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

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 first nuclear-powered vessel, the submarine USS Nautilus, put to sea in 1955. USS Nautilus marked the beginning of the transition of submarines from relatively slow and short-ranged conventional submarines to ones capable of sustaining 20–25 knots (37–46 km/h; 23–29 mph) submerged for weeks on end.
The first prototype, a 3-meter (10-feet) long submarine called EMS-1, was designed and tested in 1966 by Stewart Way, a professor of mechanical engineering at the University of California, Santa Barbara. Way, on leave from his job at Westinghouse Electric, assigned his senior year undergraduate students to build the operational unit. This MHD ...
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.
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.
For a long time, the Mark 37 was a primary U.S. submarine-launched ASW torpedo. It was replaced by the Mark 48 starting in 1972. The remaining inventory was then rebuilt and sold to several countries, including Israel, as the NT-37C after the vacuum tube guidance systems were replaced by solid-state electronics and the electric propulsion was ...
