The 81st was the first Sabre Jet unit to be based in Europe, and the first to form an integral part of the peacetime air defense of Great Britain. In this role, the wing came under the operational control of the Royal Air Force Fighter Command No. 11 Group during the actual defense of the United Kingdom, and for combined operational training. Under USAFE, the 81st came under the control of Third Air Force which coordinated its activities with the RAF. Although the pilots had a relatively short time to acquaint themselves with RAF techniques and procedures and the methods of fighter control, the unit made and excellent showing.
