**Dev tweet says [[Battery Imp]]s are immune to [[Type 3 Shell]]s but there are many reports of CAs and BBs doing high damage to them in yasen.

**If you have enough [[WG42]] then you may want to use [[Ooyodo]] or [[Gotland]] and equip her with 2 of them as they stack and can deliver severe damage and can easily one shot an Imp or one of the Hime.

**Stacking [[Type 2 Ka-Mi Tank]] and [[Daihatsu-class Landing Craft (Type 89 Medium Tanks & Marines)]] upgraded with [[WG42]] can do a lot of damage to [[Supply Depot Princess]] and [[Battery Imp]].

===Regarding [[Land-Based Air Squadron]]s===

*You are permitted to use 1 [[Land-Based Air Squadron]]. There are no air raids on this map.

*Upon completing the quest B80 and F43, you will earn a Construction Team to gain access to your [[Land-Based Air Squadron]], which is '''highly recommended''' to help simplify the battle on the boss node for this map.

**3 Land Based Bombers and 1 Fighters is an alternative recommendation, if you want to have a better shot at damaging the installations, but may result in your losing planes more and also will likely lose your Land Based Attack Bombers' expertise in the process.

**Another alternative is to bring 4 Land Based Bombers and focus them on C node instead of the boss node. Plane loss here is minimal. This can significantly improve the pass rate of an [[Akitsushima]] / [[Nagato]] Kai Ni fleet which emphasizes anti-installation over anti-ship performance.

*This map can also serve as a good location to train your Land Based attack planes to max expertise. Bring only Land Based Attackers with a distances of 8 or more as they will reach enough distance to allow you to use Maruyu solo on the submarine node on Node M which your planes should target in order to train them.

** It's highly recommended to have a seaplane fighter or an Italian ship to help aid you in maintaining air superiority / air parity over the fights on your way to the boss. However, if you have her, Ise Kai Ni can pretty much guarantee air superiority, and even give a good chance for air supremacy at the boss when combined with the aforementioned (and still have two free slots after making fast, if given the RE slot).

**DDs and CLs are recommended to have [[WG42]]s and [[Daihatsu]] as these are the only effective ways to do damage to the [[Battery Imp]]s and do decent chipping damage to the [[Isolated Island Princess]], CAs and BBs should be armed with a [[Type 3 Shell]] against the installation bosses. BBs may also bring AP shells to help aid in doing daytime battle damage.

**In this case Akitsushima should be armed with at least 2 seaplane fighters as her role will serve to be a distraction and to maintain a degree of air superiority at the boss node depending on the formation.

**LBAS can be used preboss to help bypass easier, but may suffer the boss fight if you lack of good anti-installation equipment.

**LBAS can be used on preboss pass them more easily, but you may suffer on the boss fight if you lack good anti-installation equipment.

**Keep in mind that [[Artillery Imp]] at the boss node have fairly high AA that can easily wipe your bombers on your CVs. Do consider the bombers that have AA resistance so that your CV can at least do the shelling and take out some of the escort enemies.

**CAV can be replaced with LHA to '''skip node I''', which is an air raid node, but LHA may have some issue surviving the preboss.
