The 8" column covers everything below. 204mm is the next step.

Ok now I am really confused.
If 8" covers everything below, then the answer to my original question

QuoteSo- will the 7"/180mm "count"  for the 8" class, so the next gun can be 10" ?
Or do I really need to research a 210mm gun also.

Was yes for the 180, but 210 would have been to large and I can't have just researched it. 

But if 8" covers everything below, my 1905 105mms count for that column, in which case I can move two spaces...to the 10" gun.

SO...
What are the required research hoops I must jump through to get from 105mm naval gun (ignoring the larger army guns) to a 10"  railroad gun?

Having the relevant Railgun techlevel is enough.

Then it's just a question to develop the gun in the suitable size, and then your maw size is dependent on the techlevel of main gun size you have, with 10" as obsolete, it ain't a big jump to a 10" railgun.

Quote1900: Baseline (0): Railway guns of up to 150mm, armored trains
1905: Advanced (+1): Railway guns of up to 254mm
1910: Cutting Edge (+3): Railway guns of up to 356mm
1915: Futuristic (+5): Unrestricted calibre railway guns

In my case I only have the 1905 Railgun and 1905 Naval artillery techs. There was an objection to my simply researching a 10" gun.

Bavaria would appear to have only two naval guns in use - 1906 105mm and 88mms. This presumes the 210mm coast artillery at Trieste was Austrian.

I want to develop a 10" gun that I can use for a railgun, or perhaps at some point an AC's main guns.

There was an objection to presuming there was already a Bavarian gun in the 8-9" range allowing the research on the 10".

As such I could not simply develop the 10" gun without first developing a weapon in the 8" class. 

Inquiries as to if a 180mm weapon would count as that 8" class seemed to yield a "no" answer. 

Rocky's earlier answer and P3Ds last answer would seem to indicate it might indeed.

So I'm back to trying to get it explained to me in simple language because the answers I am getting do not seem to mesh overly well, hence my confusion.


The basic question is n order to research a 10"/45 or 10"/50 naval/railroad gun, what gun sizes do I need to research previously? 
From the chart, the answer is an 8"/45, an 8"/50, or a 9-9.5"/ 40-50.
OK, so how do I get there from my 105mm weapons?

1. When you start research on the Naval Gun Technologies chart, does your first weapon have to be an 1885 8"/40, or can you start with a caliber commiserate with your tech level, in this case an 1905 8"/50 ?

2. That 8" gun category includes : bore size N to 8.0" (203mm),
what is N?  Can N be as low as 180mm ? Can N be as low as 105mm?
If the former, I can build the 180mm gun I want,
if the latter, then I already have a qualifying weapon and could have gone and researched the 10" gun.

Bavaria inherited the relevant Habsburger and French tech, but lacks the industrial capacity to use the knowledge.

So, actualy, it ain't the research that is costing money, but the building/retooling of the factories to build the damn stuff.
 

1905 tech gives the Bavarians  acces to the French 13.5" l45, but not the capacity to build it.

Well, thats a new and entirely different answer.

So I have the blueprints for the French 275mm guns from the 1895 Gloire, and the 240mm of the 1885 Budapest and could build either, but it due to the need to construct suitable facilities, it costs the same as designing a 254mm/50 gun from scratch?

Well thats better than having to do an 8"/40, then 8"/50 then 10"/50 as I was starting to fear.

Not entirely sure I am unconfused though.

My understanding is that the naval gun chart is more for the BB/AC architecture, which is guns 6.5" or larger. Therefore my guess is that 6.5" is the 'n' in your equation. Anything smaller than that still has to be researched, but gun tech level is unimportant per se. My 2 cents, feel free to correct/critique me.
