A submarine snorkel is a device which allows the engine of a submarine to operate submerged while still ... The engineering problem still exists in modern submarines ...
Ten Japanese submarines were equipped with Stirling engines. The first submarine in the class, Sōryū, was launched on 5 December 2007 and delivered to the navy in March 2009. The eleventh of the class is the first one that is equipped with lithium-ion batteries without a Stirling engine. [16] This submarine may have a range from AIP of 6500 ...
The GUPPY II conversion (SCB 47), implemented from 1947 to 1951, was generally similar to the GUPPY I, except for retention of both periscopes and introduction of the recently perfected snorkel. The addition of three new masts—snorkel induction, snorkel exhaust, and ESM mast—required more room in the upper portion of the sail.
Nautilus could function on her diesel engine for up to eight minutes underwater without her snorkel. The engine required a steady supply of air to operate, unlike the electric motor, and using it while submerged dropped the air pressure to the equivalent of 3,000 m (9,800 ft) above sea level, as the engine ingested air from the crew compartment ...
The submarines have been the subject of many incidents and technical problems since the design phase, including accusations of foul play and bias during the design selection, improper handling of design changes during construction, major capability deficiencies in the first submarines, and ongoing technical problems throughout the early life of ...
Submarines of this class are diesel-electric vessels and formidable long-range strike platforms that can attack ships and land targets, deploy for weeks on end, and stay relatively undetected ...
Quebec-class submarines were fitted with two regular diesel engines and a third, closed-cycle diesel engine, which used liquid oxygen to provide air-independent propulsion while the submarine was submerged. The Quebec class had a streamlined conning tower with a fixed snorkel housing at the rear end.
