The Turkish Navy's Preveze (Type 209/1400)-class diesel electric submarine (SSK) mid-life upgrade (MLU) programme has achieved a new milestone with the successful completion of the critical design phase.

Turkey's Presidency of Defense Industries (SSB) approved the critical design phase following the successful completion of sea acceptance trials of the inertial navigation system, salinity-depth-density measurement and cold-water systems, and static inverters in mid-February, according to an announcement by Turkish company STM.

STM said the sea trials of the four subsystems were required to be completed before the critical design phase could be successfully concluded.

At the same time, the platform integration of the MÜREN combat management system (CMS) onboard first-of-class TCG Preveze has also been completed, STM added.

The Preveze-class MLU programme includes the upgrade of the first four submarines in the class: Preveze (S-353), TCG Sakarya (S-354), TCG 18 Mart (S-355), and TCG Anafartalar
