EW FACs that can hit >10,000km/s are excellent for dealing with Swarm if you can gather the critical mass needed to out-DPS Queen shields; they'll be fairly rubbish against Invaders without a large tech advantage, and they'll probably do decently well against NPRs with poor sensor/FC tech. You'll want to invest RP in compact ECM, though. And I can't see low-med tech S1 missles being particularly strong, so I'm guessing that you're sandpapering the Precursors. Note that that only works because you're able to engage without taking fire and because Precursors have no shields and shitty armor.
I generally take the precursors out with a single salvo, but that's mostly because a salvo is a ridiculous amount of missiles. If I have a fleet of 12 FACs, and have them fire about 8 to 12 missiles each in a salvo (generally enough to destroy the enemy ships), it means I'm hitting them with about 96 to 144 damage 4 missiles. If I fire the whole arsenal, each FAC is firing 46 missiles, for a total of 552 damage 4 missiles for a twelve ship fleet.
EW FACs as in microwave armed ships, right?
Nonono. EW = Energy Weapons. Microwaves do nothing but fry electronics and burn shields, and are support weapons at best. The ideal would probably be a 10cm laser per FAC or a reduced size 20cm (or thereabouts); you basically just want to be able to beat the 10,000km/s that the Soldiers can pull while also having enough DPS to burn through the Queen's fast-regen shields.
Anyhow, been burning through my research while turtling for 35 years in my current game, and I had 1000% difficulty mod NPRs as well as all 3 special enemies on the entire time. I finally decide to break my self-imposed isolation. The very first jump out of Sol?
Heheheheh. Fun times ahead.
My current OOB isn't too poor.

I'm planning on moving the
Sunas to an asteroid to interdict pushes from the JP, which rather unfortunately has an ancient JG on it. I've also got a heavy cruiser design drawn up, but none of my yards can handle it yet.
