The PL-10 (PiLi-10) is a semi-active radar-homing medium-range air-to-air missile developed by Shanghai-based 2nd Bureau (now Shanghai Academy of Spaceflight Technology, SAST) in the early 1980s to arm its third-generation indigenous fighter J-8II. The missile was based on the HQ-61 surface-to-air missile developed by the same bureau. The development began in 1980, and the airborne tests of the missile on a H-5 bomber-converted testbed began in 1982. The first fire test from a J-8B fighter took place in 1986. The missile uses a conical scanning semi-active radar-homing seeker, which poor resistance to enemy jamming. The missile received its design certificate in 1986 but did not enter batch production.
