Advances in sensor and avionic technology lead to the LAMPS Mk II suite being developed by the Naval Air Development Center. The Navy then conducted a competition in 1974 to develop the Lamps MK III concept which would integrate both the aircraft and shipboard systems. The Navy selected IBM Federal Systems to be the Prime systems integrator for the Lamps MK III concept. Since the SH-2 was not large enough to carry the Navy's required equipment a new airframe was required. In the mid-1970s, the Army evaluated the Sikorsky YUH-60 and

SH-60B Seahawk

IBM was the prime systems integrator for the Lamps MK III with Sikorsky as the airframe manufacturer. The SH-60B maintained 83% commonality with the UH-60A. The main changes were corrosion protection, more powerful T700 engines, single-stage oleo main landing gear, removal of the left side door, adding two weapon pylons, and shifting the tail landing gear forward to reduce the footprint for shipboard landing. Other changes included larger fuel cells, an electric blade folding system, folding horizontal stabilators for storage, and adding a 25-tube pneumatic

The SH-60F was operated by the U.S Navy's Helicopter Antisubmarine (HS) squadrons until they were redesignated Helicopter Sea Combat (HSC) squadrons and transitioned to the MH-60S. The last HS squadron completed its transition in 2016.

HH-60H

The HH-60H was developed in conjunction with the US Coast Guard's HH-60J, beginning in September 1986 with a contract for the first five helicopters with Sikorsky as the prime contractor. The variant's first flight occurred on 17 August 1988. Deliveries of the HH-60H began in 1989. The variant earned initial operating capability in April 1990 and was deployed to Desert Storm with HCS-4 and HCS-5 in 1991. The HH-60H's official DoD and Sikorsky name is ''Seahawk'', though it has been called "Rescue Hawk".

The HH-60H can carry up to four AGM-114 Hellfire missiles on an extended wing using the M299 launcher and a variety of mountable guns including M60D, M240, GAU-16 and GAU-17/A machine guns. The HH-60H's standard crew is pilot, copilot, an enlisted crew chief, and two door gunners or one rescue swimmer. Originally operated by HCS-5 and HCS-4 (later HSC-84), these two special USNR squadrons were established with the primary mission of Naval Special Warfare and Combat Search and Rescue (CSAR). Due to SOCOM budget issues the squadrons were deactivated in 2006 and 2016 respectively. The HH-60H was also operated by Helicopter Antisubmarine (HS) squadrons with a standard dispersal of six F-models and two or three H-models before the transition of HS squadrons to HSC squadrons equipped with the MH-60S, the last of which completed its transition in 2016.

MH-60R

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.

Unlike all other Navy H-60s, the MH-60S is not based on the original S-70B/SH-60B platform with its forward-mounted twin tail-gear and single starboard sliding cabin door. Instead, the S-model is a hybrid, featuring the main fuselage of the S-70A/UH-60, with large sliding doors on both sides of the cabin and a single aft-mounted tail wheel; and the engines, drivetrain and rotors of the S-70B/SH-60.

Operational history

U.S. Navy

The Navy received the first production SH-60B in February 1983 and assigned it to squadron HSL-41.Donald 2004, pp. 156–157. The helicopter entered service in 1984, and began its first deployment in 1985. The SH-60F entered operational service on 22 June 1989 with Helicopter Antisubmarine Squadron 10 (HS-10) at NAS North Island. SH-60F squadrons planned to shift from the SH-60F to the MH-60S from 2005 to 2011 and were to be redesignated Helicopter Sea Combat (HSC). As one of the two squadrons in the US Navy dedicated to Naval Special Warfare support and combat search and rescue, the HCS-5 Firehawks squadron deployed to Iraq for Operation Iraqi Freedom in March 2003. The squadron completed 900 combat air missions and over 1,700 combat flight hours. The majority of their flights in the Iraqi theater supported special operations ground forces missions.
