In Japan, Britain’s subsea craft has developed VICTA, which can be transformed into a submarine. With a length of 11.95 meters and a width of 2.3 meters (39.2 * 7.5 feet), the VICTA can accommodate six divers, plus a pilot and navigator. Its hull is made of matte black, which is made of carbon fiber and Diab foam core material. It has a good strength to weight ratio. < / P > < p > during the departure task, VICTA can move quickly on the sea like an ordinary ship. In this mode, it is powered by a customized seatek 725 + diesel engine that delivers 725 BHP to a konsberg KAMEWA water spray. It has a top speed of 40 knots (46 mph or 74 km / h) on water, a cruising speed of 30 knots (35 mph or 56 km / h) and a fuel range of 250 nautical miles (288 miles or 463 kilometers). < / P > < p > if you want to be invisible, Vita stops and pours water into the cabin and can dive in two minutes, and then it becomes a “wet submersible.”. That is to say, its crew are immersed in water and wearing diving equipment. Both divers and crew breathe from the ship’s open air system, so divers don’t run out of air in the tank – the system on board should be able to breathe for all eight people for four hours. < / P > < p > in submarine mode, VICTA switches its thrusters to six electric thrusters powered by lithium-ion batteries. In diving mode, it has a top speed of 8 knots (9 mph or 15 km / h), a cruising speed of 6 knots (7 mph or 11 km / h), a maximum submergence of 30 meters (98 feet) and a range of 25 nautical miles (29 miles or 46 kilometers). < / P > < p > at present, the latest prototypes are being assembled and sea trials are expected in January. At the same time, you can watch the animated version of Vita in the video below. Global Tech
