According to the Commander of the Ukrainian Navy, the corvette Hetman Ivan Mazepa has successfully completed another round of technical inspections.
The Ukrainian newbuild is based on the Turkish ADA class, a nationally developed submarine attack and patrol corvette (100 metres, 2,000 tonnes) with predominantly national technical components. The Mazepa, the first of two ships on order - with the option to expand to four units - was built at the RMK shipyard in Istanbul from September 2021. Ukrainian President Volodymyr Zelensky christened the ship in mid-August 2022 and it was launched by his wife at the beginning of October 2022. Since March 2024, the crew has been trained on board by the Turkish Navy and the shipyard.
The armament includes a Leonardo 76 mm super-rapid cannon and the 35 mm Gökdeniz CIWS for close-range defence. In addition, eight missile launchers are planned, although the final selection is still pending. The Harpoon (USA), Atmaca (Turkey), Naval Strike Missile (Norway) or the Ukrainian R-360 Neptun ASM are being considered.
Air defence is provided by a vertical launcher for VL MICA missiles from MBDA. In addition, the Thales Smart-S Mk2 3D multifunction radar, the Turkish ARES-2 ESM system and the Thales STIR 1.2 EO Mk2 fire control system are integrated.
Anything is possible - as long as it is built within the Black Sea.
Addendum dated 28 February 2025:
An attentive reader asked what the significance was of the fact that this new ship now bears the hull number "F 211" of the old German frigate Köln (Bremen class, type F122). The answer was as follows:
Identifiers or Fuselage numbers of warships - also known as "Hull Number" - are not subject to any standardised rule.
The NATO system, consisting of a single letter (according to the type and task of the ship) and a number, usually consisting of several digits (often in ascending order within a national ship class), is organised in a similar way to the US system. Since 1907, a combination of letters (type indicator) followed by a serial number in consecutive order, such as DDG 106 for the "USS Stockdale" as the 106th ship of the DDGs (although only the 55th of the Arleigh Burke class and its various construction lots). However, only the number is usually displayed on the bow and/or stern.
Other navies have different systems that often consist only of numbers. Another way would be the designation according to squadrons and their units, e.g. "14" as the 4th ship of the first formation. Occasionally, therefore, designations are changed, also for reasons of tactics or deception.
Although the NATO system is also used in many Western-orientated navies, Ukraine is not yet allowed to feel bound by it - so it is free to choose its own designation system. Until now, however, Ukraine had labelled its ships with the letter "U" and a three-digit number - the 200 series mostly for submarines and small missile boats. Units up to "U 209 Ternopil", a replica of the Soviet-era Grisha-class submarine hunter built in Kiev from 2000 onwards, were known. Why the "Hetman Mazepa" now has an "F" on its hull - perhaps in line with Western systems.
In the civil sector, individual ship identifiers are assigned for identification and administrative uniqueness (e.g. IMO followed by a 7-digit number), which are fixed similar to a chassis number and are not assigned a second time (International Maritime Organisation).

"Anything is possible - as long as it is built within the Black Sea."
However, the ship is not being built in the Black Sea, but in Istanbul. According to Article 19 of the Montreux Treaty, warships of belligerent powers are prohibited from passing through the strait unless they are returning to their home port.
Therefore, Hetman Ivan Mazepa is not allowed to enter the Black Sea until the war is over.
And where should it be used? Sooner or later, the UA will be landlocked!
