Key Features:
  • Medium-close range brawlers with short firing ranges, torpedoes with high damage but small launch sectors, secondary guns with a high chance to set fires, as well as quick acceleration and manoeuvrability characteristics. At the same time, they would have average accuracy and HE penetration values. The deck armor is the same as that of British heavy cruisers. Available consumables would include Engine Boost, Defensive AA Fire, and Repair Party.
  • Long-range ships with high accuracy and powerful HE and AP shells. Equipped with Engine Boost, Defensive AA Fire and a standard Repair Party. They would however not have improved manoeuvrability and powerful armor.

  1. I was afraid of this when I saw the 836 m/s velocity for the main guns in the devblog for when the British battlecruisers were announced because that's the same velocity as Monarch's guns. Lo and behold, of course it seems like they are giving the J3 design the wrong guns (just like Kansas (South Dakota (1920)-class battleship) and Constellation (Lexington-class battlecruiser)) for whatever reason. The whole point of J3 was that she was the K3 design with improvements and had the 3x3 18-inch/45-cal main battery reduced to 3x3 15-inch/50-cal main battery to save almost 100,000 tons. She's essentially an improved Hood with slightly better armor, much bigger, faster and had essentially the most powerful type of 15-inch gun the Royal Navy would ever design in a layout extremely reminiscent of a Littorio-class battleship. But, sure, Wargaming, let's give her Monarch's 15-inch/45 Mark II guns (erroneously designated in-game as the Mark VII gun, despite there was nowhere near that much 15-inch gun designs, only the WW1 42-caliber gun, the 50-caliber one for the J3 design, the 45-cal 15-inch gun proposal (15C) of the KGVs, and the all-forward 2x4 15-inch/45-cal design (1945 X3a) of the Lion-class battleships). Oh, yeah, and let's give it 31.9 knots (marginally slower than Hood) instead of 33 knots. Because, why not.
