The drone factors strength is cost and saturation.

While smart ammunition is proven, it’s pricy to the point of being prohibitive.
Army is going long range with rocket solutions big and small.
Small is artillery sized effect.

To me the 5' still has a place.
Not every threat is a drone, I would take the increased range when it comes to ASMs.
Most drones would not require the use of smart ammunition, so while there is still a price factor it is not insurmountable.
I am also looking at possible future developments such as HVPs, Kingfisher rounds and cannon launched loitering munitions.

Just going off ye olde Wikipedia:

Mk45 weighs around 22,000kg
Mk41 (8 cell) weighs between 12,200kg and 15,000kg depending on length + missiles (280kg per ESSM so probably around another 9,000kg, give or take).

Is the gun worth 8 cells? Plus the engineering work and costs to remove and replace it? I guess that's up to the navy. I'm betting navy says yes.

EDIT: Reading that back, I could have been more clear. I meant the cost of removing the gun, in exchange for 8 cells, is probably not worthwhile.

8 cells quad packed with ESSM means 32 rounds. How many rounds does the magazine for the Mark 45 hold? In a lengthy engagement you could stay in the fight for quite a while with the gun. The missile load could be expended in minutes.

Depends a little bit on which vessel has the Mk 45 and possibly which Mod it has. The USN's Arleigh Burke-class DDG's have 680 rounds for their Mk 45, whilst the Ticonderoga-class CG's would usually run ~600 rounds. No idea what some of the other classes fitted with Mk 45 would run, but clearly the capacity is likely in the hundreds of rounds.

The 76 mm and 57 mm guns having varying amounts of stowed ammunition which is highly dependent on which specific gun/mounting is used. Given that a number of the mountings for at least the 57 mm gun are non-deck penetrating, a 5" gun will likely have more ammunition aboard ship and be able to stay in the fight for a longer period of time unless a magazine gets fitted somewhere else.

Thanks for that.
