Ships -- Flower-class ( modified )
Main article : American Flower class corvettes
The Flower-class corvette (also referred to as the Gladiolus class after the lead ship) was a British class of 294 corvettes used during World War II, specifically with the Allied navies as anti-submarine convoy escorts during the Battle of the Atlantic. Royal Navy ships of this class were named after flowers, hence the name of the class. The majority served during World War II with the Royal Navy (RN) and Royal Canadian Navy (RCN). Several ships built largely in Canada were transferred from the RN to the United States Navy (USN) under the lend-lease programme, seeing service in both navies. Some corvettes transferred to the USN were manned by the US Coast Guard. The vessels serving with the US Navy were known as Temptress and Action-class patrol gunboats. Other Flower-class corvettes served with 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, the Royal Yugoslav Navy, and, immediately post-war, the South African Navy. After World War II many surplus Flower-class vessels saw worldwide use in other navies, as well as civilian use. HMCS Sackville is the only member of the class to be preserved as a museum ship.
