TY-90 (Chinese: 天燕-90; pinyin: Tiān Yàn-90; lit. 'Sky Swallow-90'; NATO reporting name: CH-SA-13) is a Chinese air-to-air missile specifically developed for attack helicopter dogfights. Contrary to erroneous claims, the missile is not developed from MANPADS missiles, but instead, it is specifically designed as an air-to-air missile to engage in helicopter combat.
