Trawlers of the Royal Navy explained

Naval trawlers were purpose-built or requisitioned and operated by the Royal Navy (RN), mainly during World Wars I and II. Vessels built to Admiralty specifications for RN use were known as Admiralty trawlers. All trawlers operated by the RN, regardless of origin, were typically given the prefix HMT, for "His Majesty's Trawler".

Requisitioned trawlers

See main article: List of requisitioned trawlers of the Royal Navy (WWII). There were also 215 trawlers of no specific class^[13] These were commercial trawlers that the Admiralty requisitioned. The Royal Navy classified requisitioned trawlers by manufacturer, although such classes were more diverse than traditional naval classifications. Seventy-two requisitioned trawlers were lost.
