Her Commanding Officer was Oberleutnant zur See Gunter Rabe and she was assigned to the 9th S-Boot Flotilla (commanded by Korvettenkapitän Götz Freiherr von Mirbach, one of the most famous S-Boot commanders of the war) to reinforce their presence in the Southern North Sea. They operated out of Rotterdam until mid-February 1944, when they re-deployed to Cherbourg in order to reinforce the 5th Flotilla (under Korvettenkapitän Bernd Klug) in their operations throughout the Central and Western Channel area. Throughout her service, her radio callsign was “Rabe” (Raven), her dashing Master was known by all in the 5th and 9th Flotillas as “The Raven” and she wore a ship’s crest incorporating a raven in addition to the usual 9th Flotilla sign.

You can just make out the Baltenschwert behind S130’s starboard torpedo tube. Not sure what else is there
