Armored belt and four barbette turrets. Ram bow and overhanging dome stern. The armor-belt covers the water-line to the height of the main-deck beams, coming below the point of the ram and covering the steering-gear. The barbette turrets are arranged one on each side, abreast the forward smoke-stack, having an overhang of nearly half its diameter, so as to give clear fore-and-aft fire. The other two turrets are amidships, before and abaft the mizzen-mast. There are two armored pilot-houses on the Duperré, one abreast the forward turrets and one between the after ones; the Duguesclin has but one, forward. The gun-deck battery is composed of light rifled guns, unprotected. The deck plating of these ships is three inches in thickness (one inch steel over two inches of iron). A bow-gun works in a single port under the topgallant forecastle.
AMIRAL DUPERRÉ.
DEVASTATION. FOUDROYANT. REDOUBTABLE.
Armored belt and redoubt. Ram bow and dome stern. The belt of the Redoubtable encircles the water-line to the height of the main-deck beams, curving down forward over the point of the ram; that of the other two ships stops short of the curve of the counter in an armored bulkhead, the lower edge being carried on by an armored deck to protect the steering-gear. The sides forward and abaft the redoubt are given a rank tumble home, the redoubt rising straight to the spar-deck, thus giving clear fore-and-aft and beam fire from the main-deck battery. A heavy gun is mounted in barbette on top of the redoubt, each side, having a clear firing angle of 180°; the gun-slide alone is protected by armor, while a musket-proof shield is mounted on the forward part of the slide, as protection to the crew. On the spar-deck is carried a battery of light rifles in broadside.
