HMS Gannet (1916) was a Royal Navy ship classified as a sloop. Built by Hawthorn Leslie and Company, she was launched on 18 March 1916 and served primarily during World War I. The vessel was designed for anti-submarine warfare and patrol duties, reflecting the naval strategies of the time. After her commissioning, HMS Gannet operated in various roles, including escorting convoys and conducting anti-submarine patrols. She was equipped with depth charges and other armaments to counter the threat posed by enemy submarines. The ship was eventually sold for scrap in 1921, marking the end of her service.
