On September 7, 1776, during the Revolutionary War, the American submersible craft Turtle attempts to attach a time bomb to the hull of British Admiral Richard Howe’s flagship Eagle in New York Harbor. It was the first use of a submarine in warfare.
The Irish inventor John Philip Holland built a model submarine in 1876 and a full scale one in 1878, followed by a number of unsuccessful ones.
When USS Los Angeles was decommissioned on 23 January 2010, Bremerton became the oldest commissioned submarine in the US fleet. USS Bremerton (SSN-698 )
|Commissioned:||28 March 1981|
|Out of service:||9 July 2018|
1578: William Bourne designs the first prototype submarine William Bourne designed one of the first recorded plans for underwater navigation, a completely enclosed boat made of wood and bound in waterproofed leather, which could be submerged and rowed beneath the surface.
Cornelis Drebbel Isaac Peral Cesare Laurenti Подводная лодка / Изобретатели British mathematician William Bourne made some of the earliest known plans for a submarine around 1578, but the world’s first working prototype was built in the 17th century by Cornelius Drebbel, a Dutch polymath and inventor in the employ of the British King James I.
No one can smoke on US submarines because it’s been prohibited since December of 2010.
USS Nautilus —world’s first nuclear submarine—is commissioned The USS Nautilus, the world’s first nuclear submarine, is commissioned by the U.S. Navy. The Nautilus was constructed under the direction of U.S. Navy Captain Hyman G. Rickover, a brilliant Russian-born engineer who joined the U.S. atomic program in 1946.
Early U-boats (1850–1914) The first submarine built in Germany, the three-man Brandtaucher, sank to the bottom of Kiel harbor on 1 February 1851 during a test dive. The inventor and engineer Wilhelm Bauer had designed this vessel in 1850, and Schweffel & Howaldt constructed it in Kiel.
A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.
The U.S. submarine fleet will be pretty much static during the 2020-30 period, dropping slightly from 68 subs of all types to 66.
Fast attack submarines The U.S. currently operates three classes of fast attack submarine: the Los Angeles, Seawolf, and Virginia classes. There are 34 Los Angeles-class submarines on active duty and 28 retired, making it the most numerous nuclear-powered submarine class in the world. Except for USS Hyman G.
With around 71 submarines in active service the US Navy has the biggest fleet in the world. Next-generation submarines are gradually being rolled out to replace the ageing Los Angeles-class fleet and their mission has been extended in response to new undersea challenges.
By making use of chemical reactions via heating Saltpeter, peroxides, or even liquid oxygen, WWII era submarines went thru a multitude of processes that stem from ancient techniques. The most notable technique that was incorporated in submarines was the air exchange system typically found on a snorkel.
Oxygen is supplied either from pressurized tanks, an oxygen generator (which can form oxygen from the electrolysis of water) or some sort of “oxygen canister” that releases oxygen by a very hot chemical reaction.
Submarine warfare took place in both the Pacific and European theaters of war. However, U.S. Navy submarines saw their greatest success against Japanese merchant vessels and warships. Submarines also played humanitarian and special operations roles in the campaign against Japan.
