Build a modern battleship

We are seeing in real conflict that aircraft is so much cheaper than tube artillery that it is affordable to dispose of the airframe for every round fired, even for mission within range of a compact fiber optics spool.
It's not that simple. Someone make a cost comparison table.
The thing going for aircraft is speed and arguably range. But range is consumed by the distance of the homebase airport. So this does not apply generally to all aircrafts.
Typical allied/coalition/NATO operation involves a hundred aircrafts for one or two strike flights. From what I see it's been the same since the Vietnam war.
A towed/selpropelled cannon can act on their own.
Even if we ignore the airport/base cost the aircraft still needs a runway and a shelter, and tankers (car).
A proper cost comparision has to be widen to a force size level rather than a single system.
 
It circles back around, naval firepower is about striking in a time sensitive window at level of force that is unable to be carried out by other means. Tube artillery can cover a much greater volume at a sustained and measureable quantity. Aircraft are best for hitting targets of opportunity. Aircraft sorties will always have greater costs.
 
A technological environment where it is plausible for a battleship to shoot down every flying projectile at it is one where it is possible for a fortress to shoot down everything the battleship is shooting at it. (and sink the battleship with long range torpedoes, to use another threat vector) The battleship is even choosing a weapon with low rate of fire while those shooting at the battleship would logically choose munitions with greatest defense penetration capability.
Yeah, but battleship have one advantage there; it's mobile, and several of them could concentrate to oversaturate the fortress defenses. The fortress cannot move; it's defenses and attack capabilities are the fixed parameter. It could be overwhelmed with enough battleships to oversaturate defenses and knock them down.

P.S. Why autoloading cannons are weapon with low rate of fire?

Ground forces are mobile and better still, can be practically concealed to ambush ships.

Fortresses are default because earthworks is cheap compared to the mobile elements.

Cannon barrels have to handle a lot of energy and is a bottleneck. Rocketry and other self-propelled munitions have no such bottleneck.

A strike package that needs to self escort to hit thousands of kilometers behind the enemy front is a different issue than a force covering artillery range.

Even backpack FPVs can now cover conventional tube artillery ranges, and logistics support for aircraft up to exotic artillery designs still fits in a normal van.

Increasing maturity of stuff like tail sitting VTOL turbojets really change the support requirement to vehicle performance equation.

It circles back around, naval firepower is about striking in a time sensitive window at level of force that is unable to be carried out by other means.
People talk about the time sensitive window because bombs are cheaper than shells and price is not the main talking point. The advantage of artillery is persistent readiness unlike airplanes with limited time on station.

Which is likely useful in an amphib situation, but not that useful if you just want utter tonnage on target.
 
Maybe you can rephrase some of that to fix the broken logic. Bombs are not cheaper than shells in most circumstances. If you can reach it by gun its getting used for delivery. Like a cargoship carrying goods, there is no cheaper delivery service than tube launched per ton of pyrotechniks.

Big tubes? I think some of it is the sheer size that the shells are, and the sheer size of the required loading gear. That stuff can't move quickly, at least not safely.

5" guns seem to max out at about 40rpm. But 6"/155mm guns seem to be more like 12-15rpm, and 8" guns are 10rpm at best.

Well, I assumed guns of no more than 6-8 inches for "modern battleship"; autoloading, in large enough numbers to provide a saturation attacks.

P.S. There is another advantage battleship have over fortress. The battleship could "blind-fire" against fortress using only coordinates to precisely hit defenses. Fortress need to track battleship in real time.
 
Consider: Russia fired the entire stockpile of decades as 2nd strongest military power worth of shells in Ukraine, and it didn't have decisive effects. Ultimately both sides run short of artillery shells and have to hold the front with drones as primary fires.

Consider: Pacific islands were completely encircled by battleships, but still could not be taken without grueling close combat.

The lesson since ww1 is that dumb artillery is destructive against exposed targets, however hard cover massively reduce effectiveness down and one needs dora scaled pieces to defeat tunneling. Tube artillery just doesn't do much without a ground element applying pressure at the same time.

The 8" Mk 71 could do 12rpm; fastest trial was 12.6rpm or 4.76 seconds between rounds. I suspect the lower RoF of the AGS (10 rpm) was due for reliability, could also be due to limitations from the fact its launching LRLAP that are much larger than normal 155mm shells.

Very large-calibre fully automatic guns are an unknown quantity since none IRL were built. The Alaska-class' 12"/50 Mk 8 achieved its ~3rpm RoF due to having two-stage hoists compared to the single-stage ones on BBs; the British Mk IV 16"/45 proposed for the various post 1939 Lion battleship designs allegedly were to have single-stroke ramming of the whole projectile/propellant assembly to get an RoF of 3rpm. I suppose, just by the sheer size of the projectiles and propellants even with all the post-WWII developments, a notional automatic very-large calibre gun that combines single-stage loading and proper hoist design of 12-16" would probably be reliably set for 3rpm, with 4rpm probably possible but then you're gambling with things like hoist reliability and safety.

Interesting. That makes the 6"/47 DPs relatively slow for their shell size, if 8" can get up to 12rpm. Admittedly, I think that's with a design taking advantage of the fact that the single barrel put the breech roughly on the center of rotation of the turret. A multiple gun turret would probably make that a lot more challenging.

The British 6"/50 QF Mk N5 could hit 20rpm, though at that RoF barrel heat and reliability became issues, with 15-17rpm being considered the RoF for best reliability.

I think the 6"/47DP Mk 16 twin mount was just not an optimized design and was not given time to mature, evident in its service record relative to the Des Moines' 8"/55RF Mk 16 or even the British QF Mk N5. IIRC there were plans for a revised triple mount for the 6"/47DP that would've improved matters, but the end of WWII and the shift to guided missiles ended any plans to produce them.
 
An 8-inch rapidfire gun at 10-12 rounds / minute that can reach 40+ miles would look pretty smart in the Hormuz Strait at the moment. If reports are true we are seizing Kharg Island are true, looks even smarter.

I think it is deliberately obtuse of you to refer to Mavics as an air force. If you want to go that route, then you need to use much more clear language about when you mean "air force" as in large platforms capable of carrying SDBs at least, or "air force" as in small platforms with a sub-50km range and <40lb payload.
Bombs is the lowest cost explosive payload, nothing else comes close. Glide bombs comes close and its ranges can exceed artillery.

Airframe costs was high only because a (expensively trained) human is involved. Without the human, the airframe can be scaled to fit the mission, and it is known that it can cover the artillery range case while still being cheaper.
Large strike-capable drones still cost tens of millions of dollars, it isn't the pilot driving up the cost.

If you're again referring to COTS octocopters, are you suggesting that a battleship festooned with Baba Yaga drones would be more capable of destructive fires than with a 16" gun armament? Because that is an absurd statement, and I can elaborate why if you are being serious.
Artillery in practice depends on concealment, dispersion and deception to survive. There is the theory of using active defenses however offense have been consistently cheaper than defenses and anywhere remotely similar investment in aircraft defenses or redundancies result in greater survivability.
My friend. Everything relies on concealment, dispersion, and deception to survive. Develop this point better. Why is it different for gun systems compared to aircraft? Why is that difference favorable to your case?
A technologicalenvironment where it is plausible for a battleship to shoot down every flying projectile at it is one where it is possible for a fortress to shoot down everything the battleship is shooting at it. (and sink the battleship with long range torpedoes, to use another threat vector) The battleship is even choosing a weapon with low rate of fire while those shooting at the battleship would logically choose munitions with greatest defense penetration capability.
Knock it off. Stick to a more narrowly defined hypothetical, because this sweeping statement is absurd.

I am suggesting that carrier-based fighters, backstopped by SM-6, ESSM, and SeaRAM, could allow a gun-armed battleship group to approach to ~100 kilometers distance from a target. By evading detection through practices that will be standard in this type of warfare, they will not face a deliberate attack, only a hasty attack--insufficient missiles for a proper saturation of air defenses. The battleship group can likely defend itself from a few dozen missiles at once, a couple of times, which they should only expect to receive after shedding discretion and firing on the enemy.

The enemy "fortress" will not face a few dozen missiles, it will face a sustained barrage of hundreds or thousands of shells. The shells won't be impossible to intercept, but interceptors will run out. The interceptors would run out if the fortress was under missile attack, as well, because the attacker has the initiative and wouldn't plan an attack that failed to saturate. The difference is, 600 Tomahawks to saturate defenses costs a billion dollars and uses up 20% of stockpiles. A saturation with 16" shells costs MAYBE 10% as much and correspondingly would not deplete stockpiles so severely.

The generalization "if the battleship can defend itself, so can the target" is ridiculous and untrue, and logically, could also be applied to systems you DO like. If carrier aviation can strike from 500 miles, well obviously, so can enemy aviation. If the carrier bomber can get through, can't the enemy? I don't think this is a good basis for an argument.

There really is no need. We have an enormous natural experiment in front of us. Every military in the world has an artillery park; the big and rich ones have an air force.
Consider: Russia fired the entire stockpile of decades as 2nd strongest military power worth of shells in Ukraine, and it didn't have decisive effects. Ultimately both sides run short of artillery shells and have to hold the front with drones as primary fires.
Again, I have to ask. Are you claiming that a drone-carrying warship would have a greater effect on target than a gun-armed warship? And to be clear, when I say drone, I'm talking about Mavics or maybe Vampire drones, not Reapers.
Consider: Pacific islands were completely encircled by battleships, but still could not be taken without grueling close combat.
Terrible point. Pacific islands were also encircled by carriers, and the carrier aviation also failed to seize the islands without grueling close combat. Is carrier aviation pointless as well then?

This is entirely valid, but also true of aircraft. The point is that fires on their own don't win wars. We aren't arguing that. What is a more efficient way to wipe out enemy infrastructure? Expensive cruise/ballistic missiles, expensive airframes firing expensive cruise/ballistic missiles, expensive battleships firing cheap shells?
 
Against fixed targets you could get by pretty well without the full sensor suite of a GL-SDB. Laser gyro INS, bolstered with less sophisticated terminal homing, and mid-course corrections would be pretty difficult to defend any fortified target from saturation attacks. I still like the idea of sustainer motors and fold out wings. One ship would overwhelm a cluster of SAM batteries. INS is resistant to any jamming, and modern midcourse datalinks are pretty resistant to detection let alone interuptions. I still like the idea of a big gun getting these kinds of projectiles up to a cruising altitude inline with the previous VGAS concepts. Iran couldn't cluster their speedboats in marinas like they've been doing if they were within reach of big guns like that. Would much prefer a 500km capability as the target but even a 180 km reach would score a lot of clout in a Hormuz Strait or Red Sea situation.
