中国证实进行了高超音速导弹传送器试验

China has conducted an experimental flight of a hypersonic missile delivery vehicle designed to travel several times faster than the speed of sound.

Beijing's Defense Ministry did not comment on the outcome of the test, which it called scientific in nature and not targeted at any particular country.

The Pentagon confirmed, but would not comment on, the Chinese test, which comes as some in the U.S. worry about China's rapid military growth.

If perfected, hypersonic technology could allow countries to strike targets anywhere in the world within minutes, going undetected by missile defense systems.

The test was first reported by the Washington Free Beacon, which quoted U.S. officials who said the vehicle flew at Mach 10, or 10 times the speed of sound.
