Ship project history: Occurrence of these huge and very fast battlecruisers has been called by success which have achieved Invincible and Inflexible in battle at Falkland islands with a squadron of admiral Spee. "Father" of Dreadnought admiral Fisher, having held in 1914 a post of the first Lord of Admiralty, has insisted on building of the 30kts ships armed with 15`` artillery. The price for these requirements was very weak protection, though and slightly improved by a successful design of underwater protection. Results of Jutland have forced to reconsider sights on battlecruiser, and just completed Renown and Repulse were set to refitting and reconstruction.

Protection:  Main 152mm belt was only 2.74m in height, reached between barbettes "A" and "Y". Lower edge of the belt based on the upper part of bulge, incorporating with slope of main deck. Fwd from the citadel the belt was 102mm, terminating approximately in 10m from stem by 102mm bulkhead. Aft from the citadel the main belt was 76mm, closed by 76mm bulkhead in 4m from stern. Upper belt had 38mm thickness. Funnel uptakes over forecastle deck were protected by 38 - 25mm plates.

    Within the limits of citadel the main deck had thickness of only 25mm (already during construction its thickness over magazines had increased up to 51mm); slopes have been constructed from 51mm plates (fwd from barbette "A" and up to fore bulkhead the main deck had no slopes and was flat). Forecastle deck had thickness from 19 up to 31mm amidships. 

    The design of the hull contained a number of the innovations, to most interesting of which began advanced underwater protection, appreciably distinguished from used earlier. In this design "integrated" into a hull bulges for the first time have appeared. The maximal bulges width was 4.3m.

Modernizations: late 1916 - early 1917, both: increasing of main deck thickness up to 76mm over engine rooms (with 102mm slopes); additional plating at lower deck level, up to 89mm over steering gear and 51mm over magazines.

Autumn 1917, Repulse; Early 1918, Renown: + flying-off platforms on turrets "B" & "Y".

(Portsmouth DYd, 12/1918 - 1/1921), Repulse: 152mm main belt changed by 229mm one, thickness of upper belt rose up to 152mm, additional 102mm bulkhead was mounted abreast barbette "Y", main deck thickness over magazines rose up to 76mm with 102mm slopes. Additional external bulges made 30.8m beam, maximal draught rose to 9.60m; + 4 x 2 - 533 TT; full displacement: 37490 t.

9/1921, Renown: - 1 x 3 - 102/45.

11/1924, Repulse: - 2 x 1 - 102/45, 2 x 1 - 76/45; + 4 x 1 - 102/45 QF MkV HA

(5/1923 - 8/1926) Renown: new main belt was 3.65m in height, its thickness decreased to 51mm at lower edge. Main deck and its slopes were 102mm. New 38mm plates were added over boilers between slopes and funnel uptakes.  Additional plates were applied over slopes (102mm over magazines and 63mm over machinery). Additional external bulges were fitted; - 2 x 1 - 102/45, 2 x 1 - 76/45; + 4 x 1 - 102/45 QF Mk V HA, 1 x 3 - 102/45 BL Mk IX.

Aft from the citadel the main belt was 76mm, closed by 76mm bulkhead in 4m from stern. Upper belt had 38mm thickness. Funnel uptakes over forecastle deck were protected by 38 - 25mm plates.

    Within the limits of citadel the main deck had thickness of only 25mm (76mm over turbines and 102mm over magazines); slopes have been constructed from 51mm plates (102mm over turbines and magazines) (fwd from barbette "A" and up to fore bulkhead the main deck had no slopes and was flat). New 38mm plates were added over boilers between slopes and funnel uptakes at main deck level.  Additional plates were applied over slopes (102mm over magazines and 63mm over machinery), increasing main deck area. Forecastle deck had thickness from 19 up to 31mm amidships. Lower deck over steering gear was 89mm and over magazines was 51mm thick.
