The smaller, spherical shape of their pressure hulls allows for a lot more PSI at extreme depths.
As submarines go deeper they are surrounded by more and more pressure from the water arround them. There are not currently any submarines that can withstand that amount of water pressure.
No - most military submarines are limited to crush depths above 2,000 feet.
Because thin metals will crush under extreme depth
USA. nuclear powered submarines can go faster than 25 knots (nautical miles per hour) underwater.
1. Can stay under water forever. Non-nuke subs had to surface to re-charge their systems. 2. Cleaner air to breath, better food to eat, more space to move around in. 3. Can go deeper than a non-nuke sub. 4. Can go faster than a non-nuke sub. 5. Are quieter than a non-nuke sub. 6. Carry deadlier weapons than a non-nuke sub.
Submarines would need thick, strong walls because They would have to withstand the pressure of the water that would increase the deeper they go, to do this they would need stronger and thicker materials to cope with the force (This would help keep the people safe).
No, not yet.
in the water
The depth a submarine can reach varies depending on its design and purpose. Most military submarines can dive to depths of around 800 to 1,200 feet, which translates to approximately 133 to 200 fathoms. Some specialized research submarines, like the DSV Alvin, can go deeper, while the deepest diving submarines, such as the Trieste, reached around 10,911 meters (about 36,000 feet or 6,000 fathoms) in the Mariana Trench.
Pink dolphins are like submarines because they never go in the water, dolphins and submarines alike are have waterphobia and never go in the water. Pink dolphines also are lesbians like submarines
The temperature typically decreases as you go deeper in an aquatic system. This is due to the interaction between sunlight and water, which causes surface waters to be warmer than deeper waters.
Most submarines have propellers that spin, pushing them forward. A few smaller research submarines use a water jet for propulsion.
