TCG Demirhisar was the name ship of the four her class of destroyers built for the Turkish Navy during the Second World War. The design of her class was based on the British .
Demirhisar displaced 1360LT at standard load and 1910LT at deep load. The ship had an overall length of 323feet, a beam of 33feet and a draught of 8feet. She was powered by Parsons geared steam turbines, driving two shafts, which developed a total of 34000shp and gave a maximum speed of 35.5kn. Steam for the turbines was provided by three Admiralty three-drum boilers. Demirhisar carried a maximum of 455LT of fuel oil. The ship's complement was 145 officers and ratings.[1]
The ship mounted four 45-calibre 4.7-inch (120 mm) Mark IX guns in single mounts. For anti-aircraft (AA) defence, Demirhisar had four single mounts for Oerlikon 20 mm cannon. She was fitted with two above-water quadruple mounts for 21inches torpedoes.[1]
Demirhisar was one of four I-class destroyers ordered by Turkey in 1939, two of which were purchased by the Royal Navy while construction of the other two proceeded slowly. The ship was laid down at William Denny and Brothers in Dumbarton, Scotland, in 1939. She was launched two years later, and completed in 1942. The destroyer was transferred to Turkey in later that year, where she served until her decommissioning in 1960.
