Northwest Iowa Regional was deactivated during 1944 with the drawdown of AAFTC's pilot training program.

The property was declared surplus, turned over to the Army Corps of Engineers on 30 September 1945 and was eventually discharged to the War Assets Administration (WAA) to become a civil airport, eventually renamed Spencer Municipal.
