DARPA Is Looking for a Way To Shoot Down Hypersonic Weapons

November 14, 2018

The National Interest:

ARPA calls it “counter-hypersonics.” The rest of us would call it a way — or a prayer — to stop nuclear warheads coming down on our heads at 20 times the speed of sound. DARPA, the Pentagon’s pet research agency, wants an interceptor that can stop weapons that are hypersonic (travel faster than Mach 5).

The agency has begun soliciting proposals for Glide Breaker , its project to stop boost-glide vehicles that are lofted high into the atmosphere atop a ballistic missile, and then glide down to Earth. The current exemplar is Russia’s Avangard, touted by President Vladimir Putin as unstoppable by anti-missile defenses. The Avangard is lofted by a giant RS-28 Sarmat ICBM, and then glides down to its target at Mach 20. But China and the U.S. are also developing boost-glide vehicles.

DARPA seeks to “develop and demonstrate a technology that is critical for enabling an advanced interceptor capable of engaging maneuvering hypersonic threats in the upper atmosphere.” And it wants this technology in a hurry: Glide Breaker should be tested in 2020. Meanwhile, the Missile Defense Agency — the Pentagon organization charged with stopping ballistic missiles — also has its program to develop defenses against hypersonic weapons.
