China's reported hypersonic weapon test raises security concerns

Is China's new hypersonic weapons test a game changer? What does it really mean?

Reports that China may have tested a new hypersonic weapon have grabbed the world's attention and divided national security experts about its strategic significance and whether the U.S. was falling behind in a new arms race.

But it also raised basic questions about the new technology, what it all means, and what it is that China may have tested.

"The U.S. does not currently have the ability to even track this weapon, much less defeat it," said Steve Ganyard, a retired Marine colonel and ABC News contributor.

On Monday, China's foreign ministry denied a Financial Times report that it had tested a nuclear-capable hypersonic missile and instead claimed that it had conducted a "routine test" of a reusable space vehicle.
