Umm Naasan Naval Air Station

Umm Naasan Naval Air Station (Arabic: محطة امّ النعسان البحرية الجوية maḥaṭṭat umm an-na‘asān al-baḥrīyah al-jawīyah) is the largest operational military base of the Arab Navy. Umm Naasan Naval Air Station is located on the otherwise uninhabited island of Umm Naasan just off the west coast of Bahrain.

The base takes up the great majority of the island, especially the airbase section; the northern entrance with most administrative buildings sits along highway 80, which is connected by bridges to the main island of Bahrain to the east and Khobar, Peninsular Republic to the west. The base sits roughly halfway between the city of Khobar and the Bahraini capital of Manama.

Umm Naasan Naval Air Station is both a regular naval base, with a docking capacity at least 300% and a drydock capacity nearly 200% that of Budapest Naval Station (the navy's headquarters and second-largest base), and a naval air station, home to four runways utilised by Naval Air Corps aircraft, including those too large to land on the Arab Navy's six aircraft carriers.
