The squadron flies the Boeing E-6B Mercury airborne command post and communications relay aircraft.

It is part of the Navy's TACAMO community, whose mission is to enable the President of the United States and the Secretary of Defense to directly communicate with U.S. submarines, bombers, and missile silos during a nuclear war.

It deploys aircraft to fly operational patrols out of Travis Air Force Base, California.

The squadron transitioned from the EC-130Q to the Boeing E-6A Mercury in 1989-90, and relocated to Tinker Air Force Base in 1992.
