USS Gerald Ford carrier - $38 billion
Cost per unit: $12.6 billion
The first in the U.S. Navy's next generation of warships, the vessel is another example of how the Pentagon struggles with buying major weapons systems. Senate Armed Services committee chair John McCain (R-AZ) called the Ford-class carrier program “one of the most spectacular acquisition debacles in recent memory,” noting the first ship is $2.4 billion over its initial price tag. The entire effort is $6 billion over budget.
