Quarterhorse Mk 1 flight redefines U.S. aircraft development pace and unlocks next steps toward hypersonic aircraft.

Hermeus has brought online the first phase of a facility that will address the critical shortage of hypersonic test infrastructure in the U.S.

This segment of the flight test campaign was completed in just 21 days and satisfies technical requirements for flight approval.

The former SpaceX, Sierra Space, & Broadcom Chief Information Officer brings decades of deep tech leadership to the rapidly growing Hermeus team.

The new facility advances U.S. capability to more effectively test and field various hypersonic technologies.

The testing marks the first major engine milestone for Hermeus’ supersonic Quarterhorse Mk 2 aircraft.

Designed, built, and integrated in just seven months, Hermeus’ Quarterhorse Mk 1 is the company’s second fully-integrated vehicle in the past year.

As CRO, Mr. Shore will spearhead the maturation of the company’s sales functions while driving growth across all product lines in both defense and commercial markets.

This non-flying prototype acted as a ‘dynamic iron bird’ for the company by validating all major aircraft subsystems in a real-world environment.

Hermeus has been awarded a contract by the Defense Innovation Unit (DIU) to mature hypersonic aircraft subsystem and mission system technology.

Hermeus has accepted its first F100 engine from Pratt & Whitney. Set to be integrated into the enhanced Chimera II turbine-based combined cycle (TBCC) propulsion system, this powerful engine component marks a critical milestone in Hermeus' development of Darkhorse.

Hermeus has demonstrated turbojet to ramjet transition within its engine, Chimera. This is one of the most important technological feats to making operational hypersonic flight a reality.

Raytheon Technologies today announced a strategic investment in Hermeus Corporation through its newly established corporate venture capital group, RTX Ventures.

Hermeus is excited to announce a $100 million Series B funding round led by Sam Altman. New investors Founder's Fund and In-Q-Tel also participated in the round alongside existing investors Khosla Ventures, Canaan Partners, Bling Capital, and Revolution’s Rise of the Rest.

Hermeus is partnering with the Office of the Under Secretary of Defense for Research and Engineering (OUSD R&E), the Air Force Research Laboratory (AFRL), and Pacific Air Forces (PACAF) under a Phase II SBIR contract awarded to provide data and analysis of the various hypersonic aircraft it is developing.
