The U-612 used during filming is a non-diving u-boat replica of the US Navy submarine S-33 built in Valetta, Malta. It was heavily modified but is the same watercraft used for U-571 (2000).
If you are able to watch this show without comparing it to the legendary movie, you should have a real good time. The show is more than well done. The actors are great and I cannot wait for season 2. It doesn't deserve the low star ratings at all.
