Washington is concerned about hypersonic missile technology and its potential military applications by China and Russia, a U.S. arms control official said on Monday, after a media report that Beijing had tested a nuclear-capable hypersonic glide weapon, APA reports quoting Reuters.
Hypersonic weapons are usually defined as missiles that fly more than five times the speed of sound, and a race is under way for the next generation of long-range weapons that are harder to detect and intercept.
The Financial Times, quoting five people familiar with the matter, said at the weekend that China had tested a weapon in August that flew through space and circled the globe before cruising down towards a target which it missed.
The Chinese foreign ministry denied the report. It said it had carried out a routine test in July, but added: "It was not a missile, it was a space vehicle."
