For civilian use but perhaps not in the West German Military. I say West Germany because the ships were ordered in June of 1989 and the Berlin Wall didn’t come down until November.
Europe in general, and Germany in particular, had some very peculiar technology quirks and companies back then.
Edit: It’s worth noting that while the contract was awarded in June of 1988 the ship design was being done in 87/88 which means the targeting system was probably designed in 85/86 when the 8" floppy was still prevalent, especially in Industrial and Commercial applications.
