The Ada class is a class of anti-submarine corvettes developed primarily for the Turkish Navy during the first stage of the MILGEM project. The Turkish Navy has commissioned all four Ada-class corvettes.

Development[]

The design objective of the Ada class was to build a modern littoral combat ship, with national anti-submarine warfare and high-seas patrol capabilities, while extensively using the principles of low observable technology in its design.[3]

According to the Ada class acquisition model, Turkey's Undersecretariat for Defense Industries (SSM) signed R&D contracts for two prototype ships considered to be testing platforms. Thus, being an open-end project, first and second ships of the class were expected to be slightly different in terms of vessel design and system configuration. The subsequent vessels, scheduled to be built by private shipyards, would have a more optimized design and configuration.[4]

All four ships of the series, TCG Heybeliada, TCG Büyükada, TCG Burgazada and TCG Kınalıada were built by the Istanbul Naval Shipyard Command. The construction works of the lead ship, TCG Heybeliada commenced on 26 July 2005. TCG Heybeliada was launched with a ceremony attended by Prime Minister of Turkey Recep Tayyip Erdoğan on 27 September 2008. On 2 November 2010, Heybeliada initiated sea acceptance trials in the Sea of Marmara.[5][6] Heybeliada entered navy service on 27 September 2011.[7] Cost of the TCG Heybeliada was reported around US$260 million.[8]

The production of the second ship of the class, TCG Büyükada, commenced on 27 September 2008. Büyükada was expected to incorporate weapon systems with notable performance, such as the ASELSAN air-search radar. Büyükada was launched on 27 September 2011 and underwent sea acceptance trials before it was officially commissioned on 27 September 2013. In September 2013, then Prime Minister Recep Tayyip Erdoğan announced that the Ada-class was to be temporarily put on hold after the completion of the first two corvettes by the Istanbul Naval Shipyard, and that the bid won by RMK Marine to build six more corvettes was canceled. Motives behind this decision was reported other shipbuilders complaining about the bidding process. He added that a new bidding process would take place.[9] Construction of TCG Burgazada commenced on 17 December 2014. The ship was launched in June 2016 and commissioned on 4 November 2018.[10] Turkish Naval Forces Command (TNFC) received its fourth and last Ada-class corvette, TCG Kinaliada (F-514) on 29 September 2019, in the commissioning ceremony held at the Istanbul Naval Shipyard.[11]

On 4 November 2019, the Defense Industries Administration (SSB) of Turkey announced that Turkey's ASW corvette TCG Kinaliada successfully test-fired Atmaca anti-ship cruise missile. Turkish Navy plans to replace the inventory of Harpoon ASM by 2022.[12]

Characteristics[]

The class vessels are propelled by a RENK CODAG Cross-Connect propulsion plant. It consists of a gas turbine rated at 23,000 kilowatts (31,000 hp) and two diesel engines rated at 4,320 kW (5,790 hp). Each diesel engine drives one controllable pitch propeller via a two-speed main reduction gear. The cross-connect gear splits the power from the gas turbine via both main reduction gears to the two shafts. The ship can be operated in Diesel mode, in single gas turbine mode, or in CODAG mode. CODAG is where diesel and gas turbine engines are providing combined power (27,320 kW).

The design concept and mission profile of the Ada-class corvette bears similarities with the Freedom-class littoral combat ship of the U.S. Navy. The Ada-class corvettes are more heavily armed, and are equipped with more capable radar and sonar systems. The Freedom class has a higher speed and variable mission modules.[13]

GENESIS (Gemi Entegre Savaş İdare Sistemi, i.e., Ship Integrated Combat Management System), a network-centric warfare management system developed by HAVELSAN and initially used in the upgraded G-class frigates of the Turkish Navy, was contracted for the first two corvettes on 23 May 2007.[14][15] In the last Ada-class corvette, Kınalıada, the ADVENT combat management system (an upgraded version of GENESIS) is installed instead of GENESIS system. It is also planned for Burgazada to be retrofited with the ADVENT combat management system.[16] The class ships have a national hull mounted sonar developed by the Scientific and Technological Research Council of Turkey.[17] The sonar dome has been developed by STM's subcontractor ONUK-BG Defence Systems, extensively employing nano-enhanced Fiber Reinforced Polymer.[18] The Ada class features an Electronic Chart Precise Integrated Navigation System (ECPINS), supplied by OSI Geospatial.[19] Integrated Platform Management System (IPMS) for controlling machinery, auxiliary systems, power generation and distribution was delivered by STM's subcontractor Yaltes JV. Main systems integrated to IPMS are power management system, fire detection system, fire fighting, damage control system, CCTV system and stability control system.[20]

Naming[]

"Ada" means island in Turkish. Each individual ship of the class is named for a Turkish island, in particular the Prince Islands in the Sea of Marmara to the southeast of Istanbul. The lead ship of the class, TCG Heybeliada, is named after Heybeliada island, where the Turkish Naval High School is located.

Export[]

The Ukrainian Ministry of Defense has ordered 2 corvettes with construction to be performed jointly by the Turkish STM and Ukrainian shipyard.[24][25] Under the deal, the first vessel will be delivered to Ukraine by the end of 2023 unfinished, to then be completed in Ukraine.[26] The deal was signed in December 2020 worth $256 million.[27][28]
