Type 80 air-to-ship missile

The Type 80 air-to-ship missile, designated ASM-1, is an air-launched anti-ship missile developed by Mitsubishi Heavy Industries, which entered service with the Japan Air Self-Defense Force in 1980. The solid-rocket missile is about 4 metres long and 350 millimetres across, weighs roughly 600 kilograms and flies at about Mach 0.9, with inertial guidance, terminal active radar homing, a range of about 50 kilometres and a 150 kilogram high-explosive warhead. Its main launch platforms are the Mitsubishi F-1 and the P-3 Orion. It was meant chiefly as an air-launched coastal defence weapon, but it can also engage land targets such as buildings and bridges. The design became the basis of the ground-launched SSM-1, the Type 88 surface-to-ship missile, the Type 90 ship-to-ship missile and the Type 91 and Type 93 air-to-ship missiles. The ASM-3 has superseded it without fully replacing it, and the ASM-1 remains in service with the Japan Self-Defense Forces.
