KC-X is the name of the United States Air Force program to procure its next-generation aerial refueling tanker aircraft. This aircraft is intended to replace some of the older Boeing KC-135 Stratotankers. The United States Air Force announced on February 29, 2008 that Northrop Grumman and EADS was selected as the company who will build the new tankers with their modified A330 design, to be designated the KC-45A.cite web |url=http://seattletimes.nwsource.com/html/businesstechnology/2004251273_webtankerwin29.html |title=EADS/Northrop trumps Boeing in Air Force tanker competition |accessdate=2008-02-29 |publisher =Seattle Times] This contract is for 179 new tankers and will be worth an estimated US$40 billion.

On June 18, 2008, the U.S. Government Accountability Office sustained a protest by Boeing on the award of the contract to Northrop Grumman and EADS.

The DoD posted a request for proposal on January 30, 2007.cite web |url=http://www.defenselink.mil/Releases/Release.aspx?ReleaseID=10463 |title=Air Force Posts Request for Proposals for Tankers |accessdate=2008-09-08 |accessdate=2007-02-16|publisher = United States Department of Defense ] The U.S. Air Force's main requirements are "fuel offload and range at least as great as the KC-135", airlift capability, ability to take on fuel in flight, and multi-point refueling capability.

Two manufacturers expressed interest in producing this aircraft:

In February 2007, the "Seattle Times" commented on the pre-final designs: "Northrop has been viewed as the underdog, with a heavier, less fuel efficient aircraft. The Airbus tanker would have a maximum fuel capacity of 200,000 pounds. Northrop spokesman Randy Belote said Northrop's K-30 would tack on roughly 20 percent in fuel capacity."cite web |url=http://seattletimes.nwsource.com/html/boeingaerospace/2003569219_tanker13.html|title=Boeing Tweaks 767 for Tanker|first=Donna|last=Borak|publisher=The Seattle Times|date=2007-02-13|accessdate=2008-09-08]

In December 2007 it was announced that this aircraft will be designated the KC-45A regardless of which design wins the competition.

On March 11, 2008, Boeing filed a protest with the Government Accountability Office (GAO) of the award of the contract to the Northrop Grumman/EADS team. Boeing stated that there are certain aspects of the USAF evaluation process that have given it grounds to appeal.

[http://www.defenselink.mil/news/newsarticle.aspx?id=50453 "Pentagon Reopens Bidding on Tanker Contract"] , US DoD, July 9, 2008.] A draft of the revised RFP was provided to the contractors on 6 August 2008 for comments. The revised RFP is to be finalized by mid-August. Proposals are due in October 2008 and selection is planned to be done by the end of the year.

Fulghum | date = 2008-08-11 | publisher = Aviation Week ]

On September 10, Defense Secretary Robert Gates canceled the RFP. "Rather than hand the next Administration an incomplete and possibly contested process, Secretary Gates decided that the best course of action is to provide the next Administration with full flexibility regarding the requirements, evaluation criteria, and the appropriate allocation of defense budget to this mission," a Pentagon release stated.cite web | title = The USAF’s KC-X Aerial Tanker RFP: Canceled | url = http://www.defenseindustrydaily.com/the-usafs-kcx-aerial-tanker-rfp-03009/ | date = 2008-09-110| publisher = Defense Industry Daily ]
