G3 is described as a 46,500-ton design with about 160,000 shaft horsepower and a projected top speed around 32 or 33 knots. The one-knot uncertainty matters because an unbuilt ship has no exact trial result. Ark Royal and the Nelson class provide Royal Navy examples whose realized or demonstrated speed could exceed a simple headline figure. That experience makes a little extra performance plausible without turning the estimate into a certainty. A range of roughly 7,000 nautical miles at 16 knots would also give G3 operational reach as well as tactical speed.

G3 speed, range, and uncertain performance margins
Projected displacement, horsepower, speed, and cruising range are paired with a warning that Royal Navy ships sometimes exceeded their conservative official figures.
