The system, called Strategic Automated Command and Control System, or SACCS, “is still in use today but no longer uses floppy disks,” David Faggard, a spokesman for the Air Force Global Strike Command, which manages the Air Force portion of the arsenal, said in an email. “Air Force Global Strike Command is committed to modernizing for the future.”The update is part of a broader overhaul of the United States’ atomic weapons that began under President Barack Obama and has continued under President Trump. The move away from floppy disks was completed in June but was not widely reported at the time. “The Air Force completed a replacement of the aging SACCS floppy drives with a highly secure solid-state digital storage solution in June,” Justin Oakes, a spokesman for the Eighth Air Force , said in an email. “This replacement effort exponentially increased message storage capacity and operator response times for critical nuclear command and control message receipt and processing.”
