I can't seem to get 10, at least without severely crippling my output per wave.
9->8 missiles per wave on my frigates nets me a bit more than 7 salvoes up from 4.
18->15 missiles per wave on my destroyer has the same effect.
I'm a bit wary of decreasing the wave size as well, since I estimate wave size to have a square-law effect. More per wave = more get through = more damage = less they can shoot down your missiles next wave.
Just eyeballing the stats from my escort frigates vs my offensive frigates tells me that my offensive frigate cannot even touch my escort.
Sure, they cost about 80% that of an escort, but the escort has 15 AMMs per wave, ROF 10, 16 salvoes... =(
- Interception chance is roughly 60% as well... =( With a 6 million km interception radius. =(
- The current OOB of my fleet tells me that all my offensive frigates can shoot dry onto my escort frigates and they won't even take a scratch. Maybe a few hits at most, which my armour is design to tank exactly one hit.
- The only one that gets through is the FAC swarm box launcher alpha strike which is 160 missiles and is just ridiculously big.
Also because I don't want to waste missiles. Like you say, you never have enough.
1.5k AS missiles after 2 years of building missiles = 10 minutes of firing total from my ships
5k AM missiles (I split 50-50 between AS and AM) = 12 minutes of firing total from my escorts
