On 1 March 1951 the 110th was federalized and brought to active-duty due to the Korean War. It was initially assigned to Strategic Air Command (SAC) and transferred to Bergstrom AFB, Texas. The 131st Fighter-Bomber Group was composed of the 110th Fighter Squadron, the 192d Fighter Squadron (Nevada ANG), the 178th Fighter Squadron (North Dakota ANG), and the 170th Fighter Squadron (Illinois ANG). At Berstrom, its mission was a filler replacement for the 27th Fighter-Escort Group which was deployed to Japan as part of SAC's commitment to the Korean War.
