Das Boot is probably the most realistic. For more drama, Crimson Tide is a good watch. The Hunt For Red October is more of a fantasy, but also good drama.

It's funny because Crimson Tide is picked out here as one of the least realistic.

The mention some alternative modern movies instead

		No disagreement here. Perhaps I wasn't clear enough when I prefixed the alternatives with "for more drama." Drama is usually unrealistic.
