Minotaur-4-Lite (HTV-2a) [OSC]
The most recent addition to Orbital's line of space launch vehicles, the Minotaur-4 (a.k.a. OSP-2 Peacekeeper SLV) combines elements of government-furnished decommissioned Peacekeeper missiles with technologies from our proven Pegasus, Taurus and OSP Minotaur boosters. The vehicle consists of three Peacekeeper solid rocket stages, a commercial Orion-38 or a Star-48V fourth stage motor and subsystems derived from established space launch boosters. Under a 10-year contract with the U.S. Air Force Space and Missile Systems Center, Orbital will develop and operate the low-cost Minotaur-4 vehicle to launch U.S. government-funded satellites into low-Earth orbit.
The Minotaur-4-Lite suborbital launch vehicle incorporates a standard 92-inch fairing from the Taurus booster. The fourth stage is ommited.
