Costs about 130~ bauxite per run (i didn't use any torpedo bomber tho) so its not that expensive.

Usually you spent 250-350 per sortie (costs more if you go night battle at boss node and/or using slow fleet because whirlpool) with A-E-H-M-O. Do note you cost less fuel due to M node

You can skip the drum requirement so you take node K instead of M for more exp, but i don't recommend that.
