Chimera LEO

Chimera LEO is Epic Aerospace’s orbital transfer vehicle line built to give satellites freedom of movement in low Earth orbit after launch. Rideshare and dedicated launches often drop payloads into a compromise orbit; Chimera LEO delivers spacecraft to their intended operational orbit and can perform ongoing repositioning throughout a mission’s life.

The vehicle is built around Epic Aerospace’s in-house, vertically integrated systems: a non-toxic hypergolic main propulsion system, aluminum alloy primary and secondary structures, and proprietary subsystem avionics for main engine and reaction control system (RCS) control. Epic also manufactures its own 95-98% concentrated hydrogen peroxide propellant used in its hypergolic propulsion architecture.

Chimera LEO is capable of apogee kicks of roughly ±450 km and local time of ascending node (LTAN) changes of about 3 hours in under 90 days, allowing satellite operators to correct insertion errors, adjust orbital planes, or reposition constellations without requiring a dedicated launch. The design philosophy behind the vehicle, described by Epic as “advanced simplicity,” emphasizes a streamlined, manufacturable architecture that leverages the company’s own propulsion, structures, and avionics stack rather than relying on third-party subsystems.
