Ursa Major has been awarded a $32.9 million contract to produce 16 advanced Hadley H13 engines for Stratolaunch. The long-term collaboration supports Stratolaunch’s expanding mission schedule and continues the momentum of their successful flight partnership.
The Hadley H13 features mission-specific upgrades that significantly increase engine reusability by allowing more restart cycles, reducing the overall cost per mission, and supporting diverse test and operational profiles.
Hadley engines from Ursa Major have already demonstrated their capabilities in multiple Talon-A flights, achieving sustained speeds over Mach 5 and enabling successful vehicle recoveries, proving the engine’s operational readiness.
