List Of Yard And District Craft Of The United States Navy

This is a list of yard and district craft of the United States Navy. It covers the various types of craft and ships that support the bases and harbors of the United States Navy. The hull classification symbols for these craft begin with (Y).

Ship status is indicated as either currently active (including ready reserve), inactive or precommissioning Ships in the inactive category include only ships in the inactive reserve, ships which have been disposed from US service have no listed status. Ships in the precommissioning category include ships under construction or on order.

Historical overview

This list demonstrates that the US Navy constantly recycles and repurposes its small craft for new roles. Some craft on this list have had as many as six such conversions in their history. Some of these conversions have been surprising from an environmental viewpoint, such as the conversion of fuel oil barges into water barges. Some conversions have been surprising from an economic viewpoint, such as the simultaneous conversions of open barges to covered barges during the conversions of covered barges to open barges, which can be justified only by relatively high transportation costs.

The District Auxiliary, Miscellaneous (YAG) designation has been used as a cover for at least two ships employed in classified tests of biological, chemical, and nuclear weapons (aka WMD).

Some of these vessels have held prior or later classifications as unclassified miscellaneous (IX), or more rarely as auxiliaries miscellaneous (AG, T-AG).
