Typhon is Orbital Operations’ high-performance propulsion architecture, designed to deliver the speed, precision, and endurance required to power every maneuver for the next generation of orbital missions.

Designed for reuse.

Engineered for efficiency.

Typhon combines proven liquid hydrogen and liquid oxygen propulsion with a dual turbo-expander architecture optimized for repeated operation in orbit.


By eliminating the need for consumable helium buffer gas, the system supports true vehicle reusability while delivering the performance required for rapid orbital maneuvering.

Working together with Boreas, Typhon transforms launch heritage propulsion into a reusable orbital propulsion system.

High Thrust:
10,000 lbf on both Defender and Flagship. Both vehicles use the same engine, with Flagship featuring larger propellant tanks. Enables rapid repositioning in orbit.

High ISP:
Designed for rapid transfers between LEO, GEO, and beyond, enabling high-thrust orbital maneuvering across multiple mission profiles.

Engine Architecture:
Hydrogen and oxygen dual turbo-expander cycle, high efficiency, repeated operations without consumable helium systems.

Future Missions:
Built to support evolving mission requirements through modular payloads and partner-developed capabilities.

Typhon delivers the performance needed to maneuver across orbital regimes with speed and precision. From rapid repositioning to long-range transfers, the platform provides the delta-v required to support responsive operations throughout cislunar space.
