USS Essex

When this ship launches an Airstrike: launches an additional Lv.10 TBF Avenger airstrike that causes Flooding DoT to enemies hit by their torpedoes (Flooding DMG is based on this ship's AVI stat and the skill's level.) Also increases this ship's DMG to enemy BBs (but not BCs or BBVs) by 10.0%.

Increases this ship's AVI and AA by 5.0% for each Eagle Union CV and CVL in the same fleet. When this ship's aircraft shoot down an enemy aircraft: gains 1 stack of Killer Formation (increases this ship's AVI by 3.0%; can be stacked up to 5 times).

When there are 4 or more Eagle Union ships in the same fleet as this ship: 12.0% chance to reduce DMG taken to 1 when a ship in your fleet is attacked by enemy Torpedo Bombers or Dive Bombers.

When the battle starts, and when this ship's airstrikes finish loading: fires a Lv.10 aerial barrage (DMG is based on the skill's level), gains 1 stack of Killer Formation, and deploys a shield (lasting 10s; can negate up to 8 enemy shells) around your frontmost Vanguard ship. If the shield created by this skill is destroyed during its active duration: restores 3.0% of your frontmost Vanguard ship's max HP. When a fleet this ship is NOT in starts a battle, while this ship is afloat: 25s after the battle starts, fires a Lv.10 supporting barrage (DMG is based on the skill's level).
