The Archer class submarines are the newest class of diesel-electric submarines in active service with the Republic of Singapore Navy (RSN). Originally launched as the Swedish Navy Västergötland class submarines HMS Hälsingland and HMS Västergötland in 1986 and 1987, the two submarines were sold to Singapore in November 2005 and relaunched in June 2009 and October 2010 respectively after extensive modernisation by Kockums, which included a refit to Södermanland class standards, the insertion of a new hull section with an air independent propulsion system, and additional climatisation for use in tropical waters.Challenger-class submarine
The Challenger class is one of the submarine classes of the Singapore Navy. They are extensively modernized versions of ex-Sjöormen class submarines. Challenger and Centurion were retired in 2015.Coastal submarine
A coastal submarine or littoral submarine is a small, maneuverable submarine with shallow draft well suited to navigation of coastal channels and harbors. Although size is not precisely defined, coastal submarines are larger than midget submarines, but smaller than sea-going submarines designed for longer patrols on the open ocean. Space limitations aboard coastal submarines restrict fuel availability for distant travel, food availability for extended patrol duration, and number of weapons carried. Within those limitations, however, coastal submarines may be able to reach areas inaccessible to larger submarines, and be more difficult to detect.Cruise missile submarine
A cruise missile submarine is a submarine that carries and launches cruise missiles (SLCMs) as its primary armament. Cruise missiles and dedicated anti-ship missiles greatly enhance a vessel's ability to attack surface combatants. Torpedoes are a more stealthy option, but missiles give a much longer stand-off range, as well as the ability to engage multiple targets on different headings at the same time. Many cruise missile submarines retain the capability to deploy nuclear warheads on their missiles, but they are considered distinct from ballistic missile submarines due to the substantial differences between the two weapons systems' characteristics.
Originally early designs of cruise missile submarines had to surface to launch their missiles, while later designs could do so underwater via dedicated vertical launching system (VLS) tubes. Many modern attack submarines can launch cruise missiles (and dedicated anti-ship missiles) from their torpedo tubes while some designs also incorporate a small number of VLS canisters, giving some significant overlap between cruise missile submarines and traditional attack submarines. Nonetheless, vessels classified as attack submarines still use torpedoes as their main armament and have a more multi-role mission profile due to their greater speed and maneuverability, in contrast to cruise missile submarines which are typically larger slower boats focused on the long distance surface strike role.
The United States Navy's hull classification symbols for cruise missile submarines are SSG and SSGN – the SS denotes submarine, the G denotes guided missile, and the N denotes that the submarine is nuclear-powered.Kashalot-class submarine
The Project 1910 Kashalot class submarine (NATO reporting name: Uniform) is a class of research and special operations submarine constructed by the Soviet Union during the late 1970s and early 1980s.Two boats of the class were constructed, AS-13 and AS-15, with the first boat of the class being laid down in 1977 and commissioned in 1986, the second being laid down in 1983 but not commissioned until 1991. A third class boat, AS-12, reached the fitting-out stage before being cancelled in 1998.Displacing 1,580 tons submerged, the Kashalot class was constructed using a single titanium hull design, and is powered by a nuclear reactor; they were the first Soviet nuclear-powered submarines to have a single hull. The boats each have a crew of 36 officers and men.Nahang-class submarine
The Nahang class (Persian: نهنگ lit. Whale) is an Iranian-made class of small submarines.Naval ship
A naval ship is a military ship (or sometimes boat, depending on classification) used by a navy. Naval ships are differentiated from civilian ships by construction and purpose. Generally, naval ships are damage resilient and armed with weapon systems, though armament on troop transports is light or non-existent.
Naval ships designed primarily for naval warfare are termed warships, as opposed to support (auxiliary ships) or shipyard operations.Oyashio-class submarine
The Oyashio class is a series of Japanese diesel-electric attack submarines operated by the JMSDF. The submarines entered service in the late 1990s. The submarines are larger than the earlier Harushio class, to provide space for a flank sonar array.Paltus-class submarine
The Paltus Class submarine is a Russian special purpose mini-submarine of project 1851.1. Two boats were completed "AS-21" and "AS-35" as a follow up of the single "X-Ray" class boat "AS-23" (Project 1851). They are both part of the 29th special submarine squadron at Olenya Guba.
The surface displacement was approximately 300 tons with a length of 98ft (30m). The propulsion was nuclear power with the operating depth was in excess of 3800ft ( 1000m ). The designer , according to Polmar was Sergei Bavilin who had designed the earlier diesel electric Project 865/Piranya small submarine of similar dimensionsRomeo-class submarine
The Project 633 class (known in the West by its NATO reporting name as the Romeo class) is a class of Soviet diesel-electric submarine, built between 1957 and 1961. A Chinese variant - Type 033 - was built in China from 1962 to 1984.Rubis-class submarine
The Rubis type is a first class generation nuclear attack submarine of the French Navy. The class comprises six vessels and they are the most compact nuclear attack submarines to date. All submarines of the class (except for Casabianca) are named after gemstones.Sauro-class submarine
The Nazario Sauro class are submarines operated by the Italian Navy. All boats were built by Fincantieri in Monfalcone.Seawolf-class submarine
The Seawolf class is a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy. The class was the intended successor to the Los Angeles class, and design work began in 1983. A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines. The end of the Cold War and budget constraints led to the cancellation of any further additions to the fleet in 1995, leaving the Seawolf class limited to just three boats. This, in turn, led to the design of the smaller Virginia class. The Seawolf class cost about $3 billion per unit ($3.5 billion for USS Jimmy Carter), making it the most expensive SSN submarine and second most expensive submarine ever, after the French SSBN Triomphant class.Sierra-class submarine
The Sierra class, Soviet designations Project 945 Barrakuda and Project 945A Kondor, (NATO reporting names Sierra I and Sierra II respectively), is a class of nuclear-powered attack submarines intended for the Soviet Navy and currently in service with the Russian Navy.
The class is unique due to its light and strong titanium pressure hull which enables the submarines of the class to dive to greater depths, reduce the level of radiated noise and increase resistance to torpedo attacks. It is powered by a single OK-650 pressurized water reactor.
The upgraded version, the Sierra II class was specifically developed for search and destroy missions against US nuclear submarines. It has a smaller turning circle than any other modern submarine, with speeds and diving depth greater than its American counterparts. It has also improved quieting and sonar.Sinpo-class submarine
The Sinpo class submarine, also called the Gorae ("whale") or Pongdae class, is a new class of submarine produced in North Korea. Only one submarine has been observed in service. It is the largest submarine designed and built for the Korean People's Navy.Triomphant-class submarine
The Triomphant class of ballistic missile submarines of the French Navy is the active lead boat class of four boats that entered service in 1997, 1999, 2004, and 2010. These four superseded the older Redoutable class, and they provide the ocean-based component (the Force océanique stratégique) of France's nuclear deterrent strike force, the Force de Frappe. Their home port is Île Longue, Brest, Western Brittany.Västergötland-class submarine
The Västergötland class of diesel-electric submarines was introduced in 1987 by the Swedish Navy.Yono-class submarine
The Yono-class submarine (also as Yugo class) is a class of North Korean miniature submarines, produced for domestic use as well as for export. Also referred to as the Yeono class, these submarines displace 130 tons, significantly less than North Korea's larger 1,800-ton Romeo-class submarines. As of May 2010, North Korea is reported to operate ten of these submarines.Yugo-class submarine
The Yugo class submarine is a class of four midget submarines used primarily for infiltration and espionage by North Korea. The class is so named because it was built to plans supplied to North Korea by Yugoslavia in 1965.
