Ursa Major is proud to have made the 2026 Silicon Valley Defense Group’s NatSec100, sponsored by @jpmorgan.

In the last year, we've expanded our production footprint in Colorado and Ohio and flown successfully dozens of times across our solid rocket motors and liquid-powered systems, changing the game in hypersonics and missile defense.

On this Memorial Day, we pause to honor the brave men and women of our nation who gave their lives in service to our country. Their sacrifice is the foundation of the freedoms we hold today.

Ursa Major honors the fallen and stands with the active duty service members, veterans, and families who continue to serve and sacrifice.

Ursa Major’s VP of Strategy, James Swartout, joined Aaron Stein on last week’s Behind the Front podcast from the Foreign Policy Research Institute to discuss the future of defense, from affordable mass and scalable production to the speed required to build, field, and replenish modern capabilities.

“Magazine depth and cost per shot matter more than ever…the future fight will demand affordable mass, scalable production, and the ability to move faster than traditional defense timelines allow.”

"We need to bring in new ways of manufacturing making sure that mission reliability is critical, especially on the hardware side. We need enough capability to move from a just-in-time mentality to a just-in-case mentality." Tune in to #BehindtheFront. https://t.co/hOyATBS2CY

On National Space Day, we celebrate the innovation, industrial strength, and hard engineering work shaping the future of space.

As the space landscape evolves, operational space advantage will come down to resilient systems, reliable partners, and the ability to move quickly without sacrificing quality. That’s the gap Ursa Major is focused on closing.

Built on a foundation of manufacturing heritage, flight-proven engineering rigor, and deep test capability, Ursa Major delivers the operational tempo and domestic propulsion supply chain needed for speed, scale, and reliability in space.

Ursa Major hosted LTG Frank Lozano for a close look at how we’re scaling manufacturing across hypersonics and solid missile systems to meet mission needs.

As demand continues to accelerate, the ability to not just build but scale the technologies of tomorrow is more important than ever. Thank you for visiting Ursa Major, LTG Lozano!

The SkillBridge program creates a seamless bridge between military service and a new professional chapter without losing the deep sense of responsibility and fulfillment that defines a career.

For Wes Adams, retired Air Force Colonel and now Director of Supply Chains & Logistics at Ursa Major, it meant continuing to be given the environment and tools needed to succeed: “My time in the Air Force was rooted in aerospace. Being here continues to fill that passion...Ursa Major has, by every measure, met the requirements and desires SkillBridge sets forth… I found a culture that was deeply satisfying and aligned with my own moral compass and values.”

@ZEISS_Group recently invited Ursa Major’s COO, Justin Siebert, to speak as a keynote at their Quality Excellence Center Grand Opening in North Carolina, where he discussed why quality must come first when building essential capabilities.

Innovators often design first and address scale and qualification later. But when developing critical capabilities that defend lives and keep warfighters out of harm’s way, a quality-first approach must to be built into the core of a company.

Ursa Major understands that true quality in critical capabilities enables delivery at the speed and scale required to meet demand.

Ten flights.
Sustained hypersonic speeds.
100% success rate.
And multiple engines flown, recovered, and flown again.

This what delivering hypersonic capability looks like.

The U.S. space industry is growing fast, but the supply chain is not keeping up.

A new report from the Aerospace Industries Association and PricewaterhouseCoopers highlights mounting pressure across the space industrial base, from component shortages to limited testing capacity and a fragile supplier network.

As Eric Fanning puts it: “The rapid expansion of the U.S. space industry has driven demand to historic highs, placing significant pressure on the supply chain that underpins U.S. leadership in space. Without deliberate steps to strengthen suppliers and modernize regulations, we risk turning today’s momentum into tomorrow’s bottlenecks. A resilient space supply chain is not optional — it’s a national imperative.”

At Ursa Major, we're solving this challenge.

We provide a resilient, domestic propulsion supply chain built for speed, scale, and reliability. Built upon our manufacturing heritage, flight-proven engineering rigor, and deep test capability, we design, develop, and scale chemical propulsion systems for sustained operational tempo.

The future of space depends on the ability to deliver at scale.

Connect with us at Space Symposium this week to learn more!

We’re headed to the 41st Space Symposium next week in Colorado Springs, where innovators and collaborators come together to advance mission-critical capabilities for operational space advantage.

Ursa Major will be on site to discuss how we are scaling to meet growing demand for in-space propulsion. Our space systems deliver a resilient, domestic propulsion supply chain built for speed, scale, and reliability.

Stop by our meeting room to book time with the team.

From the Huntsville Airport to the DC Metro, Ursa Major’s HAVOC Missile System has been front and center at some major transportation hubs recently.

Chris Spagnoletti, CEO of Ursa Major, delivered the industry keynote at the Defense Manufacturing Conference this week in Orlando. His message on deterrence was clear--innovation alone doesn’t win. Deterrence is built through scale on factory floors, on test stands, and in the ability to produce reliable systems at the speed and volume the warfighter requires.

At Ursa Major, we’re focused on delivering both advanced capability, and the industrial base to scale it.

Two recent articles from @PopMech featured Ursa Major's hypersonic advancements after the recent flight of our Affordable Rapid Missile Demonstrator and the announcement of the Ursa Major HAVOC Hypersonic Missile System.

As America’s new class of hypersonic missile, Ursa Major's HAVOC, is “much leaner” than systems in China and Russia’s arsenals and potentially capable of reshaping the hypersonic arms race. Using the Draper engine, described as a “highly adaptable liquid engine system,” HAVOC combines a lighter build with the ability to launch from aircraft, ground systems, and even space.

Its propulsion is a key differentiator, with a liquid rocket engine that “can be throttled to alter its speed in flight,” enabling new approaches to maneuverability and mission execution. As @tomkarako explains, “The ability to throttle this with a liquid engine allows you to do different things…giving you the ability to do different trajectories.”

A smaller, more adaptable system that may ultimately expand what’s possible in hypersonic warfare.

Ursa Major just completed a milestone phase in scaling from propulsion to full-system production. Among other improvements, across our facilities, we’ve advanced our manufacturing capability via:

- Expanded machining capacity driving 200%+ throughput
- Increased additive scale by 10x for rapid, flexible production
- Activated 400-acre SRM test site for qualification at speed
- Added an ISO certified clean room for in-space propulsion systems

“Ursa Major was built to solve one of the hardest problems in defense: delivering high-performance systems at scale and at a price the warfighter can actually use,” said Christopher Spagnoletti, CEO of Ursa Major. “With this phase complete, we’re producing the propulsion, the vehicle systems, and the infrastructure needed to deliver real capability, on timelines that matter.”

Great conversations coming out of the Tectonic Defense Summit this month. Our CEO, Christopher Spagnoletti, joined the “Go Boom” panel to discuss the evolving landscape of missiles and munitions and the urgency to move faster. The focus is clear: scale, adapt, and deliver.

Thanks to everyone who engaged with us in Texas throughout the week. Ursa Major is ready to build on the momentum.
