Not generally possible. Scout defense.
I'm in the process of building PD within his PD for one planet, then will spam blackbirds onto his planet to "target" his ships. What I want to know is if PD happens before planetary assault, and if PD can shoot ships set to "planetary defense" on other planets. If it does, I might be able to PD through Oldry's scouts if he tries a scout defense, and thereby launch an invasion fleet. I have 1.5 million steel saved up for the attack. Goal is 3 million. If I fail, then I will have learned that it is, in fact, impossible to conquer an actively defended planet. If you can't do it with the assistance of PD and 3 million steel, then I just don't believe you can do it.
Nope, PD takes place after assaults but before fleet combat.
