Thanks Jefgte !

So that's why I built that as a spreadsheet.
You can plug Jefgte's offerings in and see how the numbers work, just as you want.
He's got very nice AC designs. That VDT layout is a contender if you want to save a little tonnage.
Alternately, you could drop my version and the Norse ship, and see how many of Jefgte's you can fit in.

Your nation :)

The answer is...the # of TTs should be listed at the very bottom of the write up.
There is a springsharp tab for them, but it does not have the right tonnage.
So we set aside 'miscellaneous weight' and make notes at the bottom.

Thanks... but I squint and I squint, and I can't see the TTs for that. That goes for most sheets, I can't tell if the TBs I just accepted have 4 or 5 TTs.
THat's a little annoying because Torpedoes are a major item for this class.
What does that one have, and where do I look?

Ya, its under the Misc weight alocation. Apparently I didnt add that to this springsharp file. Should be 12x530mm tubes in 4 tripple launchers (two per side) ala Clemsons. Add some weight for FC and thats about all the allocation can suport.

EDIT: Modified from the Roman F-Class

I think I could use one of those, but not the BB.
It is coming hot & heavy today, but I need to break. I'll be back in a couple of hours.

If you download the spreadsheet, the "cost" column simply multiplies #suggested by tonnage.   
The "Tonnage remaining" simply deducts all the numbers in the "Cost" column from the budget.

So you can change the #suggested up and down to try different combos.
You can also add ships that folks post in the next lines down and see how they fit into the Fleet "Mix"
So you can customize to your desire.

The Rock Doctor

I'm not going to pro-actively offer new designs, because I don't want to overwhelm Anchor with too much stuff and I'm not yet clear on what his design priorities are.

However, if he sees a Union design he'd like to request tweaks for, I am totally cool to do that.

Or request a new design based on the various guns listed in my naval artillery thread.

TacCovert4

Same.  I've offered off line help on designing new classes for his new production,  and suggesting some things along those lines.

Okay, I appreciate all the help, but I am starting to hit a wall here, I'll be back tomorrow .... or after I have a look at this spreadsheet.

Ok, so you indicated the Norse Monitor might be a bit more than you were looking for.
So I modified a Parthian gunboat design I had.

The Norse was 2,996 tons, this is 3000, so same budget 'cost'.

This has 180mm guns fore and aft for a fair amount of HE power.
Superimposed over the aft gun is a shielded 118mm Howitzer for arcing shots.
The main belt is +1 /-1 of facehardened armor along the waterline, while a 65mm belt carries to freeboard, rendering the ship fully armored.
at 3.9m, the draft is shallow for inshore work.  Torpedo nets are fitted so it can sit offshore and conduct bombardment safely.

The ship is very beamy, which makes it a steady platform. It also gives it the amidships deckspace to stack ships' boats.
These can be motor launches for marines, or MTBs.  There is room for both Marines, and large numbers of torpedoes or mines.

Ok,

So this is a DRAFT turn sheet for 1913.0.

I broke Ethiopia into 3 regions.
The Northern Kush (Sudan)
The Southern Adal - after the old Sultanate of Adal,
and the core Abyssinia.

The tech investments under research as as requested.
Since it's 1913, it's pricey to start researching 1914 AC, but you can.

On the Naval construction , I lay down the next 12 DDs, and an additional 12 MTB-Bs.
Since you discussed building another CA and 2 CLs, I put aside tonnage for that.

Above, it lists the results of the prior building.
For 1907-1912, you wanted the 1911 DDs and 1910 MTB-Bs, I tried to figure out how many you could have fit in the drydocks. So..24 DDs, 136 MTB-Bs.

On the Non-Naval is your Army/Airforce/Forts.
For now I'm suggesting build 2 Army, 1 Air, 1 Deployment and 1 fort/ turn.

Then I went and invested the surplus at the max of $5/turn in the two provinces you had in 1913.0. The 4 new ones will not be available until 1914.

Thanks Snip, I owe you one.

That will be the standard for the 20 x DDs, further mods will be for improved sea-keeping and range, but that's for the future.

CHANGE -

That type, and the 500t DDs, the MGBs, the Elena BC, and the TBs are all approved.

I still want to go over CL and CA designs, just what is on this page is enough to keep me busy for a whle.

This is embarrassing....
First, see below,
And it occurs to me that it takes years to build a Dreadnought, and that if I want a pair of ships that can make a stand against a real enemy I'd better get started on something like those South Carolinas that have already been suggested to me.
So.... my bad.
Too late to set that up?

Here is where I have a very different idea; I already have 30 fort points and only 5 places to distribute them (4 home ports and one colony) and a max. of 6 to spend at each place, if I am right about that... so I think that will be a Deployment point instead. 


ALSO - The only monitor with 12" guns for that year that I could find were the USA Tonopah types, and one look at them proves they are barely sea-worthy.
Dreadful things, and their fire-control is sure to be garbage, so I would be very happy to accept the Norse types with 180mm guns.

I'm not over-loading you yet, am I?

They are en echelon like Von Der Tan, kind of like in this picture.

I can switch to superfiring if you'd like. Any other changes you want? What guns are you going to be using?

Here is where I have a very different idea; I already have 30 fort points and only 5 places to distribute them (4 home ports and one colony) and a max. of 6 to spend at each place, if I am right about that... so I think that will be a Deployment point instead. 


ALSO - The only monitor with 12" guns for that year that I could find were the USA Tonopah types, and one look at them proves they are barely sea-worthy.
Dreadful things, and their fire-control is sure to be garbage, so I would be very happy to accept the Norse types with 180mm guns.

I'm not over-loading you yet, am I?

Nope not overloaded, thanks for asking.

I will likely miss things.

Fortifications are assigned on a regional level, not a location-specific level. Since your forts existed before you picked up colonies, they can only be assigned the 3 home regions.
On the sample turn I provided, I have them divided up land/coast and by region on the "non-naval" tab.
Since it's your nation, you're free to move them where you want pre-start.

The 180mm + 118HOW would be a Parthian export designed & built for Ethiopia. Easy to slot in.
The Fire Control you currently have is 1905.
I would strongly suggest you research the next fire control as a priority instead of signals int.
I would also strongly suggest waiting on 1914 aircraft until 1914...otherwise it costs more and you only save 1 year.
Did they beat the drum slowly,
Did they play the fife lowly,
Did they sound the death march, as they lowered you down,
Did the band play the last post and chorus,
Did the pipes play the flowers of the forest
