The ASM-3 is a supersonic anti-ship missile being developed by Mitsubishi Heavy Industries to replace the ASM-1 and ASM-2 missiles. The major launch platform is the Mitsubishi F-2. Planned Initial Operational Capability was 2016. The missile will be used by the Japan Air Self-Defense Force. It can attack not only ships, but also ground targets. Since the original model of ASM-3 had a short range of 200 km, it was not deployed immediately, and an improved model was developed from 2017 to 2020, and deployment of ASM-3A with a range of about 300~400 km started in 2021. In the future, it may also have a range of 400 km or more.
