Economical for colonies, but need new 100m shipyards.
I'll not comment on the details of the craft, except to say they need a row of underwater viewing ports, with thin glass scuttles.
I have been repeatedly extending dry docks and have built many new.
I am now considering pairing 20m & ~80m with the series I built in the territories.
I will note your reserved weight includes for paravanes.
Paravanes are included in the mine tech, so you can just mount them right off.
Also, I at least have reduced the ventilation tonnage on my new ships.
While we still operate in warm waters, refrigeration and cooling equipment got better in the early 1900s.
So I figure I have some active cooling ability now.
Mines came up in the Caicos war, where Snips 2t were declared the 'primitive' and good for 10knots ~200m swept.
"Advanced" can be whatever you wish, but I am going with 5 tons. These are good for 15kts
They seem related to the ASW Kites. Same concepts at least. Which is where the speeds come from
For those that don't know, basically a winged float pulls cables out from the bow of the ship, forming a <---- where the < is the paravanes and --- the hull.
That way a mine can't bump along, or be sucked to the hull
The floats can be designed to dive slightly and so be a considerable distance underwater, and the The mines slide down the paravanes where either their cables are cut by a shear.
Either way, they can be brought to the surface and shot.
Seem to have pretty effective against moored mines, but only going forward.
Not an area of expansive knowledge for me.
I think for 1300t this is a powerful torpedo boat - 2T2x120 + 2x3TTx533.
If it is necessary in the future to install new material, TT, 76.2 & 47mm guns can be reduced.

Yes.
Comparable to my larger 1920 Palang Class, but 10% smaller.
The difference is largely due to my vessel having a larger fuel capacity and better seakeeping for the Pacific.
I haven't looked closely at historical ships to see the practicality of mounting a 2-gun 120mm
on a 9.9m destroyer hull, but early on the group decided that if it works in SS, it works in N7
so it does not matter.

Colonial ships are not meant to cross oceans back and forth.
They are assigned as "Defender" to the Madagascar zones and African coasts, Australia and Brazil.

I think for 1300t this is a powerful torpedo boat - 2T2x120 + 2x3TTx533.
If it is necessary in the future to install new material, TT, 76.2 & 47mm guns can be reduced.
Yes.
Comparable to my larger 1920 Palang Class, but 10% smaller.
The difference is largely due to my vessel having a larger fuel capacity and better seakeeping for the Pacific.
I haven't looked closely at historical ships to see the practicality of mounting a 2-gun 120mm
on a 9.9m destroyer hull, but early on the group decided that if it works in SS, it works in N7
so it does not matter.

One question - what is the design reason for your Auxiliary to steam at 21knots like your battleline?
As an auxiliary, being able to operate with the battle line is not needed, and we are trying to keep the two separated.
On..last tuesday? I made a similar Aux Patrol craft,
with 'coast guard' / subchaser and minesweeper variants.
I toyed with speeds of 19-20 knots.
Why? Because I wanted a speed 2-3knots faster than the surfaced speed of a submarine for the 'subchaser' role.
20 knots would interoperate with my battleline, so I went slower to 'defend' the Aux designation.

Quotemisc weight: 61t
1t for fire control
25t for Long Range Marconi
5t for additional ventilation
25t Cargo reserved in hold
25t cargo reserve could be used for temporary armament (minesweeper, ASW, AA guns...) ... if war. so 21kts is the mini speed.
Claiming 'AUX' is not automatic.
This is about avoiding use of the AUX rating to make a cheap warship
It is not a clear line in the sand. Which can be frustrating.
Plus I do not look at most ships. I'd like to but lack the time. I tend to look when called, or a different player is posting
and I wonder what the fuss is about.
So I expect that adds inconsistency.
But I believe the point of the 21 knot speed is to allow it to act as a warship in conjunction with
your battleline. Your reply that 'if war, so 21kts is the mini speed' ... confirms this.
That puts it in the 'cheap warship' category - 95t each.
Now, a fast 'cargo liner' is possible, but one with 5.6% normal as cargo is
not giving up much for it's auxiliary status.
I have used speed as a limit before - ask Foxy, he was rather unhappy with me.
I do not see a need for a AUX minesweeper or ASW vessel to make the speed of the battleline.
I can see them needing to sustain the cruise speed of the fleet indefinitely,
and so not needing more than 1/3 - 1/2 max power for cruise speed.
I can see them needing to sprint fast enough to catch a surfaced sub.
So the 17knots I gave as a limit for Foxy would have moved up to 18/19.
I don't want to bend the AUX rules.
I prefer to build Patrol Gunboats.
That is what I wound up doing with my Mackerel class. While it was slow enough, to do the role I wanted, I couldn't get under the 2%, so I paid full price.
I prefer this one, for patrols, escorts & reinforcement of the Fleet protection.

Main Guns => 3 x 102/45 can be replaced by 2 x 120/45 (?)
Yes.
The 'Main Guns' part in the reconstruction/refurbishment rules is not well worded.
That should probably be revised to 'turreted guns'.
Deck guns, even if the 'main guns' can be basic refitted to something else.
For TGB650:
It is not a reconstruction but a choice to be defined for 1922 construction.
3 x 102 => 30 to 45 rpm - 14kg shell, or
2 x 120 => 20 to 24 rpm - 22kg shell.
Ahh sorry, I misunderstood.
I really think you should go for an all 8mm MG layout.
My ships would really appreciate that.
...
I will leave my OP Force's gun choice uncommented on, unless asked.
Oh, peeking at NavWeaps, I think those ROF are high when compared to historical mounts.
However, with longer ranged shots, there is a limit on ROF due to the need to spot for accuracy,
something that can be disregarded when one starts to hit.
Final type, TGB800 with 2T2x102 choose for the fire density. Excellent vs MTB & TB, correct vs DD.

I may have anticipated / misunderstood the rule:
Quote
1920: No restriction (high or low) on caliber of turreted guns. Cruisers under 3000 tons may have composite hull strength > 0.75, Cruisers under 8000 tons may have composite hull strength >0.90
This techno is just 5.00$ in 1924H1... not 6.00 => techno not valid.
Byzantium TGB800 (1922) & TGB860 (1924) are SS with " Cruisers under 3000 tons may have composite hull strength > 0.75 "
I think that they must be 0.9 not 0.75 ... ?

Yeah, always awkward when tech advancement isn't quite where you think it is when you start a ship.
To comply with the rules (OA 0.9), the speed of the TGB800s is reduced to 25.2kts (was 27kts), they will be able to work with the old D750s (25.5kts) newly assigned to TGB missions.
No $ & BP changes in 1922 reports.

Nope, that vessel is under the Cruiser architecture, not DD, so no speed bonus.
Speed bonus delete in TGB topic.

Why singles and not three twins or two-guns?
QuoteWhy singles and not three twins or two-guns?
I think singles have a little higher ROF than singles, but gunners are less well protected. A hit on the upper turret can neutralize all the personnel of the 3 singles.
I prefer the 3T2 assembly.
Equivalent to 2 "O" class but more powerful.

More economical than a Destroyer and more effective in fighting against MTBs which proliferate in small Navies,
these TGBs can work with 27kts colonial cruisers.
The lack of a published Ethiopia navy is unfortunate, but it likely has quite a number
of light combatants to guard their coasts.
The carrier is interesting, I think to limited for my taste, but similar fighter carrier concept to the Bazdari class... fun to see a range of options out there

CVE studies will start from this SS with an increase in the air group, armament or both.
