The Sikorsky SH-60/MH-60 Seahawk is a twin turboshaft engine,
multi-mission helicopter based on the United States Army UH-60 Black
Hawk and a member of the Sikorsky S-70 family. The US 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 ship, 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: AAR-47 Missile Approach Warning System by ATK,Raytheon AAS-44 electro-optical system that integrates FLIR and laser rangefinder, ALE-39 decoy dispenser and ALQ-144 infrared jammer by BAE Systems, ALQ-210 electronic support measures system by Lockheed Martin, APS-147 multi-mode radar/IFF interrogator, which during a mid-life technology insertion project is subsequently replaced by 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, ARC-210 voice radio by Rockwell Collins, an advanced airborne fleet data link SRQ-4 Hawklink with radio terminal set 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. The Royal Danish Navy (RDN) put the MH-60R on a short list for a requirement of around 12 new naval helicopters, together with the NH90/NFH, H-92, AW159 and AW101. The Request For Proposal was issued on 30 September 2010. In November 2010, Denmark requested approval for a possible purchase of 12 MH-60Rs through a Foreign Military Sale. In November 2012, Denmark selected 9 MH-60Rs to replace its 7 aging Lynx helicopters. In October 2015, the US Navy accepted two mission ready MH-60R helicopters for Denmark. In October 2018, Lockheed Martin was in the process of delivering the ninth and final MH-60R to Denmark. Denmark operates 9 units with 723 Squadron (Eskadrille 723), Royal Danish Air Force (Flyvevåbnet), based at Karup Air Base (Flyvestation Karup).
