Title 10 › Subtitle Subtitle A— - General Military Law › Part PART I— - ORGANIZATION AND GENERAL MILITARY POWERS › Chapter CHAPTER 9— - DEFENSE BUDGET MATTERS › § 231
Requires the Secretary of the Navy to send Congress, with the defense budget each year, a detailed plan for building naval ships and a matching plan for keeping and upgrading them, plus official certifications and the Navy leaders’ views. The construction plan must cover two groups of ships—combatant/support ships and auxiliary ships—and show a 30‑year program for each. It must explain the force size and capabilities needed to meet the most recent Presidential national security strategy (or, if that report is not available, the most recent national defense strategy). The plan must show estimated annual funding by ship class (with graphs and tables), total cost per ship, operating and sustainment costs, expected service life for each class and the reason for any change from last year, and a certification of service life by the Senior Technical Authority. For ships scheduled for inactivation in the next five years, the plan must say what will happen to each ship and what warfighting gaps may result. If the last ship of a class is ending in the program, the plan must describe the effect on the shipbuilding industry and, if a replacement program is planned, give a schedule with decision points and contract steps. The Secretary must also include a maintenance and modernization plan that forecasts needs for current and planned ships and describes steps to fund and support shipyards, workforce, and facilities, plus a certification that the budget and future-years plan fund that work. The Congressional Budget Office must report back within 60 days on whether the plan’s funding estimates are sufficient. If the Secretary of Defense omits the plans and certifications, no more than 25 percent of certain emergency operation and maintenance funds may be used until the plans are sent. If the new plan cuts the number of battle force ships versus last year’s plan over the same ten‑year span (the year plus nine more years), the Secretary of Defense must brief Congress within 15 days identifying each ship lost, prior funding for it (including RDT&E, advance procurement, advanced construction, and economic order quantity), and the expected effects on shipyards and major subcontracted parts. Terms: “budget” = President’s annual budget; “defense budget materials” = DoD materials supporting that budget; “national defense strategy” = the four-year defense review; “combatant and support vessel” = commissioned combat ships and ships that support combat (with specified exclusions); “auxiliary vessel” = oceangoing general‑support ships; “expected service life” = years a ship is expected to serve.
