Type-91 Kei-SAM

The Type 91 surface-to-air missile (91式携帯地対空誘導弾, 91-shiki Keitai Chitaikū Yūdōdan) is a Japanese man-portable air-defense system (MANPADS). Its appearance is similar to the US-made FIM-92 Stinger anti-aircraft missile. It was created in order to replace its stock of American-made Stinger MANPADS, since the Type 91 has a better guidance system, which consist of both visible light and infrared system options. The Stinger, on the other hand, uses a passive infrared homing guidance system. In the ranks of the JSDF, the Type 91 is colloquially known as Hand Arrow. The Type 91 is sometimes mistaken as a Japanese-made version of the Stinger. The Type 91 is currently exclusively used by the JSDF and has not been exported overseas to date due to previous interpretations of post-war constitutional restrictions and the laws arising from them.
