Boeing’s defense unit reported $139 million in total losses on three of its key fixed-price development programs in the last quarter of 2023, the company reported Wednesday.

The firm confirmed to Defense News on Thursday that the losses were on the KC-46A Pegasus refueling tanker, the T-7A Red Hawk jet trainer and the MQ-25 Stingray refueling drone. Boeing declined to say how much each program lost, noting the amounts were small enough that the company did not have to publicly report them.
