USN Guns

There can be no set pattern size for any ship as on any given day the sea state is different and the ships heading with respect to the waves is different. This changes the pattern size.

As the sea state changes and ships heading changes with respect to the waves and troughs the bending and twisting of the ship changes. The bending and twisting of the ship changes the alignment of the roller paths of the turret, gun mounts and directors with respect to each other and affects the size of the pattern and the range of the MPI of salvos.

The pattern size can only apply to the ship on the day of firing and at the particular ships course in relation to the waves on that day. For these reasons the USN did not and could not produce a table that reflected an accurate pattern size for any ship, nor could any other navy.
