United Launch Alliance (ULA) is an American spacecraft launch service provider that manufactures and operates a number of rocket vehicles that are capable of launching spacecraft into orbits around Earth and to other bodies in the solar system. The company, which is a joint venture between Lockheed Martin Space and Boeing Defense, Space & Security, was formed in December 2006. Launch customers of the United States government include the Department of Defense (DoD), the National Aeronautics and Space Administration (NASA), and other organizations.[2]
ULA provides launch services using expendable launch systems Delta IV Heavy and Atlas V, and until 2018 the medium-lift Delta II. The Atlas, Delta IV Heavy and the recently retired Delta IV launch systems have launched payloads including weather, telecommunications, and national security satellites, scientific probes and orbiters. ULA also launches commercial satellites.[3]
اعتبارا من 2020[تحديث], the company is developing the Vulcan Centaur, a successor to the Atlas V that includes some Delta IV technology.[4][5] As of 2019, Vulcan launches were planned to begin in 2021.[6] The Advanced Cryogenic Evolved Stage (ACES) is planned to replace Centaur V on Vulcan from 2023.[7][8]

Company history
Formation and FTC approval
Boeing and Lockheed Martin announced their intent to form a 50-50 joint venture on May 2, 2005, aiming to consolidate the manufacture and development of U.S. government expendable launch vehicles and launch services. The name United Launch Alliance (ULA) was announced at the same time.[9] Annual savings were estimated to be between US$100 million and US$150 million. SpaceX challenged the United States antitrust law legality of the launch services monopoly on October 23, 2005, creating competition with reusable launch systems.[10] The Federal Trade Commission gave ULA anti-trust clearance on October 3, 2006.[11] The commission required ULA to "cooperate on equivalent terms with all providers of government space vehicles ... provide equal consideration and support to all launch service providers when seeking any U.S. government delivery in orbit contract ... and to safeguard competitively sensitive information obtained from other providers of space vehicles and launch services".[12]
