How COMINT Supported U.S. Air Controllers During the Korean War

As an air force captain in the Korean War and a lieutenant colonel in the Vietnam War, Delmar Lang developed innovative collection that provided vital support to those flying missions over enemy territory.

Lang grew up in Toledo and Cleveland. In the late Depression years, he had no change to attend college. After the Japanese attack on Hawaii, realizing he likely would be drafted soon anyway, Lang enlisted in the army in March 1942. He found that AFSS headquarters at former Ehwa Women’s University, in the suburb s of Seoul, had a robust collection program against Morse communications.
