G class frigate

G class is one of the frigate classes of the Turkish Navy. They are all modernized versions of ex-"Oliver Hazard Perry" class guided-missile frigates, mainly designed for air defense with a weapons configuration that is optimized for general warfare and capable enough to do most jobs adequately. A total of eight G-class frigates are currently operated by the Turkish Navy. They are named as TCG "Gaziantep" (F-490), TCG "Giresun" (F-491), TCG "Gemlik" (F-492), TCG "Gelibolu" (F-493), TCG "Gökçeada" (F-494), TCG "Gediz" (F-495), TCG "Gökova" (F-496) and TCG "Göksu" (F-497).

The Turkish Navy has commenced the modernization of its G class frigates with the GENESIS (Gemi Entegre Savaş İdare Sistemi) advanced combat management system which was indigenously developed in Turkey.

* A modern and reliable system;
* High performance;
* Open architecture;
* Capacity of watching more than 1000 tactical targets;
* Modern sensor data fusion;
* Automatic threat evaluation;
* Weapon engagement opportunities;
* Link-16/22 system integration

The modernization program also includes the addition of an 8-cell Mk-41 VLS for Evolved Sea Sparrow, enhanced air search radar and long range sonar.

The "short hull" ex-"Perry" class frigates that are currently being operated by the Turkish Navy were modified with the ASIST landing platform system at the Istanbul Naval Shipyard, so that they can accommodate the S-70B Seahawk helicopters.

The possible transfer of two more "Perry" class frigates (USS|George Philip|FFG-12|1 and USS|Sides|FFG-14|1) has been approved by the U.S. Congress on 24/10/2007. These two ships are of the "long hull" type.
