The central water channel of the facility, at a length of 602 metres (1,975 ft), could accommodate up to 7 submarines if necessary, and up to 14 submarines of different classes in all water channels. The water channels have depths up to 8 metres (26 ft), with widths ranging from 12 to 22 metres (39 to 72 ft).
Cutaway image of Sleeping Beauty (Popular Science – March 1947) Built from mild steel, the canoe was 12 feet 8 inches (3.86 m) long with a beam of 27 inches (0.69 m). A 5 hp electric motor powered by four 6-volt batteries gave the craft a maximum possible speed of 4.4 knots (8.1 km/h). At a crusing speed of 3.1 knots (5.7 km/h), it could ...
For the first time in a U.S. submarine class, 21-inch (533 mm) torpedo tubes were fitted, a tube diameter that is still standard worldwide. A more powerful non-retractable 3-inch (76 mm)/50-caliber deck gun replaced the retractable 3-inch/23-caliber gun found on previous classes.
A 16th-century Islamic painting depicting Alexander the Great being lowered in a glass submersible. The concept of underwater transport has roots deep in antiquity. There are images of men using hollow sticks to breathe underwater for hunting at the temples at Thebes, and the first known military use occurred during the siege of Syracuse (415–413 BC), where divers cleared obstructions ...

Repulse was laid down at Vickers Armstrongs' Barrow-in-Furness shipyard on 12 March 1965 and was launched on 4 November 1967, [ 1 ] She was launched by Lady Joan ...
The hull of the Albacore utilized HY-80 high-strength steel [3] with a yield strength of 80,000 psi (550 MPa), although this was not initially used to increase the diving depth relative to other US submarines. HY-80 remained the standard submarine steel through the Los Angeles class. [15] Other components were made from high-tensile steel (HTS ...
The Type II U-boat was designed by Nazi Germany as a coastal U-boat, modeled after the CV-707 submarine, which was designed by the Dutch front company NV Ingenieurskantoor voor Scheepsbouw Den Haag (I.v.S) (set up by Germany after World War I in order to maintain and develop German submarine technology and to circumvent the limitations set by the Treaty of Versailles) and built in 1933 by the ...
The Royal Navy's T class (or Triton class) of diesel-electric submarines was designed in the 1930s to replace the O, P, and R classes. Fifty-three members of the class were built just before and during the Second World War, where they played a major role in the Royal Navy's submarine operations.
