PL-4

The PL-4 (Chinese: 霹雳-4; pinyin: Pī Lì-4; lit. 'Thunderbolt-4') was an air-to-air missile (AAM) developed by the People's Republic of China. It was designed by the 612 Research Institute and the Zhuzhou Aeroengine factory. The first version, the PL-4A, was China's first semi-active radar homing (SARH) AAM. It was developed into the infrared homing PL-4B.
