This branch preserves a delay between the European and Pacific wars. It gives Japan additional time to complete Shinano as a battleship and proceed with a fourth sister. Those ships create a projected force of four Yamatos. The estimate therefore relies on several more years of construction and does not describe a four-ship force available at the start of 1942. Knowledge of that force would also give other navies time to consider their own responses.

Four Yamatos belong to the later 1944 Pacific scenario
The four-ship estimate assumes Europe goes to war in 1942 and the Pacific conflict follows later, around 1944.
