For 14 years, they were the last resort for protecting the Twin Cities in case of a Soviet air attack.
With 15 minutes' warning, Nike Hercules missiles could be raised from bunkers, moved to launchpads and aimed to shoot down enemy bombers before they reached the metro area.
One of the few remaining deactivated missiles in the country still is standing in the southwest metro city of St. Bonifacius. It has received much greater appreciation recently with the addition of interpretive panels.
"People questioned why we had it, and they didn't know what it meant," said Fred Keller, president of the St. Bonifacius area community development group.
Keller, 72, served in the Navy in Guantanamo Bay shortly before the Cuban missile crisis in 1962, so he's well aware of what things were like when the St. Bonifacius missile base was built in 1958.
It's history familiar to others who grew up during the early Cold War years in the 1950s and 1960s, when Soviet achievements in developing nuclear weapons and launching the Sputnik satellite had the United States worried about defending its major cities, military bases and industrial centers. Schools practiced "duck and cover" drills in case of an attack, and some families built bomb shelters.
The Army built defensive missile bases at dozens of locations, including four that ringed the Twin Cities near St. Bonifacius, Farmington, Bethel and Roberts, Wis.
Defense only
The St. Bonifacius site, on farmland about 25 miles from Minneapolis, was chosen because it's one of the highest points in Hennepin County, Keller said. It contained missiles stored horizontally underground, three large radar units above ground and an administrative building.
