Prince Sultan Air Base — Al Kharj, Saudi Arabia

Prince Sultan Air Base sits near Al Kharj, south of Riyadh, in Saudi Arabia's central Riyadh Region, its two runways positioned at 1,651 feet above sea level. As a military air base rather than a civilian airport, the field handles a very different type of traffic than most facilities of similar size. Al Kharj sits amid irrigated farmland in an otherwise arid stretch of Saudi Arabia's central plateau, south of the capital. Civilian access here stays far more limited than at commercial Saudi airports like Riyadh's King Khalid International, reflecting the base's primarily defense-related role.
