'Robbe' (i) was a U-boat wolfpack operation in the UK/Iceland gap against the SC.63 convoy (15/24 January 1942).

The wolfpack comprised U-94, U-586, U-587 and U-588, and for the loss of none of its own number sank two ships, the 4,271-ton Greek Dimitrios G. Themiotis and 5,851-ton British Caledonian Monarch. These succumbed to Kapitänleutnant Walter Schug’s U-86 and Kapitänleutnant Victor Vogel’s U-588 on 18 and 22 January respectively.
