Italia 1900 restart

The first post is a plea for help....

My research on the Italian fleet finds that in 1883 they ordered a series of Torpedo Boats from Thornycraft.
At 14 tons, little gnatss. Two were embarked on each of the Duilio class battleships.

With Centaro they ordered the lead 39ton craft from Thornycraft, and then built several in Italy.

They do try some larger MTBs, with a 108 ton from Yarrow...and Venice...in 1885

Then in 1887, they ordered 17 TBs, all 78tons from Schichau in Germany.
Then between 1887 and 1894 they proceeded to build 80 more domestically, to the same general 78 ton. 39m plan.

Followed by 1888's fancy with some 137 ton vessels from Schichau.

Overall, it's 120 MTBs. Displace as much as an armored cruiser, very nice for the Dalmatian coast, err Adriatic.
Our MTB tech starts in 1905 with something about what the Italians were fielding in 1887. That's a bit too late.

My attempts to sim have failed.  The BC just drops too low for our rules. Don't know what to do.
Anyone able to come up with a decent ship?

L: 39, 39.8oa (ram bow, stern overhang)
B: 4.80
D: 2.01
Tonnage, Normal : 78  (with the LxBxD, I get a BC of 0.205, which is out of range right there)
Arm : 2x1 37/25, 2x 35cm TT

1 shaft, coal fired, VDE, 902-1080hp, 21-22kts, about 1.5m freeboard from the pic. I'd guess 500+nm range.

Give them VTE's the tech tree was in error (and has now been corrected). The 1890 level was intended to allow VTEs from the getgo. Other then that I dont see anything wrong with Rocky's sim from a legality standpoint.

I'll leave that for Kirk to fiddle with.

Not a bad point-defence ship, though.

Thanks Rocky,
my mind was stuck in the hamster wheel of I have these historical dimensions and they SO aren't working out.
Esp at the historical speeds.
I'll tinker with it, but I bet I wind up with a clone. I figure I'll build just one or two types of MTBs to simplify things.

Thanks Rocky, Jefgte, between the two "looks" I should be able to generate something reasonable.

Still working on my concept for an 1880s PC with a ram and large bore gun mounted along the spine (lessons of Lissa).
I know, as the ship pitches up and down it will be harder to aim, so needs to be some giant casement mount,
perhaps nickname it the wave motion gun.

While we are not outright disallowing it, we really really want most combat ships to be in the 1890-1899 bracket.

Hmm, well, historically, 7 of the Italian Predreadnaughts were laid down prior to 1890. Overall, about 170,500 tons afloat in 1900 were laid down prior to 1890. Now in the mid-late 1890s, several were refurbished, rearmed and sometimes reengined- including some PDs.

Another issue is build rate, at 8BP/Half, that's 160,000 of the 240BP they get, of which ~40,000 should be "on the ways", so only ~120,000 of the navy should be 1890-1900 builds. Without deductions for the aforementioned reconstruction, or consideration they were building infrastructure in this time frame.

So, I'm happier to have more recent ships, they will be more capable overall, and we can just hand wave the problem that they couldn't actually build such a fleet in such a time frame....

Or, I could continue with a young/old mix, but be more aggressive about "refits" in the 1890s.

Ideas ?

I'm somewhat inspired by anime, Traveller, and the USN's dynamite gun. If the Ram was successful at the battle of Lissa, and QF shell guns were ~1885, then a small, fast closing target ram would be hard to stop. Add a BL 10" gun spinally mounted on it, and targeting is simple- aim the ship at the target, choose elevation, pull lanyard. OTL the Italians fielded Torpedo cruisers instead, so I was going to replace them with these if I could make the build work.

Anyhow, here is the 56S 78ton MTB.
Looking at our Torpedo tech, I upped the Torp mounts to 16" and allocated 1/2 ton each as that what the 1890 tech is.
I presume they simply refitted them for the "killer app" tube.

At all?
I got we weren't supposed to rely on it for weight, which is why there's 1 ton of misc weight for the 2x 0.5 ton 16"
I didn't get the "At all" part.
but thats why we post drafts

Any this is a quick example of the type of vessel I was talking about as a Ram.
The Piemonte was the first in the world with QF guns (supposedly), and she was laid down in 1887, finished 1889.

This ram is intended to charge towards her foe and transfix them with the 100 ton forward ram

The foreward 10"/32 mk II gun is fixed in traverse, but can elevate and depress, it is aimed by aiming the ship and hurtling towards the foe. A massive gun shield protects the weapon from ahead fire.

Behind the main gun are the double stacked casements of the 6" guns (ala Omaha CLs)

Scattered along the sides of the vessel are light anti TB guns.

The ship is designed as a protected cruiser, with 30mm flat, and 80mm slopes (50mm belt)

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

1880s
While we are not outright disallowing it, we really really want most combat ships to be in the 1890-1899 bracket.

Hmm, well, historically, 7 of the Italian Predreadnaughts were laid down prior to 1890. Overall, about 170,500 tons afloat in 1900 were laid down prior to 1890. Now in the mid-late 1890s, several were refurbished, rearmed and sometimes reengined- including some PDs.

Another issue is build rate, at 8BP/Half, that's 160,000 of the 240BP they get, of which ~40,000 should be "on the ways", so only ~120,000 of the navy should be 1890-1900 builds. Without deductions for the aforementioned reconstruction, or consideration they were building infrastructure in this time frame.

So, I'm happier to have more recent ships, they will be more capable overall, and we can just hand wave the problem that they couldn't actually build such a fleet in such a time frame....

Or, I could continue with a young/old mix, but be more aggressive about "refits" in the 1890s.

Ideas ?

So no further guidance from Snip on this.  What I'm doing is trying to reverse build. Produce variants of OTL vessels, amalgamating classes, figure out what they could have been spending tonnage on starting in 1899 and working back. Anyhow, that way I'll wind up with the youngest fleet possible. 

Historically, the older vessels were refitted in the 1890s, and I will have some older hulls with rebuilds as a result, notably the Italia class, which will actually be Dullio-Italia hybrids. Historically only Duillio was rearmed with 10".

Meanwhile I'm bogged down on trying to figure out the historic weapons and shell weights to use. Then I'll take in some real weapons from other navies, and finally produce some Ahistoric with the Naval Guns Reseach...but that doesn't scale for <8" worth a darn.


Oh, and on the "Ram"  - OTL, in 1882 the Italians laid down the Giovanni Bausan which was the first "torpedo ram"...at 3079tons and 18kts she sported 2x 1 10" guns, and 6 x 152mm. The Etna class followed.

Im a bit tied up today, so I can respond in more detail later. Is there a reason you wont just do construction from 1890-1899 with nothing funky?
You smug-faced crowds with kindling eye
Who cheer when solider lads march by
Sneak home and pray that you'll never know
The hell where youth and laughter go.
