Flower Class Corvette

The Flower class corvette 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. HMCS Sackville (K181) is the only member of the class to be preserved as a museum ship.
