Powering the future of defense and aerospace
Advanced propulsion systems across space, hypersonics, and national security domains
The Mission
Optimized for speed, cost, and reliability
Ursa Major provides propulsion for critical missions across the commercial and government sectors.
The Problem
Propulsion is an existential bottleneck
For the United States and its allies, national security and space industry growth depend on access to reliable propulsion. But right now, demand is outpacing supply.
9x
orbital launch growth rate in the last two years
54%
of all launch failures were caused by propulsion issues in the last 15 years.
