Project history

The ships, played a huge role in battle for Atlantic and become one of the symbols of a victory in the UK. Early 1939 Admiralty formulated requirements to new patrol ship for operations in a coastal areas. Anti-submarine protection of merchant shipping should become her basic task, so new ship had to had powerful anti-submarine armament and 16-17kts speed, not yielding to surface speed of submarines. From several design one, created by Smith's Dock`s Ltd South Bank in Middlesborough, has been chosen. It was created on the basis of 160ft whaler Southern Pride, built by the same yard. As the order for the new patrol ships was from beginning supposed to be placed on the yards which do not have experience of naval shipbuilding and not familiar with Admiralty standards, the design was made according to standards of merchant shipbuilding more habitual for builders (Lloyd Register standards). Machinery with the same purpose have chosen enough conservative: well familiar to reservists triple expansion engine which without changes have borrowed at a prototype. The steam was produced by single-side fire-tube boilers of so-called "Scottish" type. Perhaps, transition to oil-firing became a unique innovation. The hull of the patrol ship, in comparison with a prototype, was lengthened by 30ft for propulsion improvement. Simultaneously it allowed to increase number of watertight compartments and additional internal volume can be used for placing of magazines and increased crew. They were re-classified from patrols to corvettes just before lead ship was laid down. The 1939 Programme provided building of 56 ships, as names of flowers were used, and all series received non-proprietary name "Flower". The beginning of war has led to order increase: under "War Emergency Programme" have built 50, and under the 1940 Programme 25 more ships. Besides, Royal Navy was replenished with three corvettes of this class ordered by France and requisitioned 1.7.1940; the fourth ship La Bastiaise was lost on a mine 22.6.1940 during sea trials, formally being still the property of the builder. Seven early-built ships received minesweeping equipment. Trials of a lead corvette in April, 1940 have opened both strong, and weaknesses of "Flower" class. The ship differed phenomenal manoeuvrability: tactical diameter on full speed was about two hull lengths at only 3° list. At the same time it became clear, that her seaworthiness was insufficient for operations in the high sea: on a wave crew very quickly were seasick, and because of a short forecastle a deck around a superstructure strongly slpashed. With last lack they have consulted, significantly having prolonged a forecastle towards a stern. Besides protection against waves, it has increased the covered volume of the hull which was used for placing increased more than in one and a half time, in comparison with the original design, crew (from 50 to 85 men). A forecastle have extended on all incomplete ships which degree of readiness supposed it (part of "War Emergency Programme" ships and the majority of the 1941 Programme). Canada also built "Flowers". At first Royal Navy has ordered 10 ships, however they were transferred to RCN before completion. Canadians built for themselves 70 more corvettes, the majority from which was extra equipped with the minesweeping equipment. The last 10 (reconsidered 1940-1941 Programme, 3rd group) differed from an original design a little: they were longer and had more stretched forecastle. All Canadian corvettes of the 1940-1941 Programme (except Dundas) had modern water-tube boilers instead of fire-tube ones. Many ships with a short forecastle latter received extended (including almost all RCN ships). 9 ships from 131 British-built corvettes were transferred to US Navy, feeling shortage of escorts in beginning of war. This delivery was realised by so-called "reverse" lend-lease.
