[2] Helicopter Anti-Submarine Squadron 11 was established on 27 June 1957 at Naval Air Station (NAS) Quonset Point, Rhode Island.

The HS-11 Sub Seekers were assigned to Carrier Anti-Submarine Air Group 52 (CVSG-52) with tail code AS and deployed on board USS Wasp (CVS-18).

In September 1962 the squadron's HSS-1N helicopters were re-designated the SH-34J Seabat in compliance with the 1962 United States Tri-Service aircraft designation system.

In December 1969, HS-11 became the first ASW helicopter squadron to deploy as part of a modern carrier air wing with CVW-17 on board USS Forrestal (CVA-59).

In 1976, the squadron was awarded the Navy Unit Commendation for saving countless lives after ship collisions at sea while attached to USS John F. Kennedy (CV-67).

On 1 June 2016, HS-11 completed transition to the MH-60S Seahawk, was redesignated HSC-11,[2] and moved from NAS Jacksonville to Naval Station Norfolk, Virginia.
