Hermeus scales DIU high-Mach flight contract ceiling to $219M
Hermeus said an expanded Defense Innovation Unit contract raised the programme ceiling to $219 million for high-Mach flight and high-speed payload-release demonstrations.

Evidence notes
- The expanded scope covers work with the U.S. Air Force and U.S. Navy.
- The programme aims to demonstrate uncrewed aircraft reaching high-Mach speeds and releasing payloads in flight.
- The disclosed figure is a contract ceiling, not a statement that the full amount has been obligated or recognised as revenue.
Company context
Hermeus develops high-speed unmanned aircraft for U.S. and allied defense missions, using rapid flight-test iterations across its Quarterhorse and Darkhorse programmes. Its April 2026 Series C package combined $200M of equity with $150M of debt and valued the company at $1B; the aircraft are remotely controlled rather than autonomous.
