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.
The submarine was launched on 27 August 1983, sponsored by his second wife Eleonore, commissioned on 21 July 1984, and deactivated on 14 December 2006. In 2015, the Navy announced a Virginia-class submarine named USS Hyman G. Rickover (SSN-795) in his honor. [117] The submarine's christening took place on 31 July 2021. [118] [119] [120] [121]
K-19 was the first submarine of the Project 658 (Russian: проект-658, lit. Projekt-658) class (NATO reporting name Hotel-class submarine), the first generation of Soviet nuclear submarines equipped with nuclear ballistic missiles, specifically the R-13 SLBM.
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 ...
A German U-boat from the First World War is likely to have been sunk deliberately rather than being handed to the Allies, according to a 3D map produced by researchers.
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 ...
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.
