Now, the company has unveiled its latest design: a personal submarine that will take two passengers to depths of up to 6,600 feet, further than any personal watercraft ever created. To reach these new depths, Triton constructed an advanced acrylic hull for its passengers to sit inside while maneuvering below the water.
How quiet are Chinese submarines?
The aim is to make the submarine as quiet as the ambient sea noise around it, typically around 90 decibels. Western submarines got close around 20-30 years ago. China has been seen as lagging. But the according to unclassified U.S. Navy estimates, the early Type-093 attack submarines are about 110 decibels.
