Total shipbuilding costs—which include new construction, refueling of nuclear-powered aircraft carriers, and some other items—would average about $19 billion per year using the Navy’s figures. Total shipbuilding costs would average about $22 billion per year. CBO’s estimates are 11 percent higher than the Navy’s for the first 10 years of the plan, 13 percent higher for the following decade, and 33 percent higher for the final 10 years of the plan.

The Navy’s 30-year plan is built upon the confidence in our estimates during the next five years and the affordability focus placed on our new shipbuilding programs. The Navy acknowledges in the 30-year plan that the accuracy of its estimates decrease in the mid to far term planning periods.
