Clarke challenges accounts that give G3 the same 16-inch guns as Nelson. The book page he has available specifies 16.5-inch guns, while he traces the conflicting identification principally to John Campbell's work. His interpretation places British development after the 15-inch gun around 16.5-inch and 18-inch alternatives and attributes the later 16-inch choice to treaty limits. He checks the cited references during the exchange but does not resolve the disagreement.

Disputed accounts of G3's intended guns
Conflicting descriptions identify G3's planned armament as either 16.5-inch weapons or guns associated with the later Nelson class.
