This design is not 100% official as it only appears as a pencilled-in sidenote on the revised designs table and the rest is artistic license based on the other designs in the series. Worthy to note that this ship had 13 – 18″ guns and with it it is the most powerful of the series.  For convenience I’ve included both parts of the revised designs table that show the modifications done to previous designs as well (note especially ‘D’ with different arrangement of turrets and superstructure). COmpare this with the table in ‘M’s  WPP.
