While torpedoes in DW are extremely easy to hear, this does of course not apply to torpedoes in the real world, at least not in general from what I know.
The Seawolf is quite the silent bastard, I reckon (how many times has my Kilo met the bottom? Lost count.), so I was thinking, "Why don't they make the torpedoes equally silent?".
Could anyone answer that? And what is it that makes the Seawolf so quiet? Links to information would be rather splendid, too.
