Just throwing this against the wall, but might strike craft be better off flying and fighting as a wing? Basically have them set as a pseudo-ship that flies toward the opposing fleet and then paces its target vessel, while the "individual" craft change their visible formation to mimic the tight-turning swarm desired. Mechanically, it might work closer to a single ship with full-rotation turrets, with the "hit point losses reduce effectiveness" being closer to "% effectiveness = % hit points" - perhaps in more discrete blocks - to simulate the more 1:1 ratio of "craft" to firepower. Reinforcing the wing would differ significantly from current, as unless the entire wing is destroyed, the replacement craft would appear as part of the wing at its location and not necessarily visible travelling between the carrier and the wing (although maybe as basically a projectile). Changing to a single target for flak and PD would require some additional balancing.
Just a thought...
I like the idea. Solves two problems, one having to balance stike craft damage against L slots used on battleships, and two the problem of all fighters being erased from battle when their carrier dies. Might be easier for them to balance if they were their own ship class as well. And yeah, the reinforcement thing would be an issue, but perhaps they could make that the unique mechanic benefit of a strike craft wing over a corvette. You pay for the damaged strike craft wing like you would any new vessel, but perhaps they would instantly spawn into their wing instead of travelling across the map.
However, they would have to add a whole new ship class with it's own unique mechanics, and that is a bit a work, and considering what has been done with strike craft so far, they don't seem super high on their "total overhaul" list of things to do which is why many of the suggestions in this thread try to envision them within game systems that are already in place.
I rather like the idea though
Ooo, or these strike craft wings would spawn from cruisers/battleships. Few ways you could do this, for every cruiser or battleship sized vessel, you are also allowed to build "x" amount of fighters to accompany them, and this build option is available from the fleet overview when you click on that fleet. Another idea the "Hangar" slot becomes sort of a mobile shipyard that can only build fighters, and each Hangar slot increases the "command point limit" for fighters that the fleet can sustain. If the carrier dies, the remaining fighters stay with the fleet, but they can't reinforce until their "command point limit" is restored.
Again, love the idea, but as you can see, it just sent me down a rabbit hole that would probably work great, but also require quite a bit of dev time, time I think they'd rather spend elsewhere.
