US nuclear force still using 1970s floppy disks warns watchdog

America’s nuclear force still uses floppy disks designed in the 1970s to coordinate some of its functions, according to a watchdog report released. The report by the Government Accountability Office points to a number of worryingly outdated “legacy systems” still in use across the US government that are in desperate need of upgrading. A Pentagon command and control system that “coordinates the operational functions of the United States’ nuclear forces, such as intercontinental ballistic missiles, nuclear bombers, and tanker support aircrafts,” runs on an IBM Series/1 computer and uses 8-inch floppy disks, the report says.
