Sikorsky SH-60B Sea Hawk

Naval development of Sikorsky UTTAS (UH-60A Black Hawk) utility helicopter; won US Navy LAMPS Mk III competition for shipboard helicopter in 1977; first flight of first of five YSH-60B prototypes (161169) 12 December 1979; first 18 SH-60B authorised FY82. Changed USN planning in 1993 resulted in premature end to SH-60E/F production; original intent was to remanufacture SH-60B/P and HH-60H as SH-60R (redesignated MH-60R in mid-2001), but acquisition strategy changed in 2001 and most MH-60R will be new-build helicopters.

Most recent development, revealed in model form at Asian Aerospace, Singapore, February 2000, involves incorporation of external stores support system (ESSS) of UH-60/S-70A series, as well as MH-60R sensor suite. According to Sikorsky, this proposed version evolved in response to requests from potential customers in and around Pacific Rim, such as Indonesia, Malaysia and Singapore. If proceeded with; new version would have maximum take-off weight of around 11,340kg.

First flight (USCG 6001) 8 August 1989; first delivery to USCG (6002 at Elizabeth City CGAS) 16 June 1990; subsequently to Mobile, Traverse City, San Diego, Astoria, San Francisco, Cape Cod, Sitka, Kodiak and Clearwater CGAS. When carrying three 455 litre external tanks, HH-60J can fly out 556km and return with six survivors in addition to four-man crew, or loiter for 1 hour 30 minutes when investigating possible smugglers; other duties include law enforcement, drug interdiction, logistics, aids to navigation, environmental protection and military readiness; compatible with decks of 'Hamilton' and 'Bear' class USCG cutters. Equipment includes Honeywell RDR-1300C search/weather radar, AN/ARN-147 VOR/ILS, KDF 806 direction-finder, GPS, Tacan, VHF/UHF-DF, TacNav, dual U/UHF-FM radios, HF radio, IFF, V/U/HF IFF crypto computers, NVG-compatible cockpit, rescue hoist and external cargo hook.

  • XSH-60J: Japan Maritime Self-Defence Force (JMSDF) placed US$27 million order for two S-70B-3 for installation of Japanese avionics and mission equipment; first flights 31 August and early October 1987; 1,007 hour test programme by Japan Defence Agency-Technical Research and Development Institute between 1 June 1989 and 7 April 1991 to evaluate largely Japanese avionics for SH-60J, but AN/APS-124 radar.

  • SH-60J: Mitsubishi is manufacturing more than 100 SH-60J Seahawks for JMSDF.

  • SH-60K: Improved version of Seahawk for JMSDF; prototype rolled out 8 August 2001 and made first hover flight on 9 September 2001. Production was expected to begin in FY01 but has been delayed; JMSDF reportedly seeking initial batch of 50, with second batch of 50 to follow, as well as upgrade project involving SH-60J version.

  • MH-60R Strikehawk: Originally designated SH-60R and also known as LAMPS Block II; combines SH-60B capabilities with dipping sonar of SH-60F; original plan was for rebuild of existing fleet; first two conversions to be funded in FY98; 15 in FY99 and more thereafter; however, concerns over cost led to one year delay in launch of remanufacture programme, which began in FY00 with batch of four helicopters for test duties (ordered 25 April 2000) and was followed by five low-rate initial production (LRIP1) helicopters in FY01, also converted from existing airframes. Training unit HSL-41 at North Island, California, will be first squadron, with fleet introduction not now expected until late 2005.

    US Navy Helicopter Master Plan called for SH-60B, SH-60F and HH-60H to be included in the remanufacture programme. Development delays and cost concerns in 2000-01 prompted Navy to restructure programme with mostly new-build MH-60R, which will be purchased for US$1 million to US$3 million more than remanufactured examples and also allow the Navy to implement measures to improve power to weight performance. Of total 243 MH-60R required, only two prototypes and first nine "production" aircraft are remanufactured airframes.

    MH-60R systems orientated towards littoral warfare operations, with ability to process and prosecute large number of air and sea contacts in a comparatively confined space, the latter in relatively shallow water. New systems added to enhance countermeasures and passive and active detection capability. Initial upgrade package abandoned on grounds of high cost in 1998, when less costly programme, making extensive use of COTS technology, was adopted. Lockheed Martin secured US$61 million contract in third quarter of 1998 for development of common cockpit prototype applicable to MH-60R and MH-60S variant. Under terms of contract, Lockheed Martin provided flight instrument displays, two MFDs, two operator keysets and digital communications suite as well as Litton integrated INS/GPS, mass memory unit, mission and flight management computers and applicable operational software for both versions. New "glass cockpit" centred around Lockheed Martin-developed computer systems, but using commercial PowerPC processors, with data presented to pilots via electronic flight instrument display and multifunction mission display.

    Other changes on MH-60R include deletion of MAD, addition of AGM-114 Hellfire anti-armour missile and two additional stores stations, databus, Telephonics AN/APS-147 multimode radar, Raytheon/Thomson-Marconi Sonar AN/AQS-22 (FLASH) advanced airborne low-frequency dipping sonar, AN/AYK-14 mission processor and AN/UYS-2A enhanced modular signal processor. Lockheed Martin AN/ALQ-210 ESM, Raytheon AN/AAS-44 FLIR/laser ranger and NVG compatibility. MTOW expected tn rise to 10,659kg. May eventually be fitted with new, more powerful engine.

    Two SH-60B (162976 and 162977) selected as prototypes; conversion undertaken by Lockheed Martin Systems Integration at Owego, New York, where first (then designated SH-60R) was rolled out on 5 August 1999. First flight scheduled for October 1999, following electronic systems functional test and checkout on the gruund, but delayed until 11 December; first prototype half analogue/half 'glass cockpit' for initial testing, with full 'glass cockpit' installed after about three months. After initial trials at Owego, first prototype delivered to Patuxent River. Maryland, in early May 2000 for start of two-year Navy/contractor developmental test programme.

    Initial test aircraft (166402), remanufactured by Sikorsky, first flew 19 July 2001 and formally accepted by Navy (still in manufacturer's hands) later in same month. Subsequently to Patuxent River, Maryland, on 10 August 2001 for installation of flight test instrumentation and then to Lockheed Martin at Owego for fitting of new mission systems. First flight with 'total weapon system' made on 4 April 2002.

    All four test aircraft (166402 to '405) had been delivered to the Navy by the beginning of February 2002, with first of five LRIP1 MH-6OR (166406 to '410) flying on 9 July and being delivered to US Navy by end of that month. Further two LRIP1 machines were delivered in third quarter of 2002 and then allocated to Lockheed Martin at Owego for fitment of mission systems. Final hurdle before start of full-rate production is US Navy OpEval (operational evaluation), which began with VX-1 Squadron at Patuxent River in latter half of 2003. Successful conclusion of OpEval will clear way for Milestone III approval of full- rate production starting in FY05. Full funding of a second LRIP batch (of six new-build helicopters) will occur in FY04.

Exports comprise:

  • S-70B-1: Spanish Navy received six from December 1988 (designated HS.23) for operation from four FFG-7 frigates by Escuadrilla 010 at Rota; similar to USN SH-60B, but with Honeywell AN/ AQS-13F dipping sonar. Spanish government approval to order additional six granted in December 1998, with order placed in third quarter 2000; five of them delivered to Rota, in October 2002, with final aircraft retained at Owego, New York, tor additional trials. Deal for new helicopters also included funds to upgrade original six to same standard, including armament kits and compatibility with AGM-114 Hellfire and AGM-119 Penguin ASMs. First two upgraded helicopters were scheduled to be redelivered to Spanish Navy by October 2003.

  • S-70B-2: Royal Australian Navy (RAN) selected Seahawk for role adaptable weapon system (RAWS) full-spectrum ASW helicopter with autonomous operating capability; order for eight confirmed 9 October 1984; eight more ordered May 1996.

carrying two Penguin ASMs? Or is it only one such ASM on all the Naval Versions.

Alberto, devesayprado=terra.es, 26.12.2008

I'm an airplane from Spain, I am interested in making a mock-up of 2 meters over a HH60, this model can perform all the maneuvers performed by the real.

I ask if I could provide some sort of documentation or some simple drawings of external measures in order to make the model with the highest possible accuracy.

Thank you very much.

A greeting

FACTS AND FIGURES

Taiwan operates the S-70C(M)-1, equipped with new radar and torpedoes, from 'Kwang Hua I'-class frigates.

During the Gulf War two downed pilots were rescued by US Navy SH-60s.

Door-mounted machine-gun armament is often carried by US Navy SH/HH-60s.

A third version operated by the US Navy is the HH-60H (unofficially called 'Rescue Hawk') for the rescue of downed aircrew.

The US Coast Guard flies the HH-60J Jayhawk in the search-and-rescue role.

The only US Marine Corps H-60s are nine VH-60N 'Presidential Hawks' for VIPs.
