91st CES (SAC)

The 91st Civil Engineering Squadron (CES) was an essential support unit under the Strategic Air Command (SAC), stationed at Minot Air Force Base, North Dakota. Tasked with maintaining and constructing facilities, the 91st CES ensured the operational readiness of missile silos and support structures for the 91st Strategic Missile Wing during the Cold War. The squadron played a critical role in base infrastructure, emergency response, and environmental management, directly supporting the nation's nuclear deterrence mission. Over the years, the 91st CES adapted to evolving technologies and mission requirements, remaining a vital component of the U.S. Air Force's strategic capabilities.
