Last Japanese Battleship proposal

Ages ago (more like a decade or more...) I've found a mention on some naval sites and forums that even after the A-150 "Super" Yamato the Japanese considered building or designing  battleships surpassing even the size of the A-150 type! This design was known as the 100.000ton "Mega" Yamato. To my knowledge only two data was available about this mysterious proposal:
Based on this two data, knowledge on the Yamato preliminaries, the Yamatos themselves and the possible A-150 variants, this is my interpretation of this massive battleship armed with the most modern weapons and equipment of the Imperial Japanese Navy!
Like on the previous A-150 series I've put a second 15,5m range finder aft in place of Yamato's 10m secondary rangefinder and enlarged the main rangefinder atop the bridge to 17meters! I've also further enlarged the main superstructure bridge and conning tower compared to the A-150's.

Sidenote: It isn't impossible that the 100.000ton design was another A-150 variant with large size heavy armour and many guns!


With this drawing I officially done drawing all the Proto-Yamato, Pre-Yamato, Yamato Prelimianries, Yamato variants and Post-Yamato designs I've started in March!
