Minotaur III rockets consist of four stages; the SR-118 first stage, SR-119 second stage and SR-120 third stage of a decommissioned Peacekeeper missile, with a Super-HAPS fourth stage, derived from the HAPS stage used on Pegasus and Minotaur I rockets. The Minotaur III is capable of launching a 3,000 kilograms (6,600 lb) payload 5,000 kilometres (3,100 mi) downrange on a suborbital trajectory.

Minotaur III launches will be conducted from Vandenberg Air Force Base and the Kodiak Launch Complex.
