What is the difference between Navy and MARAD ships?
The Navy has the responsibility for the disposal of obsolete warships (e.g., aircraft carriers, battleships, cruisers, destroyers, frigates, and submarines) whereas MARAD has the responsibility for the disposal of obsolete merchant type vessels that are part of the National Defense Reserve Fleet (NDRF). The NDRF includes some former Navy amphibious and auxiliary type ships that had been title transferred to MARAD. The Navy intends to only make conventionally-powered warships available for use as artificial reefs.
