German Frigate Brandenburg
''Brandenburg'' is a ''Brandenburg''-class frigate of the German Navy, and the lead ship of her class. Construction and commissioning ''Brandenburg'' and the three other frigates of the ''Brandenburg'' class were designed as replacements for the ''Hamburg''-class destroyers. She was laid in 1992 at the yards of Blohm+Voss, Hamburg and launched in August 1992. She was christened by Ingrid Stolpe, the wife of the then Minister-President of Brandenburg Manfred Stolpe. After undergoing trials she was commissioned on 14 October 1994, and assigned to ''6. Fregattengeschwader''. After the naval structure was reorganised, ''Brandenburg'' was assigned to ''2. Fregattengeschwader'', based at Wilhelmshaven. Service ''Brandenburg'' spent some time in 2006 assigned to the maritime element of the United Nations Interim Force in Lebanon, serving as the flagship of the maritime taskforce commander Flotilla Admiral Andreas Krause. On 30 November 2006 she was visited by Foreign Minister Fran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antiaircraft Warfare
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, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mauser BK-27
The BK 27 (also BK27 or BK-27) (German abbreviation for ''Bordkanone'', "on-board cannon") is a caliber revolver cannon manufactured by Mauser (now part of Rheinmetall) of Germany. It was developed in the late 1960s for the MRCA (Multi Role Combat Aircraft) program that ultimately became the Panavia Tornado. The BK 27 is a gas-operated cannon firing a series of 27×145 mm cartridges with a typical projectile weight of 260 g (9.2 oz), and a total weight for the complete round of 516 g (1.14 lb). Most models use a linked feed system for the ammunition; however, the Eurofighter Typhoon makes use of a specially developed variant of the BK 27 that uses a linkless feed system instead, which is intended to improve reliability. Design The Mauser BK 27 is used in the Panavia Tornado, the Alpha Jet, the JAS 39 Gripen, and the Eurofighter Typhoon. At one time Lockheed Martin was considering a licensed-built version for the F-35 Lightning II. Rheinmetall has als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otobreda 76 Mm
The OTO Melara 76 mm gun, marketed as the OTO 76/62 Gun Mount, is a naval autocannon 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 maneuvering 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 favored over the French 100mm naval gun for the joint French/Italian project and FREMM frigate. The Super Rapid Gun Mount (SRGM) variant is being license-manufactured in India by Bharat Heav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decoy
A decoy (derived from the Dutch ''de'' ''kooi'', literally "the cage" or possibly ''eenden 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 ...

MASS (decoy System)
Multi Ammunition Softkill System (MASS) is a naval self-defence system produced by Rheinmetall of Germany. It is connected to the ship's sensors and protects ships from attacks by advanced sensor-guided missiles by launching decoys that operate in all relevant wavelengths of the electromagnetic spectrum: ultraviolet, electro-optical, laser, infrared and radar. MASS can either be integrated with the command and control system of a warship, or can operate autonomously. Rheinmetall Defence stated that "MASS has attracted orders from 9 nations, for 130 launchers, on 15 different classes of naval vessels" as of 31 March 2009. As of 3 March 2011, this has been expanded to a total order of at least 172 units. Roughly one year later, on 17 April 2012, the total was 186 launchers for 22 different classes of vessels in 11 different nations.

Oto Melara
OTO Melara was a subsidiary of the Italian company Finmeccanica, today Leonardo, active in the defence sector, with factories in Brescia and La Spezia. From 1 January 2016, the activities of OTO Melara merged into Leonardo's Defence Systems Division, within the Electronics, Defence and Security Systems Sector. History Pre–World War I It was founded in 1905 as a joint venture of Vickers and Terni Steelworks, Cantiere navale fratelli Orlando and Cantieri navali Odero. Investment was also provided by Giuseppe Orlando and Attilio Odero. During World War I, Vickers Terni produced many weapons with calibre 40 mm and upwards. In 1929 the company was renamed Odero Terni Orlando with the abbreviation OTO. During World War II, mostly heavy guns for battleships were produced. Post–World War II In 1953 the company took the name OTO Melara. Before Italy joined NATO, OTO Melara produced civil products, like tractors and looms, but quickly returned to the production of wea ...

Electronic Countermeasures
An electronic countermeasure (ECM) is an electrical or electronic device designed to countermeasure, 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 Radar jamming, jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile guidance, missile terminal homers. History The first example of electronic countermeasures being a ...

EADS
Airbus SE ( ; ; ; ) is a Pan-European aerospace corporation. The company's primary business is the design and manufacturing of commercial aircraft but it also has separate defence and space and helicopter divisions. Airbus has long been the world's leading helicopter manufacturer and, in 2019, also emerged as the world's biggest manufacturer of airliners. The company was incorporated as the European Aeronautic Defence and Space Company (EADS) in the year 2000 through the merger of the French Aérospatiale-Matra, the German DASA and Spanish CASA. The new entity subsequently acquired full ownership of its subsidiary, ''Airbus Industrie GIE'', a joint venture of European aerospace companies originally incorporated in 1970 to develop and produce a wide-body aircraft to compete with American-built airliners. EADS rebranded itself as ''Airbus SE'' in 2015. Reflecting its multinational origin, the company operates major offices and assembly plants in France, Germany, Spain, and ...

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 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) to e ...
