Rolls-Royce Marine Power Operations at Derby was the centre for design and manufacture of the UK's submarine reactors, and remains so today. The Ministry of Defence 's Vulcan Naval Reactor Test Establishment (NRTE) , at Dounreay , tested each reactor core design prior to its installation in nuclear submarines.
The sub remained mostly inactive until 2 February 1970, when she began an overhaul in drydock and modifications to prepare her for Project SURPASS, researching the use of polymer mixed with fresh water to reduce drag, [23] [25] sponsored by the Naval Ship Research and Development Center at Carderock, Maryland. The ship left drydock on 16 April ...
All electronic and weapon systems (including the C4I system) will be of Turkish production. [citation needed] On 1 July 2011, the 2 billion euros order for six U 214 submarine material packages placed with ThyssenKrupp Marine Systems by Turkey entered into force with receipt of the advance payment. This enabled ThyssenKrupp to begin executing ...
The Type 209 (German: U-Boot-Klasse 209) is a range of diesel-electric attack submarines developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany.Five class variants (Types 209/1100, 209/1200, 209/1300, 209/1400 and 209/1500), including modifications thereof, have been successfully exported to 15 countries, with 68 submarines being built and commissioned to five different ...
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 Type 212 is the first fuel cell propulsion system equipped submarine series. [8] [9]
The Gotland-class submarines of the Swedish Navy are modern diesel-electric submarines, which were designed and built by the Kockums shipyard in Sweden. They are the first submarines in the world to feature a Stirling engine air-independent propulsion (AIP) system, which extends their underwater endurance from a few days to weeks. [2]

Previously special forces used torpedo tubes and handheld propulsion systems. The vessel also has the ability to use the MdCN ground attack cruise missile in its submarine-borne version, launched via torpedo tube. [citation needed] It is said to be ten times quieter than the previous generation Rubis-class nuclear attack submarine. [11]
