Gen. Arthur Lichte, who runs Air Mobility Command, told reporters that either aircraft offered by The Boeing Co. or Northrop Grumman Corp. were capable of the mission, but urged a quick decision to avoid further strain on the service’s already aging aircraft.

“I don’t care which tanker wins,” said Lichte. “I just need a new tanker.”

The four-star general said if the program is delayed by another year or more, the Air Force will be forced to fly some its current fleet past 2040, which would make those planes at least 80 years old.

A Pentagon spokesman could not immediately be reached for comment Wednesday afternoon.

The aircraft are used to refuel combat and other support planes in flight and have helped widen the range of the U.S. military’s reach. The planes have been used in operations in the Persian Gulf, the Balkans and Afghanistan.

Boeing in February lost the deal to replace 179 aerial refueling tankers to Northrop Grumman and its partner Airbus parent European Aeronautic Defense and Space Co. Chicago-based Boeing filed a protest in March.

The competition was reopened after government auditors found “significant errors” in the Air Force’s decision. The revamped contest – overseen by Pentagon acquisition chief John Young – is focused on eight areas where the Government Accountability Office found problems.

The Pentagon was expected to release its final request for bids last week, already late for a self-imposed deadline of Aug. 15 that continues to slip.

Under the Pentagon’s current plan, both Boeing and Northrop Grumman were expected to respond to the bids request by Oct. 1, with a final contract award by the end of the year. But both of those deadlines also are likely to be missed.

Boeing has threatened to exit the competition if it does not get an additional four months from the Pentagon to assemble its offer.
