AFRL and Ursa Major Showcase Advancements in Liquid Rocket Technology Through Successful Flight Demonstration

The Successful Flight of the Draper Liquid Rocket Engine

In a remarkable demonstration of technological prowess, the Air Force Research Laboratory (AFRL) partnered with Ursa Major on a recent flight of the Affordable Rapid Missile Demonstrator (ARMD) powered by the innovative Draper liquid rocket engine. This flight, conducted on March 12, 2026, not only achieved supersonic speeds but also highlighted critical operational concepts that could redefine the landscape of defense capabilities.

At its core, the ARMD aims to bolster deterrence strategies and provide rapid global strike options. As described by Brigadier General Jason Bartolomei, the commander of AFRL, this venture goes beyond merely developing a single missile. It represents a groundbreaking effort toward establishing a scalable and cost-effective deterrent for national defense. This is a significant shift in the approach to missile technology, emphasizing speed and affordability without compromising advanced features required for modern warfare.

The flight test served as a vital milestone in assessing the technology readiness level of the Draper liquid rocket engine. The ARMD was initially staged for launch using a specialized air log cart, demonstrating the intricate planning involved in military aerospace operations. It underscores the collaboration between public and private sectors, showcasing how the partnership can fast-track the development of next-generation military technologies.

Ursa Major’s leadership echoed this sentiment, stressing the importance of both speed and cost-effectiveness in executing the ARMD program. Chris Spagnoletti, CEO of Ursa Major, emphasized how their efficient process led to a flight-ready missile and propulsion system in just eight months after securing the contract. This rapid progression is indicative of Ursa Major's commitment to innovation and their role in revitalizing the U.S. defense industrial base.

Notably, the flight was grounded in years of work focused on Ursa Major's Hadley liquid rocket engine, reinforcing the company’s position as a leader in aerospace and defense sectors. The collaboration with AFRL exemplifies a successful model for public-private partnerships aimed at advancing rocket propulsion technologies that are both revolutionary and affordable.

Dr. Javier Urzay, the Chief of the Rocket Propulsion Division at AFRL, lauded the ARMD as a pivotal achievement in developing scalable liquid rocket engines essential for future military engagements. This demonstration aligns with the ongoing mission of AFRL, which is to innovate and deliver effective warfighting technologies across air, space, and cyberspace domains.

AFRL continues to be at the forefront of scientific research and development for the Department of the Air Force, exploring diverse technology areas that range from foundational research to advanced technology applications aimed at enhancing national security. As this program progresses, it not only signifies a technological leap but also a strategic shift in how military capabilities can be rapidly evolved to meet emerging threats.
