'''United Launch Alliance, LLC''' ('''ULA''') is an American [[launch service provider]] formed in December 2006 as a joint venture between [[Lockheed Martin Space]] and [[Boeing Defense, Space & Security]]. The company designs, assembles, sells and launches rockets, but the company subcontracts out the production of [[rocket engine]]s and [[solid rocket booster]]s.

When founded, the company inherited the [[Atlas (rocket family)|Atlas rocket family]] from Lockheed Martin and the [[Delta (rocket family)|Delta rocket family]] from Boeing. As of 2024, the Delta family has been retired and the Atlas V is in the process of being retired. ULA began development of the [[Vulcan Centaur]] in 2014 as replacement for both the Atlas and Delta rocket families. The Vulcan Centaur completed its maiden flight in January 2024.

The primary customers of ULA are the [[United States Department of Defense|Department of Defense]] (DoD) and [[NASA]], but it also serves commercial clients.

== Company history ==
=== Formation ===
Boeing and Lockheed Martin announced on 2 May 2005 that they would establish a 50/50 [[joint venture]], United Launch Alliance (ULA), to consolidate their space launch operations.<ref name="ula2005">{{cite web |date=2 May 2005 |title=Boeing, Lockheed Martin to Form Launch Services Joint Venture |url=https://www.ulalaunch.com/all_news_items/2005/05/02/boeing-lockheed-martin-to-form-launch-services-joint-venture |url-status=live |archive-url=https://web.archive.org/web/20190417111551/https://www.ulalaunch.com/all_news_items/2005/05/02/boeing-lockheed-martin-to-form-launch-services-joint-venture |archive-date=17 April 2019 |access-date=17 April 2019 |website=United Launch Alliance}}</ref>

The two companies had long competed for launch services contracts from the DoD, and their Atlas and Delta rockets were the two launch vehicles selected under the [[Evolved Expendable Launch Vehicle]] (EELV) program. The DoD had hoped the program would foster the creation of a strong, competitive commercial launch market. However, both companies said that this competition had made space launches unprofitable.<ref name=":1" /> Boeing's future in the program was also threatened in 2003 when it was found to be in possession of proprietary documents from Lockheed Martin.<ref name="CRS-Report" /><ref>{{cite news |last=Bowermaster |first=David |date=January 9, 2005 |title=Boeing probe intensifies over secret Lockheed papers |url=http://old.seattletimes.com/html/businesstechnology/2002146025_boeinglockheed09.html |url-status=dead |archive-url=https://web.archive.org/web/20170312103157/http://old.seattletimes.com/html/businesstechnology/2002146025_boeinglockheed09.html |archive-date=2017-03-12 |access-date=2020-05-07 |newspaper=[[Seattle Times]]}}</ref> To end [[Lawsuit|litigation]] and competition, both companies agreed to form the ULA joint venture.

SpaceX attempted to challenge the merger on anti-trust grounds, saying it would create a space launch monopoly.<ref>{{cite web |last=Morris |first=David Z. |date=2017-06-17 |title=Is SpaceX Undercutting the Competition Even More Than Anyone Thought? |url=http://fortune.com/2017/06/17/spacex-launch-cost-competition/ |url-status=live |archive-url=https://web.archive.org/web/20190125075021/http://fortune.com/2017/06/17/spacex-launch-cost-competition/ |archive-date=25 January 2019 |access-date=17 April 2020 |website=[[Fortune (magazine)|Fortune]]}}</ref> The [[Federal Trade Commission]] ultimately granted ULA anti-trust clearance, prioritizing national security access to space over potential competition concerns.<ref>{{cite web |date=October 3, 2006 |title=FTC gives clearance to United Launch Alliance |url=https://www.spaceflightnow.com/news/n0610/03ulaftc/ |website=Spaceflight Now}}</ref><ref>{{cite book |title=Mergers and Acquisitions: Understanding the Antitrust Issues |date=2008 |publisher=[[American Bar Association|ABA]] Section of Antitrust Law |isbn=978-1-60442-046-3 |edition=3rd |location=Chicago, Illinois |oclc=213864774}}</ref>

=== Michael Gass era (2005–2014) ===
Michael Gass was announced as the first CEO of ULA and oversaw the merger of the two groups. Production was consolidated into one central plant in [[Decatur, Alabama]] while all engineering was moved into a facility in [[Littleton, Colorado]].<ref name="sn20180124">{{cite web |url=http://spacenews.com/to-stay-competitive-in-the-launch-business-ula-courts-commercial-customers/ |title=To stay competitive in the launch business, ULA courts commercial customers |last1=Erwin |first1=Sandra |last2=Henry |first2=Caleb |date=24 January 2018 |website=SpaceNews |access-date=2018-06-25}}</ref> The parent companies retained responsibility for marketing and sales of the Delta and Atlas rockets.

Cost pressures led ULA to announce it would lay off 350 of its 4,200 workers in early 2009,<ref name="dbj20081114">{{cite news |date=2008-11-14 |title=United Launch Alliance plans layoffs |url=http://www.bizjournals.com/denver/stories/2008/11/10/daily45.html |access-date=2014-11-16 |newspaper=[[Denver Business Journal]]}}</ref><ref name="dbj20090805">{{cite news |last=Avery |first=Greg |date=2009-08-05 |title=ULA seeks land for a combined HQ |url=http://www.bizjournals.com/denver/stories/2009/08/10/story2.html |access-date=2014-11-16 |newspaper=Denver Business Journal}}</ref> and decommissioned two of its seven [[launch pad]]s.<ref name="Berger 2017" /><ref name="nsf20140702">{{cite web |last=Graham |first=William |date=2 July 2014 |title=ULA Delta II successfully lofts OCO-2 to orbit |url=http://www.nasaspaceflight.com/2014/07/delta-ii-oco-2-launch-vandenberg/ |access-date=22 February 2015 |website=NASA Spaceflight}}</ref> ULA also joined and later left the [[Commercial Spaceflight Federation]] during this period.<ref>{{cite web |date=2014-05-13 |title=Membership |url=http://www.commercialspaceflight.org/membership/ |url-status=dead |archive-url=https://web.archive.org/web/20140513024623/http://www.commercialspaceflight.org/membership/ |archive-date=2014-05-13 |access-date=2020-05-07 |website=Commercial Spaceflight Federation}}</ref><ref>{{cite web |last=Johnson |first=Alexandra |date=June 21, 2010 |title=United Launch Alliance Joins the Commercial Spaceflight Federation |url=http://www.commercialspaceflight.org/2010/06/united-launch-alliance-joins-the-commercial-spaceflight-federation/ |access-date=2020-05-07 |website=Commercial Spaceflight Federation}}</ref>

The introduction of lower-cost competition and rising ULA launch costs attracted scrutiny. ULA's reliance on government funding for launch readiness, including maintaining multiple launchpads and rocket variants, became a point of discussion, particularly as the EELV program experienced a [[Nunn–McCurdy Amendment|cost breach]] in 2012.<ref name="CRS-Report">{{cite web |url=https://www.everycrsreport.com/files/20160513_R44498_ed5b90543df15e81aa4fff1a56c5b8cc911a9889.pdf |title=National Security Space Launch at a Crossroads |date=May 13, 2016 |website=[[Congressional Research Service]] |access-date=August 5, 2020}}</ref>

ULA was awarded a DoD contract in December 2013 to provide 36 rocket cores for up to 28 launches. The award drew protest from [[SpaceX]], which said the cost of ULA's launches were approximately US$460 million each and proposed a price of US$90 million to provide similar launches.<ref>{{cite web |last=Leopold |first=George |date=April 28, 2014 |title=SpaceX launches protest of Air Force rocket contract |url=http://defensesystems.com/articles/2014/04/28/spacex-protest-air-force-ula-contract.aspx |url-status=dead |archive-url=https://web.archive.org/web/20141006103216/http://defensesystems.com/articles/2014/04/28/spacex-protest-air-force-ula-contract.aspx |archive-date=6 October 2014 |access-date=3 October 2014 |website=Defense Systems}}</ref> In response, Gass said ULA's average launch price was US$225 million, with future launches as low as US$100 million.<ref>{{cite web |last=Gurss |first=Mike |date=May 20, 2014 |title=Responding to Critics, ULA Discloses Pricing Information |url=http://www.spacenews.com/article/military-space/40637responding-to-critics-ula-discloses-pricing-information |url-status=dead |archive-url=https://archive.today/20140523182322/http://www.spacenews.com/article/military-space/40637responding-to-critics-ula-discloses-pricing-information |archive-date=23 May 2014 |website=SpaceNews}}</ref>

ULA is investigating a way to [[Reusable launch vehicle|partially reuse]] its launch vehicles with the Sensible Modular Autonomous Return Technology (SMART) system. This system envisions jettisoning the BE-4 engines and [[avionics]] as a single unit which would be protected by an inflatable heat shield during its descent back to Earth. After being slowed by parachutes and splashing down in the ocean, the heat shield would double as a raft, and the engines and avionics module would be retrieved for refurbishment.
