Readers are probably familiar with reports that China's 'new' Xian Y-20 transport aircraft (shown below) has just conducted its maiden flight.
The aircraft is clearly very similar in many respects to the Soviet Ilyushin Il-76 transport (shown below), dating back to the 1970s (it uses the same engines as early models of the Il-76, and its claimed performance figures are very close to those of the earlier design). China currently operates about 30 Il-76's, and has more on order.
It's also very similar in some aspects to the Boeing C-17 transport (shown below - note particularly the tailplane and top of the fin, and compare them to the Y-20 above). A Chinese engineer was convicted of espionage in 2009 for, among other crimes, stealing details of the C-17's design.
Here's a video report on the maiden flight of the Y-20.
Yep. That's yet another copycat design. China's current economic and military progress is, to a very large extent, dependent on stealing other countries' designs and systems, and copying them. It doesn't speak well of that country's capability for innovation and original ideas. Nevertheless, the Xian Y-20 is an important element in China's modernization of its military forces, and - when in mass production and service - will offer that country an indigenous strategic airlift capability.
