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.
No, not yet.
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).
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.
in the water
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
Most submarines have propellers that spin, pushing them forward. A few smaller research submarines use a water jet for propulsion.
Water pressure increases as you go deeper.
submarines are important because people need to go under the sea and do what they got to do to save the world
