The S1W reactor was the first prototype naval reactor used by the United States Navy to prove that the technology could be used for electricity generation and propulsion on submarines. The designation of "S1W" stands for S = Submarine platform; 1 = First generation core designed by the contractor; W = Westinghouse was the contracted designer
Bettis Atomic Power Laboratory, operated by Westinghouse, developed the basic reactor plant design used in Nautilus after being given the assignment on 31 December 1947 to design a nuclear power plant for a submarine. [14] Nuclear power had a crucial advantage in submarine propulsion because it is a zero-emission process that consumes no air.
British Mark XI on top, German G7e(TIII) with a US warhead in the middle and a US Mark 18 at the bottom Mark 18's electric motor. The Mark 18 was built in competition with the Bureau of Ordnance electric torpedoes, which had been in development at the Naval Torpedo Station (NTS), Newport, Rhode Island, since the 1920s, [5] in particular the Mark 20, originated in 1941 in collaboration with ...
The 38 8-1/8 was reverse-engineered in the USSR and used as a primary engine for railroad locomotives. The first Soviet mass-produced diesel locomotive, TE3, was powered by a 1470 kW (2000 hp) 2D100 engine, direct descendant of the marine 38 8-1/8 engine. The TE3 was produced in high numbers (up to 7600 units), and proved to be a reliable ...
The S5W was the standard reactor for submarines of the United States Navy from its first use in 1959 on USS Skipjack until the introduction of the Los Angeles-class submarines with S6G reactor in the mid-1970s. One S5W plant was also used in the United Kingdom on the Royal Navy's first nuclear-powered submarine HMS Dreadnought. [1]
The French-designed 1862 Alligator, first submarine of the U.S. Navy. During the American Civil War, the Union was the first to field a submarine. The French-designed Alligator was the first U.S. Navy sub and the first to feature compressed air (for air supply) and an air filtration system. It was the first submarine to carry a diver lock ...
During an underwater tour of Catalina Island, passengers aboard the SS Nautilus couldn't avoid thinking about the loss of the Titan submersible -- but that didn't stop them from boarding.
To power the new class, the Westinghouse S5W reactor plant was introduced, the third generation of submarine reactors since the launch of the USS Nautilus (SSN-571). The improved core life allowed the ship to travel at full power for 90,000 to 100,000 miles (161,000 km).
