Private Super Sub submarine, reaching speeds of up to 18.5 kilometers per hour (6 photos + video)
The U-Boat Worx company presented a private submarine Super Sub at the Monaco yacht show. This is the fastest submersible in its class. Its battery capacity is enough for 96 hours of autonomous operation. It accommodates three people. The boat can also begin to automatically ascend if the pilot does not press a certain button every ten minutes. The maximum diving depth is 300 meters. And such a miracle costs 5.4 million dollars.
