G-class frigate

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-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.

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).[5] The system was designed and implemented jointly by the Turkish Navy and HAVELSAN, a Turkish electronic hardware systems and software company.[6] The first GENESIS upgraded ship was delivered in 2007, and the last delivery is scheduled for 2011.[7][8]

The GENESIS advanced combat management system includes the following characteristics and abilities:[9]

  • 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 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.[14]

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.

gollark: Indeed.
gollark: It's a complex protocol. You would need specialised hardware of some sort I think.
gollark: Firecubez, I mean.
gollark: PCIe allows direct memory access. However, *you* probably can't really do much with that.
gollark: You simulate every particle in the FPGA using the universe's physical laws for every test case. Or just run test cases normally.
