First Upgraded PREVEZE Class Submarine, TCG Preveze, Will Return to the Turkish Fleet by the End of March 2022

Within the scope of the MÜREN-PREVEZE Combat Management System (CMS) Modernization Project, first upgraded PREVEZE Class Submarine, TCG Preveze (S-353), will be handed over to the Turkish Naval Forces (TNF) by the end of March 2022 following the completion of currently (February 9, 2022) ongoing its final sea trials, which aimed to prove that in previously uncompleted tests during SAT Phase (such as sea condition, auxiliary platform planning, etc.) the prerequisites are provided. Before sea trials, final checks of the submarine hull were performed at the Gölcük Naval Shipyard dock in late January 2022.

Thanks to its improved capabilities, the diesel-electric powered TCG Preveze Submarine proved that it was ready for duty with its performance during the Sea Acceptance Tests (SAT) and the Live Firing Tests (fired several DM2A4 Training Torpedoes via MÜREN CMS) carried out during December 2021 and January 2022. The first Sea Acceptance Test with the TCG Preveze Submarine was supposed to be performed on September 27, 2021, during the 483rd anniversary of the TNF’s Preveza Naval Victory, but this schedule could not be met due to the delays experienced in the program.

The contract of the MÜREN-PREVEZE Modernization Project was signed on August 1, 2017, and carried out by the Main Contractor TÜBİTAK BİLGEM. Under the project, the obsolete ISUS-83/2 Combat Management System with 4 Operator Consoles onboard the TCG Preveze Submarine was replaced with the new generation and fully integrated MÜREN CMS with 5 Operator Consoles, and 20 different sensors and the navigation system were also upgraded. Within the scope of MÜREN-PREVEZE Project, for each PREVEZE Class Submarine YALTES, TÜBİTAK BİLGEM subcontractor, delivers a total of 4 water-cooled (chilled water) Electronic Cabinets in two different sizes for data and video related electronic components (long ones EC-1 and EC-2) and power units (short ones EC-3 and EC-4) as well as 2 Weapon Control Cabinets (for torpedo firing) and 5 water-cooled MOCs. YALTES will complete deliveries of the CMS equipment for the 2nd, 3rd and 4th submarines in 2022.
