Not really sure but after some sortie clears i got it, so i guess it something like "defeat enemy fleet" or something...

I have a question too though. For some reason i can't buy the new outfit for VV, any idea what it says?

It was like 33-34 clears to unlock the quest.

Do you have enough diamonds/have VV? Haven't bought an outfit before though so it may be something else. I tried machine translating it but it didn't come out to anything useful: "Not in the purchase time".

I do have diamonds and the ship itself. I bought one of the older ooutfits with no problem. And if i try to buy something expensive it is different pop up. So i guess its really "not in purchase time". Maybe after one more update or something :D

I never would have noticed the new outfits if you hadn't have made a comment; I really like Warspite and Royal Oak too. Keeping the full rigging without making it too cute is my preferred style.
