Fire nation Navy vs separatist battleship

Let's also assume that the lucrehulk is in low enough orbit to actually engage with the fire nation fleet. The lucrehulk will have vulture droids, hyena bombers and landers, obviously 😁

Let's say it's the entire naval capability of the end of 100 year war fire nation (say over 100 light cruisers and 1,000 heavy battleships), including all airships available (500 or so), vs a single lucrehulk class battleship from the confederacy of independent systems.

Just to make this fight as fair as possible

If the entire Fire Nation Navy learns lightning-bending, they can short-circuit the Lucrehulk's systems then destroy the rest of the enemies with fire.

Possible. But highly improbable.

Bro… The space ship destroys as Fire nation guns can’t reach

Yep
