America’s nuclear forces has finally ended the use of the floppy disk for coordinating the country’s nuclear forces. The USA’s Strategic Automated Command and Control System (SACCS) have transitioned to a highly secure solid state digital storage solution. The old machines had to be repaired and soldered by hand because they couldn’t be easily replaced. The old antique of a system had the advantage by running entirely offline which cuts off a key attack vector. The disadvantage arises when the system would break and you need to swap out components, the maintainers would have to use soldering irons.
The surprising fact is that you can still find floppy discs in old industrial machines and medical devices. If a machine is designed to be used for many years, it is not cost effective to replace it immediately as the newer storage medium becomes available. Physical media is becoming a rare sight for consumers but everywhere else it will probably stick around for decades.
