Tuzla-class patrol boat

The "Tuzla"-class New Type Patrol Boat (Turkish: "Yeni Tip Karakol Botu") is one of the patrol boat classes of the Turkish Navy. The "Tuzla" class, named after a district in Istanbul with the same name, have been designed by Dearsan Shipyards in order to meet the operational requirements of the Turkish Navy in littoral waters. These patrol boats conduct patrol, security and anti-submarine warfare (ASW) duties in or around harbors & coastal areas.
Development.
The contract signed between SSM and Dearsan on 23 August 2007 called for 16 New Type Patrol Boats to be constructed until 2015. Along with Dearsan, 204 domestic supplier firms are involved with the NTPB project as well as several foreign ones such as MTU or Oto Melara. The project is a first for the Turkish Navy and the Turkish military shipbuilding industry as there is a 67.5% domestic production percentage compared with 65% for the MILGEM.
As of February 2015, all 16 boats have been delivered to the Turkish Navy.
