TCG Yıldıray, TCG Doğanay, and TCG Dolunay are the first modern submarines build in Turkey. The others were build in Germany. The electronic systems have been modernized.
In March 2011 a new modernization project for the Ay class has started. According to the plan the newest two boats, TCG Doğanay and TCG Dolunay were to receive an extensive modernization. The periscope, ESM / ECM and communication system of the existing boats would be upgraded. In order to keep costs down a modern purpose-built Underwater Command and Control System integration was not planned. These old boats are going to get some might punch though. It is planned to modify four of the torpedo tubes so that they can use Mk48 ADCAP Mod6 AT heavy weight torpedoes.
TCG Saldıray was decommissioned on 14 November 2014.
TCG Atılay was decommissioned on 30 November 2016.
