Motor Minesweeper's were purpose built, wooden, shallow draft, minesweepers with both SA and LL sweeping capabilities. SA is Sweep Acoustic, a device similar to a Kanga Hammer which makes a loud thumping noise which explodes acoustic mines. LL (double L) is a pair of electric cables which are towed parallel to each other on floats and emit a strong electric pulse which generates a magnetic field which detonates magnetic mines.

Four Hundred and two Motor Minesweeper were built for the Royal Navy between 1940 and 1945.
