Ship prefix

From Wikipedia, in a visual modern way
This ship's prefix "MSC" indicates the owner, Mediterranean Shipping Company.
This ship's prefix "MSC" indicates the owner, Mediterranean Shipping Company.

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.

Ship

Ship

A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce.

Warship

Warship

A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are usually faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations.

Coast guard

Coast guard

A coast guard or coastguard is a maritime security organization of a particular country. The term embraces wide range of responsibilities in different countries, from being a heavily armed military force with customs and security duties to being a volunteer organization tasked with search and rescue without law enforcement authority. In most countries, a typical coast guard's functions are distinct from those of the navy and the transit police, while in certain countries has similarities to both.

Blue-water navy

Blue-water navy

A blue-water navy is a maritime force capable of operating globally, essentially across the deep waters of open oceans. While definitions of what actually constitutes such a force vary, there is a requirement for the ability to exercise sea control at long range.

Usage

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" (Royal Mail ship) or "RV" (research vessel)) are also used.

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.

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.

These tables list both current and historical prefixes known to have been used.[8]

Motor ship

Motor ship

A motor ship or motor vessel is a ship propelled by an internal combustion engine, usually a diesel engine. The names of motor ships are often prefixed with MS, M/S, MV or M/V.

Screw steamer

Screw steamer

A screw steamer or screw steamship is an old term for a steamship or steamboat powered by a steam engine, using one or more propellers to propel it through the water. Such a ship was also known as an "iron screw steam ship".

Paddle steamer

Paddle steamer

A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans.

Royal Mail Ship

Royal Mail Ship

Royal Mail Ship, usually seen in its abbreviated form RMS, is the ship prefix used for seagoing vessels that carry mail under contract to the British Royal Mail. The designation dates back to 1840. Any vessel designated as "RMS" has the right both to fly the pennant of the Royal Mail when sailing and to include the Royal Mail "crown" insignia with any identifying device and/or design for the ship.

Research vessel

Research vessel

A research vessel is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters.

Royal Navy

Royal Navy

The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.

Sloop

Sloop

A sloop is a sailboat with a single mast typically having only one headsail in front of the mast and one mainsail aft of (behind) the mast. Such an arrangement is called a fore-and-aft rig, and can be rigged as a Bermuda rig with triangular sails fore and aft, or as a gaff-rig with triangular foresail(s) and a gaff rigged mainsail. Sailboats can be classified according to type of rig, and so a sailboat may be a sloop, catboat, cutter, ketch, yawl, or schooner. A sloop usually has only one headsail, although an exception is the Friendship sloop, which is usually gaff-rigged with a bowsprit and multiple headsails. If the vessel has two or more headsails, the term cutter may be used, especially if the mast is stepped further towards the back of the boat.

Frigate

Frigate

A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat.

Hull number

Hull number

A hull number is a serial identification number given to a boat or ship. For the military, a lower number implies an older vessel. For civilian use, the HIN is used to trace the boat's history. The precise usage varies by country and type.

Hull classification symbol

Hull classification symbol

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.

HMS Dragon (D35)

HMS Dragon (D35)

HMS Dragon is the fourth ship of the Type 45 or Daring-class air-defence destroyers built for the Royal Navy. She was launched in November 2008 and commissioned on 20 April 2012.

Pennant number

Pennant number

In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number. Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship.

Ammunition ship

Ammunition ship

An ammunition ship is an auxiliary ship specially configured to carry ammunition, usually for naval ships and aircraft. An ammunition ship's cargo handling systems, designed with extreme safety in mind, include ammunition hoists with airlocks between decks, and mechanisms for flooding entire compartments with sea water in case of emergencies. Ammunition ships most often deliver their cargo to other ships using underway replenishment, using both connected replenishment and vertical replenishment. To a lesser extent, they transport ammunition from one shore-based weapons station to another.

Combat stores ship

Combat stores ship

Combat stores ships, or storeships, are ships used to store naval supplies. They are used to deliver supplies such as provisions and fuel to combat ships on extended deployments. The United States Navy operates the Sirius and Mars classes and the Royal Navy operates the Fort Rosalie and Fort Victoria classes. Storeships should not be confused with fast combat support ships which are high speed auxiliary ships or tenders which provide maintenance support to flotillas.

Anchor handling tug supply vessel

Anchor handling tug supply vessel

Anchor Handling Tug Supply (AHTS) vessels are mainly built to handle anchors for oil rigs, tow them to location, and use them to secure the rigs in place. AHTS vessels sometimes also serve as Emergency Response and Rescue Vessels (ERRVs) and as supply transports.

T1 tanker

T1 tanker

The T1 tanker or T1 are a class of sea worthy small tanker ships used to transport fuel oil before and during World War II, Korean War and Vietnam War. The T1 tanker classification is still in use today. T1 tankers are about 200 to 250 feet in length and are able to sustain a top speed of about 12 knots. The hull designation AO is used by the US Navy to denote the ship is a T1 oil tanker and AOG that the T1 is a gasoline tanker. The small size allows the T1 to enter just about any sea port or to anchor around a small island, this was very useful during the Pacific War. The T1 tanker can carry about 48,000 to 280,000 bbls. Some T1 tankers were used to transport goods other than oil, a few were used for black oil-crude oil, diesel, chemicals and rarely bulk cargo like grain. T1 tankers are also called liquid cargo carriers. The T1 tanker has about a 6,000 to 35,000 deadweight tonnage (DWT) of cargo. The small size also gives the ships short turn around time for repair, cleaning, loading and unloading. A T1 tanker carrying dirty cargo, like crude oil needs a few weeks of labor to clean before carrying clean cargo. Most T1 ships during World War II were named after major oil fields.

Replenishment oiler

Replenishment oiler

A replenishment oiler or replenishment tanker is a naval auxiliary ship with fuel tanks and dry cargo holds which can supply both fuel and dry stores during underway replenishment (UNREP) at sea. Many countries have used replenishment oilers.

Roll-on/roll-off

Roll-on/roll-off

Roll-on/roll-off ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, trailers, and railroad cars, that are driven on and off the ship on their own wheels or using a platform vehicle, such as a self-propelled modular transporter. This is in contrast to lift-on/lift-off (LoLo) vessels, which use a crane to load and unload cargo.

Container ship

Container ship

A container ship is a cargo ship that carries all of its load in truck-size intermodal containers, in a technique called containerization. Container ships are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo.

Cable layer

Cable layer

A cable layer or cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, electric power transmission, military, or other purposes. Cable ships are distinguished by large cable sheaves for guiding cable over bow or stern or both. Bow sheaves, some very large, were characteristic of all cable ships in the past, but newer ships are tending toward having stern sheaves only, as seen in the photo of CS Cable Innovator at the Port of Astoria on this page. The names of cable ships are often preceded by "C.S." as in CS Long Lines.

Crane vessel

Crane vessel

A crane vessel, crane ship or floating crane is a ship with a crane specialized in lifting heavy loads. The largest crane vessels are used for offshore construction. Conventional monohulls are used, but the largest crane vessels are often catamaran or semi-submersible types as they have increased stability. On a sheerleg crane, the crane is fixed and cannot rotate, and the vessel therefore is manoeuvered to place loads.

Diving support vessel

Diving support vessel

A diving support vessel is a ship that is used as a floating base for professional diving projects. Basic requirements are the ability to keep station accurately and reliably throughout a diving operation, often in close proximity to drilling or production platforms, for positioning to degrade slowly enough in deteriorating conditions to recover divers without excessive risk, and to carry the necessary support equipment for the mode of diving to be used.

Deep-submergence vehicle

Deep-submergence vehicle

A deep-submergence vehicle (DSV) is a deep-diving crewed submersible that is self-propelled. Several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs, which are used for exploration and surveying, and DSRVs, which are intended to be used for rescuing the crew of a sunken navy submarine, clandestine (espionage) missions, or both. DSRVs are equipped with docking chambers to allow personnel ingress and egress via a manhole.

Floating production storage and offloading

Floating production storage and offloading

A floating production storage and offloading (FPSO) unit is a floating vessel used by the offshore oil and gas industry for the production and processing of hydrocarbons, and for the storage of oil. An FPSO vessel is designed to receive hydrocarbons produced by itself or from nearby platforms or subsea template, process them, and store oil until it can be offloaded onto a tanker or, less frequently, transported through a pipeline. FPSOs are preferred in frontier offshore regions as they are easy to install, and do not require a local pipeline infrastructure to export oil. FPSOs can be a conversion of an oil tanker or can be a vessel built specially for the application. A vessel used only to store oil is referred to as a floating storage and offloading (FSO) vessel.

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.[31] 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.[32]

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.[33] 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, the USS Gerald R. Ford was described as the "pre-commissioning unit (PCU) Gerald R. Ford" prior to her commissioning in 2017.[34] [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".[35] 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.)
  • Star Wars – The Galactic Empire sometimes uses the prefix ISD for Imperial Star Destroyer.
  • 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).
  • Firefly – Vessels in the Union of Allied Planets fleet are given the prefix "IAV", for Interstellar Alliance Vessel.
  • Wing Commander – The Terran Confederation uses TCS (Terran Confederation Ship) for its vessels.
  • HaloUnited 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"[36] 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 former opponents, 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.
  • The Moon is a Harsh Mistress – The Federated Nations use "FNS", presumably meaning "Federated Nations Ship".
  • 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 isn't 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 - A variety of 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."
