The Turkish Navy’s Preveze-class submarine mid-life modernisation project (Preveze-YÖM) has reached a new milestone. These trials were performed before the completion of the design stages as per the contract. The sea acceptance trials of the inertial navigation system, CTD probes, chilled water system and static inverters have been concluded as part of the project, which is being completed under the guidance of the Presidency of Defence Industries (SSB). SBB also approved the project’s critical design phase. Meanwhile, the Turkish Navy worked on the completion of the platform incorporation of the MÜREN combat management system.
The Preveze-Class Submarines Mid-Life Modernisation Project (PMMP) includes the upgrade of four Preveze-class submarines, TCG Preveze (S-353), TCG Sakarya (S-354), TCG 18 Mart (S-355) and TCG Anafartalar (S-356). Under this upgrade project, inertial navigation system, salinity-depth-density measurement system, floating antenna, satellite communication mast, assault and navigation periscope system will be acquired by SBB. Upgrade work is being performed by STM-ASELSAN-HAVELSAN, in collaboration with ASFAT. The procurement activities will also cover cooled water system, emergency underwater communication system, static converter and air freshening system.
In the modernisation process, it is planned to carry out the procurement activities of Inertial Navigation System, Salinity-Depth-Density Measurement System, Floating Antenna, Satellite Communication Mast, Assault and Navigation Periscope System, Emergency Underwater Communication System, Cooled Water System, Static Converter and Air Freshening System by us, as STM. In addition to procurement activities, platform integration activities of all products supplied by STM-ASELSAN-HAVELSAN and ASFAT Partnership are also carried out by us.
The largest operator of the Type 209 is the Turkish Navy which operates six Type 209/1200 submarines (commissioned between 1976 and 1989) and eight Type 209/1400 submarines (commissioned between 1994 and 2007). At present, the Turkish Navy is also the largest operator of German designed submarines in the world. The Type 209 is a class of diesel-electric attack submarine developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany.The class is exclusively designed for export market. Despite not being operated by the German Navy, five variants of the class (209/1100, 209/1200, 209/1300, 209/1400 and 209/1500) have been successfully exported to 13 countries, with 61 submarines being built and commissioned between 1971 and 2008.
