The 18 boats of the Lindau class ( class 320 ) were originally manufactured as coast minesweepers 55 at the Burmester shipyard in Bremen-Burg and put into service between 1958 and 1960. Later, a majority of the boats were converted to class 331 mine hunters (with subclasses 331A and 331B) and a smaller part to class 351 hollow bar boats .

history

Coastal Minesweepers (Class 320)

The Lindau class was the German version of the US Bluebird class that had been made a NATO unit type and adapted by various NATO member states . As a replica of this type, six boats were built in France between 1959 and 1960 as the Mercure type for the German Navy ( Vegesack class ).

The Lindau class, on the other hand, was changed slightly. B. to improve the stability a lower bridge structure and proven to be a very robust and versatile boat class. Both versions (mine hunter and hollow rod boat, see below) were successfully used during Operation South Flank in the Persian Gulf. The boats have been refitted and reclassified several times over the years. In the period from 1991 to 2000, all units of the class were decommissioned by the German Navy.

Mine hunting boats (Class 331)

Between 1970 and 1979, twelve of the boats were converted to mine hunting boats (initially two to subclass 331A and in the middle of the decade the remaining ten to subclass 331B). They were equipped with a mine-hunting sonar and two remote-controlled mine-hunting drones PAP 104, as well as the high-precision SYLEDIS navigation system. The tasks of class 331 were taken over by the ships of the Kulmbach class (class 333) after they were decommissioned by the German Navy .

Hollow bar steering boats (Class 351)

In 1979 the remaining six boats were equipped with the "Troika" system for steering hollow bar boats of the seal type and then designated as Class 351. When they were decommissioned in Germany, these were replaced by the units of the Ensdorf class (class 352).

Retirement and whereabouts

Most of the boats went into the service of friendly countries, two have been preserved in Germany (for details see below in the section on the individual boats).

technology

Since minesweepers are supposed to generate the smallest possible magnetic field, the Lindau- class boats were built from wood. Above the waterline, 3 layers with intermediate insulation are glued together. The first and third layers of mahogany are aligned parallel to the keel, the middle layer of teak diagonally. A fourth layer of oak was attached below the waterline. The frame structure consists of 118 transverse, 2 longitudinal and 20 structural frames made of wood, frame spacing 0.38 m. Mainly non-magnetic material was used for superstructures and installations.

drive

The drive was originally two Mercedes-Maybach-MD-871-16-cylinder V-engine with 2,000 horsepower, the two three-winged Escher-Wyss - pitch propeller drives.

Three MWM 3-cylinder diesels (type 518Dn / 5) with 220 V direct current generators and two MD 441s with 900 hp (clearing diesels) were installed in the minesweepers. Four of them were in the power plant, the fifth (1MWM 3-cylinder diesel) in the engine room. In the units converted into class 331A mine-hunting boats, which had two additional Schottel propellers , two electric diesels were removed and a Maybach V-8 diesel engine with 900 hp installed for the Schottel drive. Schottel propellers were later dispensed with in the 331B class.

Fuel bunker 42 m³, or 28 m³ after conversion. Range at 14 kn 900 nm.

 Germany

The boats got the names of German cities. They were stationed in the North Sea throughout their service life. As coast minesweepers they belonged to the 4th minesweeping squadron (4th MSG) with home port Wilhelmshaven and to the 6th minesweeping squadron (6th MSG) and the 8th minesweeping squadron (8th MSG) in Cuxhaven .

After the reconstruction, the mine hunting boats formed the 4th MSG, the hollow rod steering boats the 6th MSG. Both squadrons, which had merged for a few years in the late 1970s and early 1980s to form the North Sea mine defense squadron, were stationed in Wilhelmshaven. After the first MJ boats were decommissioned, the 4th MSG was dissolved and the remaining mine hunters also belonged to the 6th MSG in their final years under the German flag.

 Georgia

Georgia took over a class 331B boat, the former Minden , and had it converted into a patrol boat for the coast guard in Germany , including an Atlas Elektronik TRS (I-Band) search radar . It entered service on November 15, 1998 as Ayety (P 22). On August 13, 2008, during the Caucasus conflict , the ship was towed into the military part of the port of Poti and sunk there by Russian soldiers by detonation.

 Latvia

Latvia took over two boats of the 331B class with the complete mine-hunting equipment including the PAP104 drones, but only operated one boat, the former Völklingen . She was stationed as Namejs (M-03) in Liepāja (Libau) and was taken out of service in 2009. She has been used as a stationary school boat at the Liepāja Naval School since April 8, 2009 . Göttingen , which was also taken over , only served as a spare parts donor.

 Lithuania

Sūduvis (2007)

Like Latvia, the Lithuanian Navy took over two boats of the 331B class with all mine-hunting equipment including the PAP104 drones. Both boats were put into service here and stationed with the anti-mine squadron in Klaipėda (Memel) .

Like its Baltic neighbors, Estonia took over two boats with all the mine-hunting equipment including the PAP104 drones and also operated them as mine hunters. They were stationed in Tallinn .

 South Africa

South Africa took over all six Class 351 boats, which were designated as City Class. The contract to purchase the boats was signed on November 10, 2000. Four boats became part of the fleet, two of which only belonged to the reserve fleet. The home port was Simon's Town . The former Ulm and Konstanz only served as spare parts donors. The latter was used in the Red Lion maneuver on November 1, 2007 as a training target for frigates and was sunk by Exocet MM40 anti-ship missiles.

 Italy

The whereabouts of the Tübingen is an exception: it was sold in 1997 to an Italian private owner who converted it into a motor yacht. The ship's clock came into the possession of the Tübingen City Museum through a gift from Erich Stahn from Schwebheim. A model of the Tübingen in the extension of the Tübingen town hall on the first floor bears witness to the intensely cultivated Tübingen sponsorship .
