Soviet style cosmodrome.

Currently We have American style. Where in special building rocket is constructed and then transported by special crawler to launchpad.

But how about do it in soviet style? Also this can expand production chain.
Sp soviets do rockets chasis in one factory, then transport it to assembly plant by railroad. Engines constructed in another plant. And then they transported by heavy trucks or railroad into that assembly plant. And payload constructed again in another factory. In assembly plant rocket can by fully assembled and then transported by railroad to launchpad. Railroad from assembly plant to launchpad must by on flat surface. Also you need to construct special train for rocket transport. Also this train transport rocket in horizontal postion and on launchpad erects rocket verticaly.

The maximum payload depends on the type of engines installed. I suggest at least three levels of engines. The first is a standard kerosene-oxygen open cycle engine - a simple and reliable engine, but it
