HMS Wilton (M1116) was a prototype coastal minesweeper/minehunter for the Royal Navy. She was the first warship in the world to be constructed from glass-reinforced plastic. Her design was based upon the existing Ton class minesweepers, and she was fitted with equipment recovered from the scrapped HMS Derriton. The use of GRP gave the vessel a low magnetic signature against the threat of magnetic mines.On commissioning, Wilton joined the 2nd Mine Counter Measures Squadron based at Portsmouth.
