Bug in Spoiler missiles?

[IanD (OP)]

I had a survey ship approximately 13m k from a Precursor missile base. Well over a dozen 14 missile salvos failed to overwhelm a defence of 5 x 20cm lasers. which had to only intercept one missile or very occasionally two and once three, while some salvos missed entirely. This is not what I expect. My survey ship should have been destroyed several times times over, and would have in VB6. I captured one of these bases and attach it in case there is an error in the design. I do not have full specs on the missiles but they travel at 26,000+ k/s, approximately 5 x faster than my survey ship.

What's the design of your survey ship? During the combat were there any missile hits on your ship or did the ones that evaded your PD all miss their mark?

The ship suffered zero hits, appearing to only intercept missiles those that would have hit, all the other missiles missed. Something seems broken. I am not sure but do not think I see the same effect with the size 1 missile storm, but am in no way sure as there are usually at least 88 missiles in each salvo group.

Probably the ECM-60 on your ship , that will cut the hit chance down a lot as there is no ECCM on the launchers or missiles being fired at you

If i remember the ECM calculations right that 60 is a 60% reduction in hit chance, id say its definitely the ECM

[nuclearslurpee]

It's definitely the ECM. Remember that ECM is subtracted from accuracy, it is not a multiplier. NPR missiles typically have very low maneuver ratings, so even if they have 5x your ship speed their %CTH is usually only in the 50% to 60% range, and ECM-60 will subtract 60% from that leaving 0% chance to hit.

OK I had assumed ECM was the same as VB6 Aurora where it reduced the range you could engage at, not the accuracy.
Sorry for the false alarm

Well it still kinda does that for beam combat....
