U.S. NAVY SHIPS -- Listed by Hull Number
The U.S. Navy's system of alpha-numeric ship designators, and its associated hull numbers, have been for several decades a unique method of categorizing ships of all types: combatants, auxiliaries and district craft. Though considerably changed in detail and expanded over the years, this system remains essentially the same as when formally implemented in 1920. It is a very useful tool for organizing and keeping track of naval vessels, and also provides the basis for the identification numbers painted on the bows (and frequently the sterns) of most U.S. Navy ships.
The ship designator and hull number system's roots extend back to the late 1880s, when ship type serial numbers were assigned to most of the new-construction warships of the emerging "Steel Navy". During the course of the next thirty years, these same numbers were combined with filing codes used by the Navy's clerks to create an informal version of the system that was put in place in 1920. Limited usage of ship numbers goes back even earlier, most notably to the "Jeffersonian Gunboats" of the early 1800s and the "Tinclad" river gunboats of the Civil War Mississippi Squadron.
It is important to understand that hull number letter prefixes are not acronyms, and should not be carelessly treated as abbreviations of ship type classifications. Thus, "DD" does not stand for anything more than "Destroyer". "SS" simply means "Submarine". And "FF", the post-1975 type code for "Frigate", most emphatically is not translated "fast frigate"!.
This page provides links to the hull numbers of many U.S.
Navy Ships whose photos are available in the Online Library.
Select the hull number series of the ship you want from the
listing below, and follow subsequent pages to locate photographs
of that ship that have been posted on the Online Library.
Note: This listing is under construction and is only complete for those hull number series which have active links below.
If the hull number series does not have an active link on these pages, contact the Photographic
