USS Yorktown II

3s after the battle starts: launches a recon squadron consisting of AD-1 Skyraiders, inflicting the Marked debuff to a random enemy (prioritizing humanoid enemies) for 12s and decreasing that enemy's AA by 6.0%. 12s after this effect activates, or after the Marked enemy is sunk: restores 3.0% of this ship's max HP and launches another AD-1 Skyraider squadron (this HP recovery effect can only activate up to 5 times per battle). When this ship launches an airstrike, if she has Eagle Union aircraft equipped: launches a Lv.10 special airstrike (DMG is based on the skill's level).

When the battle starts, if there are 3 or more Eagle Union ships afloat in your fleet: increases this ship's AVI and ACC by 15.0%. Every 18s after the battle starts: 100.0% chance to fire a Lv.10 special barrage (DMG is based on the skill's level) and decreases this ship's Detection Gauge value by 2 once a second for 5s. While this ship is afloat, for the first 4 battles another fleet fights during a sortie: increases the FP of that fleet's Main Fleet Eagle Union ships by 6.0%; 20s after that fleet's battle starts: fires a Lv.10 special barrage (DMG is based on the skill's level).

When this ship launches an airstrike: decreases your Yorktown-class CVs' airstrike loading time by 10.0% and decreases it by 8.0% for your other Essex-class CVs (only affects the currently loading airstrike once; effect does not stack). Your Yorktown-class and Essex-class CVs gain the following effects during battle: 1) increases their DMG dealt by 10.0%; 2) when they launch an airstrike: also launches a Lv.10 interceptive airstrike (DMG is based on the skill's level).
