Equipped with F-51D Mustangs with an air defense mission for Southeastern Pennsylvania and Philadelphia.

With the end of the line for the Mustang in USAF service, the United States Air Force, in an effort to upgrade to an all jet fighter force, required Air National Guard Air Defense Command units to upgrade to jet-powered aircraft.
