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 United States Air Force (USAF) flying units, augmented by a United States Navy (USN) or United States Marine Corps (USMC) Northrop Grumman EA-6B Prowler squadron, a Royal Air Force (RAF) fighter squadron with Panavia Tornado F.3s and a French Air Force fighter squadron with Dassault Mirage 2000s, Mirage F1 CR plus a Boeing C-135RF Stratotanker air refueling aircraft. Following the attack on USAF facilities at Khobar Towers in Dharan in 1996, all USAF activities at that location were relocated to PSAB.
