On the I-30 submarine, I think you're missing some fuel. Also, I wouldn't bother with large amounts of armor on the 210mm mounting, a hit on the pressure hull is more dangerous to you. But I would provide side armor, otherwise it looks like an open mount, which is probably not the idea.


On the Delhi, I'm not sure this ship is up to the task: while it may be capable of dealing with one of the Italian Saint class cruisers, it's really overmatched against the Caesars. Germany would recommend the use of a 280mm or larger weapon if the Caesars are a contemplated adversary.

The Delhi's are being constructed to give an edge against heavy cruisers and to give help in a pinch escorting carriers. Their intended task is not to fight the Italian ships, the refit of the Akbars is the Indian response for the Italian ships.

In regard to the sub will do the changes to the turret but I guess you're right, I mess up the range.

Springstyle notes say to use between 1/4 and 1/6 of normal displacement as misc weight for ballast.

This shouldn't hurt the design much, because you've got lots of stability to spare.

Quite true. You're looking at about 700-1000 tons needed for that. Not sure about how that will affect stability. It does tend to drop rather rapidly.

Done. Tonnage for ballast

Is India using the same 25cm guns the SAE has developed for their units? India surely would have access to the drawings if they ask....

India have experienc in triple turrets in that caliber (IIRC a monitor is armed like that) but newer guns in that caliber are most welcomed.

IIRC the monitors guns are based on the SAE design. Rocky?

The monitor preceeds the SAE ships - laid down in 1921.

Ah, okay. Thank you. Couldn´t remember...

Australia does not like that sub...

Heh, reminds me of when the Iberians/Italians didn't like a particular Mexican design!
