The Flower-class corvette was a British class of 294 corvettes used during World War II by the Allied navies particularly as anti-submarine convoy escorts in the Battle of the Atlantic. Royal Navy ships of this class were named after flowers.
The Hunt class was a class of escort destroyer of the Royal Navy. The first vessels were ordered early in 1939, and the class saw extensive service in the Second World War, particularly on the British east coast and Mediterranean convoys. They were named after British fox hunts. The modern Hunt-class GRP hulled mine countermeasure vessels maintain the Hunt names lineage in the Royal Navy.

The Loch class was a class of anti-submarine (A/S) frigate built for the Royal Navy and her Allies during World War II. They were an innovative design based on the experience of three years of fighting in the Battle of the Atlantic and attendant technological advances. Some shipyards had trouble building these larger ships, which led to widespread use of the Castle-class corvette, introduced around the same time.
The Bay class was a class of 26 anti-aircraft (A/A) frigates built for the Royal Navy under the 1943 War Emergency Programme during World War II. They were based on the hulls of incomplete Loch class anti-submarine (A/S) frigates.
