In The EARLY YEARS OF THE 20TH CENTURY,sea warfareattacking enemy vessels or defending a ship - was revolutionized by the introduction of Dreadnought -type battleship like the Brazilian vessel below.These new ships combined the latest advances in steam propulsion,
gunnery, and armour plating. The gun turret was designed to fire shells over huge distances. It was protected by armour 30cm (12 in ) thick. The measurements given for the guns of this ship refer to the bore diameter. Where we "weight" is quoted, this is the weight of the shell that the gun fires. torpedoesas as portrayed on the upper cigarette card ( right ) - were self - propelled underwater missiles, often steered by gyrocontrol. Depth charges were designed in the First World War for use against submerged U - boats. They are canisters filled with explosive that are detonated by depth-sensitive pistols. The lower cigarette card shows depth charges being fired by a "thrower" ,fired from a torpedo tube,and rolled from a tropedo tube, and rolled from the stern. Ship's shields were fitted to warships from the late 19th century onwards. The shield shown opposite depicts a traditional ship's cannon.
Submarine Facts For Kids
Check out our fun submarine facts for kids and enjoy learning about their history. Find information on what submarines are used for, how long they can remain submerged, how many crew they typically have, when they were first developed and much more. Read on for a wide range of interesting trivia and information related to submarines
Submarines are a special type of watercraft that can operate underwater.
They are typically large vessels with a high number of crew. Nuclear submarines may have a crew of over 100.
Submarines are used by the military as part of navy forces, protecting aircraft carriers, performing reconnaissance and carrying out other tasks.
Submarines are also used in other areas such as marine research, undersea exploration and salvage missions.
Some submarines can remain submerged for months at a time.
Submarines typically feature a raised tower which holds radar equipment, the periscope and other systems.
Submarines use ballast tanks to hold water, allowing them to submerge when necessary.
Early submersibles were developed in the 1600s before the first known military submarine was built in 1775. Named the ‘Turtle’, it held one person and was controlled underwater independently, the first verified submarine capable of doing so.
Both sides of the American Civil War built and used submarines.
The first submarine not propelled by human power was the French vessel named ‘Plongeur’. Launched in 1863, it used compressed air for propulsion.
Developed in the 1800s, torpedoes became an important part of submarine warfare.
French writer Jules Verne published ‘20,000 Leagues under the Sea’ in 1870, a popular science fiction novel that boosted interest in submarine design.
Submarine development and use continued through World War I and II, with German U-boats particularly effective in blocking supply lines to the UK.
Launched in 1954, the first nuclear powered submarine was the USS Nautilus. Nuclear power allowed submarines to operate at high speeds while staying underwater longer than other forms of propulsion such as diesel-electric.
Both the United States and Soviet Union maintained significant submarine fleets during the cold war.
In August 2000, a Russian submarine named ‘Kursk’ sank in the Barents Sea after a series of explosions inside the vessel, killing all 118 crew.
