List of United States Navy aircraft squadrons

The first operational fleet squadron to receive the MH-60R was [[HSM-71]] in fiscal year 2008. With the transition of the HS squadrons to HSC squadrons without any ASW capability and the disestablishment of the last [[List of inactive United States Navy aircraft squadrons#(VC)(VS) Air Anti-submarine/Sea Control Squadrons|Sea Control (VS) squadrons]], all ship based airborne ASW capabilities now reside in the HSM squadrons.

From 2008 to 2016 all Helicopter Anti-Submarine (Light) (HSL) squadrons transitioned to the [[MH-60R]] and were redesignated Helicopter Maritime Strike (HSM) squadrons and five new HSM squadrons were established. This provided one HSM squadron to each [[carrier air wing]] and non-carrier air wing land-based "expeditionary" squadrons to provide detachments to [[Surface combatant|surface ships]]. An additional expeditionary squadron was established later in 2021. Carrier air wing squadrons are composed of eleven helicopters. They deploy aboard aircraft carriers with their carrier air wing and also provide detachments to other ships of the Carrier Strike Group.{{efn|only five of the eleven helicopters embark aboard the aircraft carrier, the remaining six embark in detachments of two helicopters each in three of the carrier strike group surface combatants (Cruiser and/or Destroyers}} "Expeditionary" squadrons are non-deploying squadrons composed of between ten and fifteen helicopters which provide detachments of two helicopters each to ships which deploy independently, not as part of a carrier strike group.

Carrier air wing squadrons are operationally assigned to their [[carrier air wing]] and administratively to a [[List of United States Navy aircraft wings|type wing]] (Helicopter Maritime Strike Wing Atlantic or Pacific) while expeditionary squadrons and fleet replacement squadrons are assigned only to a type wing which exercises both operational and administrative control over those squadrons. HSM-60 which is the sole USNR helicopter squadron is assigned operationally and administratively to the Navy Reserve's Maritime Support Wing.
