San Julián Air Base — Sandino, Cuba

San Julián Air Base, coded SNJ, is a Cuban military airfield located in the Pinar del Río Province in western Cuba. As a defense installation rather than a civilian airport, SNJ has historically supported the Cuban Revolutionary Air and Air Defense Force, playing a role during periods of heightened Cold War tension in the Caribbean region. The base's strategic location near the western tip of Cuba has drawn periodic international attention regarding regional military posture and airspace activity. Unlike commercial airports, San Julián Air Base does not handle scheduled passenger traffic, and access is restricted to military and government operations, consistent with its designation as core defense infrastructure within Cuba's national security apparatus.
