The PL-2 (Chinese: 霹雳-2; pinyin: Pī Lì-2; lit. 'Thunderbolt-2') is an infrared homing (IRH) air-to-air missiles (AAM) developed in the People's Republic of China (PRC). It was a reverse-engineered Soviet Vympel K-13, which in turn was a reverse-engineered American AIM-9B Sidewinder.
The PL-2 was the root of a family of AAMs; of the derivatives, only the PL-5B was successful.
