German Frigate Augsburg (F213)
''Augsburg'' was a of the German Navy. The vessel was laid down in April 1987 by Bremer Vulkan, in Bremen, Germany and launched on 17 September 1987. The vessel was commissioned on 3 October 1989. The ship has been deployed as part of Operation Enduring Freedom – Horn of Africa and Operation Atalanta in the Middle East and Indian Ocean and has seen service in the Mediterranean Sea. The vessel is currently based at Wilhelmshaven, Germany. Construction and commissioning ''Augsburg'' was laid in April 1987 at the yards of Bremer Vulkan, Bremen and launched on 17 September 1987. After undergoing trials ''Augsburg'' was commissioned on 3 October 1989. She is currently based at Wilhelmshaven as part of ''4. Fregattengeschwader'', forming a component of ''Einsatzflottille 2''. She has the nickname "Wilde 13", a reference to her pennant number, and the German children's story ''Jim Button and the Wild 13'', which was turned into a production by the marionette theatre Augsburger Pupp ...

Bremer Vulkan
Bremer Vulkan AG was a prominent German shipbuilding company located at the Weser river in Bremen-Vegesack. It was founded in 1893 and closed in 1997 because of financial problems and mismanagement. All together Bremer Vulkan built about 1100 ships—including the ships of the predecessor Johann Lange Shipyard—of different types. It is remarkable that the Bremer Vulkan, with the exception of both World Wars, only built civilian ships; production of naval ships except during wartime first started in the 1980s. History Bremer Vulkan AG was founded 1893 in Vegesack-a suburb of the city of Bremen–by a group of investors and Bremen merchants and by overtaking the 1805 founded Johann Lange Shipyard. Two years later the Bremer Vulkan bought the ''Bremer Schiffbaugesellschaft'' – former ''H. F. Ulrichs Shipyard'' which launched the first ship in 1839 - including all its modern shipbuilding facilities. The first director of the Bremer Vulkan became the engineer Victor Nawatzki ( ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Otobreda 76 Mm
The OTO Melara 76 mm gun is a naval gun built and designed by the Italian defence company OTO Melara. It is based on the OTO Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales. The system is compact enough to be installed on relatively small warships. Its high rate of fire and the availability of several types of ammunition make it capable of short-range anti-missile point defence, anti-aircraft, anti-surface, and ground support. Ammunition includes armour-piercing, incendiary, directed fragmentation effects, and a guided round marketed as capable of destroying manoeuvring anti-ship missiles. It can be installed in a stealth cupola. The OTO Melara 76 mm has been widely exported, and is in use by sixty navies. It was favoured over the French 100mm naval gun for the joint French/Italian project and FREMM frigate. On 27 September 2006 Iran announced it had started mass production of a naval gun named the Fajr-27, which is a reverse-engineered OTO Me ...

SLQ-25 Nixie
The AN/SLQ-25 Nixie and its variants are towed torpedo decoys used on US and allied warships. It consists of a towed decoy device (TB-14A) and a shipboard signal generator. The decoy emits signals to draw a torpedo away from its intended target. The Nixie attempts to defeat a torpedo's passive sonar by emitting simulated ship noise, such as propeller and engine noise, which is more attractive than the ship to the torpedo's sensors. The AN/SLQ-25A Nixie is a clean-sheet design when compared to the AN/SLQ-25 Nixie. Apart from a few minor mechanical components, they share no common parts. The AN/SLQ-25A utilises a fiber optic tow cable (FOTC) and a 10-horsepower RL-272C double drum winch. Several engineering changes resulted in COTS equipment being utilised extensively in the system. A diagnostic program can be initiated locally or from the remote control station, and tests all electronic functions. The AN/SLQ-25B includes equipment of the AN/SLQ-25A and incorporates a towed ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decoy
A decoy (derived from the Dutch ''de'' ''kooi'', literally "the cage" or possibly ''ende kooi'', " duck cage") is usually a person, device, or event which resembles what an individual or a group might be looking for, but it is only meant to lure them. Decoys have been used for centuries most notably in game hunting, but also in wartime and in the committing or resolving of crimes. Hunting In hunting wildfowl, the term decoy may refer to two distinct devices. One, the duck decoy (structure), is a long cone-shaped wickerwork tunnel installed on a small pond to catch wild ducks. After the ducks settled on the pond, a small, trained dog would herd the birds into the tunnel. The catch was formerly sent to market for food, but now these are used only by ornithologists to catch ducks to be ringed and released. The word ''decoy'', also originally found in English as "coy", derives from the Dutch ''de Kooi'' (the cage) and dates back to the early 17th century, when this type of duck ...

Electronic Counter-measures
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers. History The first example of electronic countermeasures being applied in a combat situation took place during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Warfare Support Measures
In military telecommunications, electronic support (ES) or electronic support measures (ESM) gather intelligence through passive "listening" to electromagnetic radiations of military interest. They are an aspect of electronic warfare involving actions taken under direct control of an operational commander to detect, intercept, identify, locate, record, and/or analyze sources of radiated electromagnetic energy for the purposes of immediate threat recognition (such as warning that fire control RADAR has locked on a combat vehicle, ship, or aircraft) or longer-term operational planning.Polmar, Norman "The U. S. Navy Electronic Warfare (Part 1)" ''United States Naval Institute Proceedings'' October 1979 p.137 Thus, electronic support provides a source of information required for decisions involving electronic protection (EP), electronic attack (EA), avoidance, targeting, and other tactical employment of forces. Electronic support data can be used to produce signals intelligence (SIG ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

K Band (NATO)
The NATO K band is the obsolete designation given to the radio frequencies from 20 to 40 GHz (equivalent to wavelengths between 1.5 and 0.75 cm) during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA). However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training, electronic warfare Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults. The purpose of electronic warfare is to deny the opponen ... activities, or in military operations, this system is still in use. References {{EMSpectrum Microwave bands Satellite broadcasting ...

Fire-control Radar
A fire-control radar (FCR) is a radar that is designed specifically to provide information (mainly target azimuth, elevation, range and range rate) to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as targeting radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar. A typical fire-control radar emits a narrow, intense beam of radio waves to ensure accurate tracking information and to minimize the chance of losing track of the target. This makes them less suitable for initial detection of the target, and FCRs are often partnered with a medium-range search radar to fill this role. In British terminology, these medium-range systems were known as tactical control radars. Most modern radars have a track-while-scan capability, enabling them to function simultaneously as both fire-control radar and search radar. This works either by having t ...
