Removing a triple turret and replacing the machinery raised Giulio Cesare from 21 to 27 knots. Under the working classification used here, she remains outside the fast-battleship category because its boundary begins at 28 knots. The line is acknowledged as arbitrary, with Yamato presenting the same classification problem at roughly 27 knots. Historians still need consistent boundaries even when technical performance changes continuously instead of fitting neat categories.

Why 27 knots still falls short of fast-battleship status
Giulio Cesare's 27-knot reconstruction sits just below the conventional 28-knot boundary used to distinguish fast battleships.
