The F-1 is a jet aircraft that featured only in Strikers 1945 III. They only appear as enemies in the Japan random stage.
The Mitsubishi F-1 is Japan's first domestically developed and built supersonic military jet. It was nicknamed "Supersonic Rei-Sen" (Rei-Sen being the Japanese term for Mitsubishi's famed A6M "Zero" fighter of WWII). Mitsubishi Heavy Industries and Fuji Heavy Industries jointly developed the F-1. At first glance, it somewhat resembles the French/Anglo SEPECAT Jaguar, but was a completely independent Japanese effort (although it uses the same engines). Its primary role is anti-ship attack, secondary role is ground attack, and it has limited air-to-air capabilities (short-range AIM-9 Sidewinder for self-defense).
