Quarterhorse

Unmanned (remote-controlled) hypersonic aircraft demonstrator. Powered by a modified Pratt & Whitney F100 engine under partnership with RTX. Hermeus has flown an F-16-sized demonstrator and is targeting supersonic flight; a third aircraft is in development. Aims for Mach 5 capability.

Quarterhorse is at the prototype stage: it exists, but DEPLOY has no verified real-world deployment on record. Manufacturer capability claims should be read as claims pending independent verification.

Quarterhorse is made by Hermeus, based in Atlanta, GA, USA, founded in 2018.

Quarterhorse is at prototype stage and is not yet available for sale.
