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.

In 2022, the Royal Norwegian Airforce is considering the UH-60 as a replacement for the NHIndustries NH90. On March 14, 2023, the Norwegian Ministry of Defence announced that Norway will procure MH-60R Sea Hawk for the Norwegian Coast Guard. Training is to start immediately in cooperation with the Royal Danish Air Force. The U.S. government decided to reallocate three MH-60Rs originally destined for the U.S. Navy to the Norwegian Coast Guard, with an estimated delivery in the summer of 2025. Norway will procure a total of six MH-60Rs, with the remaining three delivered by 2027. Norway is also considering procuring additional helicopters for the Anti Submarine warfare role for the Royal Norwegian Navy Fridtjof Nansen-class frigate, pending review into how to best satisfy the navy's ASW needs.
