The G class (Turkish: Gabya sınıfı fırkateyn(ler)) is one of the frigate classes of the Turkish Navy. They are extensively modernized versions of ex-{{sclass|Oliver Hazard Perry|frigate|0}} guided-missile frigates of the US Navy, mainly designed for air defense with a weapons configuration that is optimized for general warfare.
Modernization
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 Savaş İdare Sistemi).[http://www.ssm.gov.tr/home/projects/Sayfalar/proje.aspx?projeID=48 Ship Integrated Combat Management System (GENESIS)], Undersecretariat for Defence Industries, Turkey The system was designed and implemented jointly by the Turkish Navy and HAVELSAN, a Turkish electronic hardware systems and software company.[http://www.raytheon.com/businesses/rtnwcm/groups/public/documents/content/rtn09_bus_genesis_pdf.pdf] {{dead link|date=October 2017|bot=InternetArchiveBot|fix-attempted=yes}} The first GENESIS upgraded ship was delivered in 2007, and the last delivery is scheduled for 2011.{{Cite web |url=http://www.dzkk.tsk.tr/turkce/MODERNIZASYON.php?strAnaFrame=modernizasyon&strIFrame=genesis_projesi |title=Archived copy |access-date=2010-11-16 |archive-date=2013-09-21 |archive-url=https://web.archive.org/web/20130921151924/http://www.dzkk.tsk.tr/turkce/MODERNIZASYON.php?strAnaFrame=modernizasyon&strIFrame=genesis_projesi |url-status=dead }}{{Cite news|url=https://www.afcea.org/content/turkeys-defense-industry-matures|title=Turkey's Defense Industry Matures|date=24 August 2010|newspaper=Afcea International|access-date=23 November 2021}}
The GENESIS advanced combat management system includes the following characteristics and abilities:{{Cite web |url=http://www.dzkk.tsk.tr/tdgg/genesys.php |title=Turkish Maritime Task Group |access-date=2010-11-16 |archive-date=2012-03-04 |archive-url=https://web.archive.org/web/20120304223000/http://www.dzkk.tsk.tr/tdgg/genesys.php |url-status=dead }}
- A modern and reliable system
- High performance
- Open architecture
- Capacity of tracking more than 1,000 tactical targets
- Modern digital 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, including the upgrade of the Mk-92 fire control system by Lockheed Martin{{cite web|url=http://www.bizjournals.com/albuquerque/stories/2009/02/16/daily15.html|title=Lockheed Martin to upgrade weapons systems on Turkish frigates|website=Bizjournals.com|access-date=23 November 2021}}
- The retrofitting of a new advanced SMART-S Mk2 3D air search radar to replace AN/SPS-49
- The addition of a new long range sonar{{Cite web|url=http://www.defenseindustrydaily.com/mk-41-naval-vertical-missile-launch-systems-delivered-supported-updated-02139/|title=MK 41 Naval Vertical Missile Launch Systems Delivered|website=Defenseindustrydaily.com|access-date=23 November 2021}}{{Cite web|url=https://www.reuters.com/article/usa-turkey-lockheed-idUKN0938198620080409|title=US approves $227 mln Lockheed arms sale to Turkey|date=9 April 2008|access-date=23 November 2021|website=Reuters.com}}
The Mk-41 vertical launching system (VLS) has been fitted in front of the Mk.13 launcher, similar to their installation on the {{sclass|Adelaide|frigate}}s 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.
