VIDEO: Taihang-equipped J-10B! Also starring: J-20 and JF-17

We bring you the latest video to surface from the world's least-secured runway for officially classified, experimental military jets. (Pssst: Hey, AVIC! Seriously, it's like you're not even trying now. It was almost more fun when you tried to keep this stuff hidden. Geez, when did China become the world's most transparent military about new weapons technology?)

This video first shows take-offs by the J-20, the JF-17, and, making a surprise debut, a runway appearance by the all-new J-10B powered by the indigenous WS10 Taihang engine (see the 5-minute mark). Taihang may soon replace the Russian-made AL31 in the PLAAF fleet and, like the J-20 airframe, symbolizes China's ambition to become independent of foreign supply chains for its own tactical aircraft.

To understand the differences between the J-10A and J-10B, read our colleague Greg Waldron's write-up on their different features on Asian Skies.
