The front and sides of the forward conning tower were {{convert|10|in|mm|0|abbr=on}} thick while its rear was {{convert|7|in|mm|0|abbr=on}}. The walls of the rear conning tower were six inches thick. The roof and floor of both conning towers were KNC armour 2 inches thick while their communication tubes were {{convert|3|in|mm|0|abbr=on}} of KNC. The signal tower immediately aft of the forward conning tower also had three inches of KNC. [[

===Aircraft===
By 1918 the two surviving ''Invincible''s carried a [[Sopwith Pup]] and a [[Sopwith 1½ Strutter]] on flying-off ramps fitted on top of 'P' and 'Q' turrets.<ref name=c24/> Each platform had a canvas hangar to protect the aircraft during inclement weather.<ref>Roberts, p. 92</ref>

==Construction==
The three ''Invincible''s were ordered at the same time as ''Dreadnought'' as part of the 1905–06 Naval Programme. The following table gives the build details and purchase cost of the members of the ''Invincible'' class. Whilst standard British practice at that time was for these costs to '''exclude''' armament and stores, for some reason the cost quoted in [[Brassey's Naval Annual|The Naval Annual]] for this class ''includes'' armament.
