The German Navy is taking steps to modernize its Brandenburg-class F123 frigates by moving away from their current reliance on 8-inch floppy disks. These floppy disks are currently being used for data acquisition systems onboard the warships, which are crucial for controlling functions such as power generation for the frigates. The F123 frigates are specialized in anti-submarine warfare and air defense.
Recently, a tender for service was published by Germany’s Federal Office of Bundeswehr Equipment, Information Technology, and In-Service Support (BAAINBw) to upgrade the data acquisition systems on the four F123 frigates. These frigates were commissioned between October 1994 and December 1996. Despite the availability of modern alternatives, the continued use of 8-inch floppy disks is due to the perceived reliability of these established systems.
Instead of completely overhauling the data acquisition systems, the German government plans to develop and integrate an onboard emulation system to replace the floppy disks. This approach differs from the US Air Force, which replaced the 8-inch floppies in its intercontinental ballistic missile command, control, and communications network with SSDs in 2019.
Saab has been contracted by the BAAINBw for the updates on the F123 frigates. The Swedish company will deliver and integrate new naval radars and fire control directors for the frigates, along with a new combat management system. The contract is valued at approximately $436,748,840. The replacement of the floppy disks is expected to begin on October 1 and be completed by July 31, 2025, with the F123 frigates expected to remain in service until the arrival of the F126s between 2028 and 2031.
While the specific details of how Saab will replace the floppy disks remain confidential, options for floppy disk emulation are available, including devices from brands like Gotek. Despite floppy disks being considered obsolete for most individuals, government bodies and industries with established systems have been slower to move away from this outdated storage medium. Japan only recently stopped using floppy disks in governmental systems, and the San Francisco Municipal Transportation Agency plans to continue using 5ΒΌ-inch floppy disks for the Muni Metro light rail system until 2030.
In addition to government use, various industries such as Chuck E. Cheese and professional embroiderers still rely on floppy disks to operate machines like animatronics and embroidery machines. The transition from floppy disks to more modern storage solutions represents a necessary step in keeping up with technological advancements and ensuring the efficiency and reliability of critical systems.
