PL-8 (missile)
The PL-8 is a Chinese air-to-air missile (AAM) originated from the Israeli Python-3 AAM, (PL short for Pili (Pi Li, 霹雳), meaning thunderbolt). Experience gained from PL-8/Python-3 had helped China greatly in developing its next missile, the PL-9.
China's PLAAF was quite impressed with this missile, and paid for licensed production as the PL-8 AAM in the 1980s. The program was code named "Number 8 Project" (八号工程) and formally started on September 15, 1983. The major supplier of the missile was Xi'an Eastern Machinery Factory (西安东方机械厂) located in Xi'an. From March 1988 to April 1989, technology transfer to China was complete while license assembly and license built parts continued, and by the spring of 1989, the complete domestic Chinese built missile received state certification.
China has also developed a helmet-mounted sight (HMS) system for the PL-8. Elbit Systems DASH (Display And Sight Helmet) helmet mounted sight (HMS). However, it’s not clear that if this was part of the Python-3 deal or a separate deal instead.
