King Abdulaziz Air Base (IATA: DHA, ICAO: OEDR) , formerly Dhahran International Airport and Dhahran Airfield is a Royal Saudi Air Force Air Base located in Dhahran in the Eastern Province of Saudi Arabia.
 It's the first airport ever built in Saudi Arabian soil.
 It was operated by the United States Air Force (USAF) from 1945 until 1962.
 After use by the USAF, Dhahran Airfield became Dhahran International Airport, as well as the co-located King Abdulaziz Air Base of the Royal Saudi Air Force (RSAF).
 The military relationship that exists today between the United States and Saudi Arabia was highly influenced by the origin and development of this airfield.
 The base is close to other major cities in the area including Al-Thuqbah (5 km to the east), Khobar (5 km to the southeast), and Dammam (25 km to the northwest).
Beginning during Operation Desert Shield in August 1990, while preparing for the Gulf War, the United States sent a large troop contingent to Saudi Arabia.

 The United Kingdom and France also maintained a small contingent of Royal Air Force and French Air Force training personnel.
