Title: Ethiopian Navy
Post by: Kaiser Kirk on August 08, 2020, 12:56:44 PM
Placeholder for now.

Will be attaching spreadsheet with proposed starter forces.
Eventually will also attach "starter' HY1, 1913 turnsheet.


Then will do RFP for any class needs unmet.

To give Anchor Steam something to look at while I tinker....

1) A 1904 Regina Elena style AC with 255/50mm guns, heavy armor, and 25knot speed.

2) A 1903 rail or road transportable gunboat - beam of 4m, length 20m, either on a special flatcar, or on skids dragged by steam traction engines.

3) A 1900 Torpedo boat (destroyer) adapted from a japanese one.

Ok,
Attached is my draft suggestions for the Ethiopian Navy 1894-1906.

The first tab is the drydocks. They can be expanded later if desired.

The other tabs have the various classes, and then "Suggested" is how many I think the Ethiopians should get.
In some cases that is 0....
Basically that ship is an option, but I think another way is better.

The 1906 builds do go over slightly, so ~500 tons would be removed from the 1907-1912 builds.

Oh shit, that's a lot to go over!
And yes, I can do without 25k to get the docks I need. In fact, I was already wondering about that kind of thing.

ALL of what I proposed was notional and I figure that a lot of it won't happen the way I imagined .... Ship already showed me a better 1,000-tonner than the one I had in mind.

Give me some time, this is a LOT to go over....  :o

Ok,

More than "OK", wow! The MGB is exactly right, the TBs look exactly like a 1900 should, and the Flagship has more armor and exactly the speed I was hoping for.
Seriously, for a Cruiser-killer it looks practically indestructible.

Great job, can't wait for the chance to repay the all favors!

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 :)
Title: Re: Ethiopian Navy
Post by: Kaiser Kirk on August 08, 2020, 04:33:34 PM
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.

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.

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.

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.

Post by: Kaiser Kirk on August 08, 2020, 11:29:03 PM
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.

With some slight tweeks as requested.

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?

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.

   Direct drive, 2 shafts, 13 600 ihp / 10 146 Kw = 21,92 kts
   Range 4 000nm at 10,00 kts
   Bunker at max displacement = 623 tons (90% coal)

...

   Cramped machinery, storage, compartmentation space
   Adequate accommodation and workspace room
   Ship has slow, easy roll, a good, steady gun platform
   Good seaboat, rides out heavy weather easily

16t for 4TT x 18'' +4 reloads
18t for climat control
60t for 60 minen

1909 refit
10t for Marconi

This is an interesting design.
I need 3 mine-laying cruisers and this would seem perfect for that, but I have to make room for more mines. The only easy thing to remove would be the TTs, and that only gets me 16 more mines.
Can I remove 20% of the Bunkerage and get 124 mines? That would get me an even figure of 200 mines and reduce range to 3,200 miles.

So on your "Ethiopian Ships", in the 1898-1903 Tab you can put these in and see what changes you need to make room for them in your 'budget'.

Right now, that tab has 2 Roman and 2 Parthian cruisers. The Romans carry 30mines, the Parthian 160.
You can remove some/all of those and put these instead.

Under the <= 1897 tab there are 3 Byzantine cruisers with 40mines each.

Yes and Yes

All I need today is a link to this Sample. I am working on a TO&E for what I have so far so that I can visualize what I have .... and make better choices about what comes next.

So that I can get a handle on this, can I assume that the 3 areas are as follows-
North; the Red Sea
Central; Djibouti and its environs
South; Berbera, the Horn, and the Colony (Lumbo)

I will go with that, and post what I come up with in a couple of hours.

I (Zwiazek Wilno) have a 4,700 t coal-fired monitor (Wasserkuppe class) with a twin 11"/45 cal turret, 4m draft, great seakeeping, though only 10 knots speed.

That's why the next monitor got a full secondary battery, torpedo bulkhead, and more speed.  Well, it's less slow, anyway.

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.
Yes and Yes

All I need today is a link to this Sample. I am working on a TO&E for what I have so far so that I can visualize what I have .... and make better choices about what comes next.

So that I can get a handle on this, can I assume that the 3 areas are as follows-
North; the Red Sea
Central; Djibouti and its environs
South; Berbera, the Horn, and the Colony (Lumbo)

I will go with that, and post what I come up with in a couple of hours.


The draft turnsheet I already posted, you must have missed it with everyone else posting stuff up too.

Darn it, I felt having a turn sheet would be useful for you to see how this all fits together.

Here it is again.
I called the regions Kush (Sudan), Abyssinia and Adal (a Sultanate that held the southern part of Ethiopia).
You can call them whatever you wish, or add more- up to 7.
Right now there's no map showing the regions, it's basically for illustration purposes.
You can have 3-5 roughly equal sized.

Edit : Included another copy of the ships one too.

First, I will try to load a map and see if that works -
Title: Re: Ethiopian Navy

That's the basic arrangement.

The Homeland regions are supposed to be roughly the same size.
There's 32, and 3-5 regions, so roughly 11, 8 or 6.

Kush was north and a little inland : https://en.wikipedia.org/wiki/Kingdom_of_Kush (https://en.wikipedia.org/wiki/Kingdom_of_Kush)

Abbysinia was the Middle and coast , you might want to call it Aksum.  But it's where the Empire started and expanded from : https://en.wikipedia.org/wiki/Kingdom_of_Aksum (https://en.wikipedia.org/wiki/Kingdom_of_Aksum)

Adal was Djiobuiti to Berbera and inland : https://en.wikipedia.org/wiki/Adal_Sultanate (https://en.wikipedia.org/wiki/Adal_Sultanate)
Showa was the one prior to it.

They are just suggestions, you can go with what you choose.

Hey, it worked!

Okay, now that I have that....

I got the one about the Drydocks, but this is the first I have seen the other spreadsheet and it looks like a doozy.  I see that my Aux. Mercahnt tonnage is only 7,000.... won't be making much money off that!


SECTORS-
I am trying to make something that is rational for Naval purposes and suits my needs. I actually built my fleet around this idea in my mind before we started.

STARTING OOB

North; this is a defensive force built to take advantage of the many islands and short distances in the area.
KUSH —
11 x 500-ton DDs
44 x TBs
72 x MTBs
4 x MGB (Nile River)
1 x Monitor
2 x Mine-Layers
5 x Mine-Sweepers


CENTER-
This is where all the heavies will be based, and where they are made, too. From this location they should be able to react to any threats to either of the other Home sectors, and they can't be attacked until a threat enters one of the other sectors.

ABBASYNIA--
( All heavies, Cruisers and 2/3rds of all support ships....?)
15 x 1,000-ton DDs
20 x MTBs
6 x MGBs (4 standing by for inland deployment)
1 x Monitor
1 x Mine-Layer
5 x Mine-sweepers


South/EAST.
The lack of good anchorages really hurts us here, but the only missions are advanced warning, anti-piracy and to maintain contact with the Colony
ADAL--
(CLs/ACs... at least 2 of them)
1/3rd of Support ships
6 x 1,000t. DDs
36 x MTB
5 x Mine-sweepers


JUMBA--
1 x 1,000-ton DD
1 x 500-ton DD
4 x TBs
6 x MTB
2 x MGB
1 x Monitor

Not much, but it's not much of a Colony.

So, does the method behind my madness seem reasonable?
Title: Re: Ethiopian Navy
Post by: Kaiser Kirk on August 09, 2020, 11:23:10 PM
The Category Tonnage totals are modified to reflect the "effective" i.e. maintenance cost. Foreign built costs more, Aux less.
The purpose of the Aux merch tonnage is for your fleet supply vessels. their fleet support tonnage allows you to keep your ships near full strength for extended periods with no decent base.

Aux tonnage did in at least one proposed version generate income, but not in this simplified version.

Here is a request for a Heavy Cruiser design for you Gentlemen to ponder, if you like.

I am still looking for a CA to fill my ranks out, a Pair of them in fact.
This is part of my 1910 build and I can have super-firing (limited) twin turrets, but if you need barbets to squeeze an extra pair of big guns in that could be acceptable.

Specs-
A light displacement not to exceed 10,100 tons.  (well, up to 10% over if you must)
A speed no less than 25 knots.
Armor and range will have to be balanced.... I need a ship that can pack-up the flagship but also be a Corsair that can range far out into the Indian Ocean if required.

adequate room and good sea-keeping are desired, so instead of heavier guns, let's keep to these-

    7.09" / 180 mm 45.0 cal guns - 176.37lbs / 80.00kg shells, 150-175 per gun
     Breech loading guns, 1904 Model
   
      3.54" / 90.0 mm 45.0 cal guns - 22.42lbs / 10.17kg shells, 200 per gun (?)
     Quick firing guns, 1906 Model

(as an alternate these guns are on the new DDs. I don't see all that much difference, but.... 3.94" / 100 mm 45.0 cal guns - 30.77lbs / 13.96kg shells, 175 per gun
     Quick firing guns 1906 Model

Same types of guns as are found in the flagship, so I assume these are allowed to me.

A healthy number of torpedos is also desired, 8-12 mounts plus reloads if possible.

Other than that, its up to you. so good luck! If it looks good enough, I may even start making more of my own like 'em.

And our first contestant is....

Oh, wow, a mini-Scharnhorst! At that weight, I could have 3 instead of 2. That would solve a lot of issues, I might even be able to stop worrying about ACs and so on.

The problem is, I don't think the range would allow it to go Commerce Raiding, I should re-state that in the OP.... or is that even allowed in this game?

Still open, but this sure gives me a lot to think about. Good job!

So, two of one or three of the other....
Does this one have better underwater protection, or whatever Snip was talking about?

Everyone is advising me to get a couple of big, slower preDreads or something to make a stand with, but I don't see the logic in that. What good will one Battlewagon do me if the major powers can show up with a dozen? My preferred tactic would be to give ground until I can strike at night, and then use swarms of torpedo craft and some DDs to hold the enemy by the nose while my Cruisers and best DDs maneuver around the flanks to break his legs.

I came here to engage in Naval Battles, to play with Tactics ..... is that a part of the game, or not?
Turn-lengths of half a year make me wonder, I'd better spend a couple of days looking at the Rules before I say anything more.

Folks - note on mine tonnage - Design Guidelines specifies
QuoteMines:  1 t per mine, including associated laying and storage equipment.

Opinion :
Slow battlewagons are relatively cheap - speed is expensive and also takes long/large ships. 
There the factor that most of the NPC-Player conversions are significantly far away from the original player's home fleets. 
It is difficult for them to commit substantial resources without leaving the "home fleet" low on resources.
This is why the Malta treaty has such an effect. Of course that wasn't around during this build period.
But for most of the NPCs, a capital -sized slower ship has some value.

Naval War with the Berbers is not happening. It's extremely unlikely one of the other European powers would operate an offensive war in the Red Sea.
So only 2 real 'powers' have potential in 1907.  One is my Parthia, which traditionally wants a Strong Ethiopia as a limiter on Byzantine. The other would
be Byzantine if they wanted control of both shores of the Red Sea.

Now frankly, Jefgte is really nice guy, and this game is designed for colonial conflict. So that is unlikely, but from an Ethiopian POV something to discourage.

So, Ethiopia shares the Red Sea with a major power, which has long been able to move his home fleet from the Med to the Red Sea fairly quickly and easily.
A slow and heavily armored Ethiopian PD is simply quickly faced by bigger/better armed Byzantine ships.
So in this case, I would think Ethiopia's 1907 vessels would be built to avoid being caught by Byzantine 1905-6 heavy warships.

Generally folks here are story development with the possibility of battle.
Snip wanted a design where the colonies are valuable, and so we can have wars over them, more than "fight for survival" in homeland vs. homeland fights.

War does/is occurring.  Both between two players and a player vs. NPC.
There are two variants of that.

A) Two or more players with a story to tell work out a storyline of a conflict. I'll review to see that the conflict falls within the available technology.

B) There is a conflict, and I wargame it out using a base of Seekrieg IV with modifications for our tech rules. I'll ask players for general orders/goals for their commanders.  Which sometimes work very planned, and in a couple cases just have not gone as envisioned. 

Torpedoes have been abberently successful in the game so far, in A by choice, in B by dice rolls.

So this is a great comparison of the "price" paid for speed.
Virtually the same tonnage as Foxy's 6250 ton 8x 180mm, 25knot ship.

Close in date, 1909 vs. 1910 isn't a huge difference..with 1910 engines about 200 tons more 'stuff' could be fitted.
Coincidentally, with 1910 engines, the belt could be 150 and so the slopes of the protective deck could be 180mm..

20m longer, and 2 knots faster.
Also 8x 180mm,

but instead of a narrow 181mm main belt and a 102mm upper belt, with an overly thick 51mm protective deck...

just a protective deck - albeit 150mm on the slopes and 30mm on the crown.

In a slugging match between the two, this one looses. But she's faster, longer ranged, and better seakeeping.

That's the fun of ship design - making design trade offs :)

Advice is just that, advice. Everyone has a different way of doing things, but its up to you to decide which direction you want to go. Slow pre-dreads are useful for certain people and places, but not so for others. If you don't find them useful, you don't have to go that way.

I will just point out that swarms of torpedo craft have already proven quite effective, and people are already looking into countermeasures, so its something to keep in mind going forward. And as the one that took the brunt of them, my approach is significantly different that everyone else.

Well, it is good to know that I didn't make the wrong choice, just a different one. I would have had to shelve the CAs to get one Radetzky or a Vermont.

I will probably get two of one and one of the other kind, but I will leave this open for one more day.

Then I have to go back and see if I have any tonnage left for CLs....

QuoteNaval War with the Berbers is not happening. It's extremely unlikely one of the other European powers would operate an offensive war in the Red Sea.
So only 2 real 'powers' have potential in 1907.  One is my Parthia, which traditionally wants a Strong Ethiopia as a limiter on Byzantine. The other would
be Byzantine if they wanted control of both shores of the Red Sea.

Byzantium is in charge of free passage through the Suez Canal for members of the Malta Treaty.
The Ethiopian Pirates of the Red Sea were eliminated by Byzantium in 1910-1911. The area is now secure.
Byzantium will further increase, if necessary, its means of enforcing this free passage.

QuoteNow frankly, Jefgte is really nice guy, ...

Exellent Analysis  :)

I think TorpedoBoats / Destroyers would be most effective in this narrow sea.
Now, if Ethiopia wants to acquire exterior colonies, Ethiopia could consider limiting the number of "Red Sea torpedo boats" and increasing the number of this AC - CL & transports...

The current Emperor was not in office at that time.
The conclusion of the Piracy affair is something you may not be aware of. All Pirate survivors that managed to escape you and make it back to our territory and subjected to the "twice punished" regimen. After a public flogging (for losing to you) they were forced to make a choice (for persisting with Piracy in the age of steam) and all those that chose to do so were allowed to join the Navy.... as Enlisted men.   :-X  The alternative to that choice is not known, but none of those that refused enlistment have been seen or heard from since.

The matter of free-pasage in peacetime is considered closed, and all ports are opened to free trade with any nation on Earth at this time.

Excuse you?

Ethiopia has enough to do one the Home Front, but that does make me wonder if we can do a little better than that one lame little colony that is so far away. I was considering putting it up for sale, but now....
The very idea that an outside power is telling us that our ability to take and maintain colonies is dependent how we distribute our ships in our own home waters is , shall we say.... controversial?

And before the usual stuff begins, feel free to have a look at the old Pirate strongholds in the Dhalek* Islands, and you will see that they are under new ownership.

*yes, that is what they are actually called, I guess the BBC had a good Atlas when they were looking for crazy names.

That's not what Jef meant, I'm sure.  He's noting, out of character, that larger warships are more capable of projecting force out to overseas colonies than torpedo craft. He isn't giving in-character instructions.

Aw darn, I'm sorry!
I thought we were already getting into the chatter among world-leaders part, Role-Playing. My bad.... but I do like to play the twerp making a brave stand.


And, it turns out that I totally fucked up my own fleet-making here.

I thought I had tonnage to play with up to 1910, but it turns out I was wrong. It was staring me in the face the whole time, but it never really registered. I had over 120,000 tons for 1900-1906, and only about 20,000 for the next 6 years. I guess everyone went on strike for 5 years.

Had that last category set for my best series of DDs, but that's out now.  I won't let your work go to waste, I will take one of each of these 1910 Cruisers  (is there such a thing as "medium" cruisers?  ;) ) and maybe go from there.

Result- one of the heavier-firepower version from Desertfox and the one from Kaiser Kirk with the long legs.

Looks like I have 37,000 tons of pre-1907 stuff to get with a max of 255mm guns for them. Meh, I'll figure it out. Time to take a look at the older submissions. Looks like a couple of Von Der Tann will fit the bill nicely.

Hey Jefgate, looks like you were right. Armed Transports and fewer DDs will probably be the order of the day.   ::)

Okay.... baring any fresh disasters, I am ready to start learning how to play this game.
Whew!

Thanks, but I had 4 screens going at once most of the night, I think I'm good with what I have! And even if they have flaws, that's fine, this navy is bound to have its share of glitches. I have to move on and dig into the rules.

.... once I get my OOBs and Stations cleared up, that is.

BTW - those docs can't be read by my mac, and there is no app in the store for them either.
Actually,  I went with a different SC anyway, it fit the year better

EDIT --

Okay, I have the new OOB set for each location, and the winning types are located under ship classes and have a line that looks like this if they were accepted and one that looks like this if I had to turn them down.

Still waiting on that custom BA......  and, somehow I lost the Stats for the 500-ton DD that I now have 2 dozen of as my only DD now.  Kirk, were you the one that showed me that, with 3 x 90mm guns?

One of the ships proposed was a 1904 Parthian "Spear" class 500 ton DD with  3 x 90mm bearing forward through the use of Omaha style superstructure casements, and a pair of german-style forward firing torpedos firing through the forecastle cheeks.  Aft is a second set of torpedoes and a 90mm.

As a practical application thing, it's probably bow heavy and would pitch in deep ocean, but gamewise it's great for the Red Sea and still has respectable trial speed. So a good 1904 DD.

This  Class of Destroyers are an effort to exploit the turbine technology for further speed. The first true Destroyers rather than enlarged ocean going torpedo boats, they are Larger, faster, and better armed. They sacrifice about 1/4knt of performance for slightly better seakeeping, allowing them to operate in the Persian Ocean.

Trial Speed is : 26.3kts + 2.75 : 29.05kts

These little ships rely on boilers burning coal boilers oil sprayed coal, there is sufficient fuel for a 10 day journey, with a 10% reserve. Of the 8 boilers, 2 are 100% coal, and 6 are oil-sprayed coal. They can manage 18.71 knts on the coal fired boilers alone.

The guns are arranged with A and Y, but with  two casements in the superstructure (like the Omaha CLs)  clearance forward, giving 3 guns bearing forward, and 3 on either beam. The guns are equipped with 6mm spray shields.

Miscellaneous weight is as follows :
8t - 4x 18" mm torpedoes. Two torpedoes fire forward from the "cheeks" like an E-boat, and two on a turntable in the rear.
2t - Extra ventilation
2t - 1905 fire control
3t - Void, construction reserve



Speed with the single 100% coal fire boiler is 18.65knts, allowing virtually all peacetime activity to be done using existing coaling facilities around the Persian ocean.

Trial Speed: 25.6+ 2.75 : 29kts

1907 refit : 2t
2t + 1905 fire control

I'll take it!
The only issue is the turbines, which I suspect makes it impossible for them to be locally built. Upkeep is going to be difficult, but at least the last piece has fallen into place.

Yup, that's it.
I have a small BA (pre-dread) that fills the last of the tonnage out nicely, so it's time to post them both in the Navy lists.

Tomorrow.... no, Saturday I will put copies of my turn sheet so that I can show my progress and mistakes as I work through it.

The Spear class turbines are not a problem for Ethiopia, which has that 1902 technology.  It's >10% oil fire that you don't have, and that's not an issue with them.  Which is why they appeared in the Chinese navy (where they actually performed quite well in the last war).

Congrats on the slog :)

My timing might suck, but i forgot something.

My new navy is supposed to have 15 Minesweepers, and I don't have a design for them.

The only hard & firm requirement is a Disp. of 250 tons.
If they are simple enough to have been built here (coal only) that would be great!

Other than that, I dunno, surprise me.... ?

available guns include 45mm, 90mm and 100mm. Speed can be anywhere from 10-20 knots. and good sea-keeping would be nice... but do Minesweepers even do anything when the weather gets rough?
Hell, I'll take anything, so have fun with it.

The Ethiopians could copy & home build Parthian designs.

The 1902 version seems to fit nicesly.

1902 date
250t
90mm gun,
90/10 Coal fired
excellent seakeeping
double hulled

and I think you'll find most folks don't even have minesweepers back then. The Norse did- China used theirs.
Not sure about the Aztecs.

I forget the date of my mine warfare ships right off.  And mine are more multi role minesweeper,  mine layer, offshore patrol vessel.  I will probably be doing that as my future minesweeper as well.  An opv for universal deployment with a heavy emphasis on minesweeping and possibly asw.   Though the latter isn't important yet.

I thought I recalled seeing you have Minewarfare assets.
I remain unsure how practical it is to combine mine laying and sweeping, but that's not a field I've read much on.
I just don't recall seeing vessels kitted out that way, but that could be due to needing far more sweepers than layers.

I did it that way because it's a bit amateurish.

Honestly, laying offensive minefields with my MS-1 class would result in the loss of a lot of MS-1 class.  They're too slow, and you'd need to send 4-10 of them to lay an offensive minefield in any strength.  You really want a proper, relatively fast, minelayer with a relatively large capacity to do it properly.  But in a closed sea like the Caribbean, having OPVs all over the place which can drop mines and then somewhat quickly return to a harbor to load back up and repeat.....it's a possibility.

First off, I am hoping that geography has some effect on combat in this game. The south end of the Red Sea is suited to mine-warfare used defensively and the many little islands are great for TB operations... which is why the bulk of the older ones are there.
Our thinking is that since we know that mines can be so useful the other guys might know that too.

These are not just minesweepers, they can function as Patrol boats, Search & Rescue, Fishery protection and Revenue Cutters. They may even have started out that way. As such, I won't have to worry about them becoming obsolete any time soon. Mine sweeping is the one combat job such ships can do effectively, and I don't want to have to build more later.

However, that's interesting. Could they have mine-racks of their own? For more than just ten or so mines, I mean.
Title: Re: Ethiopian Navy
Post by: Kaiser Kirk on August 16, 2020, 11:04:46 PM
1. Geography does matter. 

2. Diplomacy may be a factor, remember a huge chunk of trade comes through the Suez canal.  How you choose to mine could effect the "European" players view of things as their merchants are damaged or sink. Historically where mines could be moored the sea was relatively shallow, like the red sea. If they weren't moored they could randomly damage shipping.

3. How you use them is up to you.

4. Functionally, it's a matter of assigning miscellaneous weight to the role.
I think I need to try to find some reading matter on early 20th century minesweeping to be able to answer why they didn't combine the laying and sweeping roles historically. Usually when something is obvious and they didn't do it...there was some reason...but not always.
Title: Re: Ethiopian Navy
Post by: Desertfox on August 16, 2020, 11:29:14 PM
I think the biggest reason was that minesweepers and minelayers tend to be very different sizes. Minesweepers are usually small, cheap, and more disposable with limited space for mines, while minelayers need a lot of space for mines and you don't want them near an active minefield. You can always put minesweeping gear on a minelayer and use it as such while empty but its more costly, conversely you can put mines on a minesweeper but it would only be a few. I can see a use for a small number of mines on minesweepers, where they can be used to maintain defensive minefields around a port, so you only need a handful of mines.   

One of the reasons I don't mix the two, is that I can build minesweepers to merchant standards, while minelayers have to be built to military standards and are therefore much more expensive.

Very good points!
And having a rack of mines on a small ship that could easily hit a mine itself could be bad for morale', eh?  :o


And on 2nd thought, I don't think I really need anyone to design a pre-1897 mine sweeper, especially if the function never comes up in practice.
