It’s funny that you mention it, since single land mounts should have far better dispersion than naval mounts as a result of eliminating factors. You wouldn’t have to deal with the constant rolling of the ship on the sea and the after effects of gun recoil due be being mounted on land. A single mount would ensure zero blast interference from other barrels.
You can see the dispersion from large caliber single land test mounts in this report from the
US Naval Weapons Laboratory here: Naval Gunfire Dispersion
Most notably, the results of the Mk 7 16"/50 mount firing an AP shell estimates a spread of less than 100 yards at a whopping range of 42,345 yards!
Whatever the case may be, it would be very hard to argue that a triple naval mount could match the dispersion values of an experimental single land mount.
Keel breaking is also conveniently not modeled in war thunder though.
I’d be curious about the performance of AShMs that use SAP warheads and use a terminal attack profile that pops up from sea skimming to attack the enemy target from the top downward are against battleships. It’s obvious the extremely large Soviet AShMs will deal significant damage to anything they hit, even a battleship; but what about a volley of Harpoons or Exocets? Who knows.
Offtopic but the fact they’re giving them bukm3 instead of something worse is insane. Pantsir is already second best spaa with the best survivability and fastest missiles. Give them some lower tier multi spaa to add some flavour.
