Just a basic CDS for Siam, to be laid down as part of their 1912 budget.
Made with 'outside assistance,' the ship will signal the end of New Swiss involvement with Siam and the dawn of a relationship with a new ally...

Who might the new 'ally' be? To tell you the truth, I did NOT want Siam allied to NS when I had Siam, unfortunately no one else was willing to help Siam.
On small detail, Siam used inches from 3" upwards and millimeters from 75mm down. So it would be 12", 6" (or 5"), 3", 50mm 25mm...

It's capable, but there's a lot of light guns being stuffed into that rather modest hull.

Why not just upload them in the enyclopedia section?
No uploading is needed, please.
I already have them. :)
Again, no uploading needed.

They fit quite nicely into the hull. If I had gone with a bit more beam and a slightly heavier ship, I could have fit another pair of 140mm into the hull. Now, those 140mm aren't going to be useful in much of a seaway, but the Gulf of Siam seems like a nice, quiet place for the most part. They should be useful in the coastal environments that this ship would be most suited for.
I was thinking in terms of weapons volume and deck space, rather than weapon weight.
However, a skim of references suggests you're right in this case, so I withdraw my comment.
Ahoj!
Wouldn't a twin on such a small hull be better?
Borys
A twin for the mains?
Siam lacks a proper gun for that, as does the sponsor.
Perhaps the follow-up will remedy that problem...
If a willing construction partner can be found.
Siam has a lot of obsolesant vessels that need scrapping.
They might be in the market to trade scrap for a ship.
Also, a lot of NS tech was transfered to Siam... so that's out there, too.
Two singles work better on that beam, give you 360 degree fire, and keeps the ship from losing her entire main battery in one hit - I'd stick with what you have there.
