The Flower class corvette (also referred to as the Gladiolus class') was a class of 267 corvettes used during World War II, specifically with the Allied navies as anti-submarine convoy escorts during the Battle of the Atlantic. Several vessels saw service with the United States Navy where they were known as Action-class patrol gunboats'.

The majority served during World War II with the Royal Navy (RN) and Royal Canadian Navy (RCN), with some being built for, or transferred to, other Allied navies such as the United States Navy (USN) (where some were manned by the U.S. Coast Guard), the Free French Naval Forces, the Royal Netherlands Navy, the Royal Norwegian Navy, the Royal Indian Navy, the Royal Hellenic Navy, the Royal New Zealand Navy and, immediately post-war, the South African Navy. Several ships built largely in Canada were transferred between the USN and RN under the lend-lease program, seeing service in both navies.

After World War II many surplus Flower-class vessels saw use in non-Allied navies the world over, as well as civilian use. is the only member of the class to be preserved as a museum ship.

Class designation

The term "corvette" was originally a French name for a small sailing warship, intermediate between the frigate and the sloop-of-war. In the 1830s the term was adopted by the RN for sailing warships of roughly similar size, primarily operating in the shipping protection role. With the arrival of steam power, paddle- and later screw-driven corvettes were built for the same purpose, growing in power, size, and armament over the decades. In 1877, the RN abolished the "corvette" as a traditional category; corvettes and frigates were then combined into a new category, "cruiser".

The months leading up to World War II saw the RN return to the concept of a small escort warship being used in the shipping protection role. The Flower-class was based on a whale-catcher design and apparently Sir Winston Churchill labelled them "corvettes", thus restoring the title for the RN. As such, there is no linear link between the Flower-class and the cruising vessels of post-1877.

There are two distinct groups of vessels in this class: the original Flower-class which was a group of 225 vessels ordered during the 1939 and 1940 building programs; and the modified Flower-class which followed with a further 69 vessels ordered from 1940 onward. The modified "Flower"s were slightly larger and somewhat better armed.

In addition, those Flower-class vessels which saw service with the USN are also known as Action-class gunboats' and carried the hull classification symbol PG (Patrol Gunboat), regardless of whether they were original or modified designs.

The generic term "Flower" is derived from the RN's use of flower names for the class.

Design

The design of the Flower-class was inspired by whale catcher Southern Pride, constructed by the Smiths Dock Company of Middlesbrough

. The class was intended to be a "stop-gap" measure for the Allied navies in their battle against Kriegsmarine U-boats. They were intended as small convoy escort ships that could be produced quickly and cheaply in large numbers. Despite naval planners intentions that they be deployed for coastal convoys, their long range meant that they became the mainstay of Mid-Ocean Escort Force convoy protection during the first half of the war.

The Flower class became an essential resource for North Atlantic convoy protection until larger vessels such as destroyers and frigates could be produced in sufficient quantities. The simple design of the Flower class using parts and techniques common to merchant shipping meant they could be constructed in small commercial shipyards all over the United Kingdom

and eastern Canada

, where larger (or more sophisticated) warships could not be built. Additionally, the use of commercial machinery meant the largely Royal Naval Reserve and Royal Naval Volunteer Reserve crews to man them would be familiar with their operation.

Flower-class vessels were relatively slow for a warship with maximum speed of . They were also very lightly armed as they were intended solely for anti-submarine warfare; many of the RCN's original Flower-class ships were initially fitted with minesweeping equipment, while virtually all of the modified Flower's were fitted with a limited anti-aircraft capability.

The original Flowers had the standard RN layout, consisting of a raised forecastle, a well deck, then the bridge or wheelhouse, and a continuous deck running aft. The modified Flowers saw the forecastle extended aft past the bridge to the aft end of the funnel, a variation known as the "long forecastle" design. Apart from providing a very useful space where the whole crew could gather out of the weather, the added weight improved the ships' stability and speed and was retrospectively applied to a number of the original Flower-class vessels during the mid and latter years of the war.

The original Flowers had a mast located immediately forward the bridge, a notable exception to naval practice at that time. The modified Flowers saw the mast returned to the normal position immediately aft of the bridge, however this does not seem to have been done in all of the modified builds or conversions of the original vessels.

A cruiser stern finished the appearance for all vessels in the class.

Orders

The RN ordered 145 Flower-class corvettes in 1939, the first 26 on 25 July with a further batch of 30 on 31 August, all under the 1939 Pre-War Programme. Following the outbreak of World War II, the British Admiralty ordered another 20 on 19 September (all from Harland & Wolff

) under the 1939 War Programme. This was followed by an order for a further ten Flower-class corvettes from other British shipbuilders two days later. Another 18 were ordered on 12 December and an additional two on 15 December, again from British shipbuilders. The RN ordered the last ten vessels (under the 1939 War Programme) from Canadian shipbuilders in January 1940.

Thus, by the end of January 1940, a total of 116 ships were building or on order to this initial design. The 10 vessels ordered from Canadian shipbuilders were transferred to the RCN upon completion. Another four vessels were ordered at Smiths Dock Company for the French Navy, the first ship being completed for the Free French Naval Forces in mid-1940 and the other three being taken over by the RN. Another 31 Flowers were ordered by the RN under the 1940 War Programme, but six of these (ordered from Harland & Wolff) were cancelled on 23 January 1941.

The RN ordered 27 modified Flower-class corvettes under the 1941 and 1942 War Programmes. British shipbuilders were contracted to build seven of these vessels under the 1941 Programme and 5 vessels under the 1942 Programme, however two vessels (one from each year's Programme) were later cancelled. Additionally, the RN ordered 15 modified Flowers from Canadian shipyards under the 1941 programme; eight of these were transferred to the USN under the Lend-Lease Programme.

The RCN ordered 70 original and 34 modified Flower-class from Canadian shipbuilders. The Canadian shipbuilders also built seven original Flowers ordered by the USN, however these vessels were transferred to the RN under the Lend-Lease Programme upon completion as wartime shipbuilding production in the United States had reached the level where the USN could dispense with vessels it had ordered in Canada. The RCN vessels had several design variations from their RN counterparts: the "bandstand," where the aft pom-pom gun was mounted, was moved to the rear of the superstructure; the galley was also moved forward, immediately abaft the engine room.

Kriegsmarine use

The French Navy had ordered six Flower-class vessels that were under construction in Saint-Nazaire

at the time of the Fall of France. They were seized by Nazi Germany and four vessels were completed for service in the Kriegsmarine. They were launched in 1943-1944 under the names PA-1 through PA-4.

Their logs have all been lost, however it is thought their war careers consisted of a mixture of coastal patrol and escort with at least one specially adapted as a sea-mobile heavy anti-aircraft platform. PA-4 (formerly ) was sunk as a blockship [72361] and the other three were put out of action or sunk by Allied air attacks.

Armament

The original Flower-class were fitted with a 4 inch (102 mm) gun on the bow, depth charge racks carrying 40 charges on the stern, a minesweeping winch, and a 2-pounder (40 mm) pom-pom gun on a "bandstand" over the engine room.

Due to initial shortages, a pair of Lewis guns was sometimes substituted for the pom-pom, which would have left the ship very vulnerable to aircraft attack in its envisaged role of coastal convoy escort and patrol in the North Sea

. The long-range endurance of the vessels, coupled with early war-time shortages of larger escort warships, saw Flowers assigned to trans-Atlantic convoy escort where Luftwaffe fighter-bombers were rarely encountered. Vessels assigned to the Mediterranean Sea

usually had their anti-aircraft capability significantly upgraded.

Detection capability was provided by a fixed ASDIC dome; this was later modified to be retractable. Subsequent inventions such as the High Frequency Radio Detection Finder (Huff-Duff) were later added, along with various radar systems (such as the Type 271), which proved particularly effective in low-visibility conditions in the North Atlantic.

The Flower-class had been designed for inshore patrol and harbour anti-submarine defence, thus many required minor modifications when the Allied navies began deploying these vessels as trans-Atlantic convoy escorts. These small warships could be supported by any small dockyard or naval station, therefore many ships came to have a variety of different weapons systems and design modifications depending upon when and where they were refitted; there is really no such thing as a 'standard Flower-class corvette'

Several of the major changes that vessels in the class underwent are indicated below, in a typical chronological order:

Original twin mast configuration changed to single mast in front of the bridge, then moved behind the bridge for improved visibility.
Heavy minesweeping gear removed for deep-sea escort work and to improve range.
Galley relocated from the stern to midships.
Extra depth-charge storage racks were fitted at the stern. Later more depth-charges stowed along walkways.
Hedgehog fitted to enable remote attacks while keeping ASDIC contact.
Surface radar fitted in a "lantern" housing on the bridge.
Forecastle lengthened to midships to provide more accommodation and better seaworthiness. Several vessels were given a "three-quarters length" extension.
Increased flare at the bow. This and the above modification created the modified Flower design for subsequent orders.
Various changes to the bridge, typically lowering and lengthening it. Enclosed compass house removed.
Extra twin Lewis guns mounted on the bridge or engine room roof.
Oerlikon 20 mm cannons fitted, usually two on the bridge wings but sometimes as many as six spread out along the engine-room roof, depending on the theatre of operations.

Note any particular ship may have had any mix of these (including none), in any order, or other specialist one-off modifications. Ships allocated to other navies such as the RCN or USN usually had different armament (3 inch {76 mm}/50 cal) and deck layouts.

A major difference between the RN vessels and the RCN, USN, and other navies' vessels was the provision of upgraded ASDIC and radar. The RN was a world leader in developing these technologies, thus RN Flowers were somewhat better equipped for remote detection of enemy submarines. A good example of this is the difficulty that RCN Flowers had in intercepting U-boats with their Canadian-designed SW1C metric radar while the RN vessels were equipped with the technologically advanced Type 271 centimetric sets. In addition, RCN vessels were incapable of operating gyrocompasses, making ASDIC attacks more difficult.

Operations

Flower-class corvettes were used extensively by both the RN and RCN during the Battle of the Atlantic. They also saw limited service elsewhere with the RN, as well as the USN and several Allied navies such as the Royal Netherlands Navy, the Royal Norwegian Navy, the Royal Hellenic Navy, the Free French Naval Forces, the Royal Indian Navy, and the Royal New Zealand Navy.

Most RN Flower-class ships drew their officers and crew from the Royal Naval Reserve and the Royal Navy Volunteer Reserve (RNVR). Many RN Flowers had captains drawn from the merchant navy.

Service on Flowers in the North Atlantic was typically cold, wet, monotonous and uncomfortable. Every dip of the fo'c'sle into an oncoming wave was followed by a cascade of water into the well deck amidships. Men at action stations were drenched with spray and water entered living spaces through hatches opened to access ammunition magazines. Interior decks were constantly wet and condensation dripped from the overheads. The head (or sanitary toilet) was drained by a straight pipe to the ocean; and a reverse flow of the icy North Atlantic would cleanse the backside of those using it during rough weather. By 1941, corvettes carried twice as many crewmen as anticipated in the original design. Men slept on lockers or tabletops or in any dark place that offered a little warmth. The warships were nicknamed "the pekingese of the ocean". They had a reputation of having poor sea-handling characteristics, most often rolling in heavy seas, with complete 80-degree rolls (40 degrees each side of the normal upright position) being fairly common; it was said they "would roll on wet grass". Many crewmen suffered severe motion sickness for a few weeks until they acclimatised to shipboard life. It should be noted however, the general design of the Flowers was extremely seaworthy (just poor sea-handling characteristics), as no Allied sailor was ever lost overboard from a Flower during World War II, outside of enemy action.

A typical action by a Flower during convoy escort duties should she encounter a surfaced U-boat was to run directly at the submarine to force it to dive (thus limiting the speed and manoeverability of the U-boat). The corvette would then keep the submarine down and pre-occupied with avoiding depth charge attacks long enough to allow the convey to safely pass. The low 16kt top speed of the Flower-class ships made effective pursuit of a surfaced U-boat (17.7kt) impossible, though it was adequate to manoeveure around submerged U-boats (8kt) or convoys, which ran at a typical maximum of 8kt, and sometimes much less in poor weather.

This technique was hampered when the Kriegsmarine began deploying its U-boats in "wolf-pack" attacks, which were intended to overwhelm the escort warships of a convoy and allow at least one of the submarines to attack the merchant vessels. Upgrades in sensors and armament for the Flowers, such as radar, HF/DF, depth-charge projectors, and ASDIC, meant these small warships were well equipped to detect and defend against such attacks, but the tactical advantage often lay with the attackers, who could operate a cat-and-mouse series of attacks intended to draw the defending Flower off-station.

Success for the Flowers, therefore, should be measured in terms of tonnage protected, rather than U-boats sunk. Typical reports of convoy actions by these craft include numerous instances of U-boat detection near a convoy, followed by brief engagements using guns or depth-charges and a rapid return to station as another U-boat took advantage of the initial skirmish to attack the unguarded convoy. Continuous actions of this kind against a numerically superior U-boat pack demanded considerable seamanship skills from all concerned, and were very wearing on the crews.

Thirty-six ships in the class were lost during World War II, many due to enemy action, some to collision with Allied warships and merchant ships. One, sunk in shallow water, was raised and repaired. Of the vessels lost to enemy action, 22 were torpedoed by U-boats, five were mined, and four were sunk by enemy aircraft. The Flower-class corvettes are credited with participating in the sinking of 47 German and four Italian submarines.

Construction of the Flower-class was superseded toward the end of the war as larger shipyards concentrated on River-class frigates, and smaller yards on the improved Castle-class corvette design.

The Flower class represented fully half of all Allied convoy escort vessels in the North Atlantic during World War II.
