out of the eight missle I had a 2 missle launch successfully
and that was a good set other times I had none

The initial missile design had a heavy armor tip but every time I fired the added mass made the missile slam the missile rack. The only way I got past that was to reduce the tip mass to prevent the swing again.

By design the idea was to have the missile penetrate into a ship and explode after a tiny delay for maximum damage, however it was too unreliable for my tastes and I had to go back to light armor tip...

for 1 having a full heavy armour penetator tip already helps a lot

I can help you with your missile designs, if you like

You'll need to open up everything hidden and set absolutely every piece as pirate. Can't see why it wouldn't fire at you.

@OctoMoose and what if i change it to a pirate ownership? will it attack me? =3 cos i wanna fight it

Just paste it from BP menu. It is active and ready and will shoot at hostile signatures automatically.

so.. how do i use it? o.o?
