After the end of World War II the squadron remained in the Far East, serving in the occupation forces in Japan.

It was still in Japan as the 548th Reconnaissance Technical Squadron, when the Korean War began in June 1950.

As the Vietnam War increased the need for photographic interpretation, it expanded to become a group two years later.

The mission of the 548 ISRG is to operate and maintain a $1B AN/GSQ-272 "Sentinel" weapon system (also known as Distributed Ground Station or DGS), and provide combatant commanders with processing, exploitation, and dissemination (PED) of actionable intelligence data collected by U-2, MQ-1, MQ-9 and RQ-4 aircraft and other platforms as required.
