So late 1800s, mines become available, not to long after minesweeping is developed.

So I see the need for a couple different vessels. The minelaying scout cruiser and mine laying protected cruiser have been presented in the cruiser section.
This is the rear area minelayer, and a generic minesweeper.

Minesweeper
I seem to have lost that design, wonder how.... I'll have to recreate it.

[Kaiser Kirk]

And I thought my Dreads were going to be some of the bigger ships around.

Well, they still are.
Part of the problem of designing in a vacuum, I just set what I'm trying to build to, and then find out how big that is.
Then I compromise with myself, hence the Enki :)

[Kaiser Kirk]

I started with these ships as I had to figure out what the HMS Vulcan wannabe I posted earlier was going to carry. The dimensions of the TBs dictated how many I could reasonably fit on the Vulcan, and ...maybe I should call my Torpedo Boat Carriers "Spock" and "T'Pol" etc.... anyhow, it didn't take to long for me to realize that the TBCs would only be carrying the most recent TB, and that the ones built in the early 1890s really were not that fast later.....

So I expect to have some TBs from 1900 and 1906 still around, but no simple compound propelled 1894 Torpedo boats.

Meanwhile torpedo boat destroyers become another development arc.
I start with one designed at 210 light to get the full speed boost of +6knots. The next leap to 500ts and stay there, as they are fairly capable vessels.

The forecastle has a low turtleback deck, with the two 18" torpedoes firing through ports in the bow.
The 60mm quick firing gun is augmented by a pair of Maxim MGs for self defense.

Attack/Trial speed is 26.5kts

Range is sufficient to allow a 12 hour run with a 10% reserve. Range can be increased by reducing speed to 10knts to compensate for any full power attack runs.

1900 Destroyer 

This is meant as the first  torpedo boat destroyer, but with limited range and capabilities. The single 90mm is the claim to "destroyer"' status, but it's really a big torpedo boat.

1905 Destroyer 

This basic destroyer will be produced in numbers from 1905-1910, and so there will likely be a 1905 engine and a 1908 engine version.

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.

3rd Battery Shell weight too light


These little ships rely on 2 x 100% coal boilers, and 6x 10% oil spray, for 92.5% coal.
There is sufficient fuel for a 10 day journey, with a 10% reserve.

The guns are arranged with the B mount over A, and two waist mounts with clearance forward, giving 4 guns bearing forward, and 3 on either beam, but poor rearward fire.

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.
8t - 4 torpedo reloads
2t - Extra ventilation

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: 26.25+ 2.75 : 29kts

Ok, I think that includes all the designs I somewhat expect to build, except that missing minesweeper. I did these over the past couple weeks, there's 7 various Coast Defense BB designs, only got posted, one of which *might* be built.  I'm still debating if I want to do any gunboats. After Jefgte posted his, I started considering it, something for the Caspian and the Tigris/Euphrates.

Ah what the heck, may as well post it as a "maybe"

[Kaiser Kirk]

So as Walter astutely pointed out, I was confusing which techs we start with (<=1905) and when techs are available (2 years after listed), making some techs like the 1904 DD tech.. I thinking I'd have buy to have.

This means I have the 1904 DD tech, available 1906, and I need to finalize a 750ton destroyer design, and discontinue the TBs in favor of Type A MTBs.
This means the 1906 Engine tech - all oil fired, only costs me 2 modification points, not 6, to have starting in 1906.  So I'll be modifying the 1906 onward designs a little bit to run on 20% coal and 80% oils (why, because the various ports around the Indian Ocean would still be coal).

This also means the 1905 BB architecture I start with and it becomes available in 1907, and so would effect the Enki class, which will ditch the torpedo nets for torpedo bulkheads.

The 1905 gun class becomes available in 1907, but the weapons and turrets will be researching 1907-1908,  and won't be available until 1909.   
So I could start a new DN class for 1909 laydown, but expect I will wait until 1910, "in game"- I  already have a draft version prepped.   

So I need :
1902 Minesweeper
1906 Destroyer 750t, 80% oil fire, 8 TT.  Ironically, that helps answer my question on the 1908 AC, of if I should be going from 90mm to 120mm secondaries... yes. 
Shift the 1905 DD to 1904, produce in limited numbers.
1906 revision of protected cruiser
1907 revision of Enki class dreadnaught, oil and TDS.
1908 revision of AC for oil, possible TDS.
Possible 1908-09 stores ship.

[Kaiser Kirk]

Well after Walter pointed out that I was using Date Available (Date researchable+2years) as the determination for what techs I did and did not have,

I had to do a bit of re-evaluation.  At this point my original idea of just having 1894, 1900, 1907, and 1908 ship years for simplicity ...well that's dead now.

I've gone through and modified slightly alot of the prior posts. Typically the big impacts were 1906 oil firing and 1905 capital ship design.
I'll spend the 2pts to have oil firing in 1906 for the Gilgamesh class,  and will have capital ship design in 1907 - which means the Enkis can have torpedo bulkheads.
Now the 1905 Artillery research still finishes in 1907, which means new guns and turrets are available 1909, so I've moved my 1910 Tiamat (Babylonian goddess of the Ocean) class forward to 1909.

I've wound up making a spreadsheet for the later years to see when ship classes would start construction, originally to make sure I provided enough docks for them all.

So now the sequence is the Regina Elenas will build 1904-1906. The Gilgameshes can be laid down in 1906.  That means the new rule : Ships can undergo a Basic Refit when the hull is 75% completed for no additional cost or
modification to construction time, will apply to the Fire Control that comes into service in 1907, while the Regina Elenas will need a refit and the Enkis are built with it.  With the ways clear and the finish of Construction of the Regina Elenas in 1906, tonnage will be free in 1907 to start the Enki class. Then in 1908, the Gilgameshes will be

I've also played with freeboards here and there , or fiddled a bit with length or beam, but nothing terribly substantive - armor weapons and speed are all functionally the same.  In a lot of cases I trim the upper belt length relative to the main, as the main covers from A - Y barbettes, but the upper belt covers from B to X, a bit shorter. I'm presuming radio refits are cheap enough [Though I was just reading that an 1893 german ship was their first with radio, so perhaps no refits]  that I'll have done. I'd like to do fire control in 1907, but until I figure out what I've built, I don't know that cost :)

So now, Protected Cruisers have 1900, 1902, 1904 and 1906 versions, 16 ships to replace the 1890s versions. The 1902-1906 are fairly similar, just faster.  Once those are built, the 1908 ACs start up.

There's also a pair of gunboat classes , one riverine after the British Tigris River boats and one sea going for 'show the flag' missions.

Overall, at the current time my vessels are costing 477BP, I plan on spending some points to buy BP for the Docks. I'll have to make sure I have enough to have actually build these hulls.
Moved my discussion of hull counting to the nationbuilding bit.

So...what is new or significantly different that I need to post ?
1909 DN
1908 ACR
1908 DD
1907 DN
1906 DD
1906 PC - 1902/1904 are just the same with derated engines
1902 MSW
1899 Stores ship
1899 ML
1894 Gunboats - River and Sea

But starting to yawn, and gives me something to post tomorrow.

So, my bid for a "ruler of the waves", the Tiamat class.
I'm wavering between this one, and a 29,000 ton 0.602BC version with 365L40 guns. The 360L40 fire a 620kg shell at 840m/s, which actually higher than I want, though not up in the 850m/s I'm trying to avoid for dispersion reasons. The 365L40 fires a 645kt shell at 824m/s, which right at the upper end of what I want. It's only 600 more tons/ship, so I may do that.

Tiamat was a Babylonian sea goddess, to some a dragon, but a ruler of the waves. The Tiamat class is Parthia's assertion that she rules the Indian Ocean.  The dramatic increases in range over the past several years meant the older guns were less capable of belt penetrations at that range, which is solved with the new gun. Meanwhile, ship sizes had been spiraling upwards, and while Tiamat is 23% larger thant Gilgamesh, she carries 50% more guns and has far better underwater protection as well.

Armor Details
The upper belt extends from B to Y turrets,  rises to the forecastle deck foreward, and weather deck aft, and is capped by a 35mm upper armored deck.  With the mainbelt covering the bottom 0.5m,  42% of the upper belt extends 2m high and 58% covers 4.5m high, for an average height of 3.45m

The 350mm main belt is backed by a 65mm slope of the protective deck.  While the 350mm belt is expected to be sufficient at ranges of 10km, the additional backing is thought to be valuable if night fighting is to occur. The main belt rises 0.5m above the crown of the protective deck to prevent shells in a shallow dive from passing over the main belt and striking the slopes of the protective deck .

The Torpedo Bulkhead consists of a twinned 19mm (making 38) bulkheads,  followed by a damage control corridor and an 8mm bulkhead to restrict flooding from any leaks.

Following close on the heels of the Gilgamesh class, the Enkis feature much the same hull, but incorporate the new fire control concepts and torpedo defenses. As part of the expectation of this new system is greater ranges, the extreme armor of the Gilgamesh class can be slightly slimmed down, allowing a slightly smaller warship.

With the inclusion of torpedo bulkheads and increased range, the torpedo flats and torpedo nets are ommitted, but the hull blister is retained.

The forecastle rises slowly to the bow, but the total height gain of 1.8m (5.9ft) only conflicts with 0 elevation or depressed forward fire.
