Significats de hypersonic glider en anglès

The Pentagon's researchers at Darpa have also been experimenting with hypersonic glider.

Could an armed, hypersonic glider based on the finicky Hypersonic Test Vehicle replace the strike-anywhere nuke-less ICBM?

Most of the experiments center around a new type of warhead for the ballistic missile: a hypersonic glider.

If a standard warhead has an upside-down-U-shaped trajectory, the hypersonic glider's looks like a backwards-L. That's called "boost-glide" in missile jargon.
