Epic Aerospace

Epic Aerospace was founded in 2019, backed by Y Combinator, to build a network of orbital transfer vehicles (OTVs), or "space tugs," that give satellites the freedom to move in space after they separate from their launch vehicle. The company is vertically integrated, designing and manufacturing its own hypergolic propulsion systems (including a 900N main engine), structures, and avionics in-house, and even producing its own 95-98% concentrated hydrogen peroxide propellant.

Epic's design philosophy of "advanced simplicity" underpins its Chimera family of vehicles, which spans two product lines: Chimera LEO, for low Earth orbit maneuvers such as apogee kicks and local time of ascending node (LTAN) changes, and Chimera GEO, for full GTO-to-GEO insertion of payloads up to 2,000 kg in under a month, as well as hosted-payload station-keeping, end-of-life services, and cislunar trans-lunar injection for CAPSTONE-class lunar missions.

The company's first demonstrator, Chimera LEO 1, launched aboard SpaceX's Transporter-6 rideshare mission, validating Epic's in-house propulsion, structure, and avionics stack in orbit. Building on that flight heritage, Epic Aerospace is working toward what it describes as the first dedicated space-transportation network, expanding its OTV services from LEO satellite repositioning to GEO insertion and eventually cislunar transport.
