MTB

A Motor Torpedo Boat (MTB) was a fast, agile naval vessel used by the Royal Navy for close-range torpedo attacks on larger enemy warships. Constructed primarily of wood to reduce weight and magnetic signature, these boats relied on high speed and stealth to deliver their payloads. They played a vital role in coastal defense, convoy escort, and offensive patrols in the English Channel and Mediterranean.

The development of British MTBs accelerated in the late 1930s as tensions rose in Europe, with Vosper becoming the primary designer and builder. Entering active service at the outbreak of World War II, they were extensively deployed to counter German E-boats and protect Allied shipping. Throughout the war, MTBs engaged in numerous night actions, intelligence operations, and air-sea rescue missions. Following the war, most of the wooden-hulled vessels were quickly decommissioned, sold, or scrapped, though their legacy influenced post-war fast patrol boat designs.
