HMCS Riviere du Loup 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 Rivière-du-Loup, Quebec.

Background

Flower-class corvettes like Riviere du Loup serving with the Royal Canadian Navy during the Second World War were different from earlier and more traditional sail-driven corvettes.

whaling ship design.[7] The generic name "flower" was used to designate the class of these ships, which – in the Royal Navy – were named after flowering plants.[8]

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.[9]

Construction

Riviere du Loup was ordered 2 January 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

anti-aircraft ability.[9]

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.[9]

Riviere du Loup was laid down by Morton Engineering & Dry Dock Co. at Quebec City, Quebec 5 January 1943 and was launched 2 July 1943. She was commissioned into the Royal Canadian Navy 21 November 1943 at Quebec City.[10] After arriving at Halifax she needed a month's repairs after developing issues en route. After working up she had continuing engine mechanical problems and required further repairs. During her repairs she lost most of her original crew which were reassigned and once the repairs were completed, she received almost an entirely new crew that needed to workup in Bermuda.[11]

Service history

Riviere du Loup during wartime

Riviere de Loup joined the

Mid-Ocean Escort Force (MOEF) in October 1944 as part of escort group C-3. She escorted her first convoy as a trans-Atlantic convoy escort in November but developed mechanical issues again and underwent repairs at Belfast upon arrival. She returned to active service as a MOEF escort in May 1945 and remained as such until the end of the war.[11]

Riviere de Loup was

Sorel, Quebec and placed in reserve. She was transferred to the War Assets Corporation and sold to the Dominican Navy in 1947. She was renamed Juan Bautista Maggiolo. She was broken up in 1972.[10][11]
