Prince Sultan Air Base () is a military air base located in Al Kharj, Saudi Arabia. There was formerly a large United States presence there during Operations Southern Watch, Enduring Freedom and Iraqi Freedom. The U.S. presence was predominantly that of multiple U.S. Air Force (USAF) flying units, augmented by a U.S. Navy (USN) or U.S. Marine Corps (USMC) EA-6B Prowler squadron, a Royal Air Force (RAF) fighter squadron with Tornado F.3s and a French Air Force (ALA) fighter squadron with Mirage 2000s plus a C-135RF air refueling aircraft. Following the attack on U.S. Air Force facilities at Khobar Towers in Dharan in 1996, all USAF activities at that location were relocated to PSAB.
