USS Independence (LCS-2)
USS ''Independence'' (LCS-2) is the lead ship of the of littoral combat ships. She is the sixth ship of the United States Navy to be named for the concept of independence. The design was produced by the General Dynamics consortium for the Navy's LCS program, and competes with the Lockheed Martin designed ''Freedom'' variant. ''Independence'', delivered to the Navy at the end of 2009, was a high speed, small crew corvette (although the U.S. Navy does not use the term) intended for operation in the littoral zone. She can swap out various systems to take on various missions, including finding and destroying mines, hunting submarines in and near shallow water, and fighting small boats (she is not intended to fight warships). The ship is a trimaran design with a wide beam above the waterline that supports a larger flight deck than those of the Navy's much larger destroyers and cruisers, as well as a large hangar and a similarly large mission bay below. The trimaran hull also exhibi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

M2 Browning
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...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 ...

Electronic Support Measures
In military telecommunications, electronic support (ES) or electronic support measures (ESM) gather intelligence through passive "listening" to electromagnetic radiations of military interest. They are an aspect of electronic warfare involving actions taken under direct control of an operational commander to detect, intercept, identify, locate, record, and/or analyze sources of radiated electromagnetic energy for the purposes of immediate threat recognition (such as warning that fire control RADAR has locked on a combat vehicle, ship, or aircraft) or longer-term operational planning.Polmar, Norman "The U. S. Navy Electronic Warfare (Part 1)" ''United States Naval Institute Proceedings'' October 1979 p.137 Thus, electronic support provides a source of information required for decisions involving electronic protection (EP), electronic attack (EA), avoidance, targeting, and other tactical employment of forces. Electronic support data can be used to produce signals intelligence (SIG ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
