The G class (Turkish: Gabya s?n?f? f?rkateyn(ler)) is one of the frigate classes of the Turkish Navy. They are extensively modernized versions of ex- Oliver Hazard Perry-class guided-missile frigates of the US Navy, mainly designed for air defense with a weapons configuration that is optimized for general warfare.
The G-class frigates have undergone a major modernization program which included the retrofitting of a Turkish digital combat management system named GENESIS (Gemi Entegre Sava? ?dare Sistemi). The system was designed and implemented jointly by the Turkish Navy and HAVELSAN, a Turkish electronic hardware systems and software company. The first GENESIS upgraded ship was delivered in 2007, and the last delivery is scheduled for 2011.
The GENESIS advanced combat management system includes the following characteristics and abilities:
The modernization program also includes:
The Mk-41 VLS will be fitted in front of the Mk.13 launchers, similar to their installation on the Adelaide-class frigates of the Royal Australian Navy, which are Australian-built derivatives of the Oliver Hazard Perry-class frigates. TCG Gediz became the first ship in the class to receive the Mk 41 VLS installation.
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 helicopter.
In addition the ex-USS Duncan was sold to the Turkish Navy as a parts hulk
