X Craft Plan
Midget Submarine Book
Known individually as X-Craft, the vessels were designed to be towed to their intended area of operations by a full-size 'mother' submarine - (usually one of the T class or S class) - with a passage crew on board, the operational crew being transferred from the towing submarine to the X-Craft by dinghy when the operational area was reached, the passage crew returning with the dinghy to the towing submarine. Once the attack was over, the X-Craft would rendezvous with the towing submarine and then be towed home. Range was limited primarily by the endurance and determination of their crews, but was thought to be up to 14 days in the craft or 1,500 miles (2,400 km) distance after suitable training. Actual range of the X-Craft itself was 500 nmi (926 km) surfaced and 82 nmi (152 km) at 2 knots submerged.
The X class submarines' weapons were two side-cargoes - explosive charges each held on opposite sides of the hull with two tons of explosive (amatol) each. The intention was to drop these on the sea bed underneath the target then creep away. The charges were set off by a time fuse.
