Minotaur IV+ | TacSat-4
Orbital Sciences Corporation
The Minotaur IV+ launch system is derived from the Peacekeeper ICBM. The first three stages are taken directly from decommissioned Peacekeeper missiles. It is similar to the Minotaur IV, but uses a larger Star-48V upper stage in place of the Orion-38 used on the baseline Minotaur IV.
