China has developed the world’s most advanced wind tunnel, capable of simulating 30 times the speed of sound and handing Beijing an edge in the race for hypersonic weapons.
The JF-22 facility in Beijing could replicate speeds of up to 23,000mph, far outstripping its rivals in the United States. It is due for completion this year.
Although myself I might wonder whether it’s actually going to work. “Due for completion” and “could” are little signals there.
