PL-21

The PL-21, also written PL-XX, is a Chinese beyond-visual-range air-to-air missile that its reference article describes as still under development. It is guided by active radar homing and is estimated to have a range of 300 to 400 kilometers, powered by a ramjet engine. The article lists the Turkish Gökhan, the American AIM-260 JATM, the European Meteor, the American Long-Range Engagement Weapon and the Russian R-37 as related long-range air-to-air missiles, and also lists the Chinese PL-15 and PL-17. Very little else is established in the cited reference: it names no manufacturer, service entry date or operator, so this entry records only what the source states and leaves those facts open for a later source that states them.
