@whiskydeltagolf4555 considering they were looking at 18" guns and displacements well in excess of 35,000 I would say they were not really concerned with treaty restrictions. By the time they actually laid anything down for Sovetsky Soyuz, at nearly 60,000, intelligence reports on Yamato had already tripped the tonnage escalator clause in Second London, and the UK and US had agreed on a new 45,000 ton limit, which the Russian ships exceeded. Had Sovetsky Soyuz been laid down earlier, it would have tripped the tonnage escalator before Yamato did. I just skimmed over First London, and did not see a tonnage escalator, so, assuming Sovetsky Soyuz was laid down in 36, or earlier, to the 60,000 ton design, the displacement limit in Second London would probably have been negotiated higher at that time, rather than the tonnage escalator left to be negotiated later. That would have the KGVs being laid down to the Lion design, and the Iowas being built rather than the South Dakotas and North Carolinas.
