Four Brandenburg-class F123 warships employ floppies for data-acquisition systems.
The German Navy is working on modernizing its Brandenburg-class F123 frigates, which means ending their reliance on 8-inch floppy disks.The F123 frigates use floppy disks for their onboard data acquisition (DAQ) systems, as noted by Tom’s Hardware on Thursday. Augen geradeaus!, a German defense and security policy blog by journalist Thomas Wiegold, notes that DAQs are important for controlling frigates, including power generation, "because the operating parameters have to be recorded," per a Google translation. The ships themselves specialize in anti-submarine warfare and air defense.
