A complete ripoff of the Russian nation's idea.
The fast cruiser will be build late in the year tied to the story as a repayment to the Iberian help for helping in the infrastructure and as a way for the Iberians to counter the Mexican fast cruisers, pretty much a political message showing the world the strength of our alliance.
