The Flower-class refers to a class of small warships built by the British Royal Navy during World War II. Designed primarily for anti-submarine warfare, these ships were known for their versatility and effectiveness in protecting convoys. The class was named after flowers, with the first ship being the HMS Flower. Constructed using a simple design, the Flower-class vessels were often equipped with depth charges and sonar equipment. They played a crucial role in the Battle of the Atlantic, helping to secure vital supply routes against German U-boats. Their relatively low cost and ease of production made them an essential asset during the war.
