Sources say Northrop Grumman (NOC -0.1%) will not bid against Boeing (BA -1.1%) in the much-contested ~$50B U.S. Air Force aerial tanker contract after concluding a bid "would be too risky." Northrop and partner EADS won the last bidding war in Feb. 2008, but the decision was scrapped following a government audit. An announcement could come after the close.
