The **Chilean Air Force** (Fuerza Aérea de Chile, FACh) is the aerial warfare branch of Chile's military, tasked with defending national airspace, supporting ground operations, and contributing to strategic national defense objectives. Established in the early 20th century, it is the fourth oldest independent air force globally, preceding the U.S. Air Force by 17 years, reflecting Chile’s early commitment to aerial defense and technological advancement[2]. FACh operates under three main commands: Combat, Logistics, and Personnel. Its operational units are organized into five air brigades located strategically across Chile, including bases in Iquique, Santiago, Puerto Montt, Punta Arenas, and Antofagasta. Additionally, it maintains an airbase on King George Island in Antarctica, underscoring its strategic reach in remote regions[1][2][4]. The force fields approximately 277 aircraft as of 2025, comprising a diverse fleet including 59 combat aircraft, 87 helicopters, 65 training planes, 49 transports, and 17 special mission aircraft. Notably, Chile’s combat aircraft inventory includes advanced U.S.-origin F-16 fighters—both Block 50 and reconditioned Block 15 models—placing it among Latin America's most capable air forces[2][4]. Historically, the Chilean Air Force has continuously evolved its capabilities, serving as a foundation for Chile's broader aerospace system. Its roles span peacetime airspace control, wartime combat, intelligence, surveillance, reconnaissance, and support of allied forces[2]. FACh's commitment to interoperability is highlighted by joint exercises with U.S. Special Operations Command, showcasing advanced tactics such as forward arming and refueling points, airborne insertions, and integrated intelligence sharing using platforms like the U-28A Draco[6]. Current notable aspects include its integration of advanced aerospace technology, strategic positioning with multiple airbases, including the Antarctic, and active partnerships with international force
