German Navy still uses 8-inch floppy disks, working on emulating a replacement

The German Navy is upgrading its F123 frigates by replacing outdated floppy disks with an emulation system developed by Saab. The modernization includes new radars and is expected to finish by July 31, 2025.

German Navy still uses 8-inch floppy disks, working on emulating a replacement

The German Navy is in the process of modernizing its Brandenburg-class F123 frigates by replacing their outdated 8-inch floppy disks used in onboard data acquisition systems. These systems are crucial for controlling the frigates, especially for functions like power generation. Despite the availability of modern alternatives, the Navy has stuck with floppies due to their perceived reliability. Instead of a complete overhaul, the plan is to develop and integrate an onboard emulation system to replace the floppy disks. Saab has been contracted for the updates, including the integration of new naval radars and fire control directors. The replacement process is expected to start on October 1 and conclude by July 31, 2025. The F123 frigates will remain in service until the newer F126s are available, estimated between 2028 and 2031. The transition away from floppy disks is a trend seen not only in the German Navy and US Air Force but also in other sectors like government agencies and industries where legacy systems are deeply entrenched.

In Germany, there is a saying:

„Das haben wir schon immer so gemacht. Das haben wir noch nie anders gemacht. Da könnte ja jeder kommen.“

In English, this roughly means:

"We have always done it this way. We have never done it differently. Anyone could come along and say that."

That explains a lot.

In Germany, long-established and entrenched processes and technologies are often confused with being reliable and safe.

Fax machines are still widely used, particularly in public administration and larger organizations in general.

The preposterous as well as appalling argument often heard in favour of this is that "fax is more secure than email" and somehow doesn't put privacy and the sacred German "data protection" at risk (because said data protection seemingly on applies to digital stuff).

Famously - or rather notoriously, during the pandemic local German health authorities faxed case numbers and other relevant data to federal authorities, which led to massively delayed response times and a general unavailability of dependable, actionable data.

i started on Unix/SunOS in 1990 then Linux in 1993 (i'm old) and even i have never even _seen_ a real 8" FD! i do recall using 5 1/4" FDs (though i can't remember what for).

Dear German Navy. I have built disk emulators before[1]. Please contact me if you need help :D

What a weird thing to focus on. Even a modern warship is probably full of 74 series logic ICs which predate 8-inch floppies by several years. If the floppies did the job in 1994, why shouldn't they today? It's the same ship after all.

Can anyone speak to why those systems were considered more reliable? Are world agencies relying on this technology because of the inherent risk of rebuilding systems, or because of some attractive property of floppy disks?

If someone were to offer me $436 million to replace some 8 inch floppy disks, I could probably use $435 million of it to build some pretty interesting products that have nothing to do with floppy disks...

I wonder if there is a military grade chip equivalent to an Raspberry Pi? Or more ideally a RISC-V system that's similar.

Replacement could begin by emulating the 8 inch floppy drive's electrical interface and attaching a modern system.

The storage media should probably be some sort of flash memory rated for military use; I don't anticipate the size as an issue, nor most of the other specs.

The most critical factor is selecting a storage media that's intended for production and support for the next 50 years, since it seems clear these systems will _never_ be updated again.

Man, this would be fun to work on. Anyone know if they have any contracts open for bidding?

Makes sense. If I pick up an 8-inch or 5¼-inch and put it in a a maintained drive it WILL read it, try that with a writable CD/DVD. Don't get me started on the bit-rot you can expect from a 2024 NVMe

It looks like these ships were laid down in '92, and commissioned a few years later, which seems very late to use 8" floppies.

Just upgrade to 3.5" ones and call it a day.

In high school we had a couple of (old even back then) Wang PCs with 8" floppy disks. The jokes wrote themselves.
