The F223 Karlsruhe was the fourth vessel in the Köln-class (Type 120) frigate series of the German Navy, distinguished by its elegant lines and smooth-deck design. Constructed primarily from shipbuilding steel, with some superstructure parts made of aluminum, the ship featured a diagonally cut bow and knuckle ribs in the foredeck, which facilitated maneuverability. Its hull was divided into 13 watertight compartments, enhancing its survivability at sea. The ship’s propulsion system included gas turbines, necessitating large side air inlets that could be closed by lamellas. The Karlsruhe's stern was designed with a round shape, and it sported a large, sloped funnel with a skirt. Its superstructure was topped with a tall lattice mast equipped with radar and other antennas, crucial for navigation and combat operations. Armament on the Karlsruhe was comprehensive for its class, including a 10 cm gun on the forecastle, a higher-positioned twin 4 cm gun, and two quadruple anti-submarine missile launchers (37.5 cm) from Bofors. Additional armament included a second 10 cm gun on the quarterdeck, multiple 4 cm guns (single and double mounts), and two 53.3 cm torpedo tubes for firing Mk-44 torpedoes. The ship also featured mine rails running from behind the torpedo tubes to the stern, indicating its multi-role capabilities. Laid down on 29 October 1958 and launched on 15 August 1959 at Stülcken & Sohn in Germany, Karlsruhe was commissioned into the German Navy on 7 April 1962. After active service, the vessel was sold to the Turkish Navy, where it was renamed Gazi Osman Pasa (D-360) on 28 March 1983, and later Gelibolu in 1984. The ship remained in service until its final decommissioning on 27 June 1994, marking its significant role in post-war naval development and international service.
