During World War II, Britain was equipped with a double folding canoe in special operations. This small boat has proved to be a very concealed special combat equipment on water. In particular, its successful use in Singapore made the British decide to develop an upgraded version with their own power, so there was a motorized submersible canoe nicknamed "Sleeping Beauty" (MSC for short).
"Sleeping Beauty" is a small attack ship, made of low carbon steel and aluminum, with a length of 3.86m, a width of 0.69m and a dead weight of 270kg. It can only take 1 person, and the ship cannot be folded, but its solid structure allows it to be dropped into the target waters by bombers in the air, and it can be towed or transported by other surface ships under normal circumstances.
Although the sparrow is small, it has all aspects. Sleeping Beauty has four 6V batteries to power the motor of 1.5 horsepower. The motor-driven propeller can make the ship reach the maximum speed of 4.4 knots, the cruising speed of 3./kloc-0 knots and the maximum voyage of 30~40 nautical miles. The voyage is related to the sea conditions.
There are small ballast tanks on both sides of the feet and at the bow of the special warfare players driving the ship. Through the joystick control device, players can fill the ballast tank with water to make it sink and inject air to make it float. The maximum diving depth is only15m. It is impossible for such a small ship to provide a closed cabin. Crew members need to wear diving suits and carry diving breathing equipment underwater. The storage capacity of the ship's air storage tank is limited, that is to say, the number of times of floating is limited, so the crew members need to strictly control the number of times of diving during the operation.
"Sleeping Beauty" has limited power reserves, so it may face the crisis of power shortage in practical action. It doesn't matter. Players can still paddle forward, but this is obviously a physical activity. A small mast can be hung on the ship to play a role.
As a special purpose diving canoe, it is impossible to be equipped with guns and other weapons at this size. Its combat weapon is Limpet mine, which is a hat-shaped magnetic mine with a charge of 1.6 kg. When in use, it is adsorbed at a position of about 2 meters underwater, and the target ship is destroyed by explosion. This power is enough to destroy targets such as transport ships, submarines and small warships, and may not have much effect on large military targets such as battleships. "Sleeping beauty!
Some people may wonder why such a special boat has the nickname "Sleeping Beauty", because one day an officer happened to find designer Reeves sleeping on the boat when he passed by, perhaps joking, so he was nicknamed "Sleeping Beauty". The concept of "sleeping beauty" is very advanced. It is considered to be the doyen of SDV (Navy SEAL, a special manned submersible). That year, the United States did get one for research.
"Sleeping Beauty" participated in actual combat. 1944, a special group of allied forces tried to destroy the Japanese air route in Singapore with sailboats. Unfortunately, the action was discovered by a Japanese patrol boat, and the crew had to sink the boat. Captured special warfare players were beheaded by the Japanese army. He also participated in European operations, in which special warfare players were discovered and turned back by the Germans. It is said that Britain tried to develop a larger two-seat version of "Sleeping Beauty", which may be abandoned because of the end of World War II. ?
