PL-2
The PL-2 (Chinese: 霹雳-2; pinyin: Pī Lì-2; lit. 'Thunderbolt-2') is a short-range, infrared-homing air-to-air missile developed by China as its first domestically produced heat-seeking weapon, designed primarily for rear-aspect engagements against fighter aircraft and medium bombers.[1] It features a length of approximately 2.9 meters, a diameter of 0.127 meters, a launch weight of 85 kilograms, a maximum range of 7-8 kilometers, and a top speed of Mach 2.2, with a fragmentation warhead containing around 1,000 fragments for enhanced lethality.[1][2] Development of the PL-2 began in the early 1960s under the auspices of the Chinese aviation industry, drawing on reverse-engineered designs from a captured U.S. AIM-9B Sidewinder missile obtained in 1958 and Soviet technical assistance provided in 1961, which led to its basis on the Soviet Vympel K-13 (NATO: AA-2 Atoll).[1][2] The missile underwent initial testing in 1968, but progress was hampered by the Cultural Revolution; it achieved operational status in the late 1970s, with mass production authorized in 1972 and approximately 2,950 units delivered by 1983.[2] Its guidance system relies on passive infrared homing using a lead sulfide photodetector with a 3.5-degree detection angle, requiring target acquisition prior to launch and offering limited resistance to countermeasures like flares.[1][3] The PL-2 was initially integrated into Chinese J-6 (MiG-19 variant) and J-7 (MiG-21 variant) fighters, marking a significant step in China's indigenous missile capabilities during the Cold War era.[1] It saw its first reported combat attempt in 1982 during a Sino-Vietnamese border clash, where a launch against a Vietnamese MiG-21 failed, though unconfirmed reports suggest possible earlier use by Pakistani F-6 exports in the 1971 Indo-Pakistani War.[1][2] Variants include the PL-2A (late 1970s), which improved the seeker for better anti-jamming, and the PL-2B (certified 1981), featuring a larger warhead, enhanced fuse reliability, and extended range to about 10 kilometers by incorporating elements from the AIM-9E Sidewinder.[1][2] While largely superseded by advanced successors like the PL-5 and PL-10 in modern Chinese aircraft, the PL-2 remains in limited service on trainer variants such as the JJ-7 and has influenced export models compatible with Western systems.[1][3]Overview
Description
The PL-2 is a family of short-range, infrared-homing air-to-air missiles developed by China through reverse engineering of the Soviet K-13 (NATO: AA-2 Atoll), initially provided to China in 1961 as part of a technology-sharing agreement between the two nations. This acquisition stemmed from the 1958 Taiwan Strait Crisis, during which China recovered an intact American AIM-9B Sidewinder missile from a downed aircraft, subsequently sharing it with the Soviets who adapted it into the K-13 design before reciprocating with technical data and samples. The PL-2 was specifically adapted for integration with Chinese fighters such as the J-6 (a licensed MiG-19 variant) and J-7 (a licensed MiG-21 variant), filling a longstanding void in the People's Liberation Army Air Force's (PLAAF) arsenal for close-range aerial combat.[2][1] Entering service in the 1970s, the PL-2 became China's first domestically produced short-range air-to-air missile, providing the PLAAF with an indigenous short-range air-to-air capability at a time when geopolitical tensions limited access to foreign armaments. Its development marked a pivotal achievement in Chinese military aviation, transitioning from reliance on imported systems to self-sufficient production and thereby enhancing tactical flexibility in dogfight scenarios.[1] The PL-2 family began with a basic passive infrared seeker but evolved through subsequent variants that refined seeker sensitivity, motor performance, and overall reliability, establishing a foundational lineage for the broader PL-series of air-to-air missiles. This progression culminated in successors like the PL-5, which incorporated all-aspect homing and extended range, underscoring the PL-2's enduring influence on China's missile technology advancements. Approximately 2.9 meters in length and with a range of up to 10 kilometers in later iterations, the PL-2 exemplified early efforts toward precision-guided weaponry in Chinese service.[4]Specifications
