The Type 90 ship-to-ship missile (Japanese: 90式艦対艦誘導弾, SSM-1B) is a ship-launched anti-ship missile developed by Japan's Mitsubishi Heavy Industries. The Type-90 entered service in 1990. It is a naval version of the truck-launched Type 88 (SSM-1) missile, which in turn was developed from the air-launched Type 80 (ASM-1) missile. The Japan Maritime Self-Defense Force bought 384 of the missiles, which were fitted to their Murasame, Takanami, Atago, Akizuki, and Asahi classes of destroyers, as well as Hayabusa-class fast-attack missile boats. With a range of 150 km (81 nmi), high subsonic speed and a 260 kg (570 lb) warhead, the natively-developed Type 90 is similar to the US Harpoon missile Block-1C (RGM-84D) variant which replaced it and first installed on the 9 Murasame-class destroyers that started series production in 1994.
