urgent game help needed (about mines) !!

[Ragnarok-X]

Hey everyone,

im in need of some game tips. In a recent game enemies are showing up in my sectors. I dont have defenses yet, so i decided to rush some mines. Now the problem is i need to construct the mines AND launch them BEFORE the enemy reaches my planet (all in one turn)

If i set my planet to build mines and choose the "remote launch" mines button, will the mines be constructed and launched before the movement phase (i.e. before the hostile ships attack my planet) or what will happen ?

thanks a bunch !!
