The 1990–1991 Gulf War was the last major United States Air Force combat operation of the 20th Century. The command and control of allied forces deployed to the Middle East initially as part of Operation Desert Shield, later engaging in combat operations during Operation Desert Storm, were assigned to United States Central Command Air Forces (USCENTAF), the USAF component of the Joint United States Central Command. United States Air Force units were initially deployed to Saudi Arabia in August 1990, being assigned directly to CENTAF with a mission to defend the kingdom. In November 1990, the decision was made to enhance the force into an offensive-capable one, and additional units were ordered deployed to CENTAF. As a result, CENTAF set up a table of organization which established provisional Air Divisions to prevent too many units reporting directly to CENTAF headquarters. These were as follows: The 14th Air Division (Provisional) commanded deployed primarily Tactical Air Command and United States Air Forces in Europe units with the mission of destroying enemy air, missile and ground forces, as well as enemy infrastructure targets. To accomplish this mission, the 14th-controlled A-10 Thunderbolt II ground attack aircraft; F-15C Eagle and F-16 Fighting Falcon fighters; F-111 light tactical bombers; EF-111 Raven electronic combat aircraft and the F-117 stealth attack aircraft. The division also provided electronic warfare, reconnaissance, and in-theater attached Strategic Air Command refueling support. The 15th Air Division (Provisional) commanded deployed Tactical Air Command units with a reconnaissance and electronic warfare mission focused on defeating enemy ground base air defenses and increasing the effectiveness of friendly formations. Aircraft deployed included RF-4C Phantom II tactical reconnaissance; F-4G Phantom II anti-radar; EC-130H Compass Call electronic warfare and two prototype E-8A Joint Stars battle management and command and control aircraft. The 1610th Air Division (Provisional) controlled Military Airlift Command C-130E/H Hercules theater airlift, aeromedical evacuation and Air Force Special Operations Command forces. Strategic Air Command deployed strategic electronic warfare and reconnaissance units also attached. The 17th Air Division (Provisional) commanded primarily provisional air refueling wings created from active-duty KC-135/KC-10 units of the Strategic Air Command's Fifteenth Air Force and SAC Air National Guard KC-135 units deployed within the CENTAF AOR. The SAC 7th Air Division commanded deployed Air Refueling and B-52 Stratofortress Bombardment Wings located outside of the CENTAF AOR. The 7440th Composite Wing was a United States Air Forces in Europe (USAFE) Provisional Wing under Joint Task
