The Dakota Complex, also known as the Dakota Test Site, was the largest US Government research facility in the central United States. Mostly underground, the area had the capacity to test both NASA and military rockets, along with an apparently wide range of other devices. Its lead scientist was Dr. Elijah Cooper. It was the site of the alleged "Doomsday Weapon", which was said to have the capability to end all life on Earth. (Doomsday Is Tomorrow, Doomsday Is Tomorrow (Part II))
