Vilnius Union Ships, 1930+: The Good, The Bad, and the Unseaworthy

[The Rock Doctor]

Apparently I'm going to have a lot of fun designing a 450mm-armed battleship that can transit the canal.

[Jefgte]

Senator Tillman is back !!!

Senator Tillman is back !!!

I'd completely forgotten about that guy.

[The Rock Doctor]

It's kind of wild to think they thought they could get sextuple 16" mountings on a 34m beam with, I assume, a torpedo-defence system.

[The Rock Doctor]

It looks like Tillman #1 could be simmed in SS and made to work without much difficulty.  If anything, it's probably oversized for the capability.

Tillman #2 (4x6 16") isn't working at all.  There are a lot of problems but the main one is that the recoil is 1.86 or something.  I have to choose 2-row sextuple mountings cuz SS sensibly thinks nobody would actually want plain old six-gun mounts.

Tillman #3 looks like it could work easily enough.  Also looks oversized.

Tillman #4 kind of works if the block coefficient goes up to .79, cuz how else do you add 10,000 t without changing dimensions.  Recoil is still stupidly high, but everything else is nominal.

Tillman IV, with 18" guns, range from okay (13 guns) to not okay (16 guns), with recoil still a huge issue.

Of course, I cut corners and only built the canal to accommodate 250m ships, not 300m, so a Tillman isn't going to work anyway.  Unless/until I update the lock sizes.

[The Rock Doctor]

This would just squeak through the existing Trans-Eryka Canal.  It's a big no for the Kiel Canal but that didn't stop the Germans building the Scharnhorsts and Bismarcks past its capacity.

Nothing exciting about miscellaneous weight - FC, command, night-fighting, couple planes, etc.

Build time would be almost precisely five years, with almost precisely two on the ways.

Z Plan is coming!
H34 for Rocky!

I'm waiting H35...

[The Rock Doctor]

The Union military has...I dunno, lots of guys...deployed overseas at any particular moment.  For the army, we're probably talking tens if not hundreds of thousands.  For the navy, probably ten or twenty thousand.

A lot of those guys have wives and kids, and if they want to see them during long-duration deployments, they'll need to move overseas as well.

How does the army deal with it?  Well they probably just tell the servicemen to put their families on a liner.  But the navy, being all about ships, doesn't need to do that.  It can certainly encourage its officers to do like the army guys and just suck up the cost of relocation.  But it can also just operate a couple of dedicated transports to carry naval wives and kids from Amsterdam to the overseas bases and back.  This may not save money, but it might help with recruitment and retention. 

While the ship is primarily intended to transport civilians, it's probably possible to isolate sections of both the single and family berthing to accommodate whole families and single men if required.

The class is fitted for but not with a limited defensive armament.  The tubs for the 50mm guns can be seen just aft of the funnel.

If I wasn't mistaken, I'd think that the Vilnius Union has found itself needing to jump up to match a battleship just entering production?

This would just squeak through the existing Trans-Eryka Canal.  It's a big no for the Kiel Canal but that didn't stop the Germans building the Scharnhorsts and Bismarcks past its capacity.

Nothing exciting about miscellaneous weight - FC, command, night-fighting, couple planes, etc.

Koloni Panzerschiff with 2T3x457/40 is over 22500t

[Kaiser Kirk]

Ah, memories.
Once I thought it would be 'cool' to have a 510mm gun/missle launcher
that one could fire bombardment rounds... or an ASROC style torpedo from.
To heck with diving shells, drop a torpedo in the water !

Now I realize there are some technical issues with that.

0.9 hulls - not there yet. We do need to figure out what techs are needed for the mid1930s to make 1940s vessels viable.

[The Rock Doctor]

I don't think Wesworld ever got above 18" guns so I have the itch for a 500mm and all the waste that goes with it.

Noted on the carrier.  Thanks for the clarification.

[The Rock Doctor]

Big fast oiler to accompany capital ships. 

The higher speed doesn't guarantee survival in a conflict with Rome or the Norse, but it does reduce the time in range of hostile land-based airpower and at least makes surface interception a little more difficult. 

The armament has a bit more AA power, and the anti-surface components remain very much focused on the idea that the ship is running away when the guns are shooting.

Despite the faster speed, the ship has marginally more capacity, as a percentage of total normal displacement, as the smaller and slower oilers which preceded it.  Whether the Union springs for a lot of these more expensive auxiliaries remains to be seen.

[The Rock Doctor]

Since I laid down the oiler in 1931, I had to revise the engine year and then tweak the miscellaneous weights a bit.  10t less weight reserve and 20t less dry stores.

I'll tweak the light displacement and build costs when I do the 1/32 spreadsheet, so numbers in the 2/31 spreadsheet will be mildly inaccurate.

Enter ship name, Enter country Enter ship type laid down 1931
