United Launch Alliance (ULA) is a joint venture of Lockheed Martin and Boeing. 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. U.S. government launch customers include both the Department of Defense and NASA, as well as other organizations.

ULA provides launch services using three expendable launch systemsDelta II, Delta IV and Atlas V. The Atlas and Delta launch system families have been used for more than 50 years to carry a variety of payloads including weather, telecommunications and national security satellites, as well as deep space and interplanetary exploration missions in support of scientific research. ULA has also provided launch services for non-government satellites. (Lockheed Martin retains the rights to market Atlas commercially.[1] Boeing retains similar rights for Delta.)

History[edit]

ULA's headquarters building in Centennial, Colorado

Boeing and Lockheed Martin announced their intent to form the United Launch Alliance joint venture on May 2, 2005.[2] ULA merges the production of the government space launch services of the two companies into one central plant in Decatur, Alabama, and merged all engineering into another central plant in Littleton, Colorado. Boeing Integrated Defense Systems Delta IV and Lockheed Martin Space Systems Atlas V are both launchers developed for the Evolved Expendable Launch Vehicle program intended to provide the United States government with competitively priced, assured access to space.

SpaceX challenged the antitrust legality of the launch services monopoly on October 23, 2005. SpaceX is interested in competing for government launch contracts with the Falcon 9 rocket. On January 7, 2006 the Department of Defense gave preliminary approval to the United Launch Alliance.[citation needed]

In September 2006, the Pentagon renewed their support for ULA, and announced their support to the Federal Trade Commission (FTC).[citation needed] The FTC gave their anti-trust clearance on October 3, 2006.[3] The joint venture began operations on December 1, 2006.[citation needed]

In November 2010, United Launch Alliance was selected by NASA for consideration for potential contract awards for heavy lift launch vehicle system concepts, and propulsion technologies.[4]

Facilities[edit]

ULA program management, engineering, test and mission support functions are headquartered in Centennial, Colorado. Manufacturing, assembly and integration operations are located in two buildings, one at Decatur, Alabama, and the other in Harlingen, Texas. [5]

ULA launches from both coasts of the United States, depending on the customer's desired orbit. East coast Atlas V launches take place from Launch Complex 41 while east coast Delta IV launches take place from Launch Complex 37. Both are located in Cape Canaveral, Florida. West coast launches take place from Vandenberg Air Force Base in southern California.

The first launch conducted by ULA was of a Delta II, from Vandenberg Air Force Base on December 14, 2006.[6] The rocket carried the USA 193 satellite for the National Reconnaissance Office. This satellite failed shortly after launch and was intentionally destroyed on February 21, 2008 by an SM-3 missile fired from the Ticonderoga class cruiser USS Lake Erie.[7]

On June 15, 2007, the engine in the Centaur upper stage of a ULA-launched Atlas V shut down early, leaving its payload – a pair of NRO L-30 ocean surveillance satellites – in a lower than intended orbit.[8] The anomaly caused delays to forthcoming Atlas V and Delta IV launches, due to the common RL-10 upper stage engines. The fault was traced to a new type of valve being used in place of an older component which had gone out of production. To resolve the problem, the older design was put back into production, and in the meantime, surplus valves from the original production run were used.

Commercial and international launches aboard Atlas V and Delta rockets are managed by Lockheed Martin Commercial Launch Services and Boeing Launch Services, respectively.
