Aegis Cruiser
The ''Ticonderoga'' class of guided-missile cruisers is a class of warships of the United States Navy, first ordered and authorized in the 1978 fiscal year. It was originally planned as a class of destroyers. However, the increased combat capability offered by the Aegis Combat System and the passive phased array AN/SPY-1 radar, together with the capability of operating as a flagship, were used to justify the change of the classification from DDG (guided-missile destroyer) to CG (guided-missile cruiser) shortly before the keels were laid down for and . ''Ticonderoga''-class guided-missile cruisers are multi-role warships. Their Mk 41 VLS can fire Tomahawk cruise missiles to strike land targets or anti-aircraft SM-2MR/ ERs for defense against aircraft or anti-ship missiles. Their LAMPS III helicopters, RUM-139 ASROCs, and sonar systems allow them to perform anti-submarine missions. ''Ticonderoga''-class ships are designed to be elements of carrier strike groups or amphib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guided-missile Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea denial. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—usually fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought b ...

Passive Electronically Scanned Array
A passive electronically scanned array (PESA), also known as passive phased array, is an antenna in which the beam of radio waves can be electronically steered to point in different directions (that is, a phased array antenna), in which all the antenna elements are connected to a single transmitter (such as a magnetron, a klystron or a travelling wave tube) and/or receiver. The largest use of phased arrays is in radars. Most phased array radars in the world are PESA. The civilian microwave landing system uses PESA transmit-only arrays. A PESA contrasts with an active electronically scanned array (AESA) antenna, which has a separate transmitter and/or receiver unit for each antenna element, all controlled by a computer; AESA is a more advanced, sophisticated versatile second-generation version of the original PESA phased array technology. Hybrids of the two can also be found, consisting of subarrays that individually resemble PESAs, where each subarray has its own RF front e ...

RUM-139 VL-ASROC
The RUM-139 Vertical-Launch Anti-Submarine Rocket (VL-ASROC or VLA) 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 (VLS). 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. The vertical launch missile first beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which Lift (force), lift and thrust are supplied by horizontally spinning Helicopter rotor, rotors. This allows the helicopter to VTOL, take off and land vertically, to hover (helicopter), hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale mass production, production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the Vought-Sikorsky VS-300, VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

Light Airborne Multi-Purpose System
The Light Airborne Multi-Purpose System (LAMPS) is the United States Navy's program that develops crewed helicopters to assist the surface fleet in anti-submarine warfare. The purpose of LAMPS is to scout outside the limits of a fleet's radar and sonar range to detect and track enemy submarines or missile-equipped escort ships and feed the real-time data back to their LAMPS mothership. They also have the capability to directly engage enemy targets with depth charges or torpedoes, or indirectly engage the enemy by coordinating fleet assets on site. A Mk II version was planned, but was canceled in favor of the more advanced Mk III. LAMPS III added the capabilities to use anti-ship missile systems (like the AGM-119 Penguin anti-ship missile) and night vision capability. History In October 1970, the UH-2 was selected to be the platform to function as the interim Light Airborne Multi-Purpose System (LAMPS) helicopter.Frawley 2002, p. 100. During the course of the 1960s, LAMPS had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-ship Missile
An anti-ship missile (AShM or ASM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea-skimming variety, and many use a combination of inertial guidance and active radar homing. A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. Many anti-ship missiles can be launched from a variety of weapons systems including surface warships (also referred to as ship-to-ship missiles), submarines, bombers, fighter planes, patrol planes, helicopters, shore batteries, land vehicles, and, conceivably, even infantrymen firing shoulder-launched missiles. The term surface-to-surface missile (SSM) is used when appropriate. The longer-range anti-ship missiles are often called anti-ship cruise missiles. Several countries are also developing anti-ship ballistic missiles. Etymology Both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-67 Standard
The RIM-67 Standard ER (SM-1ER/SM-2ER) is an extended range surface-to-air missile (SAM) with a secondary anti-ship capability, originally developed for the United States Navy (USN). The RIM-67 was developed as a replacement for the RIM-8 Talos, a 1950s system deployed on a variety of USN ships, and eventually replaced the RIM-2 Terrier as well, since it was of a similar size and fitted existing Terrier launchers and magazines. The RIM-66 Standard MR was essentially the same missile without the booster stage, designed to replace the RIM-24 Tartar. The RIM-66/67 series thus became the US Navy's universal SAM system, hence the designation "Standard Missile". RIM-67A SM-1 Extended Range The RIM-67A (SM-1ER Block I) was the Navy's replacement for RIM-8 Talos missile. Improved technology allowed the RIM-67 to be reduced to the size of the earlier RIM-2 Terrier missile. Existing ships with the Mk86 guided missile fire control system, or "Terrier" were adapted to employ the new m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-66 Standard
The RIM-66 Standard MR (SM-1MR/SM-2MR) is a medium-range surface-to-air missile (SAM), with a secondary role as an anti-ship missile, developed for the United States Navy (USN). A member of the Standard Missile family of weapons, the SM-1 was developed as a replacement for the RIM-2 Terrier and RIM-24 Tartar that were deployed in the 1950s on a variety of USN ships. The RIM-67 Standard (SM-1ER/SM-2ER) is an extended range version of this missile with a solid rocket booster stage. Description The Standard missile program was started in 1963 to produce a family of missiles to replace existing guided missiles used by the Terrier, Talos, and Tartar guided missile systems. The intention was to produce a new generation of guided missiles that could be retrofitted to existing guided missile systems. Standard Missile 1 The RIM-66A is the medium ranged version of the Standard missile and was initially developed as a replacement for the earlier RIM-24C as part of the Tartar Guided Missile ...

Anti-aircraft
Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface ( submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 'tiers' of air defence systems which, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tomahawk (missile Family)
The BGM-109 Tomahawk () Land Attack Missile (TLAM) is an American long-range, all-weather, jet-powered, Subsonic flight, subsonic cruise missile that is primarily used by the United States Navy and Royal Navy in ship and submarine-based land-attack operations. Developed at the Applied Physics Laboratory of Johns Hopkins University under James H. Walker near Laurel, Maryland, the Tomahawk emerged in the 1970s as a modular cruise missile first manufactured by General Dynamics. The Tomahawk aimed to fulfill the need for a medium- to long-range, low-altitude missile with diverse capabilities. Its modular design allows for compatibility with a range of warheads, including high-explosive, submunitions, and bunker-busters. The Tomahawk can use a variety of guidance systems, including Global Positioning System, GPS, Inertial navigation system, inertial navigation, and TERCOM, terrain contour matching. Over a dozen variants and upgraded versions have been developed since the original desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guided-missile Destroyer
A guided-missile destroyer (DDG) is a destroyer whose primary armament is guided missiles so they can provide anti-aircraft warfare screening for the fleet. The NATO standard designation for these vessels is DDG, while destroyers which have a primary gun armament or a small number of anti-aircraft missiles sufficient only for point-defense are designated DD. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. Guided-missile destroyers are equipped with large missile magazines, with modern examples typically having vertical-launch cells. Some contain integrated weapons systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true for navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap. Many guided-missile destroyers are also multipurpose vessels, equipped to ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
