Origins & Early Life

The Minotaur is a family of United States solid-fuel launch vehicles derived from retired Minuteman and Peacekeeper intercontinental ballistic missiles (ICBM). Built by Northrop Grumman under the U.S. Space Force's Rocket Systems Launch Program, the vehicles are used for orbital and suborbital missions.

Career & Major Achievements

The Minotaur family consists of four primary variants: the Minotaur I, used for launching small satellites into low Earth orbit; the Minotaur II, used primarily as a suborbital target vehicle; the Minotaur IV, a small-lift orbital launch vehicle; and the Minotaur V and Minotaur VI, capable of higher-energy missions including geostationary transfer orbit and trans-lunar trajectories. Minotaur I and II are derived from the LGM-30 Minuteman ICBM, while Minotaur IV, V, VI and the cancelled Minotaur III are based on the LGM-118 Peacekeeper ICBM.

Enduring Legacy & Impact

The Taurus launch vehicle, later renamed Minotaur-C (for "Minotaur-Commercial"), was the first of the Minotaur family and the first ground-launched orbital booster developed by Orbital Sciences Corporation (OSC). It was derived by adding a solid booster stage to the air-launched Pegasus rocket.
