Industrial capability would have to be rebuilt. The half-trillion-dollar figure is doubted, with a qualification that the eventual cost depends on future inflation.

Building the proposed battleship would require recreating industrial capability. The suggestion of half a trillion dollars per ship is doubtful, although the eventual figure would depend on inflation before construction. No alternative estimate is supplied.
