As modernized in the 1980s, each turret carried a DR-810 radar that measured the muzzle velocity of each gun,
which made it easier to predict the velocity of succeeding shots.
Together with the Mark 160 FCS and better propellant consistency,
these improvements made these weapons into the most accurate battleship-caliber guns ever made.
For example, during test shoots off Crete in 1987, fifteen shells were fired from 34,000 yards (31,900 m),
five from the right gun of each turret. The pattern size was 220 yards (200 m), 0.64% of the total range.
14 out of the 15 landed within 250 yards (230 m) of the center of the pattern and 8 were within 150 yards (140 m).
Shell-to-shell dispersion was 123 yards (112 m), 0.36% of total range.

試験砲撃で右砲のみの射撃とはいえ・・自衛隊が霞む・・
