Sparrevohn LRRS Airport — Sparrevohn, United States

Sparrevohn Long Range Radar Site Airport (SVW) is an isolated airstrip in southwestern Alaska built to support a Cold War-era Air Force radar installation designed to detect incoming aircraft over remote Arctic approaches. Located far from any town, the facility exists almost entirely to service the radar station's small staff and maintenance crews, with supply flights delivering fuel, equipment, and personnel. SVW's gravel runway sits on rugged mountainous terrain, making operations weather-dependent and logistically demanding. As part of a network of similar Alaskan radar sites, Sparrevohn reflects the strategic military infrastructure built during heightened Cold War tensions. Even today, the airstrip remains essential for maintaining this remote, automated defense outpost.
