Submarines are referred to as boats rather than ships regardless of their size. [3] Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navies, large and small.

The timeline of underwater diving technology is a chronological list of notable events in the history of the development of underwater diving equipment.With the partial exception of breath-hold diving, the development of underwater diving capacity, scope, and popularity, has been closely linked to available technology, and the physiological constraints of the underwater environment.
USS Nautilus (SSN-571) was the world's first operational nuclear-powered submarine and on 3 August 1958 became the first submarine to complete a submerged transit of the North Pole.
U-995, a typical VIIC/41 U-boat on display at the Laboe Naval Memorial.

Bushnell is credited with creating the first submarine ever used in combat, while studying at Yale in 1775. [3] He called it Turtle because of its look in the water. His idea of using water as ballast for submerging and raising his submarine is still in use, as is the screw propeller, which was used in Turtle.
