(...) at the Stanley R Mickelsen SAFEGUARD Complex. This anti-ballistic missile defense site - the only one to be built in the US -- was designed to detect and intercept attacking nuclear warheads from Soviet missiles coming over the North Pole. Nuclear-tipped Sprint and Spartan anti-ballistic missiles were deployed at the site to shoot down the incoming Soviet missiles. The facility, built in the early to mid 1970s at a cost of US$5.7 billion, near Langdon, North Dakota, was fully operational for only a day in October 1975 before Congress voted to shut it down. At the time it had one of the most advanced radar systems, and boasted one of the most powerful computers, in the world. Because of its effect as a deterrent to the Soviets, it is seen as having been a bargaining chip for the US in the SALT treaties. North Dakota. USA. November, 2017. © Sim Chi Yin | Magnum Photos
