With the retirement of the Sea Knight the squadron designation of Helicopter Combat Support Squadron (HC) was also retired from the navy. Operating Sierra squadrons were re-designated Helicopter Sea Combat (HSC).

Unlike all other Navy H-60s, the MH-60S is not based on the original S-70B platform with its forward-mounted twin tail-gear and single starboard sliding cabin door. Instead, the Sierra 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 [1].

MH-60R Seahawk

An MH-60R conducts sonar operations.

The MH-60R is designed to replace the SH-60Bs and SH-60Fs, and be a true multi-mission helicopter. Its sensors include the ASE package, MTS-FLIR, an advanced airborne fleet data link, and a more advanced airborne active sonar. It does not carry the MAD suite. Pilot instrumentation will be based on the MH-60S’s glass cockpit, using several digital monitors instead of the complex array of dials and gauges in Bravo and Foxtrot aircraft. 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 will be redesignated Helicopter Maritime Strike (HSM).[2]

The Fleet Replacement Squadron (FRS), HSM-41, received the R-model (or Romeo) aircraft in December 2005 and has begun training the first set of pilots. In 2007, the MH-60R successfully underwent final testing for incorporation into the fleet. As of August 2008, the first 11 combat-ready examples equipped HSM-71, a squadron assigned to the USS John C. Stennis (CVN-74). According to Lockheed Martin, "secondary missions include search and rescue, vertical replenishment, naval surface fire support, logistics support, personnel transport, medical evacuation and communications and data relay."[3]
