Or negative armor.
Isn't the chance to destroy the missile dmg/armor?
So, 4 dmg/-2 armor is a -50% chance of destruction.
That'll break it, I'm sure.
Hey, back when I discovered ECM was broken, I had a missile with 100 (1 size, max tech) ECM and 150km/s speed, versus a target above 100k tons with a speed of around 300.
The CIWS ALL missed despite eccm 10 because they couldn't hit the missiles, after which the missiles all magically vanished with an error report, which went completely unnoticed and is probably not fixed yet.
Play around with it.
It'll allow you some awesome RP.
You know, technically, a size 100 missile should contain enough explosives in a shaped charge warhead to split a small planet.
Or create a temporary black hole.
But yeah, it is cheating yourself.
Unless it's part of the RP.
