After V-E Day, the squadron moved to England and mapped large areas of Europe until October 1945, when it began to stand down for inactivation.

The squadron specializes in training United States service members and NATO partners to support transient fourth and fifth generation electronic warfare aircraft.

It deployed to Mexico to perform photographic mapping over Central and South America with long range Boeing F-9 Flying Fortress and Consolidated F-7 Liberator aircraft.

Reassigned to the 311th Reconnaissance Wing, the squadron moved overseas, being attached to the Royal Air Force.

It was later assigned to Egypt, mapping the Middle East with long-range aircraft including some Consolidated OA-10 Catalinas, photographing airfields, coastal defenses and ports.

Reassigned to England in April 1945, the squadron took bomb-damage assessment photographs of airfields, marshalling yards, bridges and other targets.

[6] President Truman’s reduced 1949 defense budget required reductions in the number of units in the Air Force,[7] and the 19th was inactivated[2] and not replaced as reserve flying operations at Newark ceased.

It became the primary night photographic reconnaissance squadron of the USAFE, being assigned to bases in West Germany, England and France.

The squadron was inactivated in 1970 at Kadena Air Base, Okinawa as part of the draw-down of USAF forces in Southeast Asia.

The unit operates systems supporting Polygone, a multinational electronic warfare range on the German-French border.
