A new estimate from the Congressional Budget Office (CBO) projects that a fleet of 15 Trump-class warships would cost approximately $275 billion, highlighting the enormous investment required to field the next generation of naval firepower. The CBO estimates the first Trump-class battleship, designated BBGN, will cost about $23.4 billion to build, while later vessels are expected to average roughly $18 billion each as production becomes more efficient. If approved, the program would dramatically increase Navy spending on surface warships. Annual procurement costs are projected to rise from roughly $6.9 billion to $15.2 billion. Between 2027 and 2056, the Navy plans to acquire 72 major surface combatants, including 15 Trump-class battleships and 57 Arleigh Burke-class destroyers.
