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.
