Northrop swings to loss on B-21 headwinds
Northrop Grumman on Thursday said it swung to a loss in the fourth quarter from a year-earlier profit as it took a $1.17 billion charge related to the U.S. Air Force's next-generation B-21 stealth bomber. The B-21 started flight tests during the fourth quarter, after which the U.S. Air Force awarded Northrop a low-rate initial production (LRIP) contract for the bomber on a fixed-price basis. "We believe it is probable each of the first five LRIP lots will be performed at a loss," Northrop said.
