The Type 212A is a class of diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German Navy, and the Italian Navy where it is known as the Todaro class. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton-exchange membrane (PEM) compressed hydrogen fuel cells. The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free and virtually undetectable.
The Collins-class submarines are Australian-built diesel-electric submarines operated by the Royal Australian Navy (RAN). The Collins class takes its name from Australian Vice Admiral John Augustine Collins; each of the six submarines is named after significant RAN personnel who distinguished themselves in action during World War II. The six vessels were the first submarines built in Australia, prompting widespread improvements in Australian industry and delivering a sovereign sustainment/maintenance capability.
The Type 540 Gal-class submarine is a slightly modified variant of the German HDW Type 206 submarine class, modified for Israeli requirements. The Gal class submarines were built to Israeli specifications as the Vickers Type 540 at the Vickers shipyards in Barrow-in-Furness in the UK rather than Germany for political reasons. "Gal" was the name of the son of Abraham (Ivan) Dror, 3rd commander of the squadron and head of the project.
ORP Bielik, formerly HNoMS Svenner (S309), was one of four Kobben-class submarines in service with the Polish Navy. The vessel and its sister ships were built in the period 1964–1967 by Rheinstahl Nordseewerke GmbH in Emden, West Germany for the Royal Norwegian Navy. The Kobben-class submarines were given to Poland in the 2002–2004 period after having been replaced by Ula-class submarines in Norway. Before entering active Polish service the boat was modified in Gdańsk. She was decommissioned in December 2021 alongside her sister Sęp, with the decommissioning marking the end of active service for the Kobben-class submarines.
Howaldtswerke-Deutsche Werft is a German shipbuilding company, headquartered in Kiel. It is part of the ThyssenKrupp Marine Systems (TKMS) group, owned by ThyssenKrupp. The Howaldtswerke shipyard was founded in Kiel in 1838 and merged with Hamburg-based Deutsche Werft to form Howaldtswerke-Deutsche Werft (HDW) in 1968. The company's shipyard was formerly used by Friedrich Krupp Germaniawerft until the end of World War II.
The Type 214 is a class of diesel–electric submarines developed exclusively for export by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class combines the design principles of the Type 209 submarine family and the features of the Type 212A submarine. However, as an export design, it lacks some of the classified technologies of the Type 212 such as the non-magnetic steel hull that makes it difficult to detect using a magnetic anomaly detector.
The G7e torpedo was the standard electric torpedo used by the German Kriegsmarine submarines in World War II. It came in 20 different versions, with the initial model G7e(TII) in service at the outbreak of the war. Due to several problems, leading to the German "Torpedokrise" which lasted until the end of 1941, the improved G7e(TIII) took over as the standard electric torpedo used by German U-boats for the rest of the war. G7e torpedoes measured 533.4 mm (21.00 in) in diameter and about 7.2 m (24 ft) in length. Depending on the type, the warhead contained a main charge of 250–280 kg (550–620 lb) of Schießwolle 36, a mixture of dipicrylamine and TNT. All were powered by 60–72 kW (80–100 hp) electric motors and lead-acid batteries which required onboard maintenance to maintain their functionality.
The Shishumar-class submarines are diesel-electric attack submarines, currently in active service with the Indian Navy. These submarines are an Indian variant of the Type 209 submarines developed by the German yard Howaldtswerke-Deutsche Werft under the internal designation "Type 1500". The first two vessels were built by HDW at Kiel, Germany, while the remainder were built by Mazagon Dock Limited, at Mumbai, India, under a technology transfer agreement. The submarines were commissioned between 1986 and 1994. These submarines have a displacement of 1,660 tons when surfaced, a speed of 22 knots, and a complement of 40 including eight officers.
The Type 205 was a class of German diesel-electric submarines. They were single-hull vessels optimized for the use in the shallow Baltic Sea. The Type 205 is a direct evolution of the Type 201 class with lengthened hull, new machinery and sensors. The biggest difference though is that ST-52 steel is used for the pressure hull since the Type 201's non-magnetic steel proved to be problematic. Type 206, the follow-on class, finally succeeded with non-magnetic steel hulls.
Nordseewerke Emden GmbH was a shipbuilding company, located in the Emden Harbor of the north German city of Emden. Founded in 1903, shipbuilding ended in 2010, and the company was taken over by the Schaaf Industrie AG, which among other products, makes components for off-shore systems.
The Type 202 submarine was a short lived class of German submarines. Design of these very small submarines started in 1957 by Ingenieurkontor Lübeck (IKL). It was intended to build 40 Type 202 mini submarines with a six-man crew but technical difficulties and doubts about their usefulness reduced them to three, and of those three for trials, to be further reduced to two. The boats were in service only a few months and were scrapped shortly after.
The Type 201 was Germany's first U-boat class built after World War II.
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 operated two Kobben-class submarines until 2021.
U-32 (S182) is a Type 212A submarine of the German Navy, the second of her class to enter service.
U-31 (S181) is a Type 212A submarine of the German Navy, and the lead ship of her class.
The Type 209 is a range of diesel-electric attack submarines developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. Five class variants, including modifications thereof, have been successfully exported to 15 countries, with 68 submarines being built and commissioned to five different variants between 1971 and 2021. More boats have been built to modified designs.
The Heroine class are a variant of the Type 209 diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft (HDW) of Germany, currently in service with the South African Navy. The class is composed of three vessels.
SAS Charlotte Maxeke (S102) is a Heroine-class submarine, a variant of the Type 209 diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft (HDW) of Germany, currently in service with the South African Navy. She is named after Charlotte Maxeke, a South African religious leader and political activist.
SAS Queen Modjadji is a variant of the Type 209 diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft (HDW) of Germany, currently in service with the South African Navy. She was named after the South African Rain Queen on 14 March 2007 by the ship's sponsor, Mrs. Rita Ndzanga, at a ceremony in Emden, Germany.
