Template:Launching/Minotaur

The Minotaur IV, also known as Peacekeeper SLV and OSP-2 PK is an American expendable launch system derived from the Peacekeeper missile. It is operated by Orbital Sciences Corporation, and made its maiden flight on 22 April 2010, carrying the HTV-2a Hypersonic Test Vehicle. The first orbital launch is currently scheduled to occur on 8 July 2010, with the SBSS satellite for the United States Air Force.

The Minotaur IV is a four stage vehicle, capable of placing 1,735 kilograms (3,825 lb) of payload into a Low Earth orbit (LEO). It uses the first three stages of the Peacekeeper missile, combined with a new upper stage. On the baseline version, the fourth stage is an Orion-38, however a higher performance variant, designated Minotaur IV+, uses a Star-48V instead. A three stage configuration (no Orion-38), designated the Minotaur IV Lite, is available for Suborbital trajectories. A five stage derivative, the Minotaur V, is also under development.

Minotaur IV launches will be conducted from SLC-8 at Vandenberg Air Force Base, LP-0B at the Mid-Atlantic Regional Spaceport, and Pad 1 of the Kodiak Launch Complex.
