Editing St Vincent-class battleship (section)

===Armour===
The ''St Vincent''-class ships had a [[waterline]] [[Belt armor|belt]] of [[Krupp cemented armour]] that was {{convert|10|in|0}} thick between the fore and aftmost [[barbette]]s that reduced to {{convert|2|in|0}} before it reached the ships' ends. It covered the side of the [[hull (watercraft)|hull]] from the middle [[deck (ship)|deck]] down to {{convert|4|ft|11|in|m|1}} below the waterline where it thinned to {{convert|8|in|0|}} [[amidships]]. Above this was a [[strake]] of 8-inch armour. Transverse [[bulkhead (partition)|bulkheads]] {{convert|5|to|8|in|0}} thick terminated the thickest parts of the waterline and upper armour belts once they reached the outer portions of the endmost barbettes. The three centreline barbettes were protected by armour {{convert|9|in|0}} thick above the main deck and thinned to {{convert|5|in|0}} below it. The wing barbettes were similar except that they had 10 inches of armour on their outer faces. The gun turrets had {{convert|11|in|0|adj=on}} faces and sides with 3-inch roofs.<ref>[[#Burt|Burt (1986)]], pp. 76, 78.</ref>

The three armoured decks ranged in thickness from {{convert|0.75|to|3|in}} with the greatest thickness outside the central [[armoured citadel]]. The front and sides of the forward [[conning tower]] were protected by 11-inch plates, although the rear and roof were 8 inches and 3 inches thick respectively. The aft conning tower had 8-inch sides and a 3-inch roof. The ''St Vincent''s had two longitudinal anti-[[torpedo bulkhead]]s {{convert|1|–|3|in}} thick that extended from the forward end of 'A' barbette to the end of 'Y' [[magazine (artillery)|magazine]]. In the vicinity of the [[boiler room (ship)|boiler rooms]], the compartments between them were used as [[coal bunker]]s.<ref>[[#Burt|Burt (1986)]], pp. 78, 80.</ref>
