For foreign submarine an interesting choice could be italian submarine "Luigi Torelli" aka UIT-25 for Kriegsmarine and I-504 for Imperial Japanese Navy.

I read that with a mixed Italian, Japanese and German crew  shot down a B-25 Mitchell bomber while under Japanese flag near the very end of the war in the Pacific, allegedly the last success by an Axis naval vessel in the conflict.

The Luigi Torelli and sister submarine Comandante Cappellini were the only two ships to fly the flags of all three main Axis powers during World War II.
