As I said... that works well against the computer controlled NPR's. but won't fair so well against a player controlled NPR with a fleet designed for a missile heavy environment, especially one designed with missile fighters and FAC's in the mix. It's a whole different game with both sides are actively controlled.
I don't know about fighters or FACs. They don't look that useful frankly. I do build 1kton corvettes because I built a 8 slipway naval yard that I might as well put to use building a reserve force and civilian garrison.
Fighters and FACs lug around an engine that is not being used while taking up room in your carrier, so despite box launchers, you have only slightly more tubes per weight than reduced size launchers, for high fuel cost, logistics difficulties (fighters need one more type of factory, FACs need small shipyards with alot of slipways) and reload times comparable to 33% launchers.
If the fleet scout packs a size 50 res 1 sensor (which mine does), no missile platform will get into firing range without being seen and shot at.
Note to self: check if I can reduce resolution of next gen firecontrol to maintain the same size of firecon, res16 isn't good enough for anti-fighter work.
Fighters have a problem countering ECM and if I add cloaking devices to the fleet, suddenly fighters are very hard to use (fighter mounted actives aren't going to be high res or long ranged); and I don't lose all that many launchers.
FACs are slightly better but if you're going to use box launchers, I think I will use missile pods packing ultra-long ranged drones.
A fleet designed for a missile-heavy environment could mean a fleet that is 33% tonnage of overcharged engines, relying on lasers for offense and PD as well as coming knocking with 50% or higher AMM escort frigates. AMMs are cheaper than ASMs after all.
If I had to build a fleet to counter my current one, cloaking devices and/or long range sniper drones would be the way I'd use. Either that or a fast laser-armed fleet with thousands of AMM launchers.
Unorthodox tactics could include a cloaked FAC that is nothing but armour and a meson to soak up AMMs. Size reduction launchers aren't that good at dealing with beam-armed FACs and spending AMMs against armour balls will be... expensive.
