The North Star Missile Silo, also known as Atlas F Site 550‑4, sits on 18.2 acres near Carlton, Kansas, and contains a 182‑foot‑deep shaft 52 feet across, reinforced with six‑foot‑thick concrete and steel blast doors that once guarded an intercontinental ballistic missile.
Inside the underground complex, a 40‑foot tunnel connects the launch‑control centre to the shaft, which a former owner converted into 2,500 sq ft of finished living space—open‑plan living room, two kitchens, two bedrooms, and two bathrooms—though the renovation was incomplete when the current owners took possession.
The facility became operational in 1962 as part of the U.S. Atlas F ICBM programme and was deactivated on March 25, 1965, after the 550th Strategic Missile Squadron was discontinued; the structure has since been preserved as a relic of the Cold War arms race.
Real Broker agent Ali Schneider says the property remains available for viewings and could serve as an off‑grid conference or wedding venue, and she hints that the owners are open to converting the silo into condominiums if a developer steps forward.
Local farmer John Hines, who passed through the gated driveway last week, said the sight of the towering steel doors “reminds him of the days when every corner of Kansas was a frontline in the global standoff.”
