Orbital ATK Set to Launch Minotaur IV Rocket Carrying ORS-5 Satellite for the US Air Force
ORS-5 Launch will be 26th Flight for Minotaur Family of Launch Vehicles

Dulles, Virginia 24 August 2017 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, today announced it is in final preparations to launch the company’s Minotaur IV rocket from Cape Canaveral Air Force Station, Florida, on Friday, August 25, at approximately 11:15 p.m. EDT. The Minotaur IV will carry the U.S. Air Force’s Operationally Responsive Space-5 (ORS-5) spacecraft, which will monitor satellites and space debris to aid the U.S. military’s space situational awareness.

Building on the Minotaur family’s 100 percent success rate, this mission will mark the 26th flight for Orbital ATK’s Minotaur product line and the sixth flight of the Minotaur IV configuration. Minotaur vehicles are based on government-furnished Peacekeeper and Minuteman rocket motors that Orbital ATK has upgraded and integrated with modern avionics and other subsystems to produce an affordable launcher based on reliable, flight-proven hardware. The Minotaur IV is capable of launching payloads up to 4,000 lbs. (or 1,800 kg.) to low-Earth orbit. Minotaur rockets have previously launched from ranges in California, Virginia and Alaska. This will be the company’s first launch of a Minotaur rocket from Launch Complex-46, managed by Space Florida.

“Launching from Cape Canaveral Air Force Station expands the Minotaur launch vehicle’s capability to meet specific mission requirements for our customer,” said Rich Straka, Vice President and General Manager of Orbital ATK’s Launch Vehicles Division. “We are pleased to be able to provide continued launch support for the ORS office with our reliable Minotaur family of launch vehicles and look forward to a successful launch of the ORS-5 mission.”

The Minotaur product line is provided via the Orbital/Suborbital Program (OSP-3) contract and managed by the U.S. Air Force Space and Missile Systems Center (SMC), Launch Enterprise, Experimental Launch and Test Division (LE/LEX), and Rocket Systems Launch Program (RSLP) located at Kirtland Air Force Base, New Mexico.
