The idea of forming an Air Force Station at Sarsawa was conceived during World War II, 1942-1945. Initially an Air-field was developed near Saharanpur city, west of Yamuna canal and by the time Sarsawa Air field came into being, 2nd world war was over and active use of the airfield was abandoned and handed over to civil aviation for VIP movements. It was the Indo-China war in 1962 which once again created the requirement of this air field for active use by defence forces. The repair work started during Sep-Oct 1962 for using this air field as diversionary air field for Ambala and Palam. 11 Care and Maintenance Units came into being in 1964 at Sarsawa. After Indo-Pak conflict 1965, the second phase of expansion was taken up and on 1 Jan 1970 30 Wing came into existence. On 01 Jan 1970, 116 HU was raised here which moved to 32 Wing on 15 Aug 88. 41 LAS was attached to this wing on 23 Feb 1983 but moved out Palam on change over to Dornier on 3 Feb 2005. In addition 104 HU was formed here on 15 May 1976 and moved out to 35 Wing on 8 April 1990.
