Mind you said belts on the French Dreadnoughts were not very thickI wouldn't be too hard on the Brits for this, this was very common with incremental schemes of the era. Germany didn't install that sort of full-length belt until the Konig and Moltke classes. The US didn't do it between South Carolina and Nevada. The Russians did on the Ganguts but not the Imperatritsa Mariyas. The British didn't do it until the Iron Dukes, and even then that comes with the asterisk of only going to the halfway mark at the end barbettes, which is also what the Austrians did on the Tegetthoffs. Only the French had a full-length belt on all their dreadnought designs of the era, one of the few places where they were ahead of the game.
