During the Korean War, GAAF continued in the role as a training and division support field. On the field could be seen L-19 Bird Dog and other observation planes. The L-19 proved to be easy to fly and reliable, with more than 3,000 produced. Pilots trained in L-19s for Forward Air Controller (FAC) roles—directing artillery fire and infantry movement. The 2d Infantry Division began testing helicopters in early 1949 and had nine here. On November 22, 1950, the 2d Aviation Company introduced helicopters, H-13 Sioux's, into the Korean War. Attached to the 8055th Mobile Army Surgical Hospital (MASH), the helicopters transported wounded.
