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- guided-missile frigates, 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'').〔(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〕 The first GENESIS upgraded ship was delivered in 2007, and the last delivery is scheduled for 2011.〔(GENESIS project ), Turkish Navy〕〔http://www.afcea.org/signal/articles/anmviewer.asp?a=2387&print=yes SIGNAL Article〕 The GENESIS advanced combat management system includes the following characteristics and abilities:〔(Ship Integrated War Administration System (Genesis) )〕 * 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〔http://www.bizjournals.com/albuquerque/stories/2009/02/16/daily15.html〕 * The retrofitting of a new advanced SMART-S Mk2 3D air search radar〔http://www.ssm.gov.tr/TR/duyurular/basinaciklamalari/Documents/ssmicrakurulubasinaciklamasi.pdf〕 to replace AN/SPS-49 * The addition of a new long range sonar〔(MK 41 Naval Vertical Missile Launch Systems Delivered )〕〔(US approves $227 mln Lockheed arms sale to Turkey )〕 The Mk-41 VLS will be fitted in front of the Mk.13 launchers, similar to their installation on the 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.〔(Turkishnavy.net: First Turkish Perry With Mk-41 VLS )〕 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「G-class frigate」の詳細全文を読む スポンサード リンク
