Just some eye candy: I got annoyed a long time ago at seeing electric torpedoes leaving the same surface trail of bubbles that steam ones did. So I made a mod to fix that, and this is just an updated one specifically for WAC 5.2.
Basically it makes the surface trail of steam torpedoes thicker, and last longer, while electric no longer leave any surface trail at all, only having a minor cavitation trail.
