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.

Submarine navigation; Absolute pressure: At sea level the atmosphere exerts a pressure of approximately 1 bar, or 103,000 N/m 2. Underwater, the pressure increases by approximately 0.1 bar for every metre of depth. The total pressure at any given depth is the sum of the pressure of the water at that depth (hydrostatic pressure)and atmospheric ...
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 ...
It has a titanium pressure hull consisting of several conjoined spheres and able to withstand tremendous pressure — during the 2012 research mission it routinely dove to 2,500 to 3,000 metres (1.6 to 1.9 mi), [18] [19] with maximum depth being said to be approximately 6,000 metres (3.7 mi).
At Titanic depths, some 12,500 feet down, the water pressure is nearly 400 times more than at the ocean's surface — some 6,000 pounds would have been pressing down on every square inch of Titan ...
The deep trenches or fissures that plunge down thousands of meters below the ocean floor (for example, the mid-oceanic trenches such as the Mariana Trench in the Pacific) are almost unexplored. [6] Previously, only the bathyscaphe Trieste , the remote control submarine KaikÅ and the Nereus have been able to descend to these depths.
The crushing pressure of the ocean at that extreme depth means that an unmanned vehicle such as a US Navy’s Curv-21 would realistically be the only vessel that could reach the missing submersible.
