Laksamana-class Corvette
The Laksamana class is a class of small missile corvettes comprising four ships currently in service with the Royal Malaysian Navy. All four ships of the Laksamana class are currently serving in the 24th Corvette Squadron of the Royal Malaysian Navy. Development The Laksamana-class corvettes were originally purchased by the Iraqi Navy as the s, their delivery was delayed and later cancelled because of international sanctions against Iraq following the invasion of Kuwait by Iraq. It is based on the Fincantieri Type 550 corvette design. In October 1995, the Malaysian Ministry of Finance signed a contract with Italian company Fincantieri for the supply of two 675-ton missile corvettes for the Royal Malaysian Navy. Two more missile corvettes were ordered in February 1997. Some specific aspects of the ships' design were modified and the ships were refitted to meet the requirements of the Royal Malaysian Navy. The first two ships, named KD ''Laksamana Hang Nadim'' and KD ''Laksa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Admiral
Admiral is one of the highest ranks in some navies. In the Commonwealth nations and the United States, a "full" admiral is equivalent to a "full" general in the army or the air force, and is above vice admiral and below admiral of the fleet, or fleet admiral. Etymology The word in Middle English comes from Anglo-French , "commander", from Medieval Latin , . These evolved from the Arabic () – (), “king, prince, chief, leader, nobleman, lord, a governor, commander, or person who rules over a number of people,” and (), the Arabic article answering to “the.” In Arabic, admiral is also represented as (), where () means the sea. The 1818 edition of Samuel Johnson's '' A Dictionary of the English Language'', edited and revised by the Rev. Henry John Todd, states that the term “has been traced to the Arab. emir or amir, lord or commander, and the Gr. , the sea, q. d. ''prince of the sea''. The word is written both with and without the d, in other languages, as we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alenia Aeronautica
Alenia Aeronautica was an Italian aerospace company. Its subsidiaries included Alenia Aermacchi and Alenia Aeronavali. Alenia Aeronautica was also the part-owner of ATR, a joint venture with European Aeronautic Defence and Space Company (EADS). During January 2012, the company was reorganized as Alenia Aermacchi. Three years later, it was fully merged into Finmeccanica, which has since reorganised itself as a more integrated business, adopting the Leonardo name for the group History Alenia Aeronautica was created during 1990 by merger of IRI's Aeritalia and Selenia subsidiaries. The new company was associated with several ongoing aircraft programmes and partnerships, including the multinational Eurofighter Typhoon fighter programme, the Panavia Tornado fighter-bomber. As a partner in Panavia Aircraft GmbH, Aeritalia manufactured the Tornado's wings while the other partners (British Aerospace and MBB/DASA) manufactured the rest of the airframe.Segell 1997, p. 125.

Semi-active Radar Homing
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range Air-to-air missile, air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive radar, passive detector of a radar signal—Radar illumination, provided by an external ("offboard") source—as it reflects off the target (in contrast to active radar homing, which uses an active radar transceiver). Semi-active missile systems use bistatic radar, bistatic continuous-wave radar. The NATO Multiservice tactical brevity code, brevity code for a semi-active radar homing missile launch is Fox (code word), Fox One. Concept The basic concept of SARH is that since almost all detection and tracking systems consist of a radar system, duplicating this hardware on the missile itself is redundant. The weight of a transmitter reduces the range of any flying object, so passive systems have greater reach. In addition, t ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number.

Proximity Fuze
A proximity fuze (or fuse) is a Fuze (munitions), fuze that detonates an Explosive material, explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: * Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. ***Blast: A strong shock wave is provided by the detonation of the explosive. *** Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. *** Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag-shape ...

High-explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea-skimming
Sea skimming is a technique many anti-ship missiles and some fighter or strike aircraft use to avoid radar, infrared detection, and to lower probability of being shot down during their approach to the target. Method Sea-skimming anti-ship missiles try to fly as low as is practically achievable, which is almost always below 50 meters (150 ft), and is often down towards 2 meters (6 ft). When under attack, a warship can detect sea-skimming missiles only once they appear over the horizon (about 28 to 46 km from the ship), allowing about 25 to 60 seconds of warning. Advantages By flying low to the sea, missiles decrease the range at which the target ships can detect them by a significant amount. Flying at a lower altitude increases the amount of time the missile is under the horizon from the perspective of the target ship, making it harder to detect due to radar clutter from the sea and similar effects. The real-life success of sea skimming depends on its e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atlas Elektronik is a naval/marine electronics and systems business based in Bremen, Germany. It is involved in the development of integrated sonar systems for submarines and heavyweight torpedoes. The company was a subsidiary of BAE Systems until December 2005, when it was sold to ThyssenKrupp and EADS. Atlas Elektronik became a wholly owned subsidiary of ThyssenKrupp Marine Systems in 2017. History Early history The company was founded in 1902 as ''Norddeutsche Maschinen- und Armaturenfabrik GmbH'', focusing on shipbuilding and naval engineering services. Its name was changed in 1911 to ''Atlas Werke AG'', the origin of its modern-day name. During the First World War, Atlas Werke built U-boats for the Imperial German Navy. After the war, the company shrank in size and began to focus on civilian technology, due to restrictions imposed by the Treaty of Versailles. Following the Nazi seizure of power, the company grew to become an arms supplier for the Kriegsmarine. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. EW can be applied from air, sea, land, and/or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets. The electromagnetic environment Military operations are executed in an information environment increasingly complicated by the electromagnetic spectrum. The electromagnetic spectrum portion of the information environment is referred to as the electromagnetic environment (EME). The recognized need for military forces to have unimpeded access to and use of the electromagnetic environment creates vulnerabilities and opportunities for electronic warfare in support of military operations.
