US nuclear force still uses floppy disks. BBC News Services. 26 May 2016.
A government report shows that the US nuclear weapons forces ( intercontinental ballistic missiles, nuclear bombers and tanker support aircraft) still use a 1970s-era computer system and 8-inch floppy disks. The GAO said there were "legacy systems" which need to be replaced. Legacy systems cost about $61bn a year to maintain. "This system remains in use because, in short, it still works." "However, to address obsolescence concerns, the floppy drives are scheduled to be replaced with secure digital devices by the end of 2017." According to the report, the US treasury systems, still use a system written in "assembly language code".
