Description E'Prime Aerospace has taken the idea of turning swords into plowshares to an entirely new level. A development-stage company, E'Prime Aerospace has employed technology created for the Peacekeeper intercontinental ballistic missile (ICBM) to develop a commercial satellite launch system. The company's Eagle launch vehicles use a modular design based on the Peacekeeper's solid-fuel first stage and incorporate a liquid-fuel upper stage. Once operational, launch vehicles developed by E'Prime Aerospace are expected to handle a variety of commercial satellites.
