List of hull classifications

Last updated

The list of hull classifications comprises an alphabetical list of the hull classification symbols used by the United States Navy to identify the type of a ship.

Contents

The combination of symbol and hull number identify a modern Navy ship uniquely. A heavily modified or repurposed ship may receive a new symbol, and either retain the hull number or receive a new one. Also, the system of symbols has changed a number of times since it was introduced in 1907, so ships' symbols sometimes change without anything being done to the physical ship.

Many of the symbols listed here are not presently in use. The Naval Vessel Register maintains an online database of U.S. Navy ships.

The 1975 ship reclassification of cruisers, frigates, and ocean escorts brought U.S. Navy classifications into line with other nations' classifications, and eliminated the perceived "cruiser gap" with the Soviet Navy.

If a ship's hull classification symbol has "T-" preceding it, that symbolizes that it is a ship of the Military Sealift Command, with a primarily civilian crew.
