Territory battles stage 6 ships

Edit: I think the person below me is actually correct, my mistake.

6

For Phase 6, it's 6* ships for the combat mission and 7* ships to donate to the squadrons.

Oh yeah good call. I was just thinking for combat.

Once you get a team of ships (with well geared pilots) the battle is quite easy.
(Much easier than the phase 6 ground combats.)
No strategy required, just bang away with whatever ships you have.
