With the underwater camera mod out I think it's appropriate to release a fun weapon that can be used with it. Yes it is a rocket, and the reason it's a rocket is because they don't disappear underwater. After a frustrating time dealing with a particularly annoying glitch I finally found and solved it. Now this thing is fully functional! (in fact it's in a couple of my builds).

Use Yaw to turn, and trim to adjust depth (For hitting submarines). Best used against player created ships and subs, as the beast will shrug this thing off like a mosquito bite.

If you want you can add fuselages over it to make it look like a MK-48 or other torp of your choice, it's made for function more than looks. XML adjustments to the Gyro's yaw power is recommended, as the turn rate of this thing is mysteriously linked to the size of the build.

I am also cool with (and would love) people using this as a base for their own torpedo designs!
