If you already unlock Route 2, you can put 2 LBAS to attack node G which is dangerous for your submarines and 1 of your LBAS to node F for avoid being knocked by Sub Hime.

But, if you are not unlocked Route 2 yet, you can put 1 LBAS to node A, 1 LBAS to node G, and 1 LBAS to node F or 1 LBAS to node A and 2 LBAS to node G. All remaining nodes are not dangerous as like as node A and G for your submarine if they are not well-leveled. Or, you can put EMP (Emergency Repair Personnel) to all of your submarine to prevent their sinking into the depth of the abyss. It's your call.

Good luck.
