CAPE CANAVERAL AFS, Fla. –-- A United Launch Alliance (ULA) Delta IV rocket carrying the second Global Positioning System III (GPS III) satellite, designated Magellan, for the U.S. Air Force Space and Missile Systems Center lifted off from Space Launch Complex-37 on August 22 at 9:06 EDT.
This mission marked the 29th and final flight of the Delta IV Medium rocket and the 73rd GPS launch by a ULA or heritage vehicle.
“Thank you to the team and our mission partners for the tremendous teamwork as we processed and launched this critical asset, providing advanced capabilities for warfighters, civil users, and humankind across the globe,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “We are proud of the strong legacy of the Delta IV Medium program, and look forward to the future with our purpose-built Vulcan Centaur.”
The GPS III system, built by Lockheed Martin, represents the next step in modernization of the worldwide navigation network with a new generation of advanced satellites offering improved accuracy, better anti-jam resiliency and a new signal for civil users.
This mission launched aboard a Delta IV Medium+ (4,2) configuration vehicle, which included a 4-meter Payload Fairing and two Northrop Grumman solid rocket motors. The common booster core for Delta IV was powered by the RS-68A engine, and the Delta Cryogenic Second Stage was powered by the RL10B-2 engine, both supplied by Aerojet Rocketdyne.
ULA’s next launch is Boeing’s CST-100 Starliner, Orbital Flight Test, aboard an Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla.
ULA maintains a track record of 100% mission success with 135 successful launches.
With more than a century of combined heritage, ULA is the world’s most experienced and reliable launch service provider. ULA has successfully delivered more than 130 satellites to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system, and support life-saving technology.
