Subroc
The UUM-44 SUBROC (SUBmarine ROCket) was a type of submarine-launched rocket deployed by the United States Navy as an anti-submarine weapon. It carried a 250 kiloton thermonuclear warhead configured as a nuclear depth bomb. Development SUBROC was one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. Development began in 1958, with the technical evaluation being completed in 1963. SUBROC reached Initial Operation Capability (IOC) aboard the attack submarine ''Permit'' in 1964. When SUBROC reached IOC, the US Navy's admiral in charge of weapons procurement stated that SUBROC was "…a more difficult technical problem than Polaris." Operation SUBROC could be launched from a 21-inch submarine torpedo tube. After launch, the solid fuel rocket motor fired and SUBROC rose to the surface. The launch angle then changed and SUBROC flew to its destination following a predetermined ballistic trajectory. At a predetermined time ...

Goodyear Aerospace
Goodyear Aerospace Corporation (GAC) was the aerospace and defense subsidiary of the Goodyear Tire and Rubber Company. The company was originally operated as a division within Goodyear as the Goodyear Zeppelin Corporation, part of a joint project with Luftschiffbau Zeppelin, leading to the development of rigid airships in the United States. As part of the failing relationship between the US and Germany in the era prior to World War II, the division was spun off as Goodyear Aircraft Company in 1939. The company opened a new factory in Arizona in 1941 which produced subassemblies, including subcontracted airframe construction and the design of the Goodyear F2G Corsair and Goodyear Duck. In the post-war era, the division began to diversify and made major contributions to the development of synthetic aperture radar. In 1963 they became Goodyear Aerospace, with major product lines in radar, aircraft canopies, bulletproof glass, a number of spacecraft related products, and the unique ...

Nuclear Weapon Design
Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package of a nuclear weapon to detonate. There are three existing basic design types: * pure fission weapons, the simplest and least technically demanding, were the first nuclear weapons built and have so far been the only type ever used in warfare (by the United States on Empire of Japan, Japan during World War II, WWII). * boosted fission weapons increase yield beyond that of the implosion design by using small quantities of fusion fuel to enhance the fission chain reaction. Boosting can more than double the weapon's fission energy yield. * thermonuclear weapon, staged thermonuclear weapons are essentially arrangements of two or more "stages", most usually two. The first stage is normally a boosted fission weapon as above (except for the earliest thermonuclear weapons, which used a pure fission weapon instead). Its detonation causes it to shine intensely with x-radiation, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine Missiles Of The United States
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War Anti-submarine Weapons Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

List Of Nuclear Weapons
This is a list of nuclear weapons listed according to country of origin, and then by type within the states. United States US nuclear weapons of all types – bombs, warheads, shells, and others – are numbered in the same sequence starting with the Mark 1 and () ending with the W-91 (which was canceled prior to introduction into service). All designs which were formally intended to be weapons at some point received a number designation. Pure test units which were experiments (and not intended to be weapons) are not numbered in this sequence. Early weapons were very large and could only be used as free fall bombs. These were known by "Mark" designators, like the Mark 4 which was a development of the Fat Man weapon. As weapons became more sophisticated they also became much smaller and lighter, allowing them to be used in many roles. At this time the weapons began to receive designations based on their role; bombs were given the prefix "B", while the same warhead used in other r ...

RPK-2 Viyuga
The RPK-2 Vyuga (, ''blizzard''; NATO reporting name: SS-N-15 Starfish), also designated as 81R, is a Soviet submarine-launched, nuclear-armed anti-submarine missile system, launched exclusively through torpedo tubes. The system was designed in Sverdlovsk, Russian SFSR in the 1960s. Analogous to the SUBROC missile previously used by the US Navy, it is designed to be fired from a 533 mm torpedo tube. It is boosted by a choice of mechanisms depending on model before clearing the water, firing a solid fuel rocket and delivering its payload up to away. The payload ranges from a simple depth charge to a 200 kt thermonuclear warhead. Design The RPK-2 uses a 82R torpedo or 90R nuclear depth charge in the 533 mm version, and a 83R torpedo carrying or 86R nuclear depth charge in 650 mm version. Both submarine- and surface-launched versions exist. The surface-launched versions are used by the , , and classes. The submarine-launched versions are used by the , , , , , an ...

RUM-139 VL-ASROC
The RUM-139 VL-ASROC is an anti-submarine missile in the ASROC family, currently built by Lockheed Martin for the U.S. Navy. History Design and development of the missile began in 1983 when Goodyear Aerospace was contracted by the U.S. Navy to develop a ship-launched anti-submarine missile compatible with the new Mark 41 Vertical Launching System. The development of the VLS ASROC underwent many delays, and it was not deployed on any ships until 1993. During this development, Goodyear Aerospace was bought by Loral Corporation in 1986, and this defense division was in turn purchased by Lockheed Martin in 1995. The first VLS ASROC missile was an RUR-5 ASROC with an upgraded solid-fuel booster section and a digital guidance system. It carries a lightweight Mark 46 homing torpedo that is dropped from the rocket at a precalculated point on its trajectory, and then parachuted into the sea. Beginning in 1996, the missile was replaced by the newer RUM-139A and subsequently the RUM-139 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RUR-5 ASROC
The RUR-5 ASROC (for "Anti-Submarine Rocket") is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually installed on over 200 USN surface ships, specifically cruisers, destroyers, and frigates. The ASROC has been deployed on scores of warships of many other navies, including Canada, Germany, Italy, Japan, the Republic of China, Greece, Pakistan and others. History ASROC started development as the Rocket Assisted Torpedo (RAT) program by the Naval Ordnance Test Station at China Lake in the early 1950s to develop a surface warship ASW weapon to counter the new post-World War II submarines which ran quieter, at much higher speed and could attack from much longer range with high speed homing torpedoes. In addition, the goal was to take advantage of modern sonars with a much larger detection range. An extended range torpedo delivered by parachute from th ...

UUM-125 Sea Lance
The UUM-125 Sea Lance, known early in development as the ''Common ASW Standoff Weapon'', was to be an American standoff anti-submarine missile, initially intended to carry a W89 thermonuclear warhead. It was conceived in 1980 as a successor to both the UUM-44 SUBROC and RUR-5 ASROC anti-submarine missiles. The Sea Lance was to be available in two versions, known as UUM-125A and RUM-125A. The former would be a submarine-launched version, the latter surface-launched. It was cancelled in 1990 as its importance was obviated by the collapse of the Soviet Union. Design and development In 1982, Boeing was awarded the main contract to develop the system, named the Sea Lance. By the following year, it had become apparent that developing two different versions of the missile was too ambitious, and further development of the RUM-125 was suspended. The RUM-139, a vertical-launch model of the ASROC, was developed as a stopgap weapon in this role. The Sea Lance was to be housed inside a wat ...
