The Pentagon's next big project is hypersonic scramjet cruise missiles able to evade enemy interceptors

DARPA wants hypersonic missiles capable of surviving increasingly sophisticated enemy air defenses The new program seeks major gains in range, speed, and survivability Russia's Zircon gives Washington an existing hypersonic cruise missile benchmark The Pentagon is pursuing a new hypersonic cruise missile concept designed to survive increasingly capable enemy air defense networks.

The Defense Advanced Research Projects Agency (DARPA) Next Generation Hypersonic Cruise Missile (NGHCM) program wants contractors to design a hypersonic scramjet cruise missile capable of evading enemy interceptors.

The effort comes as U.S. forces intercept Iranian retaliations from its attack, increasing concerns about existing stand-off weapons facing sophisticated defenses.

DARPA seeks a survivable hypersonic cruise missile DARPA says advanced integrated air defense systems could increasingly restrict American forces and weaken existing stand-off strike capabilities.

Its request for information seeks concepts capable of achieving significant improvements in range, cruise speed, altitude, or other operational characteristics.

The agency specifically wants a demonstrator that could establish the basis for producing future missiles in substantially larger quantities.

The proposed system would use scramjet propulsion, allowing atmospheric air to support combustion during sustained high-speed flight.

DARPA has not specified a precise velocity requirement, although hypersonic flight generally refers to speeds exceeding Mach 5.

The request instead emphasizes broader performance, survivability, affordability, and development speed rather than prescribing one fixed technical configuration.

“Future U.S. military operations face increasingly significant challenges from the rapid proliferation and advancement of highly capable Integrated Air Defense Systems,” DARPA said.

The agency also asks companies to consider how payload, range, speed, altitude, maneuverability, signatures, and launch-platform capacity could influence overall effectiveness.

Potential launch arrangements include tactical fighters, heavy bombers, surface-based vertical launch systems, and larger ground-based platforms.

DARPA also encourages participation from emerging tech companies and contractors outside the traditional defense industry.

Testing and rapid development are major priorities DARPA is seeking a development schedule capable of moving important technical milestones toward flight testing faster than conventional acquisition programs.
