Three vehicles, each one larger and more capable than the last.

Mk 0 proved the design-build-test approach, Mk 1 flew, and Mk 2.1 expands the flight envelope even further.

When we talk about iterative development, we actually mean it. We’ve already made three iterations in ow our team moves even faster with each build.

ICYMI: Quarterhorse Mk 2.1 is airborne.

Nine months after flying our last aircraft, we already built and flew another — proving how fast this team can build, test, and fly high-speed aircraft.

The work has just begun. With first flight complete, the campaign continues toward

Stakes in ground: Dec. 2025
1st flight: Feb. 2026

@hermeuscorp wanted to move fast. We were able to move fast with them to build a site suitable for their unique op 🚀

We're proud to have witnessed the first flight of Quarterhorse Mk 2.1 on 2.27.26.

Live from New Mexico...it’s the Hermeus Podcast: Spaceport Edition.

Our CEO and President sit down outside the hangar with a few members of the broader Quarterhorse team to talk through the road to first flight for Quarterhorse 2.1.

Meet Quarterhorse Mk 2.1: an F-16-sized jet built to break the sound barrier.

It’s the first of three jets in the Mk 2 lineup. Instead of waiting years between tests, we build and fly them in rapid succession. Real data from one flight feeds directly into the next, letting us s of speed and performance.

Mk 2.1 will fly supersonic. Mk 2.2 will go even faster. Subsequent phases like 2.3 will continue to push toward Hermeus’ end goal of unlocking sustained ramjet-powered flight and delivering operational hypersonic capability for the United States — this decade.

Step by step, this is how Hermeus builds the world’s fastest aircraft.

Quarterhorse Mk 2.1 is coming alive.

✔ F100 full thrust firing
✔ Multiple drop tests
✔ Ground vibration testing
✔ Verification of vehicle-ground systems

Fast on the ground and faster in the air.

Proud to sponsor Aviation & Aerospace Day at the Senate. @Spaceport_NM in my district has supported 985 jobs and generated $122 million in new money for New Mexico. From Spaceport to the Roswell Air Shows, our state is proving the sky is just the beginning. ✈️🚀

At NM Aviation & Aerospace Day Reception, @Spaceport_NM CEO Scott Mclaughlin shared highlights from the 2025 annual report and @LtGovMorales reaffirmed NM commitment to Aerospace and Aviation. Proud to see NM's momentum across innovation, education and industry @AerospaceStates

We celebrated NM Aviation & Aerospace Day in the Capitol this week, recognizing a top industry driving innovation & econ growth in New Mexico. Grateful to sponsors @LockheedMartin, @virgingalactic, @Deploy_Hub, @RocketLab, @CaribouThunder, Red Arrow Flight Academy & more. #nmleg

We're not just building the planes fast, we're building the infrastructure fast.

Our team has stood up deployed operations at @Spaceport_NM, transforming a blank slate into a disciplined flight-test complex, including a 6,000-square-foot custom hangar for Quarterhorse Mk 2.1 than a week.
