About
The Vacuum / In-Space Propulsion Module packages a single Centurion engine, optimized with a larger expansion ratio for vacuum operation, as an upper-stage and orbital transfer vehicle (OTV) propulsion unit. It is intended for missions requiring efficient in-space maneuvering after a rideshare or dedicated launch to low Earth orbit, leveraging the same reusable LOX/methane Centurion architecture used across RPS’s launch vehicle and hypersonic product lines.
