[2021] Info for those planning their uses of coal, steel etc: UK T9 BB Marlborough will be Winter Dockyard.

Odd topic to Necro -
The Marlborough you have is on the Public Test Server.
It was expressly stated that, while you could complete stages in the Dockyard and obtain the Dreadnought, Repulse, and Marlborough, the only ship that could be played would be the Dreadnought. https://worldofwarships.com/en/news/public-test/public-test-01011/
