The Fairbanks-Morse 38 8-1/8 is a diesel engine of the two-stroke, opposed-piston type. [1] It was developed in the 1930s, and is similar in arrangement to a contemporary series of German Bombers aircraft diesels. [2]
While on the surface or at snorkel depth, the submarine may use the submarine's auxiliary or emergency diesel generator for power or ventilation [30] [31] (e.g., following a fire). [32] The diesel engine in a 688 class can be quickly started by compressed air during emergencies or to evacuate noxious (non volatile ) gases from the boat ...
Virginia-class Block III submarine USS Delaware transiting the Atlantic during her sea trials in 2019. The S9G reactor of the United States Navy is designed to generate electricity and propulsion for the Virginia-class attack submarines.
The Type 212A is a class of diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German Navy (German: U-Boot-Klasse 212 A), and the Italian Navy where it is known as the Todaro class. [7]
This design feature would be repeated on all U.S. nuclear submarines until the improved Los Angeles-class submarine, the first of which was launched in 1988. The small "turtleback" behind the sail was the exhaust piping of the auxiliary diesel generator. [citation needed] The Skipjacks also introduced the S5W reactor to U.S. nuclear submarines.

One S5W plant was also used in the United Kingdom on the Royal Navy's first nuclear-powered submarine HMS Dreadnought. [1] Some time before 1971, the S5W vessel and core replaced the S1W reactor vessel and core at the S1W prototype facility. Even though operating an S5W reactor core, the facility continued to be called S1W.
The ID series can be considered a forerunner of the current auxiliary hull numbering system, and some ships with ID numbers were later given 'A' hull symbols. Also during WWI a series of mass-produced ships were designed by the Emergency Fleet Corporation , but few were completed before the end of the war and even fewer became naval auxiliaries .
