Hermeus

Kratos Defense will use the Hermeus high-speed Quarterhorse aircraft as part of its support work for the U.S. Navy and Missile Defense Agency’s MACH-TB program.

Hermeus expects to begin installation “within weeks” of a Pratt & Whitney F100-229 engine into its Quarterhorse Mk. 2 supersonic flight demonstrator.

A House panel has endorsed a DARPA plan to fly a reusable hypersonic aircraft demonstrator for reconnaissance and strike missions.

Our roundup of the main aerospace and defense stories making the news this week.

Hermeus has flown its remotely piloted Quarterhorse Mk. 1 demonstrator, marking a key step toward follow-on development of supersonic and hypersonic vehicles.

The Edwards AFB test flight of Quarterhorse Mk.1 marks the first step on a path to follow-on high-speed test aircraft, including autonomous uncrewed products.

Hermeus delivered the vehicle to Edwards AFB on Nov. 16 following the completion of low-speed taxi tests at its Atlanta facility in mid-2024.

The latest tests of the larger-scale pre-cooler are underway at Edwards AFB, California.

Hypersonic aircraft developer Hermeus has unveiled its first flying test vehicle—Quarterhorse Mk. 1—at its Atlanta facility.

The startup details the Quarterhorse flight-test plan as concept design work accelerates for the follow-on Darkhorse hypersonic cruiser.

Under HyCAT, Hermeus says it will use its high-Mach-capable Quarterhorse vehicle to demonstrate key "enabling technologies for operational hypersonic aircraft."

The Quarterhorse Mk 0 is a less than 40-ft.-long mockup featuring the turbine-based combined cycle (TBCC) Chimera 1 engine.

Aircraft startup Hermeus received the first military turbofan that will be integrated into the engine core for the hypersonic Darkhorse uncrewed aerial system.

Hypersonic aircraft developer Hermeus expects to receive Pratt & Whitney’s F100-229 military turbofan for tests later this year.
