STM won the submarine modernization tender in 2016. Within the scope of Agosta 90B Submarine Modernization Project, the vessel has been upgraded with “an Integrated Underwater Command and Control System (IUCCS &C2IS), a Weapon Control System (WCS), Sonar Systems, Periscopes (Attack and Search), an Electronic Warfare, Radar and Ship Data Distribution System, a STMDENGİZ Electronic Chart Display and Information System, Converters, a Steering System and a Chilled Water System.”

The modernization of the two other submarines in the Agosta 90B Submarine Modernization Project, is underway as planned, the Turkish firm emphasized.

STM worked with DNV, a member of the International Association of Classification Societies (IACS), throughout the project, and all the modifications performed onboard and on pressure hull were certified by DNV as well.
