Future class of United States Navy destroyer. First of three advanced technology surface combat ships, to be followed by the CG(X) cruiser and the Littoral Combat Ship. Advanced capabilities carriers, of the CVNX type, are also in the offing. The DD(X) was originally known as the DD-21.

The DD(X) features a low radar profile and an integrated power system, which can send electricity to power the electric drive motors or weapons systems, which, in the future, may include rail guns. The DD(X) should also reduce the needed number of crew and lower lifecycle operating costs, while providing a flexible platform.
