SH-60B Seahawk

The SH-60B Light Airborne Multi-Purpose System (LAMPS Mk III) deploys primarily aboard frigates, destroyers and cruisers, and, prior to the fleet introduction of the MH-60R "Romeo" (see section below), was considered the Navy's most advanced helicopter. Light Airborne Multi-Purpose System (LAMPS is the US Navy's program that developed manned Helicopters used to assist the surface fleet in Anti-submarine warfare For the bird see Frigatebird. A frigate /ˈfrɪgɪt/ is a warship In naval terminology a destroyer is a fast and maneuverable yet long-endurance Warship intended to escort larger vessels in a fleet, Convoy A cruiser is a large type of Warship, which had its prime period from the late 19th century to the end of the Cold War. There were five prototype YSH-60B Seahawks produced.

The primary missions of the B-model (or Bravo) are surface warfare and antisubmarine warfare, which it accomplishes through a complex system of sensors carried aboard the helicopter including a towed Magnetic Anomaly Detector (MAD) and air-launched sonobuoys. A magnetic anomaly detector (MAD is an instrument used to detect minute variations in the Earth's magnetic field. A sonobuoy (a Portmanteau of Sonar and Buoy) is a relatively small (typically 4⅞ inches or 124 mm in diameter and 36 inches or 910 mm long expendable Other sensors include the APS-124 search radar, ALQ-142 ESM system and optional nose-mounted forward looking infrared (FLIR) turret. A forward looking infrared (FLIR is an imaging device that senses infrared radiation It carries the Mk-46, Mk-50, or Mk-54 torpedo, AGM-114 Hellfire missile, and a single cabin-door-mounted M60D or GAU-16 machine gun. Designed to attack high-performance submarines the Mark 46 Torpedo is the backbone of the U The Mark 50 torpedo is a US Navy advanced lightweight Torpedo for use against fast deep-diving submarines. The modern torpedo (historically called an automotive automobile locomotive or fish torpedo is a self-propelled explosive Projectile weapon launched above or below The AGM-114 Hellfire is a multi-platform multi-target United States modular Missile system

A standard crew for a Bravo is one pilot, one ATO/Co-Pilot (Airborne Tactical Officer) and an enlisted aviation systems warfare operator (sensor operator). Operating Bravo squadrons are designated Helicopter Antisubmarine Light (HSL). HSL-47, an SH-60B squadron based at Naval Air Station North Island in Coronado, California, participated in the Navy's humanitarian relief operations during the 2004 Indonesian Tsunami and Hurricane Katrina. The 2004 Indian Ocean earthquake was an undersea Earthquake that occurred at 005853 UTC on December 26 2004 with an Epicentre off the west coast of Hurricane Katrina of the 2005 Atlantic hurricane season was the costliest hurricane, as well as one of the five deadliest in the history of the United States ^[1]

SH-60F Oceanhawk

The SH-60F is the carrier-based version of the Bravo, having replaced the SH-3 Sea King as the carrier battle group's primary antisubmarine warfare (ASW) and search and rescue (SAR) aircraft. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout It hunts subs with the AQS-13F dipping sonar, not the Bravo's MAD detector, and carries just 14 sonobuoys, instead of the Bravo's 25. Sonar (which started as an Acronym for sound navigation and ranging) is a technique that uses Sound propagation (usually underwater to navigate

The F-model (or Foxtrot) carries the Mk-46 torpedo and a choice of cabin-mounted machine guns, including the M60D, M240 and GAU-16, for defense. A standard crew for the Foxtrot is one pilot, one copilot, one enlisted tactical sensor operator (TSO) and one enlisted acoustic sensor operator (ASO). Foxtrot squadrons are designated Helicopter Antisubmarine (HS), but as squadrons shift from the SH-60F to the MH-60S beginning in 2007, they will be redesignated Helicopter Sea Combat (HSC).

HH-60H "Rescue Hawk"

The HH-60H is the primary combat search and rescue (CSAR), naval special warfare (NSW) and anti-surface warfare (ASUW) helicopter. It carries a variety of defensive and offensive sensors making it one of the most survivable helicopters in the world. Sensors include a FLIR turret with laser designator and the Aircraft Survival Equipment (ASE) package including the ALQ-144 Infrared Jammer, AVR-2 Laser Detectors, APR-39(V)2 Radar Detectors, AAR-47 Missile Launch Detectors and ALE-47 chaff/flare dispensers. Additionally, airframe improvements in engine exhaust deflectors provide infrared thermal reduction reducing the threat of heat-seeking missiles. The H-model (or Hotel) can carry up to four AGM-114 Hellfire missiles on an extended wing using the M-299 launcher and a variety of cabin and port window mounted guns including M60D, M240, GAU-16 and GAU-17/A machine guns. The AGM-114 Hellfire is a multi-platform multi-target United States modular Missile system The M60 (formally the United States Machine Gun Caliber 762 mm M60) is a family of American General purpose machine guns firing 7 This article is about the.50 caliber M2 machine gun For the.30-06 M2 machine gun see M1919 Browning machine gun. The minigun is a multi-barrel Machine gun with a high rate of fire (several thousand Rounds per minute) employing Gatling -style rotating barrels and an The standard crew for a Hotel is one pilot, one copilot, and two "door gunner" crewmen. Hotels are operated in Helicopter Antisubmarine (HS) squadrons with a standard dispersal of four Foxtrots and three Hotels.

MH-60S Knighthawk

The MH-60S was developed after the Navy decided to phase out the venerable CH-46 Sea Knight helicopter. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The S-model (or Sierra) is deployed aboard amphibious assault ships and fast combat supply ships. An amphibious assault ship (also referred to as an amphibious assault carrier or commando carrier) is a type of Helicopter carrier employed to land The fast combat support ship (AOE is the United States Navy 's largest combat logistics ship designed as an oiler ammunition and supply ship It has two missions- troop transports and vertical replenishment (VERTREP) but can also perform search and rescue (SAR). VERTREP is an abbreviation for Vertical replenishment. This refers to aerial supply of seaborne vessels by Helicopter. The Sierra has no offensive sensors but can carry the ALQ-144 Infrared Jammer. The Sierra will, in the near future, deploy with the AQS-20A Mine Detection System and an Airborne Laser Detection system for identifying submerged objects in coastal waters. The AQS-20A is an airborne SONAR mine countermeasure detection system developed by Raytheon. However, the Sierra is the first US Navy helicopter to field the glass cockpit where-by the flight data information is relayed to pilots using four digital screens rather than electromechanical gauges and dials. A glass cockpit is an Aircraft cockpit that features electronic instrument displays. In Engineering, electromechanics combines the Sciences of Electromagnetism of Electrical engineering and mechanics.

The primary means of defense is with the M60D, M240 or GAU-17, a 'batwing' refit (Armed Helo Kit) based on the Army's UH-60L Black Hawk was developed to accommodate Hellfire or Penguin missiles, or larger guns and cannon. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout The AGM-114 Hellfire is a multi-platform multi-target United States modular Missile system The Penguin Anti-ship missile (US designation AGM-119) made by Kongsberg Defence & Aerospace (KDA of Norway from the early 1970s and continually MH-60S was unofficially known as the Knighthawk, reflecting its role as the designated successor of the Sea Knight, but this name was formally disapproved allowing the MH-60S to retain the Seahawk name. A standard crew for the Sierra is one pilot, one copilot and two crewmen. With the retirement of the Sea Knight the squadron designation of Helicopter Combat Support Squadron (HC) was also retired from the navy. Operating Sierra squadrons were re-designated Helicopter Sea Combat (HSC).

Unlike all other Navy H-60s, the MH-60S is not based on the original S-70B platform with its forward-mounted twin tail-gear and single starboard sliding cabin door. Instead, the Sierra is a hybrid, featuring the main fuselage of the S-70A/UH-60, with large sliding doors on both sides of the cabin and a single aft-mounted tail wheel; and the engines, drivetrain and rotors of the S-70B/SH-60.

MH-60R Seahawk

As of 2007, the MH-60R is undergoing final testing for incorporation into the fleet. The first operational fleet squadron to receive the Romeo will be HSM-71 in fiscal year 2008. The Fleet Replacement Squadron (FRS), HSM-41, received the R-model (or Romeo) aircraft in December 2005 and has begun training the first set of pilots. It is designed to replace Foxtrots and Bravos and be a true multi-mission helicopter. Its sensors include the ASE package, MTS-FLIR, an advanced airborne fleet data link, and a more advanced airborne active sonar. It does not carry the MAD suite. Pilot instrumentation will be based on the Sierra’s “glass cockpit” using several digital monitors instead of the complex array of dials and gauges in Bravo and Foxtrot aircraft. A glass cockpit is an Aircraft cockpit that features electronic instrument displays. Offensive capabilities are improved by the addition of new Mk-54 air-launched torpedoes and Hellfire missiles. All Helicopter Anti-Submarine Light (HSL) squadrons that will receive the Romeo will be redesignated Helicopter Maritime Strike (HSM).
