Honestly, for ballistic missile, they seem to be kinda .. slow (or maybe that's just my ups problems)
I think they should be much faster than artillery
So, I propose, adding a new circuit input signal, B(oost).
Any value on if > 1 would increase the missile speed, but also fuel used quadratically

I've read the mod code and it seems doable, if not, you could just add a speed setting instead?

BTW, do you have a github repo for the mod?
Would be nice.

Sorry for coming back to you so late - not much time for modding for some time.
That's a good suggestion, thanks. It would definitely be possible without to much work.

There is only one problem. Fuel consumption is calculated carefully at the moment to provide (almost) infinite range when full.
Increasing the speed with a boost signal would therefore drastically reduce the range - I hope the silo would still be viable.
