How could the iron-hulled battleships, build on industry, that simply didn't exist less a decade ago be NOT experimental? Where they could find the experienced construction crews for this project? You missed my point; they are experimental in the meaning of experience for constructors and engineers, that NEVER BUILD SOMETHING LIKE THAT BEFORE.



They are not "experimental" --- in the sense in which you appear to be using the word --- at all. They are incremental, building on the basis of the experience gained in building the initial ironclad conversions followed by the first class of purpose-designed river ironclads, followed by the first class of coastal ironclads. The initial design work is experimental, but with the proviso that the chief designer is a member of the inner circle and in a position to intervene in anything which threatens to go too far off the rails.

The construction personnel building these ships have acquired a very impressive resume in previous construction projects, and they will gain more in the course of building them. And, yes, there will be instances in the building process of problems which bite people on the butt because of inexperience in the yards, but they still aren't "experimental" and they still don't constitute being "experimental in the meaning of experience for constructors and engineers, that NEVER BUILD SOMETHING LIKE THAT BEFORE," given the Delthak IIs and Eraystors (which I have repeatedly told you are coming) classes which preceded them, unless you want to argue that building the 1905 Dreadnought required the evolution of "experimental" technologies and construction techniques rather than a new and more powerful combination of existing technologies and construction techniques. And before you point at her turbine power plant, allow me to point out that (a) civilian turbine use was already a reality (you do remember Turbina and the Naval Review at Victoria's Diamond Jubilee?) and (b) that Dreadnought would have been equally revolutionary with triple-expansion engines and an 18-knot tope speed. The high (relatively speaking) speed was icing on the cake and, in fact, represented what was in many ways an unnecessary complication.

I would argue that aside from the Dreadnought's 2,000-ton displacement advantage (which bought her a higher freeboard and raised the axis of her main battery guns and nominal endurance advantage (6,600 nautical miles versus 5,100), USS South Carolina, with reciprocating engines, was actually the superior design. She gave the same broadside weight and equal or superior standards of armor on that same 2,000 less tons, at the cost of a somewhat greater tendency to roll in heavy weather because of the increased weight of the superimposed turrets high up in the ship (relatively speaking). I would count her inherent combat advantage in terms of broadside firepower per ton/unit and ability to carry matching armor on her lower displacement as more decisive than the Dreadnought's theoretical 2.5-knot speed advantage. It was primarily the difference in building times (and the very different levels of urgency their respective nations attached to naval construction) which permitted the British designers to build larger numbers of ships at each stage of the forward bounds in dreadnought design evolution and permitted the Royal Navy to stay in front of the USN. I personally would have backed the Pennsylvania over the Iron Duke and the Colorado over the Revenge and even the Queen Elizabeth in a stand up fight, despite the Brits' nominal speed advantages, and there were quite a few British officers who would have agreed with me. And, in fact, who did agree with me (in writing) at the time.

The other point is that the designers have access to the experimental work of at least 500 years of Terran steam engineering, they just lack the technological base to manufacture the final bleeding edge designs. The experimental side of these ships is not in the design, it is in the construction. The builders will never have performed the tasks they are being asked to do and will be learning on the job.
I would expect a significant fatality and injury rate during construction under these conditions based on real world events. (There is a reason construction sites have gotten safer over the last 50 years and I doubt that a) they have site safety officers or b) if they do they are members of the inner circle).
Even a basic industrial training organization needs to be built (a typical third world error, you build a university and not a trade school, so you have masses of engineers and no tradesmen or technicians (the soviet union also made this mistake in the cold war, so you get cutting edge design and a kludge in the execution and poor maintenance)).

Another thing to note is how long those guns are:

Armament:
4 10”/40 (2 x 2 centerline with shields)
10 8”/40 (10 x 1 in casemates)
8 4”/45 (8 x 1 with shields)

The second number after the '/' is the number calibers in the length of the gun tube IE (a 10”/40 gun tube is 40 x 10 inches x 1 foot / 12 inches =) 33.33 feet or 9.8 meters long the breach should add about another meter. A 8"/40 I'll do math in metric for you 8" x 40 x 24.5mm/" 1m/1000mm = 7.84 m again you have to add the breach. A 4"/45 is 4" x 45 x 24.5mm/1" x 1m/100mm = 4.41m.

As a Wild Assed Guess (WAG) the breach is 5 calibers long, so same type math above yea1s 10" = 1.225m, 8" = 0.98 m, and 4" = 0.49 M

Adding gives total gun length 10"/40 = 11.025m, 8"/40 = 8.82m, and 4"/45 = 4.9m

Hope this helps, to me your guns are too short, or RFC's are too long ;)

Colleague, i know it perfectly. The problem is always - what part of the gun barrel is INSIDE the turret or casemate? ;)

I've got nothing to say on the technical details, and their rightness or wrongness, but I would like to thank you for taking the time to do that illustration.

Seeing it gave me a real 'aaaaah' feeling - and a much clearer impression of how mind blowing the KGH's would be/will be to the NOG/AOG people, even to any that, by some v odd coincidence, happened to have actually seen the Great Canal raid boats.

Just out of interest, roughly how long would one of the galleons be by comparison - half the length?

I grew up in Pocatello, Idaho and at age six visited the Naval Ordnance plant there, Imagine a sixteen inch naval rifle between centers, the operator riding the tool carriage as the huge gun turns at 1-3 RPM. The tool bit was two inches square, 50mm. They used water to keep the liner cold while heating the exterior to remove a worn lining, OH the steam!

We discussed this plant and someone posted a photo of a 16" gun on its mount. As a WAG about a tenth of the length would be behind the splinter shield. Here's a link to a 4"/50 showing mount, splinter shield removed but about where that bar on top of the gun sits, this particular gun fired the first shot of the USA in WW II on the USS Ward at Pearl Harbor.

Thank you!

Well, the real galleons was about 30 to 50 meters between perpendiculars. So... the KH would be more than three times bigger than the average, and more than twice bigger than the biggest. ;) For the sail-level navy... it would be a psychological shock of inprecedent level; enought for even the Church crews to just ran the ship around and run away.

Found this cut away drawing of a 16" turret on Iowa Class BBs that shows how little of the length in in the turret or behind the splinter shield http://en.wikipedia.org/wiki/16%22/50_caliber_Mark_7_gun#mediaviewer/File:Iowa_16_inch_Gun-EN.svg you can look at lager view and it's a good render Using the old hash marks on paper method looks like a third of the gun is in the turret, and two thirds outside :D Note the shock absorbing cylinders that allow gun to recoil are top mounted so gun can be raised to a high angle after loading by lowering the breach.

Poker, I don't think he's far out at all on the indicated barrel lengths. Maybe a little, but not much. I'm using the standard US practice in which the barrel length includes the breech. Therefore a 10" 40 cal is 400 inches (33' 4") including breech, and it looks to me like (allowing for the portion behind the shield) he's about right on that. Hard to tell from the image on my laptop, but overall, pretty darned close, I'd say.
