Sikorsky SH-60 Seahawk

The Sikorsky SH-60/MH-60 Seahawk (or Sea Hawk) is a twin turboshaft engine, multi-mission United States Navy helicopter based on the United States Army UH-60 Black Hawk and a member of the Sikorsky S-70 family. The most significant modifications are the folding main rotor and a hinged tail to reduce its footprint aboard ships.

The U.S. Navy uses the H-60 airframe under the model designations SH-60B, SH-60F, HH-60H, MH-60R, and MH-60S. Able to deploy aboard any air-capable frigate, destroyer, cruiser, fast combat support ship, amphibious assault ship, or aircraft carrier, the Seahawk can handle anti-submarine warfare (ASW), 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).

Design and development


During the 1970s, the U.S. Navy began looking for a new helicopter to replace the Kaman SH-2 Seasprite.[3] The SH-2 Seasprite was used by the Navy as its platform for the Light Airborne Multi-Purpose System (LAMPS) Mark I avionics suite for maritime warfare and a secondary search and rescue capability. Advances in sensor and avionic technology lead to the LAMPS Mk II suite being developed by the Naval Air Development Center. The Navy then conducted a competition in 1974 to develop the Lamps MK III concept which would integrate both the aircraft and shipboard systems. The Navy selected IBM Federal Systems to be the Prime systems integrator for the Lamps MK III concept.

Since the SH-2 was not large enough to carry the Navy's required equipment a new airframe was required. In the mid-1970s, the Army evaluated the Sikorsky YUH-60 and Boeing Vertol YUH-61 for its Utility Tactical Transport Aircraft System (UTTAS) competition.[4] Navy based its requirements on the Army's UTTAS specification to decrease costs from commonality to be the new airframe to carry the Lamps MK III avionics.[3] Sikorsky and Boeing-Vertol submitted proposals for Navy versions of their Army UTTAS helicopters in April 1977 for review. The Navy also looked at helicopters being produced by Bell, Kaman, Westland and MBB, but these were too small for the mission. In early 1978 the Navy selected Sikorsky's S-70B design,[3] which was designated "SH-60B Seahawk".

SH-60B Seahawk

IBM was the prime systems integrator for the Lamps MK III with Sikorsky as the airframe manufacturer. The SH-60B maintained 83% commonality with the UH-60A.[5] The main changes were corrosion protection, more powerful T700 engines, single-stage oleo main landing gear, removal of the left side door, adding two weapon pylons, and shifting the tail landing gear 13 feet (3.96 m) forward to reduce the footprint for shipboard landing. Other changes included larger fuel cells, an electric blade folding system, folding horizontal stabilators for storage, and adding a 25-tube pneumatic sonobuoy launcher on the left side.[6] An emergency flotation system was originally installed in the stub wing fairings of the main landing gear; however, it was found to be impractical and possibly impede emergency egress, and thus was subsequently removed. Five YSH-60B Seahawk LAMPS III prototypes were ordered. The first YSH-60B flight occurred on 12 December 1979. The first production SH-60B made its first flight on 11 February 1983. The SH-60B entered operational service in 1984 with first operational deployment in 1985.[4]

The SH-60B is deployed primarily aboard frigates, destroyers, and cruisers. The primary missions of the SH-60B are surface warfare and anti-submarine warfare. It carries a complex system of sensors including a towed Magnetic Anomaly Detector (MAD) and air-launched sonobuoys. Other sensors include the APS-124 search radar, ALQ-142 ESM system and optional nose-mounted forward looking infrared (FLIR) turret. Munitions carried include the Mk 46, Mk 50, or Mark 54 Lightweight Torpedo, AGM-114 Hellfire missile, and a single cabin-door-mounted M60D/M240 7.62 mm (0.30 in) machine gun or GAU-16 .50 in (12.7 mm) machine gun.

A standard crew for a SH-60B is one pilot, one ATO/Co-Pilot (Airborne Tactical Officer), and an enlisted aviation warfare systems operator (sensor operator). The U.S. Navy operated the SH-60B in Helicopter Anti-Submarine Squadron, Light (HSL) squadrons. All HSL squadrons were redesignated Helicopter Maritime Strike (HSM) squadrons and transitioned to the MH-60R between 2006 and 2015.

The SH-60J is a version of the SH-60B for the Japan Maritime Self-Defense Force. The SH-60K is a modified version of the SH-60J. The SH-60J and SH-60K are built under license by Mitsubishi in Japan.[7][8]


After the SH-60B entered service,[9] the Navy conducted a competition to replace the SH-3 Sea King. The competitors were Sikorsky, Kaman and IBM (avionics only). Sikorsky began development of this variant in March 1985. In January 1986, seven SH-60Fs were ordered including two prototypes (BuNos 163282/3).[10] The first example flew on 19 March 1987.[11] The SH-60F was based on the SH-60B airframe, but with upgraded SH-3H avionics.

The SH-60F primarily served as the carrier battle group's primary antisubmarine warfare (ASW) aircraft. The helicopter hunted submarines with its AQS-13F dipping sonar, and carried a 6-tube sonobuoy launcher. The SH-60F is unofficially named "Oceanhawk".[11] The SH-60F can carry Mk 46, Mk 50, or Mk 54 torpedoes for its offensive weapons, and it has a choice of fuselage-mounted machine guns, including the M60D, M240D, and GAU-16 (.50 caliber) for self-defense. The standard aircrew consists of one pilot, one co-pilot, one tactical sensor operator (TSO), and one acoustic sensor operator (ASO). The SH-60F was operated by the U.S Navy's Helicopter Antisubmarine (HS) squadrons until they were redesignated Helicopter Sea Combat (HSC) squadrons transitioned to the MH-60S. The last HS squadron completed its transition in 2016.

The HH-60H was developed in conjunction with the US Coast Guard's HH-60J, beginning in September 1986 with a contract for the first five helicopters with Sikorsky as the prime contractor. The variant's first flight occurred on 17 August 1988. Deliveries of the HH-60H began in 1989. The variant earned initial operating capability in April 1990 and was deployed to Desert Storm with HCS-4 and HCS-5 in 1991.[11] The HH-60H's official DoD and Sikorsky name is Seahawk, though it has been called "Rescue Hawk".[12]

Based on the SH-60F, the HH-60H is the primary combat search and rescue (CSAR), naval special warfare (NSW) and anti-surface warfare (ASUW) helicopter. It carries various defensive and offensive sensors, it is 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. Engine exhaust deflectors provide infrared thermal reduction reducing the threat of heat-seeking missiles. The HH-60H can carry up to four AGM-114 Hellfire missiles on an extended wing using the M299 launcher and a variety of mountable guns including M60D, M240, GAU-16 and GAU-17/A machine guns.

The HH-60H's standard crew is pilot, copilot, an enlisted crew chief, and two door gunners or one rescue swimmer. Originally operated by HCS-5 and HCS-4 (later HSC-84), these two special USNR squadrons were established with the primary mission of Naval Special Warfare and Combat Search and Rescue (CSAR). Due to SOCOM budget issues the squadrons were deactivated in 2006 and 2016 respectively. The HH-60H was also operated by Helicopter Antisubmarine (HS) squadrons with a standard dispersal of six F-models and two or three H-models before the transition of HS squadrons to HSC squadrons equipped with the MH-60S, the last of which completed its transition in 2016. The only squadron equipped with the HH-60H as of 2016 is HSC-85, one of only two remaining USNR helicopter squadrons (the other being HSM-60 equipped with the MH-60R). In Iraq, HH-60Hs were used by the Navy, assisting the Army, for MEDEVAC purposes and special operations missions.

The MH-60R was originally known as "LAMPS Mark III Block II Upgrade" when development began in 1993 with Lockheed Martin (formerly IBM/Loral). Two SH-60Bs were converted by Sikorsky, the first of which made its maiden flight on 22 December 1999. Designated YSH-60R, they were delivered to NAS Patuxent River in 2001 for flight testing. The production variant was redesignated MH-60R to match its multi-mission capability.[13] The MH-60R was formally deployed by the US Navy in 2006.[14]

The MH-60R is designed to combine the features of the SH-60B and SH-60F.[15] Its sensors include the ASE package, MTS-FLIR, the AN/APS-147 multi-mode radar/IFF interrogator,[16] an advanced airborne fleet data link, and a more advanced airborne active low frequency sonar (ALFS). It does not carry the MAD suite. Pilot instrumentation is based on a fully integrated glass cockpit, using several digital monitors instead of the complex array of dials and gauges in Bravo and Foxtrot aircraft. 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 receive the Romeo are redesignated Helicopter, Strike Maritime (HSM) squadrons.[17] During a mid-life technology insertion project, the MH-60R fleet shall be fitted with the AN/APS-153 Multi-Mode Radar with Automatic Radar Periscope Detection and Discrimination (ARPDD) capability.[18]

The Navy decided to replace its venerable CH-46 Sea Knight helicopters in 1997. After sea demonstrations by a converted UH-60, the Navy awarded a production contract to Sikorsky for the CH-60S in 1998. The variant first flew on 27 January 2000 and it began flight testing later that year. The CH-60S was redesignated MH-60S in February 2001 to reflect its planned multi-mission use.[19] The MH-60S is based on the UH-60L and has many naval SH-60 features.[20] Unlike all other Navy H-60s, the MH-60S is not based on the original S-70B/SH-60B platform with its forward-mounted twin tail-gear and single starboard sliding cabin door. Instead, the S-model 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.[21][20] It also includes the integrated glass cockpit developed by Lockheed Martin for the MH-60R and shares some of the same avionics/weapons systems.

It is deployed aboard aircraft carriers, amphibious assault ships, Maritime Sealift Command ships, and fast combat support ships. Its missions include vertical replenishment, medical evacuation, combat search and rescue, anti-surface warfare, maritime interdiction, close air support, intelligence, surveillance and reconnaissance, and special warfare support. The MH-60S is to deploy with the AQS-20A Mine Detection System and an Airborne Laser Mine Detection System (ALMDS) for identifying submerged objects in coastal waters. It is the first US Navy helicopter to field a glass cockpit, relaying flight information via four digital monitors. The primary means of defense has been with door-mounted machine guns such as the M60D, M240D, or GAU-17/A. A "batwing" Armed Helo Kit based on the Army's UH-60L was developed to accommodate Hellfire missiles, Hydra 70 2.75 inch rockets, or larger guns. The MH-60S can be equipped with a nose-mounted forward looking infrared (FLIR) turret to be used in conjunction with Hellfire missiles; it also carries the ALQ-144 Infrared Jammer. photo essay 110617-F-HS649-048

The MH-60S is unofficially known as the "Knighthawk", referring to the preceding Sea Knight, though "Seahawk" is its official DoD name.[22][23] A standard crew for the MH-60S is one pilot, one copilot and two tactical aircrewmen depending on mission. With the retirement of the Sea Knight, the squadron designation of Helicopter Combat Support Squadron (HC) was also retired from the Navy. Operating MH-60S squadrons were re-designated Helicopter Sea Combat Squadron (HSC).[17] The MH-60S was to be used for mine clearing from littoral combat ships, but testing found it lacks the power to safely tow the detection equipment.[24]

On 6 August 2014, the U.S. Navy forward deployed the Airborne Laser Mine Detection System (ALMDS) to the U.S. 5th Fleet. The ALMDS is a sensor system designed to detect, classify, and localize floating and near-surface moored mines in littoral zones, straits, and choke points. The system is operated from an MH-60S, which gives it a countermine role traditionally handled by the MH-53E Sea Dragon, allowing smaller ships the MH-53E can't operate from to be used in the role. The ALMDS beams a laser into the water to pick up reflections from things it bounces off of, then uses that data to produce a video image for technicians on the ground to determine if the object is a mine.[25]

The MH-60S will utilize the BAE Systems Archerfish remotely operated vehicle (ROV) to seek out and destroy naval mines from the air. Selected as a concept in 2003 by the Navy as part of the Airborne Mine Neutralization System (AMNS) program and developed since 2007, the Archerfish is dropped into the water from its launch cradle, where its human operator remotely guides it down towards the mine using a fiber optics communications cable that leads back up to the helicopter. Using sonar and low-light video, it locates the mine, and is then instructed to shoot a shaped charge explosive to detonate it. BAE was awarded a contract to build and deliver the ROVs in April 2016, which will be delivered in September 2017.[26]

Operational history

U.S. Navy

The Navy received the first production SH-60B in February 1983 and assigned it to squadron HSL-41.[27][28] The helicopter entered service in 1984,[29] and began its first deployment in 1985.[27]

The SH-60F entered operational service on 22 June 1989 with Helicopter Antisubmarine Squadron 10 (HS-10) at NAS North Island.[19] SH-60F squadrons planned to shift from the SH-60F to the MH-60S from 2005 to 2011 and were to be redesignated Helicopter Sea Combat (HSC).[30]

As one of the two squadrons in the US Navy dedicated to Naval Special Warfare support and combat search and rescue, the HCS-5 Firehawks squadron deployed to Iraq for Operation Iraqi Freedom in March 2003. The squadron completed 900 combat air missions and over 1,700 combat flight hours. The majority of their flights in the Iraqi theater supported special operations ground forces missions.

A west coast Fleet Replacement Squadron (FRS), Helicopter Maritime Strike Squadron (HSM) 41, received the MH-60R aircraft in December 2005 and began training the first set of pilots. In 2007, the R-model successfully underwent final testing for incorporation into the fleet. In August 2008, the first 11 combat-ready Romeos arrived at HSM-71, a squadron assigned to the carrier John C. Stennis. The primary missions of the MH-60R are anti-surface and anti-submarine warfare. According to Lockheed Martin, "secondary missions include search and rescue, vertical replenishment, naval surface fire support, logistics support, personnel transport, medical evacuation and communications and data relay."[31]

HSL squadrons in the US have been incrementally transitioning to the MH-60R and have nearly completed the transition. The first MH-60Rs in Japan arrived in October 2012. The recipient was HSM-51, the Navy's forward–deployed LAMPS squadron, home based in Atsugi, Japan. The Warlords transitioned from the SH-60B throughout 2013, and shifted each detachment to the new aircraft as they returned from deployments. HSM-51 will have all MH-60R aircraft at the end of 2013. The Warlords are joined by the Saberhawks of HSM-77.

On 23 July 2013, Sikorsky delivered the 400th MH-60, an MH-60R, to the U.S. Navy. This included 166 MH-60R versions and 234 MH-60S versions. The MH-60S is in production until 2015 and will total a fleet of 275 aircraft, and the MH-60R is in production until 2017 and will total a fleet of 291 aircraft. The two models have flown 660,000 flight hours. Seahawk helicopters are to remain in Navy service into the 2030s.[32]

The SH-60B Seahawk completed its last active-duty deployment for the U.S. Navy in late April 2015 after a seven-month deployment aboard USS Gary. After 32 years and over 3.6 million hours of service, the SH-60B was formally retired from U.S. Navy service during a ceremony on 11 May 2015 at Naval Air Station North Island.[33][34] In late November 2015 USS Theodore Roosevelt returned from its deployment, ending the last active-duty operational deployment of both the SH-60F and HH-60H. The models are to be transferred to other squadrons or placed in storage.[35]

Air ambulance services in Greece

Air ambulance in Greece is air ambulance services provided by government agencies including the Hellenic Air Force or by private-sector companies.

The aircraft used by HAF for medical transportation are:

Agusta A109 helicopter

Lockheed C-130 Hercules

Alenia C-27J Spartan

Eurocopter AS332 Super Puma helicopterThe fixed-wing aircraft and the helicopters of the Hellenic Air Force, are ready 24 hours / 365 days a year and are called to transport from remote or hard to reach locations, patients or injured persons that need direct medical attention. The flights are coordinated in collaboration with the National Centre of Emergency Help (EKAB) and the Ministry of Health. During these missions, medical personnel are also on board.

The National Centre of Emergency Help (EKAB) also provides air ambulance services by means of other aircraft

Sikorsky SH-60 Seahawk Hellenic Navy helicopter

Aviation-capable naval vessels

Many present-day naval vessels, aside from aircraft carriers and full-length deck amphibious assault ships, are capable of carrying aircraft. A majority of United States Navy ships have at least a helipad, capable of landing medium-sized helicopters. Many others have decks and even hangars incorporated into the structure of the ship. It has become a standard part of modern ship design to have a deck that supports multiple, medium or large helicopters, as well as being able to house them in a hangar, for protection and maintenance. Aside from carriers and full-length deck amphibious assault ships, the US Navy has 12 classes of commissioned surface warships, 10 of which are aviation-capable. Two of those classes, patrol ships and mine counter-measure ships, are due to be replaced by the Littoral combat ship, at which point the entire US Naval surface war fleet will be aviation-capable.

Boeing Vertol YUH-61

The Boeing Vertol YUH-61 (company designation Model 179), was a twin turbine-engined, medium-lift, military assault/utility helicopter. The YUH-61 was the runner-up in the United States Army Utility Tactical Transport Aircraft System (UTTAS) competition in the early 1970s to replace the Bell UH-1 Iroquois helicopter. At the end of the flyoff program, Sikorsky Aircraft was awarded a contract to develop and build its UH-60A entry.

General Electric T700

The General Electric T700 and CT7 are a family of turboshaft and turboprop engines in the 1,500–3,000 shp (1,100–2,200 kW) class.

HTMS Chakri Naruebet

HTMS Chakri Naruebet (CVH-911) (Thai: จักรีนฤเบศร, meaning 'Sovereign of the Chakri Dynasty', the Thai monarchy's ruling family) is the flagship of the Royal Thai Navy (RTN), and Thailand's first and only aircraft carrier, although the RTN refers to her as an "Offshore Patrol Helicopter Carrier". Based on the Spanish Navy's Príncipe de Asturias design and constructed by Spanish shipbuilder Bazán, Chakri Naruebet was ordered in 1992, laid down in 1994, launched in 1996, and commissioned into the RTN in 1997. The ship is the smallest functioning aircraft carrier in the world.The aircraft carrier was designed to operate an air group of V/STOL fighter aircraft and helicopters, and is fitted with an aircraft ski-jump. Initial intentions were to operate a mixed air group of ex-Spanish AV-8S Matador Harrier V/STOL aircraft and Sikorsky SH-60 Seahawk helicopters. However, by 1999 it was reported that only one Matador was operational due to parts, training, and fiscal limitations, although three Matadors were spotted on the ship during a show of force after the 29 January 2003 Phnom Penh riots in Cambodia. Her entire Harrier V/STOL jet fleet was removed from service in 2006. Although Chakri Naruebet was intended for patrols and force projection in Thai waters, a lack of funding brought on by the 1997 Asian Financial Crisis meant the carrier has spent most of her career docked at the Sattahip naval base.

Chakri Naruebet has been deployed on several disaster relief operations, including in the aftermath of the 2004 Indian Ocean earthquake and tsunami, and in response to separate flooding incidents in late-2010 and early-2011. Other than disaster relief, the carrier's few other departures from port are for a single training day per month, and transportation of the Royal Family of Thailand, leading to claims by some naval commentators that the ship is merely an oversized royal yacht.

JMSDF Ōminato Base

JMSDF Ōminato Base (大湊基地, Ōminato Kichi) is a Japan Maritime Self-Defense Force naval base with port and military aerodrome (ICAO: RJSO) facilities. It is located on Mutsu Bay in the city of Mutsu in the Aomori Prefecture, in extreme northern Honshū, Japan.

Lockheed S-3 Viking

The Lockheed S-3 Viking is a 4-crew, twin-engine turbofan-powered jet aircraft used by the U.S. Navy (USN) primarily for anti-submarine warfare. In the late 1990s, the S-3B's mission focus shifted to surface warfare and aerial refueling. The Viking also provided electronic warfare and surface surveillance capabilities to a carrier battle group. A carrier-based, subsonic, all-weather, long-range, multi-mission aircraft; it carried automated weapon systems and was capable of extended missions with in-flight refueling. Because of its characteristic sound, it was nicknamed the "Hoover" after the vacuum cleaner brand.

The S-3 was phased out from front-line fleet service aboard aircraft carriers in January 2009. Its missions being taken over by aircraft like the P-3C Orion, Sikorsky SH-60 Seahawk and Boeing F/A-18E/F Super Hornet. Several aircraft were flown by Air Test and Evaluation Squadron Thirty (VX-30) at Naval Base Ventura County / NAS Point Mugu, California, for range clearance and surveillance operations on the NAVAIR Point Mugu Range until 2016 and one S-3 is operated by the National Aeronautics and Space Administration (NASA) at the NASA Glenn Research Center.

Mitsubishi H-60

The Mitsubishi H-60 series is twin-turboshaft engine helicopter based on the Sikorsky S-70 helicopter family for use by the Japan Self-Defense Forces (JSDF). The SH-60J/K are anti-submarine patrol versions for the Japan Maritime Self-Defense Force (JMSDF). The UH-60J is a search and rescue version for the Japan Air Self-Defense Force (JASDF) and JMSDF. The UH-60JA is a utility version for the Japan Ground Self-Defense Force (JGSDF).

Navalised aircraft

A navalised aircraft (or navalized aircraft) is an aircraft that has been specifically designed for naval use, in some cases as a variant of a land-based design. An aircraft based on an aircraft carrier is called carrier-based aircraft.

Piasecki X-49

The Piasecki X-49 "SpeedHawk" is an American four-bladed, twin-engined experimental high-speed compound helicopter developed by Piasecki Aircraft. The X-49A is based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and includes the addition of lifting wings. The concept of the experimental program was to apply the VTDP technology to a production military helicopter to determine any benefit gained through increases in performance or useful load.

"SpeedHawk" is a concept aircraft based on applying X-49A compounding concepts to a production UH-60 Black Hawk offering better performance, range, and increases in useful load. The "SpeedHawk" aircraft includes an SPU (third engine), high forward-swept wing concept, a 45-inch "fuselage plug" cabin extension, and several other drag reducing and performance-oriented improvements, including a rotor hub fairing, landing gear streamlining, and a fly-by-wire flight control system.

List of highways numbered 60, for State Route 60 or State Road 60

Sikorsky H-60

The Sikorsky H-60 is a family of military helicopters built by Sikorsky Aircraft.

All models use a modified mission symbol in addition to the 'H' vehicle type designator under the 1962 United States Tri-Service aircraft designation system (meaning, there is no aircraft named an "H-60" per se). The mission prefix (e.g. U, M, V) only has tangential meaning to the suffix series letter (A/B/C etc.), as most modified mission types encompass multiple series letters. Sikorsky also sells this helicopter as the S-70, but it was initially developed as the UH-60 to specific United States Army project requirements.

Variants include:

Sikorsky UH-60 Black Hawk, a medium-lift utility helicopter introduced in 1979.

Sikorsky SH-60 Seahawk, a multi-mission maritime helicopter used by the United States Navy.

Sikorsky SH-60F Oceanhawk, a variant for antisubmarine warfare.

Sikorsky MH-60S Knighthawk, a variant for troop transport and vertical replenishment, but can also perform search and rescue.

Sikorsky HH-60G Pave Hawk, a United States Air Force variant for combat search and rescue.

Sikorsky HH-60H Rescue Hawk, maritime special operations, search and rescue model for the U.S. Navy.

Sikorsky MH-60T Jayhawk, a variant used by the United States Coast Guard for maritime patrol, interdiction, and search and rescue (upgraded from extant HH-60J Jayhawk aircraft beginning in 2007).

Sikorsky VH-60N White Hawk, a variant used by the United States Marine Corps as Presidential and VIP transport helicopter including Marine One.

Mitsubishi H-60, manufactured in Japan by Mitsubishi under license from Sikorsky

Sikorsky MH-60 Jayhawk

The Sikorsky MH-60T Jayhawk is a multi-mission, twin-engine, medium-range helicopter operated by the United States Coast Guard for search and rescue, law enforcement, military readiness and marine environmental protection missions. Originally designated HH-60J before being upgraded and redesignated beginning in 2007, the MH-60T is designed to fly a crew of four up to 300 mi (483 km) offshore, hoist up to six additional people on board while remaining on-scene for up to 45 minutes and return to base while maintaining an adequate fuel reserve. Normal cruising speed of the MH-60T is 135 to 140 kn (155 to 161 mph) and the aircraft is capable of reaching 180 kn (207 mph) for short durations. The MH-60T can fly at 140 kn (161 mph) for six to seven hours.Chosen to replace the HH-3F Pelican, the MH-60T is a member of the Sikorsky S-70 family of helicopters and is based on the United States Navy's SH-60 Seahawk helicopter. Development began in September 1986, first flight was achieved on 8 August 1989, and the first HH-60J entered USCG service in June 1990. Production ended in 1996 after 42 helicopters were produced; three retired SH-60F Seahawks were also remanufactured to MH-60T specifications beginning in 2010. A total of 42 MH-60Ts are in service with the Coast Guard.

Special Patrol Insertion/Extraction

The Special Patrol Insertion/Extraction (SPIE) system was developed as a means to rapidly insert and/or extract a reconnaissance patrol from an area that does not permit a helicopter to land. SPIE has application for rough terrain as well as water inserts/extracts. It is an adaptation of the Vietnam War-era STABO rig.Generally, the SPIE rope is lowered into the pickup area from a hovering helicopter. Patrol personnel, each wearing a harness with an attached carabiner, hook up to a D-ring inserted in the SPIE rope. A second safety line is attached to a second D-ring located above the first. The helicopter lifts vertically from an extract zone until the rope and personnel are clear of obstructions, then proceeds in forward flight to a secure insert zone. The rope and personnel are treated as an external load and airspeeds, altitudes, and oscillations must be monitored.The United States Coast Guard uses a similar technique to board ships when speed and stealth are required.

USS Deyo

USS Deyo (DD-989), a Spruance-class destroyer, was a ship of the United States Navy named for Vice Admiral Morton L. Deyo (1887–1973), a veteran destroyerman and distinguished naval gunfire support task force commander of World War II.

Deyo was laid down on 14 October 1977 by Ingalls Shipbuilding, Pascagoula, Miss.; launched on 20 January 1979; and commissioned on 22 March 1980.

USS John Young

See also USS Young for similarly named ships.USS John Young (DD-973), named for Captain John Young USN, was a Spruance-class destroyer of the United States Navy. The ship was built by the Ingalls Shipbuilding Division of Litton Industries at Pascagoula, Mississippi.

USS Thorn (DD-988)

USS Thorn (DD-988), a Spruance-class destroyer, was the second ship of the United States Navy to be named for Lieutenant Jonathan Thorn (1779–1811), who took part in Decatur's expedition to destroy the captured frigate Philadelphia in 1804.Thorn was laid down on 29 August 1977 by Ingalls Shipbuilding, Pascagoula, Miss.; launched on 3 February 1979; and commissioned on 16 February 1980.Thorn was decommissioned and stricken from the Navy list on 25 August 2004.

Thorn was sunk as a test/target on 22 July 2006 off the US east coast.
