The Kaman SH-2G Super Seasprite is an American ship-based helicopter with anti-submarine , anti-surface threat capability, including over-the-horizon targeting. This aircraft extends and increases shipboard sensor and weapon capabilities against several types of enemy threats, including submarines of all types, surface ships , and patrol craft that may be armed with anti-ship missiles . It was originally developed for the United States Navy in the 1980s as a reengined and updated version of the older Kaman SH-2 Seasprite which had been serving since the 1960s in a variety of versions. The G model was an evolution of the SH-2F, which was an important ASW aircraft for naval vessels that could not manage a larger helicopter. The SH-2G entered service in the 1980s and served until 2001 with the U.S. Navy. It went on to serve in several other Naval forces into the 21st Century and is still in active service in several countries.
93-459: The SH-2G's primary missions include anti-submarine and anti-surface warfare, anti-ship missile defense, and anti-ship surveillance and targeting. Secondary missions may include medical evacuation, search and rescue, personnel and cargo transfer, as well as small boat interdiction, amphibious assault air support, gun fire spotting, mine detection and battle damage assessment. In 1985, the SH-2G program

(See military helicopter /maritime helicopters) This was an upgrade from the AQS-10 system carried aboard the SH-3A helicopter. The AQS-13 offered an improved reeling machine and longer cable or "wet-end" than the AQS-10. The "dry-end" components of
5859-468: The aircraft multifunction displays and/or recorded via the aircraft mission tape recorder. Due to the limited funding approved by Congress, the aircraft systems were limited to "off the shelf" technology wherever possible. This resulted in the use of a "dry-end" similar to the AQS-13E, even though more modern technology was available. The AQM-21/AQM-24 and AQM-24A Sonar Test Centrals were used at U.S. Navy shore stations and aboard Aircraft Carriers to support
5952-472: The armed helicopter modification kit and T700-401C engines with an option to purchase an additional six Seahawks and more engines. In 2011, Singapore bought six S-70Bs. In 2013, they ordered an additional two. In early 2015, Israel ordered eight ex-Navy SH-60Fs to support the expansion of the Israeli Navy surface fleet for ASW, ASuW and SAR roles. In 2015, Saudi Arabia requested the sale of ten MH-60R helicopters and associated equipment and support for
6045-404: The early 1980s. AQS-18(V) Later variations were sold as the AQS-18(V) to countries around the world. Individual variations are distinct to each customer and used aboard various platforms. Earlier versions shared higher degree of commonality with the German AQS-18 and later versions more with the USN's AQS-13F. Users include the Hellenic Navy (Greece) and the Portuguese Navy. The AQS-18 (V)-3
6138-421: The end of 2015. All the aircraft were in service by 2016. The NZDF's five SH-2G(NZ) Seasprites were officially retired on 14 April 2016, and conducted their last flight on 21 April after serving since August 2001. They were replaced with eight re-manufactured SH-2G(I) models, allowing the Navy to embark up to three helicopters from ships at once instead of two. The "I" model also replaces the AGM-65 Maverick with
6231-411: The fleet of five new SH-2G Super Seasprites were delivered. The Navy air element was transferred to No. 6 Squadron RNZAF at RNZAF Base Auckland in Whenuapai in October 2005. RNZN Seasprites have seen service in East Timor . New Zealand purchased five SH-2Gs at the same time as Australia. However, New Zealand opted for new-build airframes that were outfitted with different avionics. The SH-2G purchase
6324-514: The government would continue to support the Seasprite; Defence Minister Brendan Nelson commented that progress on the project was being closely monitored. Following the election of the new Labor government, The Australian reported on 31 January 2008 that the SH-2G(A) program was likely to be canceled due to cost overruns; additionally it was still not operational despite the original contract being signed in 1997. The same article also noted that Sikorsky had submitted an offer of several 'off
6417-429: The helicopters for $ NZ242 million was announced on 19 April 2013. Eight of the aircraft will enter service with the RNZAF to replace the existing five Seasprites, and the remaining two will be used as a source of spare parts. The New Zealand Ministry of Defence accepted the first of the helicopters in the United States on 1 December 2014, and two more were delivered to Auckland in early 2015. Deliveries were completed by
6510-444: The inner-zone ASW platform aboard aircraft carriers in the late-1980s/early-1990s. Key components of the AQS-13F system had origins in the made-for-export AQS-18 sonar developed for the German Navy for use in the Sea Lynx helicopter. The AQS-13F offered improved acoustic processing, a longer transmit pulse, faster reeling machine, longer cable and increased acoustic transmit power. The processed target data could also be displayed on
6603-456: 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. In February 2011, India selected the S-70B over the NHIndustries NH90 for an acquisition of 16 multirole helicopters for the Indian Navy to replace its aging Westland Sea King fleet. India selected the Seahawk for procurement in November 2014. In June 2017, India's Ministry of Defence terminated
6696-567: The mine, and is then instructed to shoot a shaped charge explosive to detonate it. In April 2016, BAE was awarded a contract to build and deliver the ROVs. The Navy received the first production SH-60B in February 1983 and assigned it to squadron HSL-41 . The helicopter entered service in 1984, and began its first deployment in 1985. The SH-60F entered operational service on 22 June 1989 with Helicopter Antisubmarine Squadron 10 (HS-10) at NAS North Island. SH-60F squadrons planned to shift from
6789-505: The mission. In early 1978, the Navy selected Sikorsky's S-70B design, which was designated "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. 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
6882-488: The navy's ASW needs. AQS-13 The AN/AQS-13 series was a helicopter dipping sonar system for the United States Navy . These systems were deployed as the primary inner zone anti-submarine warfare (ASW) sensor on aircraft carrier based helicopters for over five decades. Companion versions with the AQS-18 designation were exported to various nations around the globe. Airborne sonar systems provide
6975-416: The operator to achieve the maximum detection probability at the dip location on that particular day as determined by the study of ocean conditions (see Underwater Acoustics ). During active search, the acoustic pulse is emitted from the projector assembly. Echos or "returns" are received by the hydrophone , routed through the sonar cable, processed in the aircraft and displayed on a cathode ray tube (CRT) in
7068-660: The operators section of the SH-2 Seasprite . In the 1990s, the Royal Australian Navy (RAN) decided that it needed an intermediate helicopter to operate from the Anzac -class frigates and the planned offshore patrol vessel (OPV), a proposed cooperative project with Malaysia ; however, due to its size, the OPV could operate only a small helicopter. In 1997, the Australian Government signed
7161-536: 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 "Romeo" 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
7254-522: The power to safely tow the detection equipment. In 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
7347-600: The procurement program over a pricing issue. Then in August 2018, India's Defence Ministry approved the purchase of 24 MH-60R helicopters. In April 2019, the US Defense Security Cooperation Agency approved sale of 24 MH-60R anti-submarine helicopters to India for US$ 2.6 bn and notified Congress of the proposed sale. India signed a ₹ 15,157 crore (equivalent to ₹ 180 billion or US$ 2.1 billion in 2023) contract for

In April 2019, the US Defense Security Cooperation Agency approved a sale of 24 MH-60R anti-submarine helicopters to India for US$ 2.6 bn and notified Congress of the proposed sale. India signed a $ 2.13 billion (~$ 2.47 billion in 2023) (Rs 15,157 Crores) contract for the MH-60Rs in February 2020. These helicopters are to aid in detecting and destroying enemy submarines prowling in
7533-432: The reeling machine monitor the relative angle of the deployed sonar cable and provide flight reference signals to the aircraft stabilization equipment in order to maintain a steady hover position over the submerged transducer. Tactical data of the target is obtained from the acoustic returns, including range, bearing and relative speed. Later versions of the AQS-13 were also capable of processing acoustic signals transmitted to
7626-553: The shelf' helicopters to replace Australia's SH-2G(A)s. On 5 March 2008, the project was canceled by the government; Kaman noted the project's end "on mutually agreed terms". Opposition parties also supported the decision to cancel. The remaining aircraft were returned to Kaman. Following the cancellation of the Super Seasprite, S-70 Seahawks from 816 Squadron were assigned to the Anzac -class frigates. Australia already operated
7719-510: 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,
7812-475: The system remained essentially the same as the AQS-10. Developed in the 1950s, these components utilized primarily vacuum tube technology. The RO-358 chart recorder provided a means of recording a permanent record of target data as well as additional means for target evaluation. The AQS-13A system was an upgrade to the basic AQS-13 system incorporated into fleet systems in the late-1960s/early-1970s. The upgrade
7905-400: 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. An emergency flotation system was originally installed in the stub wing fairings of the main landing gear. It
7998-432: 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-13 F dipping sonar , and carried a 6-tube sonobuoy launcher. The SH-60F is unofficially named "Oceanhawk". The SH-60F can carry Mk 46 , Mk 50 , or Mk 54 torpedoes for its offensive weapons, and it has
8091-586: Was completed at NZ$ 12 million under the $ 338 million budgeted (excluding GST). The first RNZN SH-2G(NZ) was delivered in mid-2001, and the last was delivered February 2003. The Royal New Zealand Navy (RNZN) operates the type from its two Anzac -class frigates, two Protector-class offshore patrol vessels , and the multi-role vessel HMNZS Canterbury . They were initially operated by the Naval Support Flight of No. 3 Squadron RNZAF , but now from No. 6 Squadron RNZAF . An urgent operational need
8184-475: Was deployed to Desert Storm with HCS-4 and HCS-5 in 1991. The HH-60H's official DoD and Sikorsky name is Seahawk , though it has been called "Rescue Hawk". 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. These include a FLIR turret with laser designator, and
8277-564: Was for RNAF to use the FH MAG 58 machine gun on the helicopter, and this was fielded by 2008. In May 2012, Defence Minister Jonathan Coleman announced that Cabinet had given Defence officials approval to negotiate with Kaman Corporation for the 11 helicopters and flight simulator from the canceled Australian SH-2G(A) Super Seasprite project. It is thought the 11 helicopters, worth NZ$ 1.4 billion in 2008, would cost New Zealand between NZ$ 130 million to NZ$ 230 million. A decision to purchase ten of
8370-470: Was found to be impractical and possibly impeded emergency egress, and was 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 its first operational deployment in 1985. The SH-60B is deployed primarily aboard frigates , destroyers , and cruisers . The primary missions of
8463-551: Was primarily to incorporate built-in test equipment (BITE) circuitry, providing a method for testing system circuitry in the sonar set. The AQS-13B system was introduced to the US fleet as standard equipment aboard the Sikorsky SH-3H Sea King helicopter, replacing the SH-3D in the late-1970s. The AQS-13B was a significant upgrade from the AQS-13A. The "dry-end" components were replaced with solid state circuitry in
8556-925: Was redesignated MH-60R to match its multi-mission capability. The MH-60R was deployed by the US Navy in 2006. The MH-60R is designed to combine the features of the SH-60B and SH-60F.
