ℹ️ ➖➖➖ 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. Able to deploy aboard any air-capable frigate, destroyer, cruiser, fast combat support ship, amphibious assault ship, littoral combat 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).
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. The MH-60R was formally deployed by the US Navy in 2006.
The MH-60R is designed to combine the features of the SH-60B and SH-60F. Its avionics includes dual controls and instead of the complex array of dials and gauges in Bravo and Foxtrot aircraft, 4 fully integrated 8" x 10" night vision goggle-compatible and sunlight-readable color multi-function displays, all part of glass cockpit produced by Owego Helo Systems division of Lockheed Martin. Onboard sensors include: AN/AAR-47 Missile Approach Warning System by ATK, Raytheon AN/AAS-44 electro-optical system that integrates FLIR and laser rangefinder, AN/ALE-39 decoy dispenser and AN/ALQ-144 infrared jammer by BAE Systems, AN/ALQ-210 electronic support measures system by Lockheed Martin, AN/APS-147 multi-mode radar/IFF interrogator, which during a mid-life technology insertion project is subsequently replaced by AN/APS-153 Multi-Mode Radar with Automatic Radar Periscope Detection and Discrimination (ARPDD) capability, and both radars were developed by Telephonics, a more advanced AN/AQS-22 advanced airborne low-frequency sonar (ALFS) jointly developed by Raytheon & Thales, AN/ARC-210 voice radio by Rockwell Collins, an advanced airborne fleet data link AN/SRQ-4 Hawklink with radio terminal set AN/ARQ-59 radio terminal, both by L3Harris, and LN-100G dual-embedded global positioning system and inertial navigation system by Northrop Grumman Litton division. Beginning in 2020, CAE's MAD-XR has been fielded on MH-60Rs, providing it with a magnetic anomaly detector.
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.
📑 ➖➖➖ Under Project AIR 9000 Phase 8, the MH-60R competed with the NHIndustries NH90 to replace the S-70B-2. In June 2011, the Defence Minister announced that the MH-60R had been selected to replace the S-70B-2. 24 MH-60Rs were ordered to be equipped with the Mark 54 and the Hellfire with deliveries commencing in mid-2014. The US had approved a Foreign Military Sale of 24 MH-60Rs in July 2010. The first MH-60R was delivered to the RAN in 2013 and the last was delivered in 2016. In 2018, Australia signed a 10-year agreement with the US Navy to support the MH-60R. The Department of Defence in the 2020 Force Structure Plan reported it planned to expand and rationalise the RAN's helicopter fleet. In October 2021, the US approved a Foreign Military Sale to Australia of 12 additional MH-60Rs.
