USS Constitution in 1997, formerly (IX-21) from 1941 to 1975The IX (unclassified–miscellaneous) hull classification symbol is used for ships of the United States Navy that do not fit into one of the standard categories.[1] [2] Similar lists of 'miscellaneous' ships can found at
List of auxiliaries of the United States Navy § Miscellaneous ships (AG, T-AG) and
List of yard and district craft of the United States Navy § District auxiliary, miscellaneous (YAG) .Ship status is indicated as either currently active [A] (including ready reserve), inactive [I], or precommissioning [P]. 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; IX ships are generally not ordered as such, but are rather converted from other roles.
Historical overview These vessels usually fall into these categories:
Currently only one ship, USS Prevail (IX-537) , actively carries an IX hull symbol.
