The People's Liberation Army Air Force uses a modified version of the Russian-made Su-30, the Su-30MKK variant. These were introduced in December of 2000, and so far 134 have been built.
The Su-30MKK variant is, in fact, manufactured in China by the Chinese Shenyang Aircraft Company.
The MKK has a crew of two and a wingspan of nearly 50 feet. They're equipped with both air-to-air and air-to-surface missiles, as well as unguided rockets and laser-guided bombs.
