Formed in Australia in early 1942 by a combination of Fifth Air Force personnel and Boeing B-17 Flying Fortress aircraft that escaped from the Philippines and replacement aircraft that reached Australia from Hawaii and via the South Atlantic air ferry route from Florida, and arriving in Western Australia. As the 40th Reconnaissance Squadron, the squadron evacuated General Douglas MacArthur and President Manuel Quezon from Del Monte Field in the Philippine Islands in March 1942. Redesignated as 435th Bombardment Squadron and engaged in strategic bombardment and reconnaissance of enemy targets in New Guinea; Coral Sea and Solomon Islands from Northern Queensland. The 435th Squadron operated primarily as a reconnaissance squadron in the Southwest Pacific area. Two thirds of more than 540 combat missions in the Australian Theater were reconnaissance missions. All of the 168 missions out of Hawaii and the Fiji Islands were patrols. Although a portion of the 19th Bombardment Group in Australia, technically speaking, this squadron operated independently of the group and under the direct supervision of the 5th Bomber Command. Photographs and information went directly to 5th Bomber Command. Withdrawn from combat in November 1942 when the B-17C/E models in Australia were replaced by long-range Consolidated B-24 Liberators.
The squadron was again activated at Dalhart Army Air Field, Texas on 7 July 1944, but this time was assigned to the 333d Bombardment Group. The 333d Group was a former heavy bomber training unit that had been inactivated in the spring of 1944 in a general Army Air Forces reorganization of its training and support units. It was reactivated in July as a Boeing B-29 Superfortress group. The squadron trained with Superfortresses until June 1945, when it departed for the Pacific to become an element of Eighth Air Force, which was organizing on Okinawa as a second very heavy bomber air force in the Pacific. However, the squadron did not arrive at its combat station, Kadena Airfield, until it was too late to participate in combat. The squadron flew show-of-force missions and its aircraft helped evacuate prisoners of war from Japan to airfields in the Philippines. The unit was inactivated on 28 May 1946.
