Mid-Life Modernisation For Preveze Class Submarines

One of the four Preveze class submarines which will receive a mid-life-modernisation.

The Undersecretariat for Defence Industries (UDI) has issued a request for proposal for the mid-life modernisation work on Preveze class submarines.

UDI has issued the RfP in Turkish as it is local development project.

UDI previously managed the upgrade of two Type 209/1200 class submarines TCG Doğanay and TCG Dolunay. The contract was awarded to STM and the project included renewal of electronic support, attack and search periscopes and inertial navigation systems.

although the scope of mid-life modernisation work on Preveze class submarines has not been published yet, it is safe to assume it will involve the upgrade of the electronic systems maybe even the combat management system. If so then the CMS developed for Preveze class submarines may work as a prototype for the future CMS of the Reis (Type 212) class submarines.

Turkish Navy operates 12 Type 209 submarines. The oldest 5 of them are Ay class submarines. The reminder are Type 209/1400 class submarines. The first batch of four is known as Preveze class and the last four as Gür class. The main difference between these are the later have a new fire control system integrated with the sonar, new data links and improved target acquisition and tracking capabilities.
