If I may suggest, then I would recommend you to get at least 4 reppu minimum and 6 reppu recommended. As there are some LBAS anti-air ability required for boss raid, reppu is quite useful in both for LBAS and CV equipment.

In advance, you might required to get seaplanes which extends LBAS' flight range. Atitsushima would be good farmable shipgirl to get type 2 seaplane. Usually those reppus are not capable enough get far and help out your fleet in boss nodes.

Those aerial dominance system is quite important in boss raids and last dances for better shelling and accuracy. I think that's real pain in the arse.
