Pictures have emerged of the Dragon under development in a propaganda documentary produced by the Communist Party.
Chinese scientists are said to be using a newly constructed wind tunnel to test the Dragon.
US spooks have previously revealed China is developing high-tech nuclear aircraft – which they have codenamed the DF-ZF.
It is believed the aircraft as already been tested seven times.
Images shown in the documentary – broadcast last month – allege to show a mock-up of the spearhead-looking vehicle being tested.
