The Trump administration's plan to add the largest battleships since World War II to the U.S. Navy's fleet has a price tag of $275 billion, according to estimates from the Congressional Budget Office. 

The report also notes that U.S. shipyard may not have enough capacity to complete the orders. 

Each of the 15 nuclear-powered ships will cost more than $18 billion, which puts them in the range of the Navy's Ford-class super carriers. The carriers have been to date the most expensive naval vessels ever built, CNN reported. 

The battleships, which have been called "Trump-class," are a large part of the Navy's total procurement budget for surface combatants, which will increase from $11 billion in 2025 to $18 billion in 2027, according to the CBO. The procurement includes frigates and destroyers. 

The Trump administration announced the plan to build the battleships last December. President Donald Trump said that they would be fitted with “guns and missiles at the highest level,” hypersonic weapons, electric rail guns, cruise missiles and the “most sophisticated lasers in the world.”
