Spaceport America

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 three years — and somehow 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 supersonic. Stay tuned.

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. 📰/ bit.ly/4sFL9f5

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. 👉 Watch here: youtu.be/v5z5Vwug0uY

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 steadily push the limits 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 that was built in less than a week.

Welcome to New Mexico 🚀 We're eager to see the progress and milestones @hermeuscorp will achieve during their time on site!

Mark your calendars for Sunday, Sept. 21, 2025 for our 2025 Open House 🚀 Register/more info | bit.ly/46jzcSx

🚀 Historic. Real. Ready. On May 14 at @Spaceport_NM, Venus Aerospace became the first to fly a high-thrust RDRE. Not theory. Not a sim. A real, breakthrough flight. ✅ More efficient than legacy engines ✅ Radically simple. Scalable. ✅ Built for defense, space & hypersonic flight #RDRE #FlightTest #Hypersonics #NextGenPropulsion

Happy #4thofJuly from the world’s first purpose-built commercial spaceport 🚀

Tune in & take flight with the @AFThunderbirds 🚀 Air Force Elite: Thunderbirds premier tomorrow (5.23.25) on @netflix Viewers will join Astro, Zeke, Primo, Threat, Thunder, & Miami as they train at Spaceport America ✨ Full trailer | bit.ly/3SQ3cPu 📸 | Netflix

A rotating detonation rocket engine just flew—30 seconds of pure proof that pressure gain propulsion works. Huge congrats to @VenusAerospace on this historic first. #Hypersonics #DeepTech #RDRE x.com/VenusAerospace…

"At Spaceport America we have a much larger vision. We're trying to demonstrate that to both our stakeholders and our customers." Our exec. dir. Scott McLaughlin recent shared the vision of our site with @SPACEdotcom 🚀x.com/SPACEdotcom/st…

The first year of our capstone project was a success 🚀 13 students from New Mexico State and New Mexico Tech helped us create real-world launch solutions at our site as part of their senior design projects ✨ 📰 | bit.ly/4j4fyye

Flashing back to last weekend as we took part in the 75th T or C Fiesta 🚀 Personnel from Fiore and Spaceport America joined organizations from throughout the area in Sierra County NM’s largest city for a day of fun! We even got a chance to take part in the parade ✨
