Mark 13 Torpedo
The Mark 13 torpedo was the U.S. Navy's most common aerial torpedo of World War II. It was the first American torpedo to be originally designed for launching from aircraft only. They were also used on PT boats. Design Originating in a 1925 design study, the Mark 13 was subject to changing USN requirements through its early years with resulting on-and-off development. Early models—even when dropped low to the water at slow speeds—were prone to running on the surface, or not running at all. By late 1944, the design had been modified to allow reliable drops from as high as , at speeds up to .

Grumman TBF Avenger
The Grumman TBF Avenger (designated TBM for aircraft manufactured by General Motors) is an American World War II-era torpedo bomber developed initially for the United States Navy and Marine Corps, and eventually used by several air and naval aviation services around the world. The Avenger entered U.S. service in 1942, and first saw action during the Battle of Midway. Despite the loss of five of the six Avengers on its combat debut, it survived in service to become the most effective submarine killer and most widely-used torpedo bomber of World War II, sharing credit for sinking the super-battleships and and being credited for sinking 30 submarines. Greatly modified after the war, it remained in use until the 1960s.Wheeler 1992, p. 53. From 1942-on, production of the Avenger (in fact nearly three quarters of its the total production) was subcontracted to a purposely established division of General Motors: the Eastern Aircraft Division.

Aerial Torpedo
An aerial torpedo (also known as an airborne torpedo or air-dropped torpedo) is a torpedo launched from a torpedo bomber aircraft into the water, after which the weapon propels itself to the target. First used in World War I, air-dropped torpedoes were used extensively in World War II, and remain in limited use. Aerial torpedoes are generally smaller and lighter than submarine- and surface-launched torpedoes. History Origins The idea of dropping lightweight torpedoes from aircraft was conceived in the early 1910s by Bradley A. Fiske, an officer in the United States Navy.Hopkins, Albert Allis.

Torpedo Bomber
A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the World War I, First World War almost as soon as aircraft were built that were capable of carrying the weight of a torpedo, and remained an important aircraft type until they were rendered obsolete by anti-ship missiles. They were an important element in many famous World War II, Second World War battles, notably the United Kingdom, British Battle of Taranto, attack at Taranto, the sinking of the German battleship German battleship Bismarck, ''Bismarck'', the sinking of the British battleship ''HMS Prince of Wales (53), HMS Prince Of Wales'' and the British battlecruiser ''HMS Repulse (1916), HMS Repulse'' and the Japanese attack on Pearl Harbor. Types Torpedo bombers first appeared immediately prior to the First World War. Generally, they carried torpedo, torpedoes specifically designed for air launch, which were smaller and lighte ...

Battle Of The Coral Sea
The Battle of the Coral Sea, from 4 to 8 May 1942, was a major naval battle between the Imperial Japanese Navy (IJN) and naval and air forces of the United States and Australia. Taking place in the Pacific Theatre of World War II, the battle was the first naval action in which the opposing fleets neither sighted nor fired upon one another, attacking over the horizon from aircraft carriers instead. It was also the first military battle between aircraft carriers. To strengthen their defensive position in the South Pacific, the Japanese decided to invade and occupy Port Moresby (in New Guinea) and Tulagi (in the southeastern Solomon Islands). The plan, Operation Mo, involved several major units of Japan's Combined Fleet. Two fleet carriers and a light carrier were assigned to provide air cover for the invasion forces, under the overall command of Admiral Shigeyoshi Inoue. The U.S. learned of the Japanese plan through signals intelligence and sent two U.S. Navy carrier task f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type 91 Torpedo
The Type 91 was an aerial torpedo of the Imperial Japanese Navy. It was in service from 1931 to 1945. It was used in naval battles in World War II and was specially developed for attacks on ships in shallow harbours. The Type 91 aerial torpedo had two unique characteristics. Firstly, it used wooden stabilizers attached to the tail fins which were shed upon water entry. Secondly, it engaged an angular acceleration control system to control rolling movements, which was very advanced for its time. This system made it possible to release the Type 91 not only at a cruising speed of at an altitude of , but also in a power-glide torpedo-bombing run at the maximum speed of the Nakajima B5N 'Kate', The Type 91 torpedo was an diameter torpedo, similar in size to other nations. There were five models put into service, with high-explosive warheads weighing from with effective ranges from at . Since the Type 91 torpedo was the only practical aerial torpedo of the Imperial Japanese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morris Dam
Morris Dam (officially the Samuel B. Morris Dam) is a concrete gravity dam across the San Gabriel River in the U.S. state of California. It impounds Morris Reservoir, directly downstream of San Gabriel Dam. The dam was built in the 1930s as a water supply facility for the city of Pasadena, but is now mostly utilized for flood control and flow regulation for groundwater recharge. Situated in northern Los Angeles County, the dam impounds the Morris Reservoir in the Angeles National Forest, a few miles northeast of Azusa. From the 1940s to the 1990s, the reservoir was also used for underwater missile testing by the United States military. Design and location This dam sits south of Silver Mountain and north of Glendora Ridge, which flank the deep San Gabriel Canyon. It is roughly upstream of the San Gabriel River's mouth at the Pacific Ocean, and downstream of the river's beginning at the confluence of its East and West Forks.U.S. Geological Survey.

California Institute Of Technology
The California Institute of Technology (branded as Caltech) is a private research university in Pasadena, California, United States. The university is responsible for many modern scientific advancements and is among a small group of institutes of technology in the United States that are devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery Hale, Arthur Amos Noyes, and Robert Andrews Millikan in the early 20th century. The vocational and preparatory schools were disbanded and spun off in 1910, and the college assumed its present name in 1920. In 1934, Caltech was elected to the Association of American Universities, and the antecedents of NASA's Jet Propulsion Laboratory, which Caltech continues to manage and operate, were established between 1936 and 1943 under Theodore von Kármán. Caltech has six academic divisi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark 14 Torpedo
The Mark 14 torpedo was the United States Navy's standard submarine-launched anti-ship torpedo of World War II. This weapon was plagued with many problems which crippled its performance early in the war. It was supplemented by the Mark 18 electric torpedo in the last two years of the war. From December 1941 to November 1943 the Mark 14 and the destroyer-launched Mark 15 torpedo had numerous technical problems that took almost two years to fix. After the fixes, the Mark 14 played a major role in the devastating blow U.S. Navy submarines dealt to the Japanese naval and merchant marine forces during the Pacific War. By the end of World War II, the Mark 14 torpedo was a reliable weapon ultimately remaining in service for almost 40 years in the U.S. Navy, and even longer with other navies. Development The design of the Mark 14 started in January 1931; the Navy allocated $143,000 for its development. The Mark 14 was to serve in the new "fleet" submari ...

High Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: * chemical energy, such as nitroglycerin or Dust explosion, grain dust * pressure, pressurized gas compressor, gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * nuclear weapon, nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high ...
