Griffin said Thursday at a National Defense Industrial Association-sponsored event in Washington that DoD considers developing boost-glide, air-breathing hypersonic platforms.
He noted that the U.S. needs to come up with space-based sensors and other new systems designed to counter hostile hypersonics in their long-cruise phase.
âWe canât separate hypersonics defense from the space layer,â Griffin added.
Deputy Defense Secretary Patrick Shanahan joined Griffin at the Hypersonics Senior Executive Series event.
