The Type 401 Rhein-class tender was a class of tender ships which was laid down in 1958, christened in 1959 and put into service in 1961 and served as a support unit for the 3rd Schnellboot Squadron until they were decommissioned by 1992. A total of eight ships of this class were built, in addition to the ships Rhine, the Elbe, Main, Neckar, Ruhr, Weser, Werra and Danube.
Tenders are used as supply and command ships and to supply combat units (FACs, anti-mine ships, submarines) with everything they need at sea. Long endurance at sea are only possible with these mother ships. The tenders take care of the supply of fuel, water and provisions, they also provide workshops, spare parts and tools as well as an infirmary with an operating theater for crews.
After decommissioning, four of the ships were scrapped, three sold to Turkey and one to Greece.
The Type 402 Mosel-class tender consists of three ships (Mosel, Isar, Saar) which are used to supply minesweepers.
The Type 403 Lahn-class tender are used to supply submarines with two ships of this subclass, Lahn and Lech.
Depending on the purpose (FAC or minesweeper tender), different drive concepts were used (diesel-electric drive or diesel engines).
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.
The Finnish Navy is one of the branches of the Finnish Defence Forces. The navy employs 2,300 people and about 4,300 conscripts are trained each year. Finnish Navy vessels are given the ship prefix "FNS", short for "Finnish Navy ship", but this is not used in Finnish language contexts. The Finnish Navy also includes coastal forces and coastal artillery.
A submarine tender is a type of depot ship that supplies and supports submarines.
A diesel–electric transmission, or diesel–electric powertrain is a transmission system for vehicles powered by diesel engines in road, rail, and marine transport. Diesel–electric transmission is based on petrol–electric transmission, a very similar transmission system used for petrol engines.
The Ton class were coastal minesweepers built in the 1950s for the Royal Navy, but also used by other navies such as the South African Navy and the Royal Australian Navy. They were intended to meet the threat of seabed mines laid in shallow coastal waters, rivers, ports and harbours, a task for which the existing ocean-going minesweepers of the Algerine-class were not suited.
The Type 760Westerwald-classreplenishment ship was a class of two replenishment ships of the German Navy. They are commissioned from 1967 to 2010. Their main task was to transport ammunition and material for warships at sea.
The 3"/50 caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1890 through the 1990s on a variety of combatant and transport ship classes.
The Type 925 Dajiang with NATO reporting name Dajiang, or 大江 in Chinese, meaning Great River, is a type of naval auxiliary ship belonging to the People's Republic of China. Each ship is usually equipped with up to two Type 7103 DSRV class Deep Submergence Rescue Vehicles (DSRVs). The ship is designed to replace the first People's Liberation Army Navy (PLAN) submarine tender PLANS Mount Tai, and the lead ship of the Dajiang class is the Changxingdao. The Type 925 is a submarine tender that can also be used as a submarine rescue ship, and hence, it is designated as a submarine support ship by Chinese.
Auxiliary motor minesweepers were small wood-hulled minesweepers commissioned by the United States Navy for service during World War II. The vessels were numbered, but unnamed. The auxiliary motor minesweepers were originally designated yard minesweepers (YMS) and kept the abbreviation YMS after being re-designated. The type proved successful and eventually became the basis for the AMS type of United States Navy minesweeper.
Allied Forces Baltic Approaches (BALTAP) was a Principal Subordinate Command (PSC) of the NATO Military Command Structure, with responsibility for the Baltic Sea area.

Z51 was the only ship of the Type 1942 destroyer class built for the Kriegsmarine. She was the only destroyer built by the Kriegsmarine to use diesel fuel, which would have given it a longer range and readier access to refueling compared to fuel oil. The Type 1942 destroyer class went through a long period of development, including four total designs. Z51 was ordered on 25 November 1942, and launched on 2 October 1944, far before being finished, likely to clear her slipway for U-boat construction. She was left floating outside Bremen and was sunk in an air raid on 21 March 1945. Germany attempted to communicate the plans for the Type 1942 destroyer to its ally the Empire of Japan using a submarine, U-234, however Germany surrendered before the submarine reached Japan. Z51 was broken up between 1948 and 1949.
