Type 07 Vertical Launch Anti-submarine Rocket
is a Japanese ship-launched anti-submarine missile. Description Since FY1991, the has started developing the range-extended version of ASROC to exploit the greater direct-path range of new low-frequency sonar (OQS-XX: later OQS-2x series). After that, following the end of the Cold War, it became a complete performance improvement version including not only simple range extension but also improvement in responsiveness. The missile is fired from Mk 41 vertical launching system and the maximum speed reaches supersonic. It is controlled by inertial guidance system which uses a thrust vector control. The maximum range is said to be over 30 kilometers.

Anti-submarine Missile
An anti-submarine missile is a standoff anti-submarine weapon. Often a variant of anti-ship missile designs, an anti-submarine systems typically use a jet or rocket engine, to deliver an explosive warhead aimed directly at a submarine, a depth charge, or a homing torpedo that is carried from a launch ship, or other platform, to the vicinity of a target. History Depth charges were the earliest weapons designed for use by ships against submerged submarines. These explosives were initially dropped as the ship moved over the presumed location of a submarine. Before World War II, shipboard sonar was unable to maintain contact with a submarine at close range. Various mortar-type projectors, including Hedgehog and Squid, were devised during World War II to allow a ship to maintain sonar contact while lobbing explosive charges toward the submarine. During the Cold War, missiles were developed to provide greater range with reduced recoil. Some missiles and rockets, such as Hong San ...

Responsiveness
Responsiveness as a concept of computer science refers to the specific ability of a system or functional unit to complete assigned tasks within a given time. For example, it would refer to the ability of an artificial intelligence system to understand and carry out its tasks in a timely fashion. It is one of the criteria under the principle of robustness (from a v principle). The other three are observability, recoverability, and task conformance. Vs performance Software which lacks a decent process management can have poor responsiveness even on a fast machine. On the other hand, even slow hardware can run responsive software. It is much more important that a system actually spend the available resources in the best way possible. For instance, it makes sense to let the mouse driver run at a very high priority to provide fluid mouse interactions. For long-term operations, such as copying, downloading or transforming big files the most important factor is to provide good user- ...

SMART (missile)
SMART (Supersonic Missile Assisted Release of Torpedo) is a canister-based, long-range anti-submarine missile developed by the Defence Research and Development Organisation (DRDO) for the Indian Navy. Description SMART is a canisterised hybrid system, made up of long-range missile carrier that can travel at supersonic speed and a lightweight torpedo as payload for anti-submarine warfare (ASW) role. The objective behind the project is to develop a quick reaction system that can launch torpedo from standoff distance. The missile has a range of 643 km (400 mi) carrying a light weight torpedo of range 20 km (12.5 mi) with 50 kg high explosive warhead. SMART uses two-way data link connected to airborne or ship based submarine detection and identification systems. SMART can be launched from a surface ship or a truck-based coastal battery. The missile delivery system was developed jointly by Defence Research Development Laboratory (DRDL) and Research Centre Im ...

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]   |

Thrust Vectoring
Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket, or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle. In rocketry and ballistic missiles that fly outside the atmosphere, aerodynamic control surfaces are ineffective, so thrust vectoring is the primary means of attitude control. Exhaust vanes and gimbaled engines were used in the 1930s by Robert Goddard. For aircraft, the method was originally envisaged to provide upward vertical thrust as a means to give aircraft vertical (VTOL) or short (STOL) takeoff and landing ability. Subsequently, it was realized that using vectored thrust in combat situations enabled aircraft to perform various maneuvers not available to conventional-engined planes. To perform turns, aircraft that use no thrust vectoring must rely on aerodynamic control surfaces only, such as ailerons or elevator; aircraft ...

Supersonic Speed
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of s ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Vertical Launching System
A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of ''cells'', which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up far enough to clear the cell and the ship, then turns on to the desired course. A VLS allows surface combatants to have a greater number of weapons ready for firing at any given time compared to older launching systems such as the Mark 13 single-arm and Mark 26 twin-arm launchers, which were fed from behind by a ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
