Defense Force, with a 60/40 split in manufacturing between Japan and the United States.
