Morón Air Base (Base Aérea de Morón) and the US-Spain Agreement on Defense Cooperation

Morón de la Frontera hosts Morón Air Base, used by US Air Force tanker/space-operations detachments and, since 2015, a rotational US Marine Corps crisis-response force, under the bilateral Convenio de Cooperación para la Defensa entre España y Estados Unidos (signed 1 December 1988, amended by protocols in 2002, 2012/2013 and 2015, and renewed — the agreement renews automatically each year unless either party objects).

Why it matters

Relevant background for anyone moving to Morón who may interact with the US base community, work in related services, or simply want to understand why there is a visible US military presence in this specific town; it is NOT personal immigration/legal advice.

When

Curiosity about the US military presence in Morón de la Frontera, or being a US service member/dependent posted to Morón Air Base (in which case your in-processing office, not this item, governs your specific entitlements).
