Torpedo Data Computer
The Torpedo Data Computer (TDC) was an early electromechanical analog computer used for torpedo fire-control on American submarines during World War II. Britain, Germany, and Japan also developed automated torpedo fire control equipment, but none were as advanced as the US Navy's TDC, as it was able to automatically track the target rather than simply offering an instantaneous firing solution. This unique capability of the TDC set the standard for submarine torpedo fire control during World War II. While the TDC's target tracking abilities were unique for submarine torpedo fire control during WWII, target tracking was used on surface ship torpedo fire control systems by a number of nations (see references in this article tUS destroyeranJapanese torpedo fire control). The TDC was the first analog computer to miniaturize the capability enough for deployment on a submarine. Replacing the previously standard hand-held slide rule-type devices (known as the "banjo" and "is/was"), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Edson Dornin
Robert Edson "Dusty" Dornin (December 30, 1912, Berkeley, California – August 31, 1982) was a United States Navy officer who served in the Pacific Theater of World War II as a very successful submarine commander. He remained in the Navy until his retirement in 1965. Pre-war Dornin entered the United States Naval Academy in 1931. He was an outstanding athlete on the basketball and lacrosse teams, but made his biggest mark in sports as a football end or wide receiver, teaming with Buzz Borries and Slade Cutter to form a powerful "troika" (numerous sources state he was an All-American, though he is not mentioned in the 1935 College Football All-America Team or any prior 1930s teams). Both his teammates would also distinguish themselves in the coming war, with Cutter also making his mark as a submariner. Cutter would later recall that Dornin "studied all the time"; he graduated 48th out of 442 in the Class of 1935. After serving on the battleship (1935–37) and the destroye ...

Bureau Of Ordnance
The Bureau of Ordnance (BuOrd) was a United States Navy organization, which was responsible for the procurement, storage, and deployment of all naval weapons, between the years 1862 and 1959. History The Bureau of Ordnance was established as part of the Department of the Navy by an act of Congress, on July 5, 1862 (12 Stat. 510). The act split the Navy's existing Bureau of Ordnance and Hydrography (1842–1862) into two entities by transferring hydrographic functions into the newly established Bureau of Navigation. During the early 20th century, BuOrd became involved in the development of aerial weapons. This often led to friction with the Bureau of Aeronautics (BuAer), which had responsibility for the development of Naval aircraft. BuAer's work on "pilotless aircraft," or drones, conflicted with BuOrd's development of guided missiles. After World War II, the Navy examined ways to improve coordination between the two bureaus; ultimately, the decision was made to merge the t ...

Acoustic Homing
Acoustic homing is the process in which a system uses the sound or acoustic signals of a target or destination to guide a moving object. There are two types of acoustic homing: passive acoustic homing and active acoustic homing. Objects using passive acoustic homing rely on detecting acoustic emissions produced by the target. Conversely, objects using active acoustic homing make use of sonar to emit a signal and detect its reflection off the target. The signal detected is then processed by the system to determine the proper response for the object. Acoustic homing is useful for applications where other forms of navigation and tracking can be ineffective. It is commonly used in environments where radio or GPS signals can not be detected, such as underwater. History The idea of using sound for navigation and homing dates back centuries and has been developed over time, so the concept of acoustic homing can not be attributed to a single individual. Certain animals have always use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaiten
were crewed torpedoes and suicide attack, suicide craft, used by the Imperial Japanese Navy in the final stages of World War II. Background In recognition of the unfavorable progress of the war, towards the end of 1943 the Japanese high command considered suggestions for various suicide craft. These suggestions were initially rejected, but later deemed necessary. Various suicide craft were developed in the Japanese Special Attack Units. For the Navy, this meant ''Kamikaze'' planes, ''Ohka'' piloted bombs, ''Shinyo (suicide boat), Shinyo'' suicide boats, ''Kaiten'' submarines, and ''Fukuryu'' suicide divers or human mines. The ''Kamikazes'' were somewhat successful, and the second most successful were the ''Kaitens''. Research on the first Kaiten began in February 1944, followed on 25 July of the same year by the first prototype. By 1 August, an order for 100 units had been placed. Development The very first Kaiten was nothing much more than a Type 93 torpedo engine compar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homing Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially, a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though somet ...

Robert Whitehead (engineer)
Robert Whitehead (3 January 1823 – 14 November 1905) was an English engineer who was most famous for developing the first effective self-propelled naval torpedo. Early life He was born in Bolton, England, the son of James Whitehead, a cotton-bleacher, and his wife Ellen Whitehead née Swift. He trained as an engineer and draughtsman, and attended the Mechanics' Institute, Manchester. His first professional employment was at a shipyard in Toulon, France, for Philip Taylor & Sons, and then as a consultant engineer in Milan, Italy. He then moved to Trieste, on the Adriatic Sea, Adriatic coast of Austrian Empire, Austria. Whitehead's work in Trieste was noticed by the owners of ''Fonderia Metalli'', a metal foundry in the nearby city of Fiume (today Rijeka, Croatia). In 1856, Whitehead became manager of the company, and changed its name to ''Stabilimento Tecnico di Fiume'' (STF). STF produced marine steam boilers and engines, which were the most modern products of that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
