A ship prefix is a combination of letters, usually abbreviations, used in front of the name of a civilian or naval ship that has historically served numerous purposes, such as identifying the vessel's mode of propulsion, purpose, or ownership/nationality. In the modern environment, prefixes are cited inconsistently in civilian service, whereas in government service a vessel's prefix is seldom omitted due to government regulations dictating that a certain prefix be used. Today the common practice is to use a single prefix for all warships of a nation's navy, and other prefixes for auxiliaries and ships of allied services, such as coast guards. For example, the modern navy of Japan adopts the prefix "JS" – Japanese Ship. However, not all navies use prefixes. Among the blue-water navies,[1] those of France, Brazil, China, Russia, Germany, and Spain do not use ship prefixes. NATO designations such as FS (French Ship), FGS (Federal German Ship), and SPS (Spanish Ship) can be used if needed.[citation needed]
Historically, prefixes for civilian vessels often identified the vessel's mode of propulsion, such as "MV" (motor vessel), "SS" (screw steamer;[2] often cited as "steam ship"), or "PS" (paddle steamer).[3][2]
These days, general civilian prefixes are used inconsistently, and frequently not at all. In terms of abbreviations that may reflect a vessel's purpose or function, technology has introduced a broad variety of differently named vessels onto the world's oceans, such as "LPGC" (liquified petroleum gas carrier), or "TB" (tug-boat), or "DB" (derrick barge). In many cases though, these abbreviations are used for purely formal, legal identification and are not used colloquially or in the daily working environment. Prefixes indicating a vessel's purpose (e.g., "RMS" for a Royal Mail ship or "RV" for research vessel) are also used.[citation needed]
Prefixes used for naval ships primarily reflect ownership, but may also indicate a vessel's type or purpose as a sub-set. Historically, the most significant navy was Britain's Royal Navy, which has usually used the prefix "HMS", standing for "His/Her Majesty's Ship". The Royal Navy also adopted nomenclature that reflected a vessel's type or purpose, e.g. HM Sloop. Commonwealth navies adopted a variation, with, for example, HMAS, HMCS, and HMNZS pertaining to Australia, Canada, and New Zealand, respectively.
In the early days of the United States Navy, abbreviations often included the type of vessel, for instance "USF" (United States Frigate), but this method was abandoned by President Theodore Roosevelt's Executive Order No. 549 of 1907, which made "United States Ship" (USS) the standard signifier for USN ships on active commissioned service.[4][5] United States Navy prefixes officially only apply while a ship is in active commission, with only the name used before or after a period of commission and for all vessels "in service" rather than commissioned status.[5][6]
However, not all navies used prefixes; this includes the significant navies of China, France and Russia.[citation needed]
From the 20th century onwards, most navies identify ships by letters or hull numbers (pennant numbers)[7] or a combination of such. These identification codes were, and still are, painted on the side of the ship. Each navy has its own system: the United States Navy uses hull classification symbols, and the Royal Navy (e.g. 'D35' is destroyer 35 – HMS Dragon) and other navies of Europe and the Commonwealth use pennant numbers.[citation needed]
These tables list both current and historical prefixes known to have been used.[8]
"Royal Ship" (Greek: Βασιλικόν Πλοίον, romanized:Vassilikón Ploíon); Some English Language authors uses RHNS for Royal Hellenic Navy Ship or HHMS for His Hellenic Majesty's Ship.
His Imperial Japanese Majesty Ship (Used externally, between the Meiji Era and the Washington Naval Treaty. Though abandoned later on, Japanese vessels were still referred as such during World War II. The unofficial name IJN stands for "Imperial Japanese Navy" is frequently used in various sources and media.
His Norwegian Majesty's Yacht (Norwegian: Kongenskipet). The only vessel with the prefix, HNoMYNorge, is owned by the King but crewed by his Navy since 1948.
King's Sloop Norwegian: Kongesjaluppen Used on two small motorised pleasure vessels named Stjernen & Stjernen(II) owned by the King from 1899-1940 and 1945-present.
Hans/Hennes Majestäts Skepp (His/Her Majesty's Ship) HSwMS (His/Her Swedish Majesty's Ship) is used in English to avoid confusion with Royal Navy ships
Vietnam People's Navy Ship. The Vietnam People's Navy does not internally and formally use this designation despite its unofficial but frequent usage by foreign media at international events. Since a major portion of the Vietnamese fleet is not named literally and only has standardized non-prefixed hull numbers, the VPNS prefix is sometimes used with the ship's hull number (for example, VPNS 20)[34] to make it look cosmetically more synchronous and consistent with other navies' prefixed ship names in international activities.

Prefix conventions
The designations for United Kingdom ships applied at the time of the British Empire, before the establishment of separate navies for the Dominions.
In the Royal Netherlands Navy, "HNLMS" is the prefix in English, a translation of the Dutch original "Hr.Ms." or "Zr.Ms.". "Hr.Ms." should preferably not be used in English-language documents; nevertheless it is often seen on the World Wide Web. Until the moment a Dutch naval ship officially enters active service in the fleet, the ship's name is used without the prefix.[35] Since King Willem-Alexander succeeded Queen Beatrix on 30 April 2013, "Hr.Ms." is replaced by "Zr.Ms.".
In Australia, the prefix NUSHIP is used to denote ships that have yet to be commissioned into the fleet.[36]
In the United States, all prefixes other than "USS", "USNS", "USNV", and "USRC" were made obsolete in 1901, when President Theodore Roosevelt issued an Executive order fixing American naval nomenclature.[5] USRC was replaced by USCGC when the Revenue Cutter Service merged with the United States Lifesaving Service to become the United States Coast Guard in 1915.[37] USLHT also was replaced by USCGC when the United States Lighthouse Service became a part of the U.S. Coast Guard in 1939. USC&GS was replaced by NOAAS when the United States Coast and Geodetic Survey merged with other U.S. Government scientific agencies to form the National Oceanic and Atmospheric Administration (NOAA) in 1970. USFC was replaced by USFS when the United States Commission on Fish and Fisheries was reorganized as the U.S. Bureau of Fisheries in 1903, and USFS in turn was replaced in 1940 by US FWS when the Bureau of Fisheries merged with the United States Department of the Interior's Division of Biological Survey to form the Department of the Interior's Fish and Wildlife Service (which in 1956 was reorganized as the United States Fish and Wildlife Service). Seagoing ships Fish and Wildlife Service ships with the prefix US FWS that were transferred to NOAA when NOAA was created in 1970 switched to the NOAAS prefix.
A United States Navy ship that is not in active commission does not hold the title of United States Ship with simply the name without prefix used before and after commissioned service.[5] Vessels, such as yard and harbor craft that are not commissioned and "in service" are officially referred to by name or hull number without prefix.[5] Prior to commissioning, ships may be described as a pre-commissioning unit or PCU; for example, USS Gerald R. Ford was described as the "pre-commissioning unit (PCU) Gerald R. Ford" prior to her commissioning in 2017.[38][5]Military Sealift Command (MSC) civilian crewed ships "in service" are given the prefix United States Naval Ship (USNS).[5]
When it is stricken from the fleet list, a ship typically has the prefix "ex-" added to its name, to distinguish it from any active ships bearing the same name. For example, after USS Constellation (CV-64) was retired in 2003, she became referred to as ex-Constellation.
In science fiction
Fictional equivalents of tri-letter prefixes frequently appear in English-language science fiction works, applied to seafaring and spaceborne ships alike.
Star Trek – the United Federation of Planets uses the prefix "USS" for its starships. Dialogue in earlier episodes of the series indicated that it referred to "United Space Ship".[39] In the alternate "Mirror Universe", the Terran Empire use an "ISS" prefix instead. Other races use different prefixes for their ships:
Klingons use IKS (Imperial Klingon Ship) or IKC (Imperial Klingon Cruiser).
Romulan vessels typically receive the prefix IRW (Imperial Romulan Warbird), or RIS where some speculate that it means "Romulan Imperial Ship", and ChR. (ChR is from novelist Diane Duane's imagining of the Star Trek Universe, in which the Romulans refer to their home planet as "Ch'Rihan". Though Duane's version has a loyal following among many fans, it is not considered official Star Trek canon; similarly, the Ferengi designation of FMS, and the Cardassian CDS, are also not canon.)
Babylon 5 – The Earth Alliance uses the prefix "EAS" for "Earth Alliance Ship". Some fan material also uses it for "Earth Alliance Station".
Elite: Dangerous – The Federation uses the prefix "FNS" (Federal Naval Ship) for some military ships. The Empire uses "INV" (Imperial Naval Vessel). The alliance uses "ADF" (Alliance Defense Force).
Halo – United Nations Space Command spacecraft use the prefix "UNSC". The Covenant use three letter designations for ship class such as CAS or CSO
Mass Effect – features several prefixes, primarily "SSV" for "Systems Alliance space vehicle"[40] and "MSV" for "Merchant Space Vehicle", used on numerous human commercial ships, as well as "PFS" for a Turian Hierarchy naval craft, and a freighter AML Demeter of unknown affiliation.
Dead Space – "USG", standing for "United Spacefaring Guild", which oversees civilian spacecraft operation, including the planet-cracker class leader USG Ishimura of the Concordance Extraction Corporation; "USM" for the Earth Defense Force of EarthGov; and "CMS" for its predecessor, the Sovereign Colonies Armed Forces.
StarCraft: Brood War – The United Earth Directorate uses DSS (presumably for Directorate Space Ship, e. g. DSS Aleksander); the Terran Confederacy used CSF (Confederate Space Fleet, e. g. CSF Ragnorak) for their battlecruisers.
Killzone – The Interplanetary Strategic Alliance (ISA) uses "ISC", for Interplanetary Strategic Cruiser.
Alien – The ships use prefix "USCSS" for "United States Cargo SpaceShip" on the Nostromo, Prometheus, and Covenant.
The Lost Fleet – The Alliance use the prefix "ASN" for "Allied Systems Navy" (or possibly "Alliance of Systems Navy"), the Syndicate Worlds do not use prefixes.
CoDominium – CoDominium vessels use the prefix "CDS" for CoDominium Ship.
"Honorverse" – The Manticoran kingdom uses "HMS" as a prefix, the Graysons use "GNS"(Grayson Navy Ship), and the Havenite ships use "PNS" (People's Navy Ship) and later "RHNS" (Republic of Haven Navy Ship), being reflections of actual ship prefixing traditions, and mirroring the Napoleonic wars. The Solarian League uses "SLNS" (Solarian League Navy Ship) and the Andermani Empire uses "IANS" for Imperial Andermani Navy Ship.
The Culture – Ships are identified by a three-letter prefix denoting class (such as GSV for "General Systems Vehicle" or ROU for "Rapid Offensive Unit"), followed by their personal name.
The Expanse – Ships of the United Nations Navy use the prefix "UNN," while ships of the Martian Congressional Republic Navy are prefixed with "MCRN". The Nauvoo, a generation ship commissioned by the Church of Latter Day Saints was prefixed with "LDSS" for "Latter Day Saints' Ship", and later changed to "OPAS" and re-christened as the "OPAS Behemoth" representing the Outer Planets Alliance.
Unreal Tournament – Ships mentioned there have prefixes such as ITV ("Interstellar Transport Vessel", the first non-tutorial match in the tournament happens on board of ITV Oblivion) and ISV ("Interstellar Science Vessel", ship's name being ISV-Kran from Unreal).
Unreal: Return to Na Pali – ISV (ISV-Kran) and UMS ("Unified Military Services", a prefix for warships).
The Orville—The Planetary Union uses the prefix "USS", presumably for "Union Space Ship" (in homage to Star Trek).
Treasure Planet: Battle at Procyon - The Terran Empire uses the prefix RLS, which stands for Royal Light Ship; this is also a direct homage to Robert Louis Stevenson, author of the original Treasure Island. The Procyon Expanse uses the prefix PSR, which stands for Procyon Star Runner.
Destroyermen - the Grand Alliance uses the "USS" prefix, since all Allied warships are run by the Americaan (sic) Clan. The Alliance's only airship is given the prefix "UHAS" (United Homes Air Ship). The Empire of New Britain Isles uses "HIMS" (His/Her Imperial Majesty's Ship). The Republic of Real People uses "RRPS" (Republic of Real People Ship). The New United States uses "NUSS" (New United States Ship). Neither the Holy Dominion nor the League of Tripoli use prefixes, although the KMS Hessen is mentioned once, it is not clear if the prefix is internally used or not.
Titanfall - The Interstellar Manufacturing Corporation, the main antagonists of the series, use the "IMS" prefix. The origin of this prefix is unknown.
FreeSpace - Various ship prefixes are used depending on the species, faction allegiance, and class of the vehicle. Prominent examples include: "GT" and "GV" for "Galactic Terran" and "Galactic Vasudan" respectively, "NT" for "Neo-Terran," "PV" for "Parliamentary Vasudan," and just "S" for "Shivan." These are then further supplemented with a type of ship identifier following the species and faction prefixes, such as "B" for "Bomber," "C" for "Cruiser," "Cv" for "Corvette," "D" for "Destroyer," and "F" for "Fighter," among many examples. As such, "PVD" would indicate a "Parliamentary Vasudan Destroyer," "NTF" would indicate a "Neo-Terran Fighter," "GTC" would indicate a "Galactic Terran Cruiser", "GVCv" would indicate a "Galactic Vasudan Corvette," and "SB" would indicate a "Shivan Bomber."
"Helldivers 2" - "SES" is used for "Super Earth Ship"

The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
A navy, naval force, military maritime fleet, war navy, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields.
United States Ship is a ship prefix used to identify a commissioned ship of the United States Navy and applies to a ship only while it is in commission. Before commissioning, the vessel may be referred to as a "pre-commissioning unit" (PCU), but is officially referred to by name with no prefix. After decommissioning, it is referred to by name with no prefix, though people commonly refer to those ships with the prefix "ex-", as in ex-ship name. In-service but non-commissioned Navy ships go by the prefix USNS, which stands for United States Naval Ship.
USS Freedom (ID-3024) was a cargo and transport ship in the United States Navy in World War I. Originally Wittekind for the North German Lloyd line, the ship also served as USAT Iroquois and USAT Freedom after being seized by the United States in 1917.
The jack of the United States, referred to as the Union Jack by the U.S. Navy, is a maritime jack flag flown on the bow of U.S. vessels that are moored or anchored. In addition to commissioned U.S. Navy ships, the jack is used by the U.S. Coast Guard, the Military Sealift Command, the ships of the National Oceanic and Atmospheric Administration, and other U.S. government entities. While anchored or moored, the jack is flown on the bow of a ship, and the ensign is flown on the stern. Once under way, the jack is lowered.
USS Bear was a dual steam-powered and sailing ship built with six-inch (15.2 cm)-thick sides which had a long life in various cold-water and ice-filled environments. She was a forerunner of modern icebreakers and had a diverse service life. According to the United States Coast Guard official website, Bear is described as "probably the most famous ship in the history of the Coast Guard."
The Command at Sea insignia is a badge of the United States' seagoing services worn by officers on their uniforms to denote that they are the commander, or formerly a commander, of a warship. If the wearer is currently the commander of a warship, it is worn above the nametag, which is worn a quarter of an inch above the right chest pocket on a uniform shirt. Afterwards, the pin is moved to the left side of the shirt or jacket. For the commanders of land-based installations, a different but similar version known as the Command Ashore insignia instead.

NOAAS Thomas Jefferson is a National Oceanic and Atmospheric Administration (NOAA) hydrographic survey vessel in service since 2003. The ship was built for the United States Navy as USNS Littlehales (T-AGS-52) serving as one of two new coastal hydrographic survey vessels from 1992 until transfer to NOAA in 2003 when it was named after Founding Father and third U.S. president, Thomas Jefferson.
USS Flamingo (AM-32) was a Lapwing-class minesweeper built for the United States Navy near the end of World War I. After service overseas clearing mines after the Armistice, the ship was laid up until 1922 when she was transferred to the United States Department of Commerce for use by the United States Coast and Geodetic Survey. Renamed USC&GS Guide, the ship operated as a survey vessel along the West Coast of the United States for 17 years, making significant contributions to navigation, hydrographic surveying, and oceanography. In June 1941, Guide was transferred back to the Navy, converted into a salvage ship, and renamed USS Viking (ARS-1). As Viking, she worked primarily from bases in California until 1953, when she was sold for scrapping.
USS Oceanographer (AGS-3) was a survey ship of the United States Navy during World War II that produced charts chiefly of passages in the Solomon Islands area of the Pacific Ocean. Upon transfer to the Navy, she had initially briefly been named and classed as gunboat USS Natchez (PG-85). Before her World War II Navy service, she had been USC&GS Oceanographer (OSS-26), a survey ship with the United States Coast and Geodetic Survey from 1930.
The United States Coast and Geodetic Survey was the first scientific agency of the United States Government. It existed from 1807 to 1970, and throughout its history was responsible for mapping and charting the coast of the United States, and later the coasts of U.S. territories. In 1871, it gained the additional responsibility of surveying the interior of the United States and geodesy became a more important part of its work, leading to it being renamed the U.S. Coast and Geodetic Survey in 1878.
USS Maple, was a lighthouse tender that served in the United States Navy from 1893 to 1899, seeing service as an auxiliary ship during the Spanish–American War in 1898, and from 1917 to 1919, operating as a patrol vessel during World War I. She also served as USLHT Maple in the United States Lighthouse Board fleet from 1899 to 1910 and in the United States Lighthouse Service from 1910 to 1933.
USS Raeo (SP-588) was a United States Navy patrol vessel in commission from 1917 to 1919. Prior to her U.S. Navy service, she operated as the motor passenger vessel Raeo from 1908 to 1917. After the conclusion of her U.S. Navy career, she served as the fishery patrol vessel USFS Kittiwake in the United States Bureau of Fisheries fleet from 1919 to 1940 and as US FWS Kittiwake in the Fish and Wildlife Service fleet from 1940 to 1942 and from 1944 to at least 1945, and perhaps as late as 1948. During World War II, she again served in the U.S. Navy, this time as the yard patrol boat USS YP-199. She was the civilian fishing vessel Raeo from 1948 to 1957, then operated in various roles as Harbor Queen from 1957 to 1997. She became Entiat Princess in 1998 and as of 2009 was still in service.
The second USS Calypso (SP-632) was a United States Navy patrol vessel in commission from 1917 to 1919. She originally operated as the private motorboat Calypso from 1909 to 1917. After the conclusion of her U.S. Navy career, she served as the fishery patrol vessel in the United States Bureau of Fisheries fleet from 1919 to 1940 as USFS Merganser and in the Fish and Wildlife Service fleet as US FWS Merganser from 1940 to 1942.
USS Onward (SP-311), a former yacht named Galatea and then Ungava was a patrol yacht acquired by the U.S. Navy during World War I. She was transferred to the United States Coast and Geodetic Survey where she served briefly until return to the Navy for a brief time before her disposal by sale. She was renamed Thelma Phoebe.
In the United States Navy, United States Coast Guard, United States Public Health Service Commissioned Corps, and National Oceanic and Atmospheric Administration Commissioned Officer Corps, captain is the senior-most commissioned officer rank below that of flag officer. The equivalent rank is colonel in the United States Army, Air Force, Space Force, and Marine Corps.
USS Lewis B. Puller (ESB-3), is the first purpose-built expeditionary mobile base vessel for the United States Navy, and the second ship to be named in honor of Chesty Puller. The lead ship in her class of expeditionary mobile bases, she is also a sub-variant of the Montford Point-class expeditionary transfer docks. Lewis B. Puller replaced USS Ponce with the U.S. Fifth Fleet in the Persian Gulf in late 2017.
Pre-commissioning unit is a designation used by the United States Navy to describe vessels under construction prior to their official commissioning. For example, prior to her commissioning, USS Gerald R. Ford had been described by the Navy as "PCU Gerald R. Ford ". Such descriptions can appear in the media as well. "PCU" is a temporary, descriptive term, and is not a ship prefix or a part of the ship's official name. Until they are commissioned, U.S. Navy vessels are officially identified by their given name and hull number, such as Gerald R. Ford.
