SecondsUnited Launch Alliance (ULA) is a joint venture of Lockheed Martin Space Systems and Boeing Defense, Space & Security. ULA was formed in December 2006 by combining the teams at these companies which provide spacecraft launch services to the government of the United States. ULA launches from both coasts of the US. They launch their Atlas V vehicle from LC-41 in Cape Canaveral and LC-3E at Vandeberg. Their Delta IV launches from LC-37 at Cape Canaveral and LC-6 at Vandenberg.
The Vulcan launch system is a replacement under development by ULA to replace the Atlas-5 and Delta-4 families.
The GEM 63XL, developed by Northrop Grumman, is an extended version of the GEM 63, about 73 inches (185 cm) longer than its predecessor. It is used on the Vulcan rocket. A gimballing variant called the GEM 63XLT was under development for the now cancelled OmegA rocket.
The Blue Engine 4 or BE-4 is being developed for the New Glenn and the Vulcan Centaur rockets.
