Somebody didn't check their history

I think we can already deduce what has happened, since the admins asked us frontiersmen to keep it a secret they pretty much blew the game from the off, so here goes. I recommend you adjust your tech tree given this information. P.S anybody asks me stats whether or not it works etc will be told to stick it My pain is over

Three carrier classes are wrong for the Russian tech tree.

This is the moskva

This ihttps://en.wikipedia.org/wiki/Kiev-class_aircraft_carriers the Kiev, which was NOT nuclear powered.

The Only Russian carrier with nuclear propulsion except for the recent unveiling of a new class to replace the Kuznetzov was the Ulyanovsk and was scrapped on the slipway
