Minotaur IV & V

The OSP-2 Minotaur IV SLV combines elements of government-furnished decommissioned Peacekeeper boosters with technologies from our proven Pegasus®, Taurus® and OSP Minotaur launch vehicles. The vehicle consists of three Peacekeeper solid rocket stages, a commercial Orion 38 fourth stage motor and subsystems derived from our 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 IV vehicle to launch U.S. government-funded satellites into low-Earth orbit.

The Minotaur IV SLV incorporates a standard 92-inch fairing from our Taurus booster and supports dedicated or shared launch missions. Capable of boosting payloads more than 1,750 kg into orbit, the vehicle is compatible with multiple U.S. government and commercial launch sites. The Minotaur IV is designed to provide 18-month mission response including payload integration and launch by Orbital's experienced launch crews.

The first Minotaur IV is currently under construction to launch the U.S. Air Force's Space-Based Surveillance System (SBSS) satellite in December 2008.
