Product Sales and Costs
2025 product sales increased $1.0 billion, or 3 percent, primarily due to higher sales on restricted airborne radar, marine systems and international ground-based radar programs at Mission Systems, higher volume on Sentinel, military ammunition programs and the IBCS program portfolio at Defense Systems, and higher sales on the F-35, TACAMO, E-2, and B-21 programs at Aeronautics Systems. These increases were partially offset by wind-down of work on the restricted space and NGI programs and lower volume on SDA satellite programs at Space Systems.
2025 product costs increased $1.2 billion, or 4 percent, reflecting a lower operating margin rate principally due to the $477 million loss provision recorded on the B-21 program at Aeronautics Systems in the first quarter of 2025, partially offset by higher net EAC adjustments at Defense Systems largely driven by Sentinel.
Service Sales and Costs
2025 service sales decreased $94 million, or 1 percent, primarily due to lower restricted sales at Space Systems and lower service volume at Defense Systems due to the training services divestiture, partially offset by higher restricted sales at Mission Systems and higher volume on aircraft sustainment services at Aeronautics Systems.
2025 service costs decreased $106 million, or 1 percent, consistent with the change in services sales described above.
