Twin geodesic-domed structures at four Minimally Attended Radar (MAR) sites received a Department of Defense engineering and industrial design award in 1986. Alaska District awarded the $36.3 million project in 1982 to build support facilities at Indian Mountain, Tatalina, Sparrevohn and Cape Romanzof. The project designed permanent, self-contained shelter for a new generation of radar equipment, vehicles, supplies and living space for personnel. Technological advances had automated radar equipment and reduced crews at the remote stations from almost 100 to about 15 technicians at each site.
