[2] The UH-60J is a search and rescue version for the Japan Air Self-Defense Force (JASDF) and JMSDF.

It is similar to LAMPS Mk.III in that the helicopter is equipped with a computer and connected to the mothership's combat direction system via a datalink, but it also has a dipping sonar as well as SH-60F.

Based on a concept of the JMSDF, HQS-103 Dipping Sonar, HPS-104 active electronically scanned array Search Radar, and HLR-108 ESM System equipment of the avionics of SH-60B be different.

[4] The engine is the GE/IHI T700-IHI-701C turboshaft, which Ishikawajima-Harima Heavy Industries produced under license from General Electric.

[11] In December 2022, the Japanese government decided to reduce the number of SH-60Ks deployed for maritime patrols and replace some SH-60Ks with Sea Guardian unmanned aerial vehicles.

[18][19] The first aircraft was built by Sikorsky, with the company designation S-70A-12, and two more were assembled by Mitsubishi Heavy Industries.

[21][22] The Japan Marine Self-Defense Force also chose Search and rescue, and utility helicopters to replace the S-61A in 1989.

[26] These UH-60Js completed training with the United States Air Force and widened their activity in SAR mission.

[3] It features improved avionics, including FLIR, Color weather radar, GPS receiver, a Night Vision Goggle compatible cockpit and wire cutter.

Due to budgetary constraints it was decided to replace the rotary wing fleet with a high-low combination of UH-60JA and UH-1J (an updated UH-1H) with the UH-60JA being the high and the UH-1J the low.

[30] By 2004, the budgetary constraints have driven the JGSDF to seriously consider eliminating either the UH-60JA or the UH-1J from the fleet, and purchasing just one type of airframe for the utility mission.

[44][45] A private salvage company started work from 2 November and located part of the fuselage.

[46][47] In November, parts of the aircraft were recovered including the Flight Data Recorder (black box) from a location approximately 31 kilometers south of Hamamatsu Air Base.

[50][51] On 20 April 2024, two SH-60Ks carrying four crew members each crashed near Torishima Island during a nighttime anti-submarine warfare training operation.

The Japanese Maritime Self-Defense Force sent 12 vessels and seven aircraft to aid in search operations.

Ambassador to Japan Rahm Emanuel offered the United States's support with the search and rescue operation.
