Parthia & Byzantium should think about building big 45,000t machines.

Playing around with cruiser-of-the-line ideas for the mid thirties.  This is basically a super-Czarownik, with newer 400mm guns, DP armament, and heavier deck armor.  The transom stern is assumed to be available at this point, we'll see how it actually shakes out.

Obviously other options include a heavier version with 450mm/45 guns and a lighter version with the new 350/45 I'm working on.

It'll all depend on what use I actually see for battlecruisers at that point.

For 8000t cruisers - 1933, Byzantium test several projects,
mostly:
4T2x191 - 31kts - 13000nm - B100
6T2x191 - 30kts - 12500nm - B100
The project with 6T2x191 is selected because its 50% greater firepower is preferable to 1 additional knot.

He was around when I built the first batch.  Adding the amphibious capability was actually his idea.  Think he just didn't have the resources for any of his own.

Light Transport - I have a very similar vessel. I wound up devoting only part of the available wt to Fleet support, while allocating the rest to a variety of things.  That's a fair amount of tonnage, you may want to pencil out what it supports, and also look at your Destroyers and subs and see if the result is a whole number.

Koraz- I think Foxy would salivate at such a tip and run commando vessel.

18 January 1931

The official keel-laying ceremony takes place for the battleship Jan Ingenhousz, although steel has been laid since yard workers were sober enough on 2 January to do so.

With several members of the royal family under the weather with some form of flu, the Crown is represented at this event by Queen Christine and Princess Edyta.  The queen graciously permits her seventeen year-old daughter to take the spotlight on this occasion, and the young royal delivers a brief, ghost-written speech about the workers and the city which will spend the next four and a half years building the mighty dreadnought. 

Afterward, yard workers are prepared to admit that it wasn't a bad speech, and the event wasn't quite as disastrous as they expected it was going to be when they heard who would there. 

18 March 1931

The battleship Znakomity arrives in Stockholm to begin the process of paying off, beginning with the removal of all ammunition.

She is the last pre-dreadnought battleship built for the Vilnius Union navy.  Originally intended to be the second of five Wspanialy class ships, construction of her sisters was terminated early in 1903 as the Union came to recognize that a new era in capital ship construction was close at hand.  Refurbished in 1921, she was jokingly referred to as the World's Deadliest Pre-Dreadnought by her crew, despite the reality that she would fall short even in that regard.

Over the course of the spring, she'll be repurposed as the new centerpiece of the Stockholm Museum of History, drawing memories from the aged and wonder from the young.

28 June 1931

The battleship Friedrich Herschel commissions into the Navy, joining her sister Johan Gadolin in Battle Squadron Four of the High Seas Fleet - the Znakomity's former tasking.

Herschel displaces three times more than Znakomity, and her eight-gun 400mm battery dwarves Znakomity's four 280mm guns, making it fairly evident why the aged pre-dreadnoughts are no longer in service. 

Herschel is the last of six capital ships built under Phase 3 of the Union's Naval Replacement Program.  She and her sister are operationally compatible with the slightly older and less-big Encke class as well as the Czarownik class cruisers of the line, all mounting 400mm guns and capable of at least 27 knots. 

It is not clear that there will be a Phase 4 in quite the same way as the previous phases.  The recently laid down Ingenhousz is the first ship, her sister Joachim Jungius will be the second, and a second pair of similar battleships is expected, but the navy has not publicly committed to specific plans for armored cruisers or cruisers of the line.

Okay a small transom and 1934 engine year gives me 31.6 knots and another ten tonnes or so of deck cargo.

Speaking of korsarz, another look at a new class.  This one's built with less emphasis on launching MTB attacks and a bit more emphasis on a fast transport/rapid strike capability.  This means fewer davits and more raw cargo capacity.  In theory, the following missions could be performed:

-MTB strike:  4 x 20t MTB in davits and another two stored on the aft deck, with about 32 boat-loads of wet/dry stores aboard.

-MTB tender:  As above, but additional MTBs in company as well as those carried aboard.

-Naval infantry strike:  120 marines and 30 boat/vehicle crew, with up to 4 to 6 landing craft or gun tubs and possibly some light vehicles on the aft deck

-Fast transport:  Up to 600 personnel for 24 hrs plus additional deck cargo in lieu of landing craft, on top of existing stores capacity and possibly some off-loading of bunkerage.

I considered a fast minelaying capability but figured that would require actual refits to switch roles, whereas the above is a matter of what is in the davits and what stuff is on the deck.

A full 32 knots would be nice, and I may sim the effects of a transom and see if it's worth waiting a year.
