Brazilian Submarine Tonelero (S21)
''Tonelero'' (S21) was an ''Oberon''-class submarine in the Brazilian Navy. Design and construction The submarine, built by Vickers Shipbuilding and Engineering at their shipyard in Barrow, was laid down on 18 November 1971, and launched on 22 November 1972. During construction, a fire seriously damaged the submarine. The submarine was towed to Chatham Dockyard, where the central section was cut out and replaced. The fire was found to have originated in the cabling, and prompted the recabling of all under-construction ''Oberon''s. She was commissioned into the Brazilian Navy on 10 December 1977. Operational history Decommissioning and fate ''Tonelero'' was listed as active in the 1998-99 edition of ''Jane's Fighting Ships''. On 26 December 2000 the Tonelero sank at her mooring in the Rio de Janeiro navy yards due to crew error. All 9 crew members aboard escaped from the submarine.

S21 Submarino Toneleiro
S, or s, is the nineteenth letter of the Latin alphabet, used in the English alphabet, the alphabets of other western European languages and other latin alphabets worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a "sh" phoneme, so the derived Greek letter Sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''Samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ), "to hiss". The original name of the letter "Sigma" may have been ''san'', but due to the earl ...

Vickers Shipbuilding And Engineering
Vickers Shipbuilding and Engineering Limited (VSEL) was a shipbuilding company based at Barrow-in-Furness, England that built warships, civilian ships, submarines and armaments. The company was historically the Naval Construction Works of Vickers Armstrongs and has a heritage of building large naval warships and armaments. Through a complicated history the company's shipbuilding division is now BAE Systems Submarine Solutions and the armaments division is now part of BAE Systems Land & Armaments. History The company was founded in 1871 by James Ramsden (industrialist), James Ramsden as the Iron Shipbuilding Company, but its name was soon changed to Barrow Shipbuilding Company.

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although Torpedo#Classes and diameters, torpedoes of other classes and diameters have been used. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the ...

Oberon-class Submarine
The ''Oberon'' class was a ship class of 27 British-designed submarines operated by five nations. They were designed as a follow-on from the British Porpoise-class submarine, ''Porpoise'' class; physical dimensions were the same but stronger materials were used in hull construction and improved equipment was fitted. The ''Oberon''s operated during the Cold War, with duties including surveillance, tracking of other ships and submarines, delivery and retrieval of special forces personnel and serving as targets for anti-submarine training. Submarines of the class were in service until 2000. The ''Oberon'' class was arguably the best conventional submarine class of its time, with a reputation for remarkable quietness. The quietness of the ''Oberon'' vessels enabled them to operate into the late 20th century until replaced by newer classes such as the Collins-class submarine, ''Collins'' and Upholder/Victoria-class submarine, ''Victoria'' classes in Australia and Canada, respectivel ...

Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. 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 navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

Jane's Fighting Ships
''Janes Fighting Ships'' is an annual reference book of each country's warship, navy and coast guard, along with their weapons and aircraft. Included are ship names, construction data, size, speed, range, complement, engineering, armament, and sensors. This is generally followed by relevant commentary. Originally, it was illustrated with ink sketches done by founder, Fred T. Jane (1865–1916). It is his surname "Jane" that makes this title distinctive. Jane was a struggling commercial artist and journalist with an interest in naval affairs. In the 1880s he set out to record all of the armored warships serving in the world's navies. His plan was to publish this record with the title ''Ironclads of the World''. Initially ''Brassey's Naval Annual'' and various Royal Navy periodicals were the source of inspiration for his drawings. In later years he became acquainted with a collector of warship photographs, W.A. Bieber. This enabled Jane to complete nearly 500 drawings. The fir ...
