Fuso initially sails alone because its sister ship is still under construction. That second battleship could join the Grand Fleet after completion in March 1917. The next two ships are due to enter service in December 1917 and April 1918. Accelerating those ships, both laid down in 1915, might eventually produce a four-ship Japanese battle squadron. The proposal depends on bringing later completions forward, without establishing a firm date for the full formation.

More Japanese battleships could form a full squadron
Fuso's sister could join in 1917, while accelerated construction of two later ships might eventually create a four-ship Japanese battle squadron.
