The Evolution of Submarines: From Early Attempts to Nuclear Power
TLDR Submarines have come a long way since early attempts at underwater travel, with advancements in technology leading to the creation of watertight bodies, propulsion systems, and the ability to breathe underwater. From the first semi-submersible craft in 1775 to the development of nuclear submarines, these underwater vessels have revolutionized travel, warfare, and even civilian uses such as tourism and industrial repairs.
Timestamped Summary
00:00
Humans have long been fascinated with the idea of traveling underwater, and while early attempts were not successful, submarines were eventually invented to fulfill this desire.
02:15
The problem of underwater transportation was much bigger than originally realized, with challenges including creating a watertight body, controlling buoyancy, developing a system of propulsion, and ensuring the ability to breathe.
04:02
The first breakthrough in submersible watercraft occurred in 1775 with the creation of the turtle, a semi-submersible craft built by American inventor David Bushnell, which was used to attack British ships in New York Harbor but ultimately failed due to difficulties in drilling a hole to attach explosives.
05:55
During the American Civil War, the Confederate Navy commissioned the construction of three submarines, including the H.L. Hunley, which became the first submarine in history to sink a ship, but ultimately sank itself in the process.
07:54
John Philip Holland's invention of the Holland Four, the first submarine with a combined internal combustion electric propulsion system, led to the US Navy purchasing and commissioning it as the USS Holland, and diesel-electric submarines became the standard propulsion system for the next 50 years.
09:55
Nuclear submarines revolutionized underwater travel and warfare, breaking records for distance and speed, circumnavigating the globe, and allowing for the development of strategic submarines capable of launching nuclear missiles.
11:54
Submarines have various civilian uses, such as tourism and industrial repairs, and there has been discussion about the creation of merchant submarines for bypassing naval blockades and traveling quickly under the Arctic Ocean.
