On November 22, Turkish Minister of Industry and Technology Mustafa Varank visited the modernized S-353 Preveze submarine in the Golcuk naval shipyard and inspected MÜREN The progress of the battle management system project, and simulated torpedo battles with the new system. He confirmed that MüREN CMS has been installed on a number of 209/1400 TN (Preveze) class submarines. After completing the sea acceptance test, the submarine equipped with the MÜREN combat management system will return to the combat sequence in 2022.
The Turks are currently transforming the S-353 Preveze submarine under the MÜREN-PREVEZE project. The submarine is equipped with the Turkish domestic MÜREN battle management system, based on the ADVENT system developed by HAVELSAN and ARMERKOM and ADVENT's Link 11 and Link 22. , JREAP (Joint Range Extension Application Protocol), multiple tactical data link systems and WAIS (Warship Automatic Identification System) subsystems, enabling it to process more information than existing systems, and the equipment is fully localized, including 20 Different sensors, navigation systems and weapon systems. Havelsan has developed submarine-related systems such as integrated combat management, torpedo launch control and satellite communications, which can perform tasks such as sonar signal processing, command and control, fire control and ship navigation. Turkish company Meteksan Defense developed a submarine integrated sonar package. This class of submarines began to be rebuilt in 2017. Meteksan Savunma joined the project as a subcontractor in July 2018, responsible for analog signal conversion, digital signal processing and hardware and software transformation, and replaced advanced display consoles. Currently, 4 submarines of this class are planned.
After the transformation is completed, the Preveze class submarine will be able to launch the German DM2A4 Sea Hake heavy torpedo, and the local AKYA heavy torpedo to replace the Mk24 Sea Hake torpedo. The DM2A4 torpedo is 6.62m long and the PBX warhead weighs 260kg. The fuze includes proximity (magnetic induction) and contact detonation modes. The maximum speed exceeds 50 knots and the maximum range is 90 kilometers. It has a range of 50km against general medium/high-speed maneuvering targets. The length of the Akaya AKYA heavy torpedo is 7 meters, the diameter is 533 mm, and the weight is 1.2 tons. The weight of the warhead is about 350-380 kg. It adopts fiber optic line guidance and active and passive sonar guidance systems. The power system may be silver oxide -Zinc battery battery system + dual counter-rotating propellers, cruising speed of 40 knots, range of 15 kilometers. Two sets of 6-unit anti-torpedo decoy launching tubes may also be installed on the side of the hull.
