Do we have any better pictures? From that image, it’s hard to tell what is mounted, but in general outline, it does not look much, if any, smaller than the 30mm.Can't really understand why they would downgrade the 30mm to a smaller caliber, it might be a 14.5mm instead of a .50 cal in the same vein as the Russian MPTU HMG.
Maybe, we'll see. The upgrades are similar to what we have seen on other ships, indicating that the fleet is being standardized with these fittings.The upgrades are nice but I wouldn't take it as strong evidence that construction is going to extend beyond 6x units. It all looks like stuff that could be retrofitted to existing ships and that may well be the intention.
I can say for certain that the entire gun would fit snugly into just the 30mm barrel and its housing, the new gun is certainly smaller. Plus the new gun has a carrying handle on the barrel much like the QJG-02 14.5mm HMG. In fact it looks very much like it:Do we have any better pictures?

The 30mm is in a mini-turret, there are additional mounting points for HMG, so it would not make much sense to sacrifice the 30mm for HMGs that they could have mounted in any case.
Additionally, HMGs are typically not mounted unless they are being used, so that makes me question the claim that the 30mm has been replaced.
