Octopus class was the NATO name for a type of anti-mine vehicle of the People's Navy of the GDR , which was in use between 1957 and 1976. In the People's Navy, the ships were called MLR-Schiff (mine-laying and clearing ship) and project number 15. As the successor to the MLR-2000 of the Habicht class , they were also sometimes referred to as the MLR-3000 .
Construction and history
The order for the development of this type of ship was given before the official founding of the Volksmarine and was carried out in 1953 by its predecessor, the so-called Volkspolizei-See. It was until 1958 ten ships in the state-owned enterprise Peene-Werft completed. Of these units, seven were decommissioned between 1972 and 1973 and later scrapped. The remaining were used for training purposes until 1976.
technical description
Drive, sensors and devices
The ships had a welded steel hull. Two diesel engines of the type 6KVD 43A developed by VEB Dieselmotorenwerk Rostock with a total of 2046 kW were used as propulsion , which could accelerate the ships of this class to around 16.5 knots via two screws.
The ships were equipped with a navigation radar device of the type KSA-5, which had been developed in the GDR.
A Tamir-11 sonar, produced in the Soviet Union since 1950, was installed on the ships to search for underwater targets. It already had a screen to display the acoustic information.
All ships were equipped with transmitters and receivers for the Russian friend / foe recognition system of the "nichrome" type to identify friendly ships or aircraft and to confirm their own identity to the allies .
Armament
The main armament of the ships of this class consisted of the Soviet system 90K, which was composed of a turret with a single mount gun in caliber 85 mm L / 52 and was placed on the forecastle .
Several were used for anti-aircraft twin guns of the type 2M-3 , equipped with 25 mm machine guns that were amidships. This type of weapon was developed in the Soviet Union as early as 1950 and could fire around 450 rounds per minute at targets up to 3000 meters away. It had a straightening angle of up to 85 °.
If necessary, have the back deck mines are deposited into the sea or on the BMB-2-thrower depth charges are fired to combat submarines.
For clearing mines could over the stern Räumgeschirr to hawsers are towed behind at the ships moored mines or to combat so-called hollow rods with the aid of simple types of underground mines.
Current Status
There are no more ships of this type in use.
