HMS Whitby was a Whitby-class or Type 12 anti-submarine frigate of the Royal Navy of the United Kingdom built by Cammell Laird and Co Ltd, Birkenhead. She was launched on 2 July 1954 and commissioned on 10 July 1956.
Design
The Whitby-class was designed as a class of specialist anti-submarine warships, intended to counter fast modern diesel-electric submarines. As such, the design was required to reach a speed of at least 27 knots (31 mph; 50 km/h), maintaining high speed in rough weather conditions and have a range of 4,500 nautical miles (5,200 mi; 8,300 km) at 12 knots (14 mph; 22 km/h). To meet these requirements, the Type 12s had a new hull form and, unlike the contemporary Type 41 anti-aircraft and Type 61 air direction frigates, were powered by steam turbines.[1][2]
Whitby was 370 feet 0 inches (112.78 m) long overall and 360 feet 0 inches (109.73 m) at the waterline, with a beam of 41 feet 0 inches (12.50 m) and a draught of 11 feet 0 inches (3.35 m) forward and 13 feet 0 inches (3.96 m) at the propellers.[3] The ships were powered by the new Y-100 machinery in which the ship's boilers and steam turbines were designed as a closely integrated set of machinery to increase efficiency. Two Babcock & Wilcox water-tube boilers fed steam at 550 pounds per square inch (3,800 kPa) and 850 °F (454 °C) to two sets of geared steam turbines which drove two propeller shafts, fitted with large (2 feet (0.61 m) diameter) slow-turning propellers. The machinery was rated at 30,000 shaft horsepower (22,000 kW), giving a speed of 29 knots (33 mph; 54 km/h).[4][5] Crew was about 189 when operated as a leader and 152 as an ordinary ship.[6]
A twin 4.5-inch (113 mm) Mark 6 gun mount was fitted forward, with 350 rounds of ammunition carried, with close-in armament of a stabilised STAAG (Stabilised Tachymetric Anti-Aircraft Gun) twin Bofors 40 mm L/60 gun mount aft.[7] The design anti-submarine armament consisted of twelve 21-inch torpedo-tubes (eight fixed and two twin rotating mounts) for Mark 20E Bidder homing anti-submarine torpedoes, backed up by two Limbo anti-submarine mortars fitted aft. The Bidder homing torpedoes proved unsuccessful however, being too slow to catch modern submarines, and the torpedo tubes were soon removed.[8]
The ship was fitted with a Type 293Q surface/air search radar on the foremast, with a Type 277 height-finding radar on a short mast forward of the foremast. A Mark 6M fire control system (including a Type 275 radar) for the 4.5 inch guns was mounted above the ship's bridge, while a Type 974 navigation radar was also fitted.[9][8] The ship's sonar fit consisted of Type 164 search, Type 170 fire control sonar for Limbo and a Type 162 sonar for classifying targets on the sea floor.[10][8]
Service
Whitby was laid down at Cammell Laird's Birkenhead shipyard on 30 September 1952, was launched on 2 July 1954 and completed on 10 July 1956.[11]
On completion, she was assigned to the 3rd Training Squadron based at Londonderry Port.[12] In 1960 Desmond Cassidi was appointed as her captain. During 1966 she saw service in the Mediterranean and Atlantic. In 1968 she undertook fishery protection duties off the coast of Greenland - the first ship to have visited those waters since 1966. In 1968 she took part in 'Navy Days' at Portsmouth Dockyard.[13]
