The modernization project comprising renewal of Electronic Support, Attack and Search Periscopes and Inertial Navigation Systems
has been carried out by STM as the main contractor
and applied successfully on TCG DOĞANAY (S-351) and TCG DOLUNAY (S-352), AY- Class submarines.

The modernization project led by the STM remains significant in a way that for the first time in the history of Turkey, a civilian company has been appointed as a main-contractor of a navy submarine project.
