@Jens: I think it's because of a cooperation between Germany and Norway.
@Emmanuel: U36 is the name, S186 the Pennant number.
@miraflores: U36 is at the degaussing facility near Rendsburg.

Hello Emmanuel,

U36 is the name of the boat, S186 the NATO pennant.

So she is ... both!

Best regards,

Michael.

U 36 hit a rock in norwegian waters on 16. May 2019, I think they were on a sea trial escorted by navy tug FGS Borby. Both AIS signals are still near ferrypoint Sehestedt, but they didn't pass the Kiel Canal in full.
MMSI 211931000
MMSI 211212560

Is she the U36 or the S186 ?

Nice one @fabianv

Lucky you she didn't travel through Kiel Canal submerged! :-)) Nice catch.

Do you happen to know what the Norwegian flag is supposed to mean?

Cheers,
Jens
