HSL-49
Helicopter Maritime Strike Squadron 49 (HSM-49) is a United States Navy Maritime Strike helicopter squadron based Naval Air Station North Island, California. The ''Scorpions'' of HSM-49 are an operational fleet squadron based at NAS North Island. Their tailcode is TX and their radio callsign is "Red Stinger". The squadron provides combat-ready pilots, aircrewmen, technicians, and aircraft to Pacific Fleet warships. The squadron operates the MH-60R Seahawk helicopter. History HSM-49 was redesignated on 1 April 2015, formerly being Helicopter Anti-Submarine Squadron Light 49 (HSL-49). HSL-49 was established on 23 March 1990 as the U.S. Navy transitioned the Helicopter Anti-Submarine Light community from the SH-2 Seasprite to the SH-60B Seahawk. The ''Scorpions'' first deployed in November 1990 with Detachment 1 embarked in . The squadron - then and now - deploys its personnel and aircraft in an expeditionary model. Detachments are led by an Officer-in-Charge, normally a Lie ...

Anti-Submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ...

Magnetic Anomaly Detector
A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. The term refers specifically to magnetometers used by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field); military MAD equipment is a descendant of geomagnetic survey or aeromagnetic survey instruments used to search for minerals by detecting their disturbance of the normal earth-field. History Geoexploration by measuring and studying variations in the Earth's magnetic field has been conducted by scientists since 1843. The first uses of magnetometers were for the location of ore deposits. Thalen's "The Examination of Iron Ore Deposits by Magnetic Measurements", published in 1879, was the first scientific treatise describing this practical use. Magnetic anomaly detectors employed to detect submarines during World War II harnessed the fluxgate magnetometer, an inexpensive and easy to use t ...

Naval Aviation
Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases. Naval aviation is typically projected to a position nearer the target by way of an aircraft carrier. Carrier-based aircraft must be sturdy enough to withstand demanding carrier operations. They must be able to launch in a short distance and be sturdy and flexible enough to come to a sudden stop on a pitching flight deck; they typically have robust folding mechanisms that allow higher numbers of them to be stored in below-decks hangars and small spaces on flight decks. These aircraft are designed for many purposes, including air-to-air combat, surface attack, submarine attack, search and rescue, matériel transport, weather observation, reconnaissance and wide area command and control duties. Naval helicopters can be used for many of the same missions as fixed-wing aircraft while operating from aircraft carriers, helicopter carriers, destroyers and f ...

Vertical Replenishment
Vertical replenishment, or VERTREP, is a method of supply of seaborne vessels by helicopter. The United States Department of Defense defines VERTREP as: ...the transfer of cargo between ships using helicopters. VERTREP is often used to supplement connected replenishment. Weapons loads, generally limited to 1,800 kg (4,000 pounds), are transferred from the supply ship to the flight deck of the amphibious ship. The decided advantage of a VERTREP is that it can effect replenishment without ship-to-ship connection. History The United States Sixth Fleet had developed VERTREP routines in 1962 with SH-3 Sea King helicopters operating from and . Each ship carried one SH-3. At that time, there was some anticipation that nuclear-powered ships might reduce the need for alongside refueling. ''Altair'' performed the first night VERTREP to an aircraft carrier in 1965. Modern United States Navy VERTREP procedures were initiated from in November 1964. ''Sacramento'' embarked two CH-46 Sea Kn ...

M240D
The M240 – officially the Machine Gun, 7.62 mm, M240 – is the U.S. military designation for the FN MAG, a family of belt-fed, gas-operated medium machine guns that chamber the 7.62×51mm NATO cartridge. The M240 has been used by the United States Armed Forces since the late 1970s. It is used extensively by infantry, most often in rifle companies, as well as on ground vehicles, watercraft and aircraft. Though it is heavier than some comparable weapons, it is highly regarded for reliability and its standardization among NATO members is a major advantage. All variants are fed from disintegrating belts and are capable of firing most types of 7.62 mm (.30/.308 cal) NATO ammunition. M240 variants can be converted to use non-disintegrating belts. There are significant differences in weight and some features among some versions which restrict the interchangeability of parts. The M240s used by the U.S. military are currently manufactured by FN America, the American ...

GAU-21
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 ...

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 ...
