Thule Site J, Military radar station in northwestern Greenland.
The radar installation contains detection reflectors and extensive refrigeration systems to maintain concrete structures in the Arctic permafrost conditions.
Construction of Site J began in May 1958 as part of the Ballistic Missile Early Warning System during Cold War military expansion.
The facility reflects the intersection of military technology and Arctic environmental adaptations through its specialized construction methods and operational procedures.
Access to the facility requires air transportation, with personnel operating under extreme weather conditions and limited supply routes.
The northernmost radar station in the Solid State Phased Array Radar System monitors missile threats and tracks spacecraft above the Arctic Circle.
