A new air-to-air missile (PL-10) has been seen on Chinese J-11B fighters. The PL-10 looks very similar to the South African A-Darter. This is an 89 kg (196 pound), three meter (9.3 foot) long heat seeking missiles that is highly maneuverable and resistant to countermeasures. The A-Darter is not yet in service, but is designed to be similar to the U.S. AIM-9X. A-Darter is being developed in cooperation with Brazil. It’s not known if PL-10 is actually in service. It has been described and discussed for at least three years.
The J-11 is a clone of the Russian Su-27. The J-11A is being supplanted by the J-11B. At least two squadrons of J-11Bs are in service with the air
There appear to be about 200 J-11s in service, with about 40 percent of them J-11Bs. This is deduced by the number of cell phone photos showing up, from different air force and navy air bases.
