Ventures with Sparks. Why not?
I'm not sure if you're being sarcastic here or not, but now that I think of it: Yeah, the Venture and the Tempest are the two other ships that have in-built fighters, and I don't see why they couldn't use this proposed system either (That is, have their default, 0 AP fighter option as a fallback if the slot is empty, but be able to override it with one of the unmanned options if you're willing to pay the price in AP). The Venture is a bit crap right now, anyway, and having access to a better fighter squadron than mining drones would be a welcome upgrade in addition to the possibility of installing military subsystems permanently in the next version. It might actually be worth a damn after that! For the Tempest, I'm less sure about replacing the two existing Terminator drones, because it's already kind of starved for AP, and paying 5 extra for a bunch of Wasps or 8 for Sparks might cripple its overall usefulness. But if the player
wanted to, why not? It's all single-player, anyway, and you could program the AI not to touch in-built fighter bays.
On the idea of a regular quality frigate carrier: Sure, as long as spamming 30 of them won't break the game in half, I'm all for more tactical variety. That said, this is a problem you'll definitely never have even with 30 of the Shepherds I am proposing, haha! The only thing that'll break in half in a large fleet engagement is them.
