  • HMCS Whitby was a modified Flower-class corvette that served with the Royal Canadian Navy during the Second World War. She fought primarily in the Battle of the Atlantic as a convoy escort. She was named for Whitby, Ontario.


    Flower-class corvettes like Whitby serving with the Royal Canadian Navy during the Second World War were different to earlier and more traditional sail-driven corvettes.[2][3][4] The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.[5] During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design.[6] The generic name "flower" was used to designate the class of these ships, which – in the Royal Navy – were named after flowering plants.[7]

    Corvettes commissioned by the Royal Canadian Navy during the Second World War were named after communities for the most part, to better represent the people who took part in building them. This idea was put forth by Admiral Percy W. Nelles. Sponsors were commonly associated with the community for which the ship was named. Royal Navy corvettes were designed as open sea escorts, while Canadian corvettes were developed for coastal auxiliary roles which was exemplified by their minesweeping gear. Eventually the Canadian corvettes would be modified to allow them to perform better on the open seas.[8]


    Whitby was ordered April 1942 as part of the 1942-43 modified Flower-class building programme. This programme was known as the Increased Endurance. Many changes were made, all from lessons that had been learned in previous versions of the Flower-class. The bridge was made a full deck higher and built to naval standards instead of the more civilian-like bridges of previous versions. The platform for the 4-inch main gun was raised to minimize the amount of spray over it and to provide a better field of fire. It was also connected to the wheelhouse by a wide platform that was now the base for the Hedgehog anti-submarine mortar that this version was armed with. Along with the new Hedgehog, this version got the new QF 4-inch Mk XIX main gun, which was semi-automatic, used fixed ammunition and had the ability to elevate higher giving it an anti-aircraft ability.[8]

    Other superficial changes to this version include an upright funnel and pressurized boiler rooms which eliminated the need for hooded ventilators around the base of the funnel. This changes the silhouette of the corvette and made it more difficult for submariners to tell which way the corvette was laying.[8]

    Whitby was laid down by Midland Shipyards Ltd. at Midland, Ontario 1 April 1943 and was launched 18 September 1943. She was commissioned into the Royal Canadian Navy 6 June 1944 at Midland.[9] Whitby had no major refits during her war service due to her late arrival into the conflict, however en route to Halifax for deployment, Whitby had a layover at Shelburne, Nova Scotia for repairs.[10]

    War serviceEdit

    After working up, Whitby joined the Mid-Ocean Escort Force. She was assigned to escort group C-4 as a trans-Atlantic convoy escort. She served the rest of the war with the group.[10]

    Post-war serviceEdit

    Whitby was paid off at Sorel, Quebec 16 July 1945 and laid up. She was transferred to the War Assets Corporation and sold 30 August 1946 for mercantile conversion. She emerged in 1946 as Bengo.[9][10] She was sold to the Portuguese Navy who commissioned her in April 1948. In October 1948 she was converted to a pilot tender for use in Portuguese East Africa at Maputo, in what became known as Mozambique.
