I Class Destroyer were British destroyers from the interwar period and World War II. The construction of all units of this type began in the second half of the 1930s. The total length of a single ship of this class at the time of launching was 98.5 meters, with a width of 10.1 meters and a draft of 3.8 meters. Full displacement reached approx. 1920 tons, and the maximum speed was approx. 36 knots. The armament at the time of launching consisted of: four single 120 mm guns, ten 533 mm torpedo tubes, depth charge drop-offs and sea mines. British Type I destroyers were generally modeled on the previous H-class destroyers, but their torpedo armament was significantly strengthened and the shape of the main superstructure was changed. With the increased displacement of Type I vessels, they had some minor stability problems. It is worth adding that they had good anti-submarine anti-submarine (ZOP) weapons by the standards of the late 1930s and could be relatively easily converted into mines. During World War II, destroyers of this class were reinforced with anti-aircraft weapons and new electronic equipment, especially radars, was installed. It is worth adding that in 1938 four ships of this class were ordered by Turkey, but in 1942 it received only two such ships, which remained in the line until 1960.
