The announcement in March 2008 that Boeing had lost a US$40 billion refuelling aircraft contract to Northrop Grumman and Airbus for the EADS/Northrop Grumman KC-45 with the United States Air Force drew angry protests in the United States Congress.[16] Upon review of Boeing's protest, the Government Accountability Office ruled in favour of Boeing and ordered the USAF to recompete the contract. Later, the entire call for aircraft was rescheduled, then cancelled, with a new call decided upon in March 2010 as a fixed price contract.
Boeing later won the contest against Airbus (Northrop having withdrawn) and US Aerospace/Antonov (disqualified), with a lower price, on February 24, 2011.[17] The price was so low some in the media believe Boeing would take a loss on the deal; they also speculated that the company could perhaps break even with maintenance and spare parts contracts.[18] In July 2011, it was revealed that projected development costs rose $1.4bn and will exceed the $4.9bn contract cap by $300m. For the first $1bn increase (from the award price to the cap), the U.S. government would be responsible for $600m under a 60/40 government/Boeing split. With Boeing being wholly responsible for the additional $300m ceiling breach, Boeing would be responsible for a total of $700m of the additional cost.[19][20][21][clarification needed]
