13th School Group

The 13th School Group is an inactive United States Air Force unit. It was last assigned to the 24th School Wing, and was demobilized on 30 April 1931 at March Field, California.

The unit was an early United States Army Air Corps flying training group, and the first major unit assigned to March Field after its re-opening in 1927.

History
During World War I, March Field was a major primary pilot training base for the Air Service, with its graduates being sent to advanced training schools before being deployed to the American Expeditionary Force in France. The school was closed after the armistice in February 1919.

In July 1919, Congress authorized resumption of enlistment of flying cadets on a limited basis, and the school at March Field was re-opened which offered a combined ground school and primary flight training using surplus Curtiss JN-4 Jennies. A shortage of money and failure of the training program to become as large as planned, prompted the closing of the primary school at March Field in 1921, and March became a storage depot. In 1922 it was decided to centralize all flying training in San Antonio, Texas.

The decision by the Coolidge Administration in 1926 to expand the Air Corps found the facilities in San Antonio insufficient to accommodate the expanded number of cadets entering primary training. As a result, March Field was re-opened as a primary pilot training school in July 1927, and the  13th School Group was designated to perform duties as the headquarters for the new Air Corps Primary Flying School. Flight training was conducted in Consolidated PT-1 and PT-3s, which had taken over from the Curtiss Jennies. There were three school squadrons assigned, along with support squadrons.

Even before the school at March opened, it was known it was a temporary unit, as plans were ongoing to expand the facilities in San Antonio. With the opening of Randolph Field in 1931, the primary pilot training at March ended in April 1931 and March Field became the home of the new 1st Bombardment Wing.
