Unless I'm mistaking it for another one its not actually needed for unlocking Z3.

Try : S rank T and get Perfect air defense/AS during a base raid twice, that should unlock Z3. And yes you have to do that with a STF.

I suggest trying the CTF route for the kill though, as the princess on T can easily damage one or more of your ships, making it likely for them to get shot into critical condition on Node M.

You still need to get there with a STF once though, to debuff the boss. (Although on casual you shouldn't need to debuff the boss)
