Engineered for Mission Assurance.
A pressure-fed LOX/RP-1 engine designed from the ground up with COTS-qualified components, regenerative cooling, and a modular architecture that eliminates single-source risk.
Heritage Performance. Commercial Agility.
The PSGI-1A draws on decades of liquid propulsion heritage while rejecting the cost and schedule penalties of traditional aerospace procurement. Every subsystem was evaluated against a COTS-first criterion: if a commercial component could meet the performance envelope, it was qualified and integrated. The result is an engine with heritage-class Isp and thrust margins, delivered on a commercial timeline.
COTS-First Sourcing
All components evaluated against commercial availability before custom fabrication is considered. 94% of components are COTS-qualified.
Modular Architecture
Subsystems are designed for independent replacement and upgrade. Thrust chamber, injector, and feed system are all field-swappable.
Regenerative Cooling
Propellant-cooled nozzle and chamber wall design eliminates ablative liner replacement between test campaigns.
Restart Capability
Demonstrated multi-start ignition sequence. Engine supports up to 5 restarts per mission profile without hardware replacement.

What Sets PSGI-1A Apart.
Versus heritage component procurement. COTS sourcing strategy drives down recurring unit cost without sacrificing performance margins.
From PDR to first hot-fire. Compressed schedule enabled by COTS availability and modular design that allows parallel subsystem development.
Every component has at least two qualified vendor sources. Supply chain resilience is a design requirement, not an afterthought.
System-level demonstration in a relevant environment. Ready for program integration and qualification testing under government oversight.
