WASHINGTON — The Pentagon is expected to announce today whether the Air Force will rebid a $35 billion contract to build new refueling tankers.

Several lawmakers have been told the agency will decide how to move forward, after a government report found major flaws in the decision to award the lucrative contract to Northrop Grumman and its European partner over Boeing Co.

Two congressional staffers, speaking on condition of anonymity because the decision is pending, said Air Force officials began informing lawmakers Tuesday afternoon of the pending announcement.

Boeing estimates the tanker contract would support 44,000 new and existing jobs with more than 300 U.S. suppliers. The company would perform much of the work in Everett, Wash., and Wichita, Kan.

Northrop said its tanker would support four new factories and 48,000 jobs with 230 U.S. suppliers, including more than 1,500 new positions in Mobile, Ala., where the tanker would be assembled.

Northrop — which currently has 1,228 Utah employees — has said 220 jobs would be added in Utah with the contract, both in Northrop's operations and with four supplier companies. Boeing has 739 employees and 236 suppliers and vendors in Utah.
