Special

Mainz B — German special premium Tier VIII cruiser.

In 1936, Germany ordered two cruisers armed with 150 mm guns housed in four triple-gun turrets. However, the cruisers were designed in such a way that their barbettes were identical to those of cruisers carrying 203 mm guns, which could easily be mounted instead of the 150 mm ones. That replacement was made in 1937, even before the ships had been launched.

Mainz B was first released for sale on DD MMM YYYY.
