China conducted the third flight test of a new hypersonic missile this week as part of its strategic nuclear program and efforts to develop delivery vehicles capable of defeating U.S. countermeasures, defense officials said.

The flight test of the developmental Wu-14 hypersonic glide vehicle was monitored by U.S. intelligence agencies Tuesday during a flight test in western China.
