Summary

The Secretary of Defense must, when preparing the defense budget for a fiscal year, do three things: name every common procurement weapon system in the budget; make all reasonable efforts to keep the procurement unit costs for those systems similar across the services; and show and explain any cost differences in the budget. The Secretary must carry out these duties through the Under Secretary of Defense (Comptroller). Defense budget means the Department of Defense budget in the President’s budget submitted to Congress under section 1105 of title 31. A common procurement weapon system is one for which two or more of the Army, Navy, Air Force, Marine Corps, and Space Force ask for procurement funds.
