Where Russian dreadnoughts fit internationally

Which British dreadnoughts best compare with the Gangut, Imperatritsa Mariya, and Imperator Nikolai I classes?

Early 12-inch British dreadnoughts are the nearest match, with Dante Alighieri another useful comparison, not the later 13.5- or 15-inch ships.

The closest British comparison is HMS Dreadnought and the other early 12-inch-gun classes. Once the Royal Navy moves to 13.5-inch and then 15-inch weapons, the comparison becomes much less useful. Italy's Dante Alighieri is another close international contemporary. These comparisons place the Russian ships by design generation and capability rather than treating every prewar dreadnought as equivalent.
