Same core rule as other class emblems: reach the required average damage over the last 100 Random Battles on eligible carriers. Plane cycles and strike tempo decide whether that window holds.

Unlike many surface First grades, several CV steps use Tier VIII and X (not IX–X). Typical averages: Third ~60k, Second ~71k, First ~84k on VIII/X; Elite ~113,000 on Tier X carriers. Always confirm in the client.

The Elite line (~113k average on Tier X) sits high for CVs. A streak of low-damage games resets a lot of progress in the rolling 100-battle window, so Elite needs consistent high-output carrier sessions.

List your VIII and X carriers in the order ticket. Support needs hulls that can sustain the grade you want — especially for Elite on Tier X.

No. Only aircraft carrier Random Battles feed this mark. Keep the account on the agreed CV schedule during the boost.

Yes. Enable Replays or Screenshots in Additional options if you want proof packs after completion.
