A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied greatly.
The Agosta-class submarine is a class of diesel-electric fast-attack submarine developed and constructed by the French DCNS in the 1970s to succeed the Daphné-class submarines. The submarines have served in the French Navy as well as exported to the navies of Spain and Pakistan. It also used by Royal Malaysian Navy for the training purpose. They were replaced in French service by the Rubis-class nuclear attack submarines but are still in active service with the navies of Spain and Pakistan. The French Navy grouped this model of submarine in their most capable class as an océanique, meaning "ocean-going."
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern types of ships below a corvette are coastal patrol craft, missile boat and fast attack craft. In modern terms, a corvette is typically between 500 tons and 2,000 tons, although recent designs may approach 3,000 tons, which might instead be considered a small frigate.
The Royal Canadian Navy is the naval force of Canada. The RCN is one of three environmental commands within the Canadian Armed Forces. As of 2021, the RCN operates 12 frigates, four attack submarines, 12 coastal defence vessels, eight patrol class training vessels, two offshore patrol vessels, and several auxiliary vessels. The RCN consists of 8,570 Regular Force and 4,111 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Craig Baines is the current commander of the Royal Canadian Navy and chief of the Naval Staff.
Naval Group is a major French industrial group specialized in naval defense design, development and construction. Its headquarters are located in Paris.
The Republic of Singapore Navy (RSN) is the naval service branch of the Singapore Armed Forces (SAF) responsible for the defence of Singapore against sea-borne threats and protection of its sea lines of communications. The service was formally established in 1967 and has since undergone a substantial modernisation.
The Royal Malaysian Navy is the naval arm of the Malaysian Armed Forces. RMN is the main agency responsible for the country's maritime surveillance and defense operations. RMN's area of operation consists of 603,210 square kilometers covering the country's coastal areas and Exclusive Economic Zones (EEZ). RMN also bears the responsibility of controlling the country's main Sea Lines of Communications (SLOC) such as the Straits of Malacca and the Straits of Singapore and also monitors national interests in areas with overlapping claims such as in Spratly.
The River class was a class of 151 frigates launched between 1941 and 1944 for use as anti-submarine convoy escorts in the North Atlantic. The majority served with the Royal Navy (RN) and Royal Canadian Navy (RCN), with some serving in the other Allied navies: the Royal Australian Navy (RAN), the Free French Navy (FFN), the Royal Netherlands Navy and, post-war, the South African Navy (SAN).
A submarine chaser or subchaser is a small naval vessel that is specifically intended for anti-submarine warfare. Many of the American submarine chasers used in World War I found their way to Allied nations by way of Lend-Lease in World War II.
The Algerine-class minesweeper was a large group of minesweepers built for the Royal Navy (RN) and the Royal Canadian Navy (RCN) during the Second World War. 110 ships of the class were launched between 1942 and 1944.
The Scorpène-class submarines are a class of diesel-electric attack submarines jointly developed by the French Naval Group and the Spanish company Navantia. It features diesel propulsion and an additional air-independent propulsion (AIP). It is now marketed as the Scorpène 2000.
The Kobben class is a customized version of the German Type 205 submarine. Fifteen vessels of this class were built for use by the Royal Norwegian Navy in the 1960s. The class later saw service with Denmark and Poland. The boats have since been withdrawn from service in the Norwegian and Danish navies. The Polish Navy still operates two Kobben-class submarines as of 2020, but 2021 may see these final two boats retired.
The British U-class submarines were a class of 49 small submarines built just before and during the Second World War. The class is sometimes known as the Undine class, after the first submarine built. A further development was the British V-class submarine of 1942.
The Royal Navy Submarine Service is one of the five fighting arms of the Royal Navy. It is sometimes known as the Silent Service, as submarines are generally required to operate undetected.
The Flower class comprised five sub-classes of sloops built under the Emergency War Programme for the Royal Navy during World War I, all of which were named after various flowers. They were popularly known as the "herbaceous borders", in humorous reference to a well-known adage about the Royal Navy, as well as to a type of garden border popular in the United Kingdom.
HMS Tantalus was a British submarine of the third group of the T class. She was built as P318 by Vickers Armstrong, Barrow, and launched on 24 February 1943. So far she has been the only ship of the Royal Navy to bear the name Tantalus, after the mythological Tantalus, son of Zeus.
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some—known in the Royal Navy as "Admiralty trawlers"— were purpose-built to naval specifications, others adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.
KD Tunku Abdul Rahman is a Scorpène-class submarine built for the Royal Malaysian Navy by Naval Group, formerly known as DCNS in Cherbourg, France and Navantia in Cartagena, Spain.
Two submarines of the French Navy have borne the name Ouessant:
