El Centro NAF Airport (Vraciu Field) — El Centro, United States

NJK is El Centro Naval Air Facility, home to Vraciu Field, in the Imperial Valley of Southern California near the Mexican border. Best known as the winter home of the US Navy's Blue Angels flight demonstration squadron, NJK offers ideal year-round flying weather that supports intensive training seasons before the team's public airshow schedule begins each spring. The base also supports other naval aviation training detachments taking advantage of the region's clear skies and open desert airspace. Established during World War II, El Centro has long served as a training and testing outpost distinct from more congested coastal naval air stations. NJK remains closed to general civilian aviation, operating exclusively for military purposes.
