Independence-class Littoral Combat Ship
The ''Independence'' class is a class of littoral combat ships built for the United States Navy. The hull design evolved from a project at Austal to design a high speed, 40-knot-cruise ship. That hull design evolved into the high-speed trimaran ferry and the ''Independence'' class was then proposed by General Dynamics and Austal as a contender for Navy plans to build a fleet of smaller, agile, multipurpose warships to operate nearshore in the littoral zone. Initially two ships were approved, to compete with Lockheed Martin's design. Despite initial plans to only build ships of the winner out of the two competing ''Independence'' or ''Freedom'' classes, in 2010 the Navy announced plans to order up to ten additional ships of each class, for a total 12 ships per class. In March 2016 the Navy announced their intention to order an additional two ships, increasing the order to 13 ships of each class. It was announced in early September 2016 that the first four vessels of the LCS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austal USA
Austal USA is an American shipbuilder based on Blakeley Island in Mobile, Alabama. It is a subsidiary of the Australian shipbuilder Austal, operating under a Special Security Arrangement which allows it to work independently and separately on some of the most sensitive United States defense programs despite its foreign ownership. Austal USA was formed in 1999 when Austal formed a 70:30 joint venture with Bender Shipbuilding & Repair Co to build ferries. Austal bought out its partner in September 2006. Notable projects for the shipbuilder include the United States Navy's ''Independence'' class littoral combat ship (first launched in 2008) and United States Coast Guard's ''Heritage''-class cutter (contract awarded in 2022). Projects Austal USA's first contract was for two crew supply vessels for service in the Gulf of Mexico. These were followed by a ferry for Lighthouse Fast Ferry of New York. Austal USA built the ''Lake Express'' for service across Lake Michigan, and the ''A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FLIR
Forward-looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation. The sensors installed in forward-looking infrared cameras, as well as those of other thermal imaging cameras, use detection of infrared radiation, typically emitted from a heat source (thermal radiation), to create an image assembled for video output. They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect is 3 to 12 μm and differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm). Design Infrared light falls into two basic ranges: ''long-wave'' and ''medium-wave''. Long-wave infrared (LWIR) cameras, sometimes called "far-infrared", operate at 8 to 12 μm and can see heat sources, such as hot e ...

Mk44 Bushmaster II
The Mk44 Bushmaster II is a 30 mm chain gun manufactured by Northrop Grumman. It is a derivative of the 25 mm M242 Bushmaster, and uses 70% of the same parts as the M242 while increasing the firepower by as much as 50% with the 20% increase in caliber size. The barrel is chromium-plated for extended life. The gun uses standard GAU-8 Avenger ammunition that is available in API (Armor-Piercing Incendiary), HEI (High-Explosive Incendiary) and APFSDS-T (Armor-Piercing Fin-Stabilized Discarding Sabot-Tracer) variants. The gun can be converted to a caliber of 40x180 mm, which involves changing the barrel and a few key parts, to use the SuperShot 40 cartridge. It can also be converted to use the 30x170 mm RARDEN cartridge. History The Bushmaster II is the standard primary armament of the Bionix-II AFV currently in service with the Singapore Army, the KTO Rosomak in Polish service, and the CV90 AFVs in Finnish, Norwegian and Swiss service.

CIWS
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Examples of g ...

SeaRAM
The RIM-116 Rolling Airframe Missile (RAM) is a small, lightweight, infrared homing surface-to-air missile in use by the German, Japanese, Greek, Turkish, South Korean, Saudi Arabian, Egyptian, Mexican, UAE, and U.S. Navies. It was originally intended and used primarily as a point-defense weapon against anti-ship missiles. As its name indicates, RAM rolls as it flies. The missile must roll during flight because the RF tracking system uses a two-antenna interferometer that can measure phase interference of the electromagnetic wave in one plane only. The rolling interferometer permits the antennas to look at all planes of incoming energy. In addition, because the missile rolls, only one pair of steering canards is required. , it is the only U.S. Navy missile to operate in this manner. The Rolling Airframe Missiles, together with the Mk 49 Guided Missile Launching System (GMLS) and support equipment, make up the RAM Mk 31 Guided Missile Weapon System (GMWS). The Mk-144 Guided Miss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mk 110 57 Mm Gun
Bofors 57 mm Naval Automatic Gun L/70 ( sv, 57 mm sjöautomatkanon L/70 (''57 mm SAK 70'')), among other names (see Names), is a series of dual-purpose naval guns designed and produced by the Swedish arms manufacturer AB Bofors (since March 2005 part of BAE Systems AB), designed in the late 1960s as a replacement design for the twin barreled Bofors 57 mm Naval Automatic Gun L/60. The gun is remotely controlled by a fire-control computer but can as a redundancy measure also be operated manually by crew using instrument panels either on or in direct contact with the gun. The gun has been upgraded and improved several times: *Mk1 – The baseline Mark 1 variant began production in 1970 and was initially used to equip smaller coastal patrol craft and fast attack craft. *Mk2 – The improved Mark 2 variant came in 1981 and drastically lowered the weight as well as introduced new servo stabilizers. *Mk3 – The improved Mark 3 variant came in 1995 and primarily features the ...

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, ...

Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaff (radar Countermeasure)
Chaff, originally called Window by the British and ''Düppel'' by the Second World War era German Luftwaffe (from the Berlin suburb where it was first developed), is a radar countermeasure in which aircraft or other targets spread a cloud of small, thin pieces of aluminium, metallized glass fibre or plastic, which either appears as a cluster of primary targets on radar screens or swamps the screen with multiple returns, in order to confuse and distract. Modern armed forces use chaff (in naval applications, for instance, using short-range SRBOC rockets) to distract radar-guided missiles from their targets. Most military aircraft and warships have chaff dispensing systems for self-defense. An intercontinental ballistic missile may release in its midcourse phase several independent warheads as well as penetration aids such as decoy balloons and chaff. Modern radar systems can distinguish chaff from target objects by measuring the Doppler shift; chaff quickly loses speed compared t ...

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 ...
