Minotaur-3 (OSP-2 Peacekeeper TLV)

Minotaur-3 [OSC]

The Minotaur III suborbital launch vehicle provides the ability to deliver payloads up to 3000 kg on long range, suborbital trajectories for various U.S. Government-sponsored applications. It utilizes residual Peacekeeper solid rocket motors combined with Orbital's commercial launch vehicle technologies. The Minotaur III is designed to be adaptable to a variety of potential payloads. A mono-propellant hydrazine propulsion fourth stage called Super-HAPS provides precision trajectory control to support the high-accuracy delivery of target or reentry systems for technology demonstration. Multiple adapters and separation systems enable a variety of options for payloads.

The combination of thoroughly proven motors and Orbital's extensively flight proven commercial subsystems results in a uniquely reliable, cost-effective solution. All vehicles in the Minotaur family have common avionics architectures, software, ground support equipment, and processes, providing the benefits of a shared heritage and continuity across multiple vehicles.
