I couldn't find any explanation of the "prototype." I'm guessing this is a Yamato with maybe 6x 20" guns and even more AA? It is surely not an A150.
From what I recall some of the A150 designs were just Yamato with the 508mm main battery and changed AA suite; Fujimi has a similar kit in 700.
More likely that this one is based off the Shikishima from WoWS (which is a Yamato with different main battery and AA) as the camo on the box art seems to match, and also the secondary battery looks like Akizuki mounts which is the same as on the WoWS model and diffferent from the Fujimi kit.
