IMHO Gaijin should diversify the top tier tech trees of USSR/Russia once they start adding all the Sukhoi-27 derivatives by adding each variant to a specific tech tree, i.e Su-33 in Yak-141 line
as it is a naval craft, 27, 30 and others under Mig-29, and 34 and such obviously after the Rooks or the Mig-27K
Some beautiful (definitely not classified) Sukhoi Su-30SM blueprints for the forum users to enjoy while waiting.
