The Caernarvon’s original final turret (now stock turret) is said to be underwhelming. Due to this, WarGaming gave it the Action X’s turret a few patches ago. However, it may change soon. Aleksander Galevskyi, a lead artist at WarGaming, posted quite a bit of screenshots of a Caernarvon with a peculiar turret which I originally thought was the stock Caernarvon turret without its mantlet. I’ve been told if the new turret is modelled correctly, nothing will be able to penetrate it. If it’s true, it’s possible that this is a historical replacement for the unhistorical Action X turret featured as the final turret on the Caernarvon. We may expect a buffed Caernarvon in 9.18 or in later iterations. Alternatively, it could be another premium.
Update: the mantlet is said to be over a foot thick in real life. However, the surrounding remains the same as the stock Caernarvon.
Here are the screenshots…
