Fly the Chengdu J-10S, the two-seat, tandem version of the Vigorous Dragon designed for training and leading strike missions with the same footprint as the J-10A. With a delta wing, canards, and a top speed approaching Mach 2.1, it combines agility and fine control in high-angle-of-attack maneuvers. The J-10S entered service in 2006, shortly after the two-seat model was certified, featuring an enlarged backbone to accommodate avionics and allow the rear crew member to act as WSO in air-to-ground and air-to-air missions.
