Nulka
Nulka is an Australian-designed and -developed active missile decoy built by an American/Australian collaboration. Used aboard warships of the United States Navy (USN), Royal Australian Navy (RAN), United States Coast Guard (USCG), and Royal Canadian Navy, Nulka is a rocket-propelled, disposable, offboard, active decoy designed to lure anti-ship missiles away from their targets. It has a unique design in that it hovers in mid-air while drawing the incoming anti-ship missile. The hovering rocket concept was initiated in Australia by the Defence Science and Technology Organisation (DSTO), and the system was designed, developed and then manufactured by AWA Defence Industries (AWADI) (now BAE Systems Australia). BAE refers to Nulka as a " soft-kill defence system". The word "Nulka" is of Australian Aboriginal origin and means "be quick". The Nulka consists of the missile itself enclosed in a hermetically sealed canister. This canister is then contained in a dedicated launcher module, ...

Mark 36 SRBOC
The BAE Systems Mark 36 Super Rapid Bloom Offboard Countermeasures Chaff and Decoy Launching System (abbreviated as SRBOC or "Super-arboc") is an American short-range decoy launching system (DLS) that launches radar or infrared decoys from naval vessels to foil incoming anti-ship missiles. The decoys present false signals and interference to the attacking missiles' guidance and fire-control systems. The Mark 36 SRBOC is similar to the Sea Gnat decoy system. The Mark 36 SRBOC uses the Mark 137 launcher, which has six fixed 130 mm mortar tubes arranged in two parallel rows. One row is set at 45 degrees and the other is set at 60 degrees, providing a spread of the launched decoys. Firing circuits use electromagnetic induction to set off the propelling charges in the decoy cartridges. They are launched at a speed of 75 m/s. Each launcher holds 12–36 rounds, depending on variant. The number and arrangement of Mk 36 launchers installed depends on the size of the ship, ranging fro ...

Naval Decoy IDS300
Naval Decoy IDS300 (Inflatable Decoy System) is a passive, off-board, octahedral, corner reflector decoy of the Royal Navy's Type 45 destroyer and the US Navy's destroyer, forming part of a layered defence to counter anti-ship missiles. Unlike chaff, the decoy is persistent and will float for up to three hours in sea state 4. Jane's was first to report the United Kingdom was looking for a new floating decoy as part of a program known as the Naval Passive Off-Board Decoy (N-POD), on March 3, 2019. In US Navy service, it is designated as the Mk 59 decoy launching system. The system is made by Irvin Aerospace Ltd, Hertfordshire in the United Kingdom. Deployment The decoy is launched out of a deck-mounted tube and self-inflates on the sea surface before being released to free-float past the stern to mimic a ship's radar and radio signatures. The deployment and inflation process takes seconds and the decoy is completely independent, requiring no further input from the ship. Typica ...

Anti-ship Missiles
An anti-ship missile (AShM) 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 good 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. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the ''Fritz X'', including the Italian battleship ''Roma'' and the light cruiser . A variant of the HS 293 had a TV camer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AWADI
AWA Technology Services, name based on former name Amalgamated Wireless (Australasia) Ltd, is an Australian provider for technology related services. Throughout most of the 20th century AWA was Australia's largest and most prominent electronics organisation, undertaking development, manufacture and distribution of radio, telecommunications, television and audio equipment as well as broadcasting services. After the sell-off of most of its assets and operating divisions, AWA is now primarily an information and communications technology (ICT) services company. History Pre-World War II The company commenced operations in 1909 as Australasian Wireless Limited (AWL), a Telefunken wireless agent. The first chairman was Hugh Denison. Ernest Fisk, a foundation director, was general and technical manager. In 1916 he became managing director and in 1932 chairman. The Marconi Company sued the Australian government in 1912, for infringing their patent (and AWL issued writs against firms u ...

Naval Warfare
Naval warfare is combat in and on the sea, the ocean, or any other battlespace involving a major body of water such as a large lake or wide river. Mankind has fought battles on the sea for more than 3,000 years. Even in the interior of large landmasses, transportation before the advent of extensive railroads was largely dependent upon rivers, canals, and other navigable waterways. The latter were crucial in the development of the modern world in Britain, the Low Countries and northern Germany, for they enabled the bulk movement of goods and raw materials without which the Industrial Revolution would not have occurred. Before 1800, war materials were largely moved by river barges or sea vessels and needed a naval defence against enemies. History Mankind has fought battles on the sea for more than 3,000 years.

Sonar Decoy
A sonar decoy is a device for decoying sonar. Most are released from submarines to act as a false target. Submarine decoys The first submarine decoys were the German Bold fitted to U-boats of World War II. These were a pellet of calcium hydride in a simple metal container. On contact with sea water, the calcium hydride decomposed to produce a trail of hydrogen gas bubbles that acted as a bubble curtain and reflected ASDIC impulses to produce a false target. The container trapped hydrogen and floated, with a crude spring valve to maintain buoyancy to keep it at a constant depth. Later decoys, such as Sieglinde, were motorised and could deploy their false target away from the host submarine, increasing safety. Torpedo decoys Decoys were also used by surface ships to decoy the developing acoustic torpedoes. These were usually towed behind the host. Example decoys Bubble decoys Reflective bubble targets * Bold * Sieglinde Hammer and explosive decoys These were intended ...

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.

Electronic Countermeasure
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 Blip enhancement is an electronic warfare technique used to fool radar. When the radar transmits a burst of energy some of that energy is reflected off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aegis Ballistic Missile Defense System
The Aegis Ballistic Missile Defense System (Aegis BMD or ABMD), also known as ''Sea-Based Midcourse'', is a United States Department of Defense Missile Defense Agency program developed to provide missile defense against short to intermediate-range ballistic missiles. The program is part of the United States national missile defense strategy and European NATO missile defence system. Aegis BMD is an expansion of the Aegis Combat System deployed on warships, designed to intercept ballistic missiles in post-boost phase and prior to reentry.

Houthi Insurgency In Yemen
The Houthi insurgency in Yemen, also known as the Houthi rebellion, the Sa'dah War, or the Sa'dah conflict, was a rebellion, military rebellion pitting Zaidiyyah, Zaidi Shia Islam, Shia Houthis (though the movement also includes Sunni Islam, Sunnis) against the Military of Yemen, Yemeni military that began in Northern Yemen and has since escalated into a Yemeni Civil War (2014–present), full-scale civil war. The conflict was sparked in 2004 by the government's attempt to arrest Hussein Badreddin al-Houthi, a Zaidi religious leader of the Houthis and a former parliamentarian on whose head the government had placed a $55,000 bounty. Initially, most of the fighting took place in Sa'dah Governorate in northwestern Yemen, but some of the fighting spread to neighbouring governorates Hajjah Governorate, Hajjah, 'Amran Governorate, 'Amran, Al Jawf Governorate, al-Jawf and the Saudi Jizan Region, province of Jizan. After the Houthi Battle of Sanaa (2014), takeover of the capital city Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
