Exterior of Oscar Zero
Located on State Highway 45, this non-descript compound is the site of the former Oscar-Zero Missile Alert Facility in Cooperstown, ND.
This security fence is the only indication that Oscar-Zero was a top secret, and secure military installation.
In 1964, a 60-foot trench the size of a football field was excavated to build the concrete bunkers that would become Oscar-Zero.
Before construction of Oscar-Zero was complete, an elevator shaft was added, then two structures were built at ground level to conceal the concrete-hardened bunkers.
Blast door under construction
This massive 14-ton blast door, was one of two, and so large that it was placed in the ground during construction of the concrete-hardened bunkers in 1964.
LCEB blast door
The 14-ton blast door to the Launch Control Equipment Building, which provided the life support for the two USAF Missileers that worked 24-hour shifts 50 feet below the surface.
Emergency exit shaft
An emergency evacuation staircase shaft was the only way out of the concrete-bunkers if the elevator was inoperable.
LCC blast door
A 7-ton blast door provided necessary protection in case of nuclear attack. Only able to be opened from the inside, the two Missileers were locked inside 24-hours per shift.
