Radetzky Class Preliminary Project V

The designers decided that the only way to have acceptable secondary firepower (eg at least 6 guns per broadside) and maintain the required main gun firepower of four 30,5cm weapons, was to increase the standard displacement to almost 13.000tons.
Hence the two last designs in the 1904 series were featured increased displacement for two twin 30,5cm and six 19cm Guns per broadside.
