Improved and larger successors of ATILAY class submarines. They are being built locally with some German assistance.
Diving depth is 250 m. The endurance of these boats is very good. Between 24 October 1997 and 3 February 1998 PREVEZE sailed alone from Turkey to Malaysia and back in order to show flag and to promote Turkey's ship building capabilities at the LIMA 97 Defense Exhibition.
Each submarine has one Mark 76 Attack and one Mark 76 Search periscope manufactured by Kollmorgen.
In April 1999 BAe (STN Atlas) DM2A4 heavy torpedo (40+ training torpedoes) was selected for cost of $40 million
A contract for a second batch of PREVEZE class was signed between the Turkish Navy and HDW at 22 July 1998. The construction of S-357 GÜR was started two days later. These last four boats are called GÜR class by Turkish Navy.
