AFRL, Ursa Major perform flight demonstration of Draper Liquid Rocket Engine

DENVER — March 12, 2026 — The Air Force Research Laboratory (AFRL) and Ursa Major recently executed a flight of the Affordable Rapid Missile Demonstrator (ARMD) powered by the Draper liquid rocket engine, achieving supersonic speeds and demonstrating concepts of operations. This flight is an innovative step in the advancement of capabilities that strengthen deterrence and provide rapid global strike options.

“This project proves that we can transform and leverage our acquisition models to rapidly deliver critical technology advancements to deter and win in a future conflict,” said AFRL Commander and Air Force Technology Executive Officer Brig. Gen. Jason Bartolomei. “We are not just building a single missile; we are forging a new path toward a cost-effective, mass-producible deterrent for the nation.”

This sentiment is echoed by Ursa Major’s leadership, who emphasized their shared commitment to the speed and cost-effectiveness of the ARMD program. This project represents a new paradigm of acceleration of research and development of critical defense technologies rooted in fast-paced, effective public-private partnerships.
