They are to fast for Torpedos.

Can this be made for small ships (like how airplanes carry torpedos to sink carriers)?

It can't fire them at once.

does it fire all 3 tubes at once?

Please post more pictures and a video for us to see how it works, by the way, does it just move in a straight line or does it have a guidance system? Will you be making different types of torpedoes, like for example, HE, AP, Cluster, "airburst"(explodes close to its target releasing a shockwave that does superficial damage to armor and destroy exposed components on the surface like thrusters and turrets)?
