Use two Type 0 Recon  (not observation) planes, and it's enough. Should give ~7.6 LOS, and ~50.8 LOS Cn4 iirc.

I'm assuming that you have all submarines at level 99 and Kai'd. but even if you don't (about level 70), the Recon planes should be enough.

If you don't have Recons, use 2 Type 0 Observation Planes and 1 Periscope (reward from E2N/H). Or 3  Type 0 Observation Planes.
