The F/CA/1916 design actually has a mixed armament

The F/CA/1916 design has somewhat of a pre-Dreadnought flavor, in that the armament is mixed, although it resembles a more conventional, uniform armament. If the design did not have a secondary armament of 5.5in guns, it would be quite conventional. With the secondary armament, we see shades of the late 19th or early 20th Century (much earlier than 1916). The AA armament has been increased, due to year and the size of the ship. The speed was raised to 31 knots, but the range kept at the rather short 5,400nm at 15 knots. The ships probably would be used on the Atlantic coast and the Mediterranean Sea, so long range is less of an issue. This is the Springsharp report:
