PL-9
air-to-air missile

The PL-9 (Chinese: 霹雳-9; pinyin: Pī Lì-9; lit. 'Thunderbolt-9') is a short-range, infrared-homing air-to-air missile (AAM) developed by the People's Republic of China. The missile was developed by integrating the PL-5 and PL-7 airframes with the PL-8's targeting seeker. It was later succeeded by the PL-10.
History
The PL-9 program was initiated in 1986. The missile entered batch production in 1989. Two improved variants, PL-9B and PL-9C, was certified in 1992 and 2002. The latest version of the PL-9 is PL-9D.
The missile was originally designed by Dong Bingyin (董秉印) at the Luoyang Electro Optical Center, which is also known as Institute 612 and renamed in 2002 as the China Air-to-Air Guided Missile Research Institute (中国空空导弹研究院). After Dong Bingyin died, his position was succeeded by Mr. Jin Xianzhong (金先仲).
Begin with the source’s own compact description: “PL-9” is air-to-air missile. The dossier treats that line as a proposition to test through PL-9, air-to-air and missile, not as a finished interpretation.
Why this record matters
The phrase “air-to-air missile” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 17, 2026. The linked authority identifier is Q859138. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1986, 1989, 1992 and 2002.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
