Welcome to the TCA Website. Our aim is to provide information about those little wooden ships that were Britain’s main line of defence against the sea mine throughout 1950’s – 90’s.

Here you will find details of the design of the ships and a brief history of each of the 118 of them, together with other facts.

You are eligible to join the TON Class Association If you served in a TON MCMV, no matter how briefly.

Associate Membership is open to others with MCM experience and interests.

You will enjoy the comradeship of fellow TONs sailors and receive information on current developments in Mine Countermeasures Technology.
