World of Tanks Supertest 9.21: Caernarvon Action X Details

2 min read

Caernarvon Action X was a further development of the vehicles designed by the English Electric company under the “universal tank” concept (FV200). Ther project was discontinued in favorof the A41 tank (Centurion). No prototypes were build.

There aren’t any details if this tank will be a Premium or Reward tank yet, but I strongly believe this will be the first Tier VIII Premium heavy tank released for the British branch.

  1. The possibility of one of the new premiums being a reward tank could be reasonable, since it’s been a while since the last tier-8-premium-mission-marathon, but what are the odds of them running a marathon through the xmas holidays?

  2. Rather then a clone of the old Caernarvon, it would be nice if they gave it a 105mm, to better differentiate between it and the current one

  3. With spaced armor plates on the turret…

    See, this is why I suggested it should have a 105mm gun… Where’s the power creep at with this tank?

  4. I think DPM calculation is wrong. If it fires 10.605 rounds per minute than it should have 2439 dpm.

    All in all it looks like a strick upgrade over old Caernarvon, almost 2 second better reload, better turret and more mobility for having slightly worse gunhandling makes this a nice tier 8 tank.
