Increased Inventory Goals for Battle Force Ships

The average annual cost of buying the ships and unmanned systems under the plan would be about $34 billion (in 2021 dollars), CBO estimates, $2 billion more than under the previous plan. In this report, the Congressional Budget Office analyzes that shipbuilding plan and compares it with the Navy’s fiscal year (FY) 2020 shipbuilding plan, which was submitted to the Congress in March 2019. Rather than submitting such a report with the Navy’s 2021 budget, on December 9, 2020, the Department of Defense submitted a 30-year shipbuilding plan to the Congress that covers the years 2022 to 2051. The force of unmanned systems would rise from just a few prototypes today to about 140 by 2045.Įach year, as directed by the Congress, the Navy submits an annual report with the President’s budget describing the planned inventory, purchases, deliveries, and retirements of the ships in its fleet for the next 30 years. If the Navy adhered to the schedule for purchases and ship retirements outlined in its December 2020 plan, the inventory of manned ships would rise from about 300 today to about 400 by 2038. The Navy also plans to purchase 223 unmanned undersea and surface vehicles to supplement its fleet. The Navy plans to purchase 404 new ships between 20-300 combat ships and 104 logistics and support ships. The Navy’s total budget would increase from about $200 billion today to $279 billion (in 2021 dollars) by 2051. Annual operation and support costs for the fleet would grow from $74 billion today to $113 billion by 2051. CBO estimates that total shipbuilding costs, including costs for nuclear refueling and unmanned systems, would average about $34 billion per year (in 2021 dollars), 10 percent more than the Navy estimates. The December 2020 plan would require average annual shipbuilding appropriations almost 50 percent larger than the average over the past five years. In this report, the Congressional Budget Office analyzes that shipbuilding plan and estimates the costs of implementing it. The Navy did not submit its 30-year shipbuilding plan with the fiscal year 2021 budget, but the Department of Defense submitted a plan to the Congress on December 9, 2020, that covers the period 2022 to 2051.
