The system was a simple one in which each ship received a number which was appended to its ship type, fully spelled out, and added parenthetically after the ship's name when deemed necessary to avoid confusion between ships. Under this system, for example, the <a href="/wiki/Battleship" title="Battleship">battleship</a> <a href="/wiki/USS_Indiana_(BB-1)" title="USS Indiana (BB-1)"><i>Indiana</i></a> was USS <i>Indiana</i> (Battleship No. 1), the <a href="/wiki/Cruiser" title="Cruiser">cruiser</a> <a href="/wiki/USS_Olympia_(C-6)" title="USS Olympia (C-6)"><i>Olympia</i></a> was USS <i>Olympia</i> (Cruiser No. 6), and so on. Beginning in 1907, some ships also were referred to alternatively by single-letter or three-letter codes—for example, USS <i>Indiana</i> (Battleship No. 1) could be referred to as USS <i>Indiana</i> (B-1) and USS <i>Olympia</i> (Cruiser No. 6) could also be referred to as USS <i>Olympia</i> (C-6), while USS <i>Pennsylvania</i> (Armored Cruiser No. 4) could be referred to as USS <i>Pennsylvania</i> (ACR-4). However, rather than replacing it, these codes coexisted and were used interchangeably with the older system until the modern system was instituted on 17 July 1920.<sup id="cite_ref-DerDigiCru1_1-0" class="reference"><a href="#cite_note-DerDigiCru1-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>During <a href="/wiki/World_War_I" title="World War I">World War I</a>, the U.S. Navy acquired large numbers of privately owned and commercial ships and craft for use as <a href="/wiki/Patrol_vessel" class="mw-redirect" title="Patrol vessel">patrol vessels</a>, <a href="/wiki/Minelayer" title="Minelayer">mine warfare vessels</a>, and various types of naval <a href="/wiki/Auxiliary_ship" title="Auxiliary ship">auxiliary ships</a>, some of them with identical names. To keep track of them all, the Navy assigned unique identifying numbers to them. Those deemed appropriate for patrol work received <a href="/wiki/Section_patrol" class="mw-redirect" title="Section patrol">section patrol</a> numbers (SP), while those intended for other purposes received "identification numbers", generally abbreviated "Id. No." or "ID;" some ships and craft changed from an SP to an ID number or vice versa during their careers, without their unique numbers themselves changing, and some ships and craft assigned numbers in anticipation of naval service were never acquired by the Navy. The SP/ID numbering sequence was unified and continuous, with no SP number repeated in the ID series or vice versa so that there could not be, for example, both an "SP-435" and an "Id. No. 435". The SP and ID numbers were used parenthetically after each boat's or ship's name to identify it; although this system pre-dated the modern hull classification system and its numbers were not referred to at the time as "hull codes" or "hull numbers," it was used in a similar manner to today's system and can be considered its precursor.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="United_States_Revenue_Cutter_Service_and_United_States_Coast_Guard">United States Revenue Cutter Service and United States Coast Guard</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hull_classification_symbol&action=edit&section=3" title="Edit section: United States Revenue Cutter Service and United States Coast Guard"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The <a href="/wiki/United_States_Revenue_Cutter_Service" title="United States Revenue Cutter Service">United States Revenue Cutter Service</a>, which merged with the <a href="/wiki/United_States_Lifesaving_Service" class="mw-redirect" title="United States Lifesaving Service">United States Lifesaving Service</a> in January 1915 to form the modern <a href="/wiki/United_States_Coast_Guard" title="United States Coast Guard">United States Coast Guard</a>, began following the Navy's lead in the 1890s, with its <a href="/wiki/United_States_Coast_Guard_Cutter" title="United States Coast Guard Cutter">cutters</a> having parenthetical numbers called <a href="/wiki/Naval_Registry_Identification_Number" title="Naval Registry Identification Number">Naval Registry Identification Numbers</a> following their names, such as (Cutter No. 1), etc. This persisted until the Navy's modern hull classification system's introduction in 1920, which included Coast Guard ships and craft. </p> <div class="mw-heading mw-heading3"><h3 id="United_States_Coast_and_Geodetic_Survey">United States Coast and Geodetic Survey</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hull_classification_symbol&action=edit&section=4" title="Edit section: United States Coast and Geodetic Survey"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Like the U.S. Navy, the <a href="/wiki/United_States_Coast_and_Geodetic_Survey" title="United States Coast and Geodetic Survey">United States Coast and Geodetic Survey</a> – a uniformed seagoing service of the <a href="/wiki/United_States_Government" class="mw-redirect" title="United States Government">United States Government</a> and a predecessor of the <a href="/wiki/National_Oceanic_and_Atmospheric_Administration" title="National Oceanic and Atmospheric Administration">National Oceanic and Atmospheric Administration</a> (NOAA) – adopted a hull number system for its fleet in the 20th century.

A fourth designation, "ASV" for "auxiliary survey vessel," included even smaller vessels. In each case, a particular ship received a unique designation based on its classification and a unique hull number separated by a space rather than a hyphen; for example, the third Coast and Geodetic Survey ship named <i>Pioneer</i> was an ocean survey ship officially known as <a href="/wiki/USC%26GS_Pioneer_(OSS_31)" class="mw-redirect" title="USC&GS Pioneer (OSS 31)">USC&GS <i>Pioneer</i> (OSS 31)</a>.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> The Coast and Geodetic Survey<span class="nowrap" style="padding-left:0.1em;">'</span>s system persisted after the creation of NOAA in 1970, when NOAA took control of the Survey<span class="nowrap" style="padding-left:0.1em;">'</span>s fleet, but NOAA later changed to its modern hull classification system. </p> <div class="mw-heading mw-heading3"><h3 id="United_States_Fish_and_Wildlife_Service">United States Fish and Wildlife Service</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hull_classification_symbol&action=edit&section=5" title="Edit section: United States Fish and Wildlife Service"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The Fish and Wildlife Service, created in 1940 and reorganized as the <a href="/wiki/United_States_Fish_and_Wildlife_Service" title="United States Fish and Wildlife Service">United States Fish and Wildlife Service</a> (USFWS) in 1956, adopted a hull number system for its <a href="/wiki/Fisheries_science" title="Fisheries science">fisheries</a> <a href="/wiki/Research_ship" class="mw-redirect" title="Research ship">research ships</a> and <a href="/wiki/Patrol_vessel" class="mw-redirect" title="Patrol vessel">patrol vessels</a>.

In the new system, all hull classification symbols are at least two letters; for basic types the symbol is the first letter of the type name, doubled, except for aircraft carriers. </p><p>The combination of symbol and hull number identifies a modern Navy ship uniquely. A heavily modified or re-purposed ship may receive a new symbol, and either retain the hull number or receive a new one. For example, the heavy gun cruiser <a href="/wiki/USS_Boston_(CA-69)" title="USS Boston (CA-69)">USS <i>Boston</i> (CA-69)</a> was converted to a gun/missile cruiser, changing the hull number to CAG-1. Also, the system of symbols has changed a number of times both since it was introduced in 1907 and since the modern system was instituted in 1920, so ships' symbols sometimes change without anything being done to the physical ship.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p><p>Hull numbers are assigned by classification.

In other navies, such a ship generally was referred to as a "<a href="/wiki/Flotilla_leader" title="Flotilla leader">flotilla leader</a>", or "destroyer leader". Hence the U.S. Navy's use of "DL" for "frigate" prior to 1975, while "frigates" in other navies were smaller than destroyers and more like what the U.S. Navy termed a "<a href="/wiki/Destroyer_escort" title="Destroyer escort">destroyer escort</a>", "<a href="/wiki/Ocean_escort" title="Ocean escort">ocean escort</a>", or "DE".

It later adopted a new system of ship classification, which it still uses today. In its modern system, the NOAA fleet is divided into two broad categories, research ships and survey ships. The research ships, which include <a href="/wiki/Oceanography" title="Oceanography">oceanographic</a> and fisheries research vessels, are given hull numbers beginning with "R", while the survey ships, generally <a href="/wiki/Hydrography" title="Hydrography">hydrographic</a> survey vessels, receive hull numbers beginning with "S". The letter is followed by a three-digit number; the first digit indicates the NOAA "class" (i.e., size) of the vessel, which NOAA assigns based on the ship's <a href="/wiki/Gross_ton" class="mw-redirect" title="Gross ton">gross tonnage</a> and <a href="/wiki/Horsepower" title="Horsepower">horsepower</a>, while the next two digits combine with the first digit to create a unique three-digit identifying number for the ship. </p><p>Generally, each NOAA hull number is written with a space between the letter and the three-digit number, as in, for example, <a href="/wiki/NOAAS_Nancy_Foster" title="NOAAS Nancy Foster">NOAAS <i>Nancy Foster</i> (R 352)</a> or <a href="/wiki/NOAAS_Thomas_Jefferson" title="NOAAS Thomas Jefferson">NOAAS <i>Thomas Jefferson</i> (S 222)</a>.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p><p>Unlike in the U.S. Navy system, once an older NOAA ship leaves service, a newer one can be given the same hull number; for example, "S 222" was assigned to <a href="/wiki/NOAAS_Mount_Mitchell" title="NOAAS Mount Mitchell">NOAAS <i>Mount Mitchell</i> (S 222)</a>, then assigned to NOAAS <i>Thomas Jefferson</i> (S 222), which entered NOAA service after <i>Mount Mitchell</i> was stricken. </p> <div class="mw-heading mw-heading2"><h2 id="United_States_Navy_hull_classification_codes">United States Navy hull classification codes</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hull_classification_symbol&action=edit&section=11" title="Edit section: United States Navy hull classification codes"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>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. Although 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. </p><p>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. </p><p>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" is the post-1975 type code for "Frigate."<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> </p><p>The hull classification codes for ships in active duty in the United States Navy are governed under Secretary of the Navy Instruction 5030.8D.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Warships">Warships</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hull_classification_symbol&action=edit&section=12" title="Edit section: Warships"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Warships are designed to participate in combat operations. </p><p>The origin of the two-letter code derives from the need to distinguish various cruiser subtypes.<sup id="cite_ref-DerDigiCru1_1-1" class="reference"><a href="#cite_note-DerDigiCru1-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p> <table class="wikitable"> <tbody><tr> <td>Battleship </td> <td>Heavy gun-armed vessel (–1962) </td> <th>BB </th></tr> <tr> <td align="center" rowspan="5">Cruiser </td> <td>armored (1921–1931)<br />heavy (1931–1975) </td> <th>CA </th></tr> <tr> <td>large (–1947) </td> <th>CB </th></tr> <tr> <td>battle<br />command<br />(–1961) </td> <th>CC </th></tr> <tr> <td>light (–1950) </td> <th>CL </th></tr> <tr> <td>aviation or <i>voler</i> </td> <th>CV </th></tr> <tr> <td align="center" rowspan="2">Destroyer </td> <td>ship </td> <th>DD </th></tr> <tr> <td>escort </td> <th>DE </th></tr></tbody></table> <div class="mw-heading mw-heading4"><h4 id="Aircraft_carrier_type">Aircraft carrier type</h4><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hull_classification_symbol&action=edit&section=13" title="Edit section: Aircraft carrier type"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Aircraft carriers are ships designed primarily for the purpose of conducting combat operations by aircraft which engage in attacks against airborne, surface, sub-surface and shore targets.
