The Sikorsky SH-60 Seahawk (or Sea Hawk) is a twin-engine multi-mission United States Navy helicopter based on the airframe of the United States Army/Air Force UH-60 Black Hawk.
The US Navy utilizes the H-60 airframe under the model designations SH-60B (Bravo), SH-60F (Foxtrot), HH-60H (Hotel), MH-60S (Sierra) and the MH-60R (Romeo) which is still in development. Able to deploy aboard any air-capable frigate, destroyer, cruiser, fast combat supply ship, amphibious assault ship or aircraft carrier the “Seahawk” provides multi-mission capabilities for the fleet. Missions include antisubmarine warfare (ASW), undersea warfare (USW), anti-surface warfare (ASUW), naval special warfare (NSW) insertion, search and rescue (SAR), combat search and rescue (CSAR), vertical replenishment (VERTREP) and medical evacuation (MEDEVAC). All Navy H-60s carry either the Lucas Western or Breeze Eastern rescue hoist for SAR/CSAR missions.
Models & Missions
The SH-60B (Bravo) Light Airborne Multi-Purpose System (LAMPS III) deploys primarily aboard frigates, destroyers and cruisers. The primary mission of the Bravo is 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. Other sensors include the APS-124 search radar and optional nose mounted forward looking infrared (FLIR) turret. The primary means of attack is with the Mk-46 torpedo and the capability of a single cabin door mounted M-60D or M-240 machine gun for defense. A standard crew for a Bravo is one pilot, one ATO/Co-Pilot(Aviation Tactical Officer) and an enlisted aviation systems warfare operator (sensor operator). Operating Bravo squadrons are designated Helicopter Antisubmarine Light (HSL).
The SH-60F (Foxtrot) is the carrier-based version of the Bravo. It is the primary means of antisubmarine warfare (ASW) and search and rescue (SAR) for carrier battle group commanders. It differs from the Bravo in means of submarine detection, utilizing the AQS-13F dipping sonar rather than a MAD detector and carrying fewer sonobuoys (12 vice 25). The Foxtrot is capable of carrying the Mk-46 torpedo and a choice of cabin-mounted guns including the M-60D, M-240 and GAU-16 machine guns 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). Operating Foxtrot squadrons are designated Helicopter Antisubmarine (HS).
The HH-60H (Hotel) 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 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 M-60D, M-240, GAU-16 and GAU-17 machine guns. 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.
The MH-60S (Sierra) was developed after the navy decided to phase out the venerable CH-46 Sea Knight helicopter. The Sierra is deployed aboard amphibious assault ships and fast combat supply ships. It has two missions- troop transports and vertical replenishment (VERTREP) but can also perform search and rescue (SAR). The Sierra has no offensive sensors but can carry the ALQ-199 Infrared Jammer. 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 three digital screens rather than electromechanical gauges and dials. The primary means of defense is with the M-60D, M-240 or GAU-17. 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).
The MH-60R (Romeo) is currently undergoing final testing for incorporation into the fleet. The first operational fleet squadron to receive the Romeo will be HSL-43 in fiscal year 2006. It is designed to replace the legacy Foxtrots and Bravos and provide a true multi-mission helicopter. Incorporated sensors include the ASE package, FLIR, an advanced airborne fleet data link system, the elimination of the MAD suite and incorporating a more advanced lightweight airborne sonar system (possibly the UYS-2A processor). Additional improvements will allow the Romeo to perform mine countermeasure operations using Light Imaging Detection and Ranging (LIDAR) laser technology. 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 Legacy Bravo/Foxtrot aircraft. Additionally attacking power is increased through the development of the new Mk-50 air launched torpedo and incorporating the HH-60H extended wing allowing four Hellfire missiles to be carried.
The SH-60 is in service with numerous allied naval forces including the Royal Australian Navy, the Hellenic (Greek) Navy and the Spanish navy.
