What is the quietest submarine in the world?
2020 — Saab’s Ghost stealthy technology, which stands for Genuine HOlistic STealth, is Saab’s quietest technology ever—and even quieter than their upgraded Gotland-class submarine.
Why do submarines have to be quiet?
Silent running is a stealth mode of operation for naval submarines. The aim is to evade discovery by passive sonar by eliminating superfluous noise: nonessential systems are shut down, the crew is urged to rest and refrain from making any unnecessary sound, and speed is greatly reduced to minimize propeller noise.
Can a submarine break through ice?
According to a 2018 article in Popular Mechanics about American submarines in the Arctic, bursting through the ice requires careful preparation. When that fails, careful maneuvering is needed so that the submarine can break through up to 9 feet (2.5 m) of sea ice.
How dangerous are submarines?
The underwater environment is a dangerous one. Submarines face many perils of the deep. Even a small fire or gas leak inside a submerged submarine can have catastrophic consequences. A collision with another vessel or grounding may be much more serious for a submarine than for a surface ship.
What can go wrong on a submarine?
Everything else (fire, flooding, toxic gas, radiation, explosions) are minor irritants that the crew can fight. That’s why we get Submarine Pay (once called hazardous duty pay).

How deep a submarine can go?
A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.
Why can’t submarines go to the bottom of the ocean?
Deep sea submarines – the ones that go deeper than anything else – have to have very thick hulls. Their windows are made of super thick glass. They’re often quite a lot smaller than the normal type of submarines and people will only be able to travel in a small compartment.
Why can’t humans go deep in the ocean?
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.
What really sank the Kursk?
The government report confirmed that Kursk had been sunk by a torpedo explosion caused when high-test peroxide (HTP), a form of highly concentrated hydrogen peroxide, leaked from cracks in the torpedo’s casing.
