Mark 35 Torpedo
The Mark 35 torpedo was the first of the United States Navy deep-diving anti-submarine torpedoes designed for surface launch. This electrically propelled 21-inch (53-cm) torpedo was 162 inches (4.11 m) long, weighed 1770 lb (803 kg), and carried a 270 lb (122.5 kg) Torpex high explosive warhead. This torpedo used one of the earliest active guidance systems and was introduced in 1949, and was classified as obsolete in the 1960s. The Mark 35 torpedo was originally specified as the intended payload for the Grebe missile, before being replaced by the Mark 41 due to weight concerns. Mark 41 torpedo A simplified and lighter weight version of the Mark 35 was developed, specifically for air-launched use. This eliminated any equipment not needed for air-launching, saving 450 lbs. The nose also became distinctively flat-fronted. This torpedo was used as the payload in some ASW missiles, the AUM-N-2 ''Petrel'' and the SUM-N-2 ''Grebe''. See also *American 21-inc ...

Acoustic Torpedo
An acoustic torpedo is a torpedo that aims itself by listening for characteristic sounds of its target or by searching for it using sonar ( acoustic homing). Acoustic torpedoes are usually designed for medium-range use, and often fired from a submarine. The first passive acoustic torpedoes were developed nearly simultaneously by the United States Navy and the Germans during World War II. The Germans developed the G7e/T4 Falke, which was first deployed by the submarines , and in March 1943. Few of these torpedoes were actually used and quickly phased out of service in favor of the T4's successor, the G7es T5 ''Zaunkönig'' torpedo in August 1943. The T5 first saw widespread use in September 1943 against North Atlantic escort vessels and merchant ships in convoys. On the Allied side, the US Navy developed the Mark 24 mine, which was an aircraft-launched, anti-submarine passive acoustic homing torpedo. The first production Mk. 24s were delivered to the U.S. Navy in March 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High Blast Explosive
High Blast Explosive, or HBX, is an explosive used as a bursting charge in missile warheads, mines, depth bombs, depth charges, and torpedoes. History It was developed during World War II as a desensitized modification of Torpex explosives. "Ordnance Technical Data Sheet U.S. BOMB, 325-350-LB, DEPTH BOMB, MK 54/MK 54 Mod 1" Properties It is an aluminized (powdered aluminum) explosive having the same order of sensitivity as Composition B. Tests indicate that it is about 98% to 100% as powerful as Torpex, that it is definitely less sensitive than Torpex in both laboratory impact and bullet impact, that it is slightly more sensitive in these respects than TNT, and that it is about the same order as Composition B. "U.S. Explosive Ordnance, OP 1664, 1947" A difficulty with HBX is that water slowly reacts with aluminium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Engine
An electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate Laplace force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates in reverse, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. Electric motors may also be classified by considerations such as power source type, construction, application and type of motion output. They can be brushed or brushless, single-phase, two-phase, or three-phase, axial or radial flux, and may be air-cooled or liquid-cooled. Standardized electric motors provide power for industrial use.

Gyroscope
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining Orientation (geometry), orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, due to the angular momentum#Conservation of angular momentum, conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged Vibrating structure gyroscope#MEMS gyroscopes, MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring laser gyroscope, ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submer ...

Surface Combatant
Surface combatants (or surface ships or surface vessels) are a subset of naval warships which are designed for naval warfare, warfare on the surface of the water, with their own weapons and armed forces. They are generally ships built to fight other ships, submarines, aircraft or land targets, and can carry out several other missions including counter-narcotics operations and maritime interdiction. Their primary purpose is to engage space, air, surface, and submerged targets with weapons deployed from the ship itself, rather than by crewed carried craft.Naval Transformational Roadmap Office of Naval Research. Retrieved 2009-08-29. Surface ships include cruisers, destroyers, frigates, and corvettes, and several outdated types including battleships and battlecruisers. The category does not includ ...

Torpex
Torpex ("Torpedo explosive") is a secondary explosive, 50% more powerful than TNT by mass. Torpex comprises 42% RDX, 40% TNT and 18% powdered aluminium. It was used in the Second World War from late 1942, at which time some used the names Torpex and RDX interchangeably. Torpex proved to be particularly useful in underwater munitions because the aluminium component made the explosive pulse last longer, which increased the destructive power. Besides torpedoes, naval mines, and depth charges, Torpex was also used in the M.C 500lb and 1000lb bombs, the 4000lb, 8000lb, and 12000lb "cookie" H.C bombs and in the Upkeep, Tallboy and Grand Slam bombs as well as the drones employed in Operation Aphrodite. Torpex has long been superseded by H6 and Polymer-bonded explosive (PBX) compositions. It is regarded as obsolete and Torpex is unlikely to be encountered except in old munitions or unexploded ordnance, although a notable exception to this is the Sting Ray lightweight torpedo, wh ...

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 ...

SUM-N-2 Grebe
The SUM-N-2 Grebe, also known as Kingfisher E and SUM-2, was a rocket- and pulsejet-powered anti-ship and anti-submarine missile developed by the United States Navy in the late 1940s. Intended to allow a ship to deliver a torpedo at a significant distance from the launch location, it proved impractical in trials, and did not enter operational service. Design and development Grebe was developed as part of Project Kingfisher, a program administered by the National Bureau of Standards for the development of a family of torpedo-carrying missiles, allowing underwater-striking weapons to be delivered at stand-off distance from their launching platform. The program developed three air-launched weapons, initially designated Kingfisher C, D, and F; the sole surface-launched member of the family to reach the development stage was Kingfisher E, with development work beginning in 1946.Friedman 1982, p. 203. Kingfisher E, redesignated SUM-2 in September 1947 and SUM-N-2 Grebe in 1948, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AUM-N-2 Petrel
The AUM-N-2 Petrel, also known as Kingfisher C and AUM-2, was an air-to-surface missile produced as part of Project Kingfisher for the United States Navy. Intended for use against enemy surface ships and surfaced submarines, giving aircraft the ability to deliver aerial torpedoes from standoff missile, outside the range of defensive armament, it saw brief operational service in the late 1950s. The project was never considered a high priority by the Navy however, as it was useless against submerged submarines, which were considered the greatest potential threat. Following its withdrawal from operational usage, the Petrel was used as a target drone, receiving the designation AQM-41A shortly before being retired from service altogether. Design and development The development of the Petrel began in August 1944, when the U.S. Navy Bureau of Ordnance (BuOrd) began Project Kingfisher, intending to develop a series of standoff torpedo weapons. The "Kingfisher C", later designated AUM-2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
