The US Air Force is expected to issue requests for proposals around July for a new fleet of in-flight refuelling aircraft, say military and industry sources close to the programme. The development will follow the release of an analysis of alternatives mandated by US Congress after the collapse last year of the air force's attempted acquisition of 100 Boeing KC-767 tankers.

"We have been told to do an analysis of alternatives and we have been told that there will be a competition," says USAF chief of staff Gen John Jumper. "When we have a chance to assess what its recommendations are we will address this with our leadership and with the Congress and be ready to go as quickly as we can."

Boeing says it will again offer the 767 or any other aircraft that will fit the service's criteria, hinting at the possible promotion of its developmental 787. EADS North America is promoting the Airbus A330-200 multirole tanker transport already selected by Australia and the UK.
