Greetings, Admiral.

In ROS, the Warship Carrier is the only object that allows you to mine or loot Silther Particles.

The Event Warship Carriers, which were provided so everyone could enjoy all 100% of the mining content, will soon be expired.

Once your Event Warship Carriers are expired, they cannot deploy to mine or loot Silther Particles.
We highly recommend that you upgrade your Event Warship Carriers to T1, if you have not done so yet.

You can still see your Warship Carrier in the Warship Carrier Lab even after expiration,
and you may upgrade its tier at your convenience to make it permanent,
so don't forget to tier-up your Event Warship Carrier!

Thank you.
