Event Ship Locks (Tags) Explained

In many events, a ship gets a tag (出撃識別札, Shutsugeki Shikibetsu Fuda; players just say 札, fuda) for the first event map it sorties into. The tag can't be changed or removed until the event ends.

On Normal and Hard, a tagged ship can't sortie into maps that use a different tag. On Easy and Casual, you can ignore the restriction.

So the one thing to avoid is sending your best ships into an early map on Normal/Hard and then finding them locked out of the final map.

• The tag is the one for the first tag-giving map a ship sorties into. If a ship already has a tag, sortieing elsewhere doesn't change it.
• Tags are applied on every difficulty — what changes is whether they restrict you.
• Hard and Normal: a tagged ship can't sortie into event maps that use a different tag.
• Easy and Casual: tagged ships can sortie anywhere. But being allowed to sortie isn't the same as getting the route you want — some maps still need a fleet with matching tags for routing, even on lower difficulties.
• Tags are per individual ship. An untagged duplicate of the same ship can go to a different map.
• Regular maps, expeditions and exercises ignore tags completely.
• In some events the restrictions are lifted once every map is cleared, even on Normal/Hard.

During an event, the ship list in Organize (編成, Hensei) gets an extra filter at the right end of the ship-type filters. Click it to cycle 全艦艇 (all ships) → 作戦参加 (Sakusen Sanka, tagged / in the operation) → 待機中 (Taikichū, untagged / on standby).

1. 1Before your first sortie, check which maps share a tag. The event's map guide usually lists them.
2. 2Decide which map needs your strongest ships — usually the last one — and keep them out of earlier maps that use a different tag.
3. 3Clear early maps with the ships you can spare. Untagged duplicates are useful here.
4. 4If you're not sure you can finish on Normal/Hard, playing on Easy or Casual removes the problem entirely.

Can I remove a tag?

No. Tags can't be changed or removed by any means until the event ends.

Do tags affect regular maps?

No — only event maps. Regular maps, expeditions and exercises work as usual.

I'm on Easy. Do tags matter at all?

They're still applied, and occasionally a route needs matching tags, but they won't block you from sortieing.

Do tags carry over to the next event?

No — restrictions are lifted when the event ends.
