Try crafting at least 2 Saiuns more to extend your LBAS range to a max. of 8 if you're going to operate them with Reppuu and Suisei and/or Ryuusei. Since this is a small-scale event the probabilities of enemy air raids are low, but prepare extra fighters for base defense  (3~4 Shiden Kai Ni is fine for this job), or otherwise your resources won't last as much as you projected.

I'd recommend you to read this article to understand more about LBAS mechanics.
