Wow.

(CNN)Want to launch a nuclear missile? You’ll need a floppy disk.

That’s according to a new report by the U.S. Government Accountability Office (GAO), which found that the Pentagon was still using 1970s-era computing systems that require “eight-inch floppy disks.”

[…]

The report says the Pentagon is planning to replace its floppy systems — which currently coordinate intercontinental ballistic missiles (ICBMs), nuclear bombers and tanker support aircraft — by the end of 2017.

To be fair, many of those missile systems were also created in the same time period, but still… I suppose there is something of an advantage that hackers will have a hard time hacking a floppy without physical access to it.
