On ideal condition, 4 type 3 shells are required to ensure destruction for installation-type bosses.

How you recognize installation-type bosses:

- They always have kanji written "姫" on their left, with super holo rarity level.

- They usually have cannons and 3 different plane types, or may be just stack of 4 different plane types like aircraft carriers.

- Below them (#2 & #3 enemy ship, or rest of #2 to #6 place) always have Escort Fortresses (indicated by kanji " 浮"  written on their left with 66 HP)

You also need more recon planes and radars, since every event map require certain amount of LOS value to reach the boss node.
