Torpedo tubes that launch at 50m depth.

As long as you never surface at all, only use diesels and the snorkel for charging batteries and attack convoys from below 40m depth you are almost invincible.

Interesting. Just how does one use a Type XXI in SH3, taking full advantage of its capabilities, as opposed to using it like a glorified Type VII/IX?
