HMS Mashona (F59)


HMS Mashona was a destroyer of the Royal Navy that saw service in the Second World War.

Description

The Tribals were intended to counter the large destroyers being built abroad and to lend gun support to the existing destroyer flotillas and were thus significantly larger and more heavily armed than the preceding. The ships displaced at standard load and at deep load. They had an overall length of, a beam of and a draught of. The destroyers were powered by two Parsons geared steam turbines, each driving one propeller shaft, using steam provided by three Admiralty three-drum boilers. The turbines developed a total of and gave a maximum speed of. The ships carried enough fuel oil to give them a range of at. The ships' complement consisted of 190 officers and ratings, although the flotilla leaders carried an extra 20 officers and men for the Captain and his staff.
The primary armament of the Tribal-class destroyers was eight quick-firing 4.7-inch Mark XII guns in four twin-gun mounts, designated 'A', 'B', 'X', and 'Y' from front to rear. For anti-aircraft defence, they carried a single quadruple mount for the QF two-pounder Mk II "pom-pom" AA gun and two quadruple mounts for the 0.5-inch Mark III machine gun. The ships were fitted with a single above-water quadruple mount for British 21 inch torpedo| torpedoes. The Tribals were not intended as anti-submarine ships, but they were provided with ASDIC, one depth charge rack and two throwers for self-defence, although the throwers were not mounted in all ships; Twenty depth charges were the peacetime allotment, but this increased to 30 during wartime.

Wartime modifications

Heavy losses to German air attack during the Norwegian Campaign demonstrated the ineffectiveness of the Tribals' anti-aircraft suite and the RN decided in May 1940 to replace 'X' mount with two QF Mark XVI dual-purpose guns in a twin-gun mount. To better control the guns, the existing rangefinder/director was modified to accept a Type 285 gunnery radar as they became available. The number of depth charges was increased to 46 early in the war, and still more were added later. To increase the firing arcs of the AA guns, the rear funnel was shortened and the mainmast was reduced to a short pole mast.

Construction and career

Mashona was built by Vickers Armstrong, with her machinery supplied by Parsons. She was authorised in the program year 1936. Mashona was laid down on 5 August 1936, launched on 3 September 1937 and completed by 30 March 1939.
In September 1939 she was serving with the Sixth Destroyer Flotilla at Scapa Flow. She took part in operations resulting in the sinking of on 27 May 1941. She came under heavy air attack from Ju-88 of I./77 KG of the Luftwaffe while returning to port the following day, and was bombed and sunk off the coast of Galway with the loss of 48 men. The destroyer took the survivors to Greenock.
She was awarded the following battle honours:
