Protected and Light Cruisers

[The Rock Doctor]

Oyono Class Light Cruiser

The Oyono class light cruisers are slightly larger than the preceding Volkhov class, mainly to allow for incrementally better protection.  Visually they're similar enough that I won't bother sketching them.

The Union would like to get to the point where it can lay down a new light cruiser every six months, until the heat death of the universe, but it's not 100% certain that the Union's BP count is up to that task along with all the other stuff the Union wants to build.

Ogun Class Light Cruiser

A small CL for "guard" functions in colonial waters - trade protection, leading torpedo-boat divisions, etc.

And right now I'm scrapping a few of those cruisers, and the rest are all pre-1910 designs that just can't keep up with torpedo-boats or travel long ranges.  So I need a bunch of replacements, and pretty quickly.

A group of six lets me put probably two each in North America, Africa, and the Azores, while the South American territories continue to get by with old stuff.

Angerman Class Light Cruiser

New light cruiser to screen the Kirasjerzy class armored cruisers.  It's possible I'll extend the run to add escorts for the two Zuraw class carriers which are or will be building.

Realistically, I should have started these a year earlier to match up completion dates, but for now I guess the first two ACs will get a year or so of escorting from Ogun class ships.

Compared to earlier eight-gun ACs, there is the transom stern, a heavier belt and barbette, and more bunkerage to keep pace with the ACs.  A bit more light AA and weight reserve as well.  Seakeeping was a consideration, given that these guys will probably spend a fair chunk of time running around the Atlantic.
