New fighter jet appears ready for PLA

China's air force will soon commission the J-10B fighter jet, the most advanced military aircraft the country has ever developed on its own, information released by military observers show.

Several pictures showing 14 of the planes lined up outside an unidentified aircraft factory have been circulating on military websites. Experts said their gray paint scheme indicates that they will soon be delivered to the People's Liberation Army air force.
