Over-Conservative Torpedoes

[Erebus]

I'm new to the game, so maybe this is something I'm doing wrong. But I attempted to take a crack at the Semi-Dreadnought mission with a heavy cruiser that's fast, light, and armed with torpedos. Along with two other light cruisers which also had torpedos, I got close to the battleship and waited for the torpedoes to start firing. They didn't. You can see in the image below; the light cruiser selected had its torpedoes set to aggressive. The heavy cruiser's were also set to Aggressive. Despite this, even when I approached the battleships with two ships, neither of them fired and they promptly got destroyed. This is pretty dumb, considering I've had situations where I approached AI-controlled ships which launched torpedoes that were accurate, well-timed and well-aimed at me and wreaked havoc on my own ships. What am I doing wrong here, or is this an issue on the game's end?

Curiously that's the same issue Rule The Waves (1 and 2) has, where the AI "Magically" (Wink wink,  cheating) launches at least three times as many torpedoes in any given engagement.

your using underwater torpedo mounts they have very constricted launch arcs 
that was most likely your problem here
