In China, showed a modernized aircraft a two-seat fighter-trainer JL-9 developed by the Guizhou Aviation Industry Import/Export Company (GAIEC) for the People’s Liberation Army Air Force (PLAAF) and the People’s Liberation Army Naval Air Force (PLANAF).

The JL-9’s key improvement over its predecessor, the JJ-7, is the redesigned forward fueslage, most notably the replacement of the old inlet cone into a solid nose radome and two lateral air intakes. A new photo emerged August 2011 on Chinese internet websites indicating that the JL-9 has adopted DSI (Diverterless supersonic inlet) design in its latest model, a technology that was previously implemented in the F-35, J-10 and JF-17 fighter jets.
