I'm internally debating whether to go with two 1,500 ton destroyers, three 1,000 ton destroyers, or a very light cruiser for H1/1919, folks. Private communication with several people has gotten divergent results, and...well, I'd like to seek ya'll's opinion on it.
I'd go with the 3 1k DDs. You need numbers. I'd even consider building 4 750t DDs instead.
Coast line is very short so numbers isn't really critical. I can see arguments many different ways. It depends on what you want out of them / expect them to do?
I want some heavy gun armerment, but the main purpose is to act as a leader to other destroyers...I would actually build the G-class of the Confederates if I had the engine tech...
To be clear, the 1,500 ton destroyer would probebly look something like this, with 3-4 5'' instead of 2 5.5'' guns. I would probebly use the extra X-sectional to add FC.

I would go with the 1K ton job man, not like you need fleet destroyers.
Yes, but with destroyers this large, I can outrun or smash anything within the Ukranian fleet....
Or make smaller ships mounting only one or two heavier guns and then two smaller destroyer like guns. Say a single 150mm cannon on a 750 ton ship.
Romanians don't need a ton of endurance. If I were you, I'd be building something more like 500t in numbers. Or something that can lay lots of mines.
Or one could get....creative.
Lacking oilers that can transfer the dangerous African coast and other pirate-infested regions of the world, the Romanian goverment decided to lay down an armed oiler, that had speed enough to escape from potential foes, and armerment enough to destroy anything that got close to it. The result is...the Revange.

But Romania is a major Oil Exporter you have the Polesti Oil Fields.
As a point Italian tanker routinely visit Constanta to load Oil, of course they also visit Russian ports to load the same and Coal.
You really dont need an armed Oiler at all simply dock and tank up. Unless you intend to be launching agressive moves outside the Black and Mediteranian Sea's.

Was Ploesti exploitable c. 1920?
The Confederacy would be interested in offering the Romanian Navy the following options:
1.) purchase of any Confederate Navy destroyers which become surplus to requirements.
2.) production of new-build G-class torpedo rams or TB-01 class torpedo boats.
3.) drafting of a new design to Romanian specifications, to be built cooperatively.
I would go ahead with that, but at this point, the only thing that's going to be being laid down is a few hosipital type ships.
Yes Guinnes , the Ploesti oil fields were expoitable in 1900 and earlier.
Guinness, according to a link I'm reading, they started production in 1857.
