[Missing Name]

The only British subs I've seen are escorts or in Lerwick. I've never engaged the escorts and the harbored boats are a pain to sink.

I've encountered and engaged American Gato-class submarines twice. Both times, they were heading south somewhat near the US coast. One was sunk from a distance (guess how). The other I gave up due to very poor weather and a lack of shells; I only knew he was there because of my RADAR detector.

It's not uncommon to see a friendly boat in the Bay of Biscay. VIIC's are most often in the U-FlaK config when it's available. I've encountered one a good distance into the mid-Atlantic.

And much to my annoyance, friendlies have disrupted convoy attacks on multiple occasions.
