KC-X was the United States Air Force (USAF) program to procure its next-generation aerial refueling tanker aircraft to replace some of their older Boeing KC-135 Stratotankers. The contest was for a production contract for 179 new tankers with estimated value of US$35 billion. The two contenders to replace the KC-135 aircraft were Boeing and EADS, following the elimination of US Aerospace, Inc. from the bidding process.
The KC-X program followed earlier attempts by the USAF to procure a new tanker. A 2002 plan had the USAF leasing Boeing KC-767 tankers, followed by a 2003 modification where the USAF would buy most of the KC-767 aircraft and lease several more of them. Corruption investigations revealed wrongdoing in the award of the contract and the contract was canceled in 2005, setting the stage for the KC-X program.
