Former Atlas E Missile Base on 24.5 private, fenced acres in Eastern Washington, offering approximately 19,000 SF of specialty improvements, including 16,000+ SF of hardened underground space constructed with steel-reinforced, approximately 18-inch-thick, 20,000-psi concrete. The facility features an operational 47-ton blast door, vehicle-accessible underground space suitable for trucks and large equipment, elevator access to subterranean living and flexible-use areas, and an approximately 1,600-foot on-site airstrip footprint. Above ground are two metal buildings, living quarters, multiple large workshops, and garage and equipment-storage areas. The property is move-in ready, with a functioning 375+ foot well, a secondary inactive well, a septic system, dual 200-amp electrical services, and Starlink internet. Located in a designated Opportunity Zone with access to I-90, Spokane, Spokane International Airport, and the broader Inland Northwest, this is a rare combination of privacy, acreage, infrastructure, and virtually impossible-to-replicate hardened construction. Potential adaptive uses include specialty or secure storage, R&D, collector and equipment storage, workshop or manufacturing concepts, production and film use, experiential hospitality, training facilities, corporate retreats, and other specialty commercial applications, subject to zoning and governmental approvals. This is more than a property with buildings—it is an existing hardened infrastructure asset whose reinforced underground construction, massive access systems, and historic engineering would be extraordinarily difficult and potentially cost-prohibitive to reproduce today. Private showings by appointment; proof of funds required. Contact 239-989-4545, email cspary@icloud.com, or visit WashingtonMissileBase.com for additional information.
