	Encyclopedia: Torpedo
		The Bangalore Torpedo, invented in 1912, is an cylindrical explosive device on the end of a pipe used to clear minefields and barbed wire.
		From the deck-mounted torpedo launcher of a vessel on the surface.
		In the case of deck or tube launched torpedoes, the diameter of the torpedo is obviously a key factor in determining the suitability of a particular torpedo to a tube or launcher, similar to the calibre of the gun.

	Quintuple Torpedo Tubes (Site not responding. Last check: 2007-10-02)
		The 21-inch torpedo was introduced in the O'BRIEN(DD-51) class of 1912, one of the immediate predecessor classes of the flush-deck four-stackers which began with the CALDWELL (DD 69)class of 1915.
		Torpedoes were fired from twin tube mounts in the O'BRIEN-class and from triple tube mounts in the CALDWELL-class.
		Torpedoes were launched individually by the ignition of a charge of fl powder from an impulse cartridge inserted into the firing mechanism.

	21-Inch Submerged Torpedo Tubes - Chapter 11
		Torpedoes are divided into three groups according to the location of the guide stud, the distances from the tail to the front of the guide stud being 109.0 inches, 141.44 inches, or 150.44 inches, depending upon the length of the torpedo.
		The torpedo is eased further into the tube, riding on the tube rollers, the block and tackle is detached, then the torpedo is eased gently info place against the stop bolt, care being taken to avoid damaging the stop bolt by forcing the Torpedo against it.
		When the torpedo is in place against the stop bolt in the tube, the propeller lock is removed, and the breech door is closed and locked, the tube being further readied for firing as explained in the preceding pages of this pamphlet.

	Submarine Torpedo Tubes and Firing Systems
		Torpedo tubes must be flooded in order to equalize the pressure inside the tube with the surrounding sea pressure so that the bowcap (muzzle door) can be opened.
		Torpedoes that were not fired had to be "drawn back" afterwards, washed down with fresh water, dried off (or blown dry using compressed air) and regreased before reloading.
		Torpedo spread was achieved by maintaining a steady course (of the submarine) and varying the gyro angle and firing interval (time between firing) for each fish.

	USS Bowfin - Torpedo Tubes
		Torpedo tubes on U.S. submarines in World War II were basically large naval guns that used compressed air rather than explosives to eject their projectiles.
		One marked difference between any torpedo tube and a gun is that the torpedo itself is self-propelling; the tube generally supplies only the initial impetus for the torpedo.
		The tubes were normally carried loaded, with ten reloads on racks forward, and four reloads aft, for a total of 24 torpedoes.

	21-Inch Submerged Torpedo Tubes - Chapter 1
		One marked difference between the torpedo tube and a gun, however, is that the torpedo tube's projectile (the torpedo) is self-propelling; the tube supplies only the initial impetus or "start" for the torpedo.
		A cardinal principle of submarine torpedo tube construction is that one or the other of the tube's two doors must always be closed, to prevent the entrance of the sea into the submarine's interior.
		With the torpedo tube flooded with sea water at the same pressure as that outside the muzzle door, the door is opened and the tube is ready to fire the torpedo.

		Torpedo boats proved devastatingly effective in the Chilean Civil War of 1891.
		The defense against torpedo boats was clear: small warships accompanying the fleet that could screen and protect it from attack by torpedo boats.
		However, her bow torpedo tube proved to be useless as the ship would usually outrun her own torpedo.

	21-Inch Submerged Torpedo Tubes - Chapter 2
		Torpedo tube barrels are constructed out of three sections, which are bronze castings, and known as the breech, middle, and muzzle sections, these three sections being joined together to form a continuous cylinder.
		In some earlier torpedo tubes, a relief valve was fitted near the muzzle end of the barrel to vent the barrel whenever its pressure exceeded the pressure of the sea by more than ten pounds per square inch, and thereby prevent injury to the hinge of the muzzle door.
		W-Openings for torpedo tube drain pipes, fore and aft, for draining the water from the tube after the torpedo has been ejected and the muzzle door is locked closed, also for flooding the tube.

	Torpedo
		Torpedoes could be launched from tubes aboard vessels of various sizes, including the new, highly touted but ineffectual torpedo boats.
		The British perfected the spar torpedo where an electronically fired explosive charge was placed on the end of a forty foot long spar that projected ten feet under water outward from the hull of the "attacking" vessel.
		The torpedo required the development of counter-measures, caused an alteration of tactics, and was useful as a weapon of terror.

	One Ton Torpedo Tubing
		Torpedo tubing tactics are similar to one ton football jigging with hula skirts mixed and matched to single- and double-tail grubs out West.
		But the significant difference between footballs and torpedoes is the torpedo tube can be cast farther, gets down faster than the football, and fishes faster using more of a barely-above-bottom baitfish approach with the torpedo as opposed to crawling or dragging it around as many tend to do to mimic foraging craws with the footballs.
		You should find the torpedo tubes snag less since they are often kept moving faster barely above bottom whereas the football jigs tend to be used more deliberately at times to smash, bang and bulldoze across bottom, getting snagged more because of more constant contact with the bottom.

	Shkval (Squall) (Russia) - VA-111 - USNI Military Database
		The solid-rocket propelled torpedo achieves a high velocity of 230 mph (386 kmh) by producing an envelope of supercavitating bubbles from its nose and skin, which coat the entire weapon surface in a thin layer of gas.
		The Shkval is fired from the standard 533-mm torpedo tube at a depth of up to 328 ft (100 m).
		The rocket-powered torpedo exits the tube at 50 knots (93 kmh) and then ignites the rocket motor, propelling the weapon to speeds four to five times faster than other conventional torpedoes.

	21-Inch Submerged Torpedo Tubes - Chapter 8
		On the top of the torpedo is a guide stud which slides in the guide slot in the top land of the interior of the barrel, keeping the torpedo in its proper position and preventing it from rotating in the tube.
		For torpedoes such as the Mark 14, or others having a distance of 141.44 inches from the tail to the front of the guide stud, the housing nearest the muzzle end of the tube will be used.
		For torpedoes such as the Mark 10, Modification 3, or others having a distance of 109.0 inches from the tail to the front of the guide stud, the housing nearest the breech end of the tube is used.

	The Fleet Type Submarine - 21-Inch Submerged Torpedo Tubes
		In any case, it is obviously impossible to cover all variations from basic torpedo tube design in a single publication, hence this pamphlet, in its text and illustrations, confines itself to the torpedo tube installations existing in SS198 and up.
		But knowledge of individual differences between the torpedo tube installations in one vessel as against another must wait upon experience with the one or the other, as well as upon access to the construction drawings applicable to a particular submarine.
		This pamphlet, as has been said, is a torpedo tube primer, and not an engineering treatise; it includes nothing "over the head" of the beginning student of submarine torpedo tubes.

	HMS Alliance Tour - Forward Torpedo Tubes and Stowage Compartment
		The tube space is separated from the stowage compartment by two watertight doors to isolate the bow section in the event of damage or flooding through the tubes.
		The 21-inch diameter torpedoes were loaded into the submarine through the circular loading hatch on portable rails and then either stowed in racks on each side of the compartment or hauled by tackles into the tubes.
		A torpedo was initially launched by compressed air, which was not itself allowed to escape from the tube and make a telltale bubble on the surface.

	21-Inch Submerged Torpedo Tubes - Chapter 5
		In its most simple form, the operation of firing a torpedo tube may be said to consist of releasing a charge of compressed air into the torpedo tube behind the torpedo.
		The spindles which set the gyro, speed, and depth mechanisms must be removed from engagement with the torpedo and retracted from the tube, and the stop bolt which holds the torpedo in position in the tube must be retracted.
		Were these spindles not entirely retracted from the tube, they would interfere with the ejection of the torpedo and cause it to jam in the tube.

		The last compartment holds four torpedo tubes, eight torpedoes and 12 bunks for the crew.
		Unlike conventional torpedoes that are blown out of the tubes by compressed air before their engines are activated, the Mark 27 is designed to slowly swim out of the tube so the sound detection equipment is not deafened and the enemy is not alerted by the noise from the rush of compressed air.
		Since it has to propel itself out of the 21-inch diameter tubes, the Mark 27 is slightly smaller (19 inches in diameter) to allow water to flow around the weapon while it travels out of the tube.

	Gas-powered tubes on Russian sub called risky [Free Republic]
		The doomed submarine Kursk was fitted with new gas-powered torpedo tubes in 1998, a launching system that is potentially riskier than the air-pressure method it replaced, according a Russian military daily.
		This impulse of water "pushes" a piston connected to a larger tank that surrounds the torpedo tube, and is connected to the torpedo tube through a slide valve.
		This impulse of water going BEHIND the torpedo in the tube is what actually pushes the torpedo out of the tube, through the (opened) torpedo hatch, and out into the water.
