Type 80 Air-to-Ship Missile (80式空対艦誘導弾, ASM-1) is an Air-to-ship missile developed in Japan. The missile is primarily intended as an air-launched coastal defence weapon. In fact it is somewhat more capable than this, able to engage both sea and land targets such as buildings and bridges. The Type 80 also serves as the basis of several other weapons; it forms part of the ground-launched SSM-1 system and was also developed into the Type 88 SSM(Surface-to-Ship Missile), the Type 90 SSM (Ship-to-Ship Missile), and the 91 and 93 ASMs (Air-to-Ship Missile).
