Kasturi-class Corvettes
The ''Kasturi''-class corvettes are two ships of the Royal Malaysian Navy, KD ''Kasturi'' and KD ''Lekir''. They were acquired in the mid-1980s. The two ships constitute the Royal Malaysian Navy's 22nd Corvette Squadron, their homeport being Lumut. After about 25 years of service, they underwent an extensive modernisation known as Service Life Extension Program (SLEP) starting in 2009, enabling them to be employed for another 10 to 15 years. They have since been returned to active duty. The two ships of the class are named after Hang Kasturi and Hang Lekir, two heroic figures from the Malay 15th-century epic narrative Hikayat Hang Tuah. They share this characteristic with the two s, KD ''Lekiu'' and KD ''Jebat'', as well as the old frigate-turned-training ship , all of which are named after figures from the epic as well. Development The class was ordered in February 1981 and built by the German Howaldtswerke-Deutsche Werft (HDW) shipyard. Both ships were simultaneously laun ...

Howaldtswerke-Deutsche Werft
Howaldtswerke-Deutsche Werft GmbH (often abbreviated HDW) is a German shipbuilding company, headquartered in Kiel. It is part of the ThyssenKrupp Marine Systems (TKMS) group, owned by ThyssenKrupp. The Howaldtswerke shipyard was founded in Kiel in 1838 and merged with Hamburg, Hamburg-based Deutsche Werft to form Howaldtswerke-Deutsche Werft (HDW) in 1968. The company's shipyard was formerly used by Friedrich Krupp Germaniawerft until the end of World War II. History HDW was founded October 1, 1838 in Kiel by engineer August Howaldt and entrepreneur under the name ''Maschinenbauanstalt und Eisengießerei Schweffel & Howaldt'' (Machine Factory and Iron Foundry Schweffel & Howaldt), initially building boilers. The first steam engine for naval purposes was built in 1849 for Von der Tann (gunboat), ''Von der Tann'', a gunboat for the small navy of Schleswig-Holstein. In 1850, the company built an early submarine, ''Brandtaucher'', designed by Wilhelm Bauer. It had been intended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KD Lekiu (FFG30)
KD ''Lekiu ''(FFG 30) is a guided missile frigate currently serving in the Royal Malaysian Navy and one of the major naval assets for Malaysia. Together with her sister ship KD Jebat (FFG29), ''Jebat'', ''Lekiu'' serves in the 23rd Frigate Squadron of the Royal Malaysian Navy. Development The ships were built by Yarrow Shipbuilders of Glasgow (now BAE Systems Surface Ships) of United Kingdom based on the F2000 frigate design. ''Lekiu'' was launched in December 1994 and commissioned May 1999. Although the ''Lekiu'' was launched before the ''Jebat'', but ''Jebat'' carries the lower pennant number (FFG29) compared to ''Lekiu'' (FFG30) to signify the seniority of this ship, which accommodates the Admiral of the Royal Malaysian Navy. (Hang Jebat succeeded Hang Tuah as ''Laksamana'' (Admiral) of the Malacca Sultanate, while Hang Lekiu was never made a ''Laksamana''.). Characteristic As for the weapon systems, ''Lekiu'' equipped with one Bofors 57 mm L/70 naval artillery gun, Bof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controllable Pitch Propeller
Controllability is an important property of a control system and plays a crucial role in many regulation problems, such as the stabilization of unstable systems using feedback, tracking problems, obtaining optimal control strategies, or, simply prescribing an input that has a desired effect on the state. Controllability and observability are dual notions. Controllability pertains to regulating the state by a choice of a suitable input, while observability pertains to being able to know the state by observing the output (assuming that the input is also being observed). Broadly speaking, the concept of controllability relates to the ability to steer a system around in its configuration space using only certain admissible manipulations. The exact definition varies depending on the framework or the type of models dealt with. The following are examples of variants of notions of controllability that have been introduced in the systems and control literature: * State controllability ...

Combined Diesel And Diesel
Combined diesel and diesel (CODAD) is a propulsion system for ships using two diesel engines to power a single propeller shaft. System A gearbox and clutches enable either of the engines or both of them together to drive the shaft. Two advantages over simply using a single, larger diesel engine of the same total power output are that (1) diesel engines have somewhat better specific fuel consumption at 75% to 85% max output than they do at only 50% output, and (2) there is a weight and size advantage to using two higher-speed engines compared to a single lower-speed engine, even with the slightly larger gearbox system.

Anti-submarine Mortar
Anti-submarine mortars are artillery pieces deployed on ships for the purpose of sinking submarines by a direct hit with a small explosive charge. They are often larger versions of the Mortar (weapon), mortar used by infantry and fire a projectile in relatively the same manner. They were created during World War II as a development of the depth charge and work on the same principle. Beginnings Anti-submarine warfare did not become an issue of great concern until World War I, when Germany used submarines in an attempt to strangle British shipping in the Atlantic Ocean and elsewhere. The earliest way to counter a submarine was in the form of depth charges, which were large canisters filled with explosives, rolled off the back of a ship and detonated by a hydrostatic fuze. Depth charges served well throughout World War I but were not without flaws. A ship had to pass directly over a submarine to score an effective hit, and as such, depth charges were dropped in lines instead of mor ...

Bofors 375mm Anti Submarine Rockets
The 375 mm ASW rocket family is an ahead-throwing anti-submarine rocket system developed by Bofors. The system has three types of launcher with either two, four, or six barrels, and entered service in the 1950s. Sweden used the four-barreled system on the and s. France built the four-barrelled system under licence then developed the six-barrel system and used it on many classes of warship including and destroyers and "A69" D'Estienne d'Orves-class avisos (corvettes). Turkey uses it on the Burak-class corvettes which are all former A69 class corvettes, mainly designed for coastal anti-submarine defense and ocean escort missions. The Netherlands used it in the s. It was also used by Royal Malaysian Navy on the s before they removed it from the ships. Indonesia use it on its three s and Brazil on six s, all of which are still in service.

French 100 Mm Naval Gun
Modern French 100 mm naval guns are multipurpose artillery pieces, capable of a high rate of fire, against both aerial and surface targets. Most modern French warships are or were equipped with one of its variants. History At the end of the Second World War, the French Navy was equipped with guns of numerous calibres, most of which were obsolete. In 1953, the STCAN of Paris, under engineer Tonnelé, drafted the design of a multi-purpose 100 mm gun. The gun was designed to be effective for anti-aircraft defence, anti-ship combat, and shore bombardment fire support. The first model of the family, "modèle 53", was tested at sea on the escort ''Le Brestois'' in 1958 and the escort aviso ''Victor Schoelcher'' in 1961. Description The most common version, ''modèle 68'', features a completely automatic action and control. The ammunition is stored in a magazine underneath the turret, and fed to the gun by a lift operated by a team of two. A flexible pipe allows feeding the ...

Jane's Fighting Ships
''Janes Fighting Ships'' is an annual reference book of each country's warship, navy and coast guard, along with their weapons and aircraft. Included are ship names, construction data, size, speed, range, complement, engineering, armament, and sensors. This is generally followed by relevant commentary. Originally, it was illustrated with ink sketches done by founder, Fred T. Jane (1865–1916). It is his surname "Jane" that makes this title distinctive. Jane was a struggling commercial artist and journalist with an interest in naval affairs. In the 1880s he set out to record all of the armored warships serving in the world's navies. His plan was to publish this record with the title ''Ironclads of the World''. Initially ''Brassey's Naval Annual'' and various Royal Navy periodicals were the source of inspiration for his drawings. In later years he became acquainted with a collector of warship photographs, W.A. Bieber. This enabled Jane to complete nearly 500 drawings. The fir ...
