The world's most dangerous long-range air-to-air missile

China's PL-XX long-range air-to-air missile

The PL-XX long-range air-to-air missile mentioned here by the US media The anti-air missile should be what we often call the PL-21 long-range air-to-air missile. US media believe that the PL-XX long-range air-to-air missile has entered service together with the PL-15 medium-range air-to-air missile and the PL-10 short-range air-to-air missile in 2015, becoming the backbone of the Chinese Air Force.

Unlike air-to-air missiles such as the PL-15, which tend to attack fighter-sized targets, the main targets of the PL-XX long-range air-to-air missile are enemy bombers, tankers, transport aircraft and airborne early warning aircraft. Large high value targets. In wartime situations, the Chinese Air Force will use PL-XX long-range air-to-air missiles to first eliminate targets such as U.S. and Japanese airborne early warning aircraft and aerial tankers, weakening or even directly disintegrating the U.S. and Japanese air systemized combat capabilities. Then use other air-to-air missiles to deal with US and Japanese fighter jets.

The first reason why the US media rated PL-XX as the most threatening air target is that it has the longest range, reaching 500 kilometers. It is currently the longest-range air-to-air missile in the world. . The second reason is that this air-to-air missile uses dual-mode guidance. In addition to being equipped with a large-diameter active phased array radar seeker, it is also equipped with an infrared seeker as a backup. In this way, even if it encounters strong electromagnetic interference, it can still effectively hit the target.

Although there are currently many air-to-air missiles using active phased array radar seekers, their radar diameters are too small compared to those of the PL-XX, and the T/R they carry There are fewer components, so the overall performance is not as good as the PL-XX long-range air-to-air missile.

Of course, the PL-XX long-range air-to-air missile also has weaknesses, that is, its size and weight are relatively large. Fighters such as the J-10C cannot carry it, and the built-in magazine of the J-20 stealth fighter cannot fit in it. It can only be carried externally by heavy-duty fighters such as the J-16 and J-11BG, and can only carry a maximum of 2 at a time.
