Loring Air Force Base Arch Hangar, Military aircraft hangar in Limestone, Maine, United States.
The Arch Hangar spans 340 feet wide and 314 feet long, making it one of the largest monolithic arch roof structures in the United States.
Built between 1947 and 1949, the Arch Hangar served as a crucial facility for Strategic Air Command operations during the Cold War period.
The structure represents a significant example of post-World War II military architecture and engineering achievements in the United States defense infrastructure.
The hangar requires substantial restoration work to address structural issues, including roof repairs and reinforcement of its concrete sections.
The construction process involved an uninterrupted 26-hour concrete pour to create twelve individual sections forming the distinctive arch shape.
