Editing Kirov-class cruiser (section)

===Protection===
The armour scheme formed a raft around the vitals, protected by a waterline [[Belt armor|belt]], [[Deck (ship)|deck]] and traverse [[Bulkhead (partition)|bulkhead]]s uniformly {{convert|50|mm|abbr=on}} in thickness. The [[gun turret|turret]] and [[barbette]] armour was also 50&nbsp;mm thick. The [[conning tower]] sides were {{convert|150|mm|in|abbr=on}} with a 100&nbsp;mm roof. A {{convert|20|mm|in|adj=on}} box protected the steering gear and a number of control positions were protected against splinters: {{convert|14|mm|in|abbr=on}} for the torpedo control station, {{convert|8|mm|in|adj=on}} for main-battery fire control and secondary [[gun shield]]s, {{convert|7|mm|abbr=on}} for the secondary-battery control position and the auxiliary command station had {{convert|25|mm|in|adj=on}} sides and roof.<ref name=y9>Yakubov and Worth, p. 89</ref>

The belt extended {{convert|121|m|ftin|abbr=on}} or 64.5% of the ship's length. Its total height was {{convert|3.4|m|ftin|abbr=on}}, of which {{convert|1.33|m|ftin|abbr=on}} was below the designed waterline. A [[double bottom]] extended past the armored traverse bulkheads and a thin longitudinal bulkhead provided some measure of protection against flooding. It has been judged too thin to withstand a [[torpedo]]'s detonation, but possibly the far-side bulkhead might survive intact, which would cause a [[List (watercraft)|list]] from asymmetrical flooding.<ref name=y9/>

The armor of the Project 26 ships was vulnerable even to [[destroyer]]-class weapons at ranges under {{convert|10|km|mi|abbr=on}} and the last four ships were given additional armor. The belt, traverse bulkheads, barbettes and turret face thicknesses were all increased to {{convert|70|mm|in|abbr=on}} and the box protecting the steering gear was increased to {{convert|30|mm|in|abbr=on}}. One oddity of the later ships' armor scheme was the joint between the armour deck and belt. The top and bottom edges of the belt were tapered, the outer surface angling in {{convert|200|mm|in|abbr=on}} from the edge to a thickness of 45&nbsp;mm. Similarly the deck edge was also tapered down to about 25&nbsp;mm for its outermost 200&nbsp;mm. It has been speculated that "This seam in the protection, representing a small target area, may simply have served to save weight and simplify construction."<ref name=y89>Yakubov and Worth, pp. 89-90</ref>
