The outside water pressure increases with depth and so the stresses on the hull also increase with depth. Each 10 metres (33 ft) of depth puts another atmosphere (1 bar, 14.7 psi, 101 kPa) of pressure on the hull, so at 300 metres (1,000 ft), the hull is withstanding thirty standard atmospheres (30 bar; 440 psi; 3,000 kPa) of water pressure.

When submerged, the water pressure on a submarine's hull can reach 4 MPa (580 psi) for steel submarines and up to 10 MPa (1,500 psi) for titanium submarines like K-278 Komsomolets, while interior pressure remains relatively unchanged. This difference results in hull compression, which decreases displacement.
That’s 6,000 pounds per square inch acting on the submarine – atmospheric pressure is roughly 15 pounds per square inch,” he noted in an email. Gustaf Kilander and Andrea Blanco report:
Typhoon-class submarines feature multiple pressure hulls that simplify internal design [clarification needed] while making the vessel much wider than a normal submarine. In the main body of the sub, two long pressure hulls lie parallel side by side, with a third, shorter pressure hull above and partially between them (which protrudes just below ...
The Newtsuit has fully articulated, rotary joints in the arms and legs. These provide high mobility, while remaining largely unaffected by high pressures. An atmospheric diving suit (ADS), or single atmosphere diving suit is a small one-person articulated submersible which resembles a suit of armour, with elaborate pressure joints to allow articulation while maintaining an internal pressure of ...
The pressure chamber of the OceanGate Titan was found among other debris, approximately 1,600ft from the bow of the Titanic on the sea floor by a remote operated vehicle (ROV) yesterday.
The new sphere was also steel, but smaller at 2.16 metres (7.1 ft) diameter and with thicker walls, at 127 millimetres (5.0 in), [5] calculated to withstand the 1,250 kilograms per square centimetre (123 MPa) pressure at the bottom of Challenger Deep plus a substantial factor of safety. The new sphere weighed 14.25 metric tons (31,400 pounds ...
