And that's 1000t normal displacement, although undergunned as all small Austrian ships (unlike the overgunned BBs). I'd check out UK and US destroyers on Wikipedia.

The minimally smaller GTB 1913 (oil fring!) had 3x88 and 2x2 TT, 2x1TT

the Tatra was coal firing and capable of 32 knots (I wonder for how long .. )

If I was shoveling the coal... probably not long. ;)

Drawing such a vessel..; I barely can resuffle things on a battleship in paint.

if somebody else could supplement me (unfortunatly that Canis D still suffers from bad eyesight), I can be gratefull.

And yes, I realise that I like many guns on my Gloriously decadent French ships. And yes, that superfiring for destroyers and smaller are not in my technological grasp (not that anyone commented on that)

So, the new idea.
The 3 105's are kept, nicely distributed.
The 2 casemate mounted 70mm guns are kept, those are in the forcastle, smack in the largest space available for the sailors.
Removed the 2 centre side 70mm guns
4 25mm machine guns in nests on a small deckhouse what is build around one of the smokestacks.

The 2 torpedo tubes are just behind the bridge/smokestack and before the deckhouse around the second smokestack(with the machineguns), then the 105 Q gun , followed by a smokestack.
Further aft you have again 2 torpedo tubes and the last 105 gun.

A very basic scetch, the large scale i use is not very good for small ships, so the 25mm guns are not shown. And i placed the 70mm guns in deck mounts rather then casmettes.

150 mines, mine sweeping or troop transport capacity for up to 100 soldiers.
A short ranged marconi and a bit of comfort increasing measures make from these nifty ships a potential posting to be wanted.

The bow tube can be a nasty surprise for the moment an attacker daring to come in range.

The Rock Doctor

Like I asked about Korpen's minesweeper - is the freeboard representing a continuously sloping main deck?

I'm coming round to the notion that any ship fitted for multiple jobs like minesweeping, minelaying, and troop transport ought to be fitted with the equipment necessary for all of the jobs at the same time.  This might be the case here, but you've not indicated the allocation of the miscellaneous weight.

maddox

The mine equipment stays, but for trooptransport the mines stay home, as the space, and weight are needed to put the soldiers in.

Hm, what about that decadence, even French mines have airco...

maddox

France has bought 25 sloops of the Fleurus II type from the UKN ,back in 1902. But now, after 5 years of operating them, the disadvantages are becoming clear.
The weak hull gets damaged easely, the cramped crew quarters and enginering spaces make these ships less than liked assignments.
On paper and during trials these ships looked great, good armament, good speed and good range. But what good is speed if every serious wave can buckle a hull plate, what is good armament if every hit recieved cripples the ship and what good is range if the crew is suffering cabin fever after a few days?

A proposal from the naval yards at Tricomalee

Janking out 1 boiler, reducing available HP, reducing range and cruise speed to reduce hull load.
The same for torpedos and guns. Removing 2 70mm QF guns and 4 25mm machine guns, 2 tubes and all the spare torpedos, installing a newer Marconi unit.
These alterations would yield a real sloop, not a Destroyer on steroids.

Ahoj!
Much better. Although I don't see any decrease in HP.
Maybe part of the problem is having 5,5" guns? Maybe cut back to one such weapon?

Machinery weight should the same, a boiler is more than 100SHP, but it is marginal so does not matter. The rebuild is essentially removing all the above-mentioned stuff, and reinforcing the hull on the expense of coal capacity.
The cost of such rebuild, combined with an early refit would be 0.2BP and $1.7.

I'd also increase ammo capacity, there's enough space for a bit more.

A refit of .2 Bp, isn't that a bit excessive?
All France does is remove stuff.

For a .2 BP refit France could use the rules and fit in oil firing, that would give me no reduction in speed or armament.


P3D

The difference between the light displacements is 171t. That steel comes from somewhere - all that extra tons go into the hull, see weight breakdown. Make it 0.17BP if 0.2 is too much, I just rounded up to reflect that the reinforcement is an afterthought.

My $ cost figure was completely off, make it 0.17BP and $0.20 (or $0.30 if you make a full refit).
Oil-firing would mean throwing out half of the new boilers, an additional 0.4BP and $0.8
