I’m no expert on Chinese defence, or on the trustworthiness of the various websites that cover Chinese defence, but there is an interesting analysis on two possible new Chinese air-to-air missiles by Richard Fisher at the International Assessment and Strategy Center, which describes itself as a think-tank on security issues.
China’s AIM-9X-class short-range AAM? (from wforum.com)
The two missiles are the short-range, infrared-guided PL-ASR, or PL-10, which resembles South Africa’s Denel R-Darter, and the PL-13, a ramjet-powered derivative of the medium-range, active-radar PL-12. The PL-13 (or is it PL-21?) looks roughly equivalent to Europe’s MBDA Meteor.
If their existence is confirmed, these missiles – like the Chengdu J-10 and Shenyang J-11B fighters they will arm – look pretty competent. Check out Chinese Military Aviation and decide for yourself.
