In a post on BNET Industries, Matthew Potter notes that the Department of Defense is willing to go ahead with only Boeing bidding on the KC-X:
The Secretary of Defense Robert Gates in testimony to the House Armed Services Committee made it clear that the Defense Department and U.S. Air Force will release the Request for Proposal (RFP) for the new KC-X tanker and award a contract even if only Boeing (BA) submits a proposal. The Department hopes that the Northrop Grumman (NOC) and EADS (EADS:P) will submit a bid but will go forward with the planned contract even if they don’t.
In early December Northrop Grumman’s CEO sent a letter to the Air Force stating that due to the terms of the draft RFP they felt that it so favored Boeing that they and their partner EADS, parent of Airbus, would not submit a proposal. Northrop had won the contract in 2008 only to lose it on protest by Boeing with the Government Accountability Office (GAO) saying that the Air Force changed the requirements and was not completely fair to Boeing. An earlier attempt to award Boeing a lease for KC-767 aircraft collapsed amid scandals and Congressional desire to have contest.
