About
Centurion is a fuel-rich staged-combustion rocket engine burning liquid oxygen and liquid natural gas (LOX/methane), developed by Rocket Propulsion Systems as a low-cost, highly reusable propulsion building block. Priced around $150,000 per unit, Centurion is rated for up to 50 reuse cycles, dramatically reducing the cost per flight compared to expendable engines of similar thrust class. Its compact envelope and modular design let it be clustered into multi-engine boost stages or used singly for in-space and upper-stage applications, forming the common propulsion core across RPS’s small launch vehicle, suborbital vehicle, hypersonic booster, and orbital transfer vehicle product lines.
