According to a watch dog report released Wednesday, America’s nuclear force still uses floppy disks designed in the 1970s to coordinate some of its functions.

The report by the Government Accountability Office points out a number of worrying outdated “legacy systems” still in use across the US government that desperately need of upgrade.

A Pentagon command and control system that “coordinated 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, a type of computer debuted in 1976, and uses 8-inch floppy disks.

The military did not make an immediate respond for request for a comment but according to the GAO report, the Pentagon is planning on fully replacing the system by the end of 2020.

GAO also added that the federal government is spending a lot more on “operations and maintenance” of its computer system rather than on its “development, modernization and enhancement.”

The report also found that the Department of the Treasury uses “assembly language code,” which was initially designed in the 1950s.


The Office of Management and Budget has started an initiative to replace the legacy system, “but until this policy is finalized and fully executed, the government runs the risk of maintaining systems that have outlived their effectiveness,” the reporter states.
