Here’s some midweek video on China’s version of YouTube showing off the PLAAF’s newest tactical jets. The star of the show is obviously the J-20 stealth fighter. This video cearly shows it performing pre-flight tests of its flight controls, taxiing, taking off and landing. However, as Steve Trimble of The DEW Line points out, the new J-10B makes an appearance in the video powered by China’s own WS10 Taihang engine. This is serious because China views its dependence on Russian-made fighter engines to be a major obstacle to its rise as a military power. The older JF-17 Thunder (which is also flown by Pakistan) also makes several appearances.
