Vilnius Union Ships, 1920+: Electric Drive Boogaloo

[Jefgte]

I like that kind of conversion.

;)

[The Rock Doctor]

An Aztec-style razee for trade defence and/or battleline scouting.  It might be overkill, of course.

I don't current have a 2-gun 300mm gun, but can change that in time for 1923.

I mean, I like them.

Though I've shifted from 6x11in to 9x9in with the newest class.  I'm banking on the Rate of Fire change helping.  Typically guns 10in and above have a rate of fire dropoff when compared to guns 8-10in. 

[The Rock Doctor]

Options for the next oiler program:

9,000 t light, 18 knots, 6080 t cargo

9,000 t light, 24 knots, 5230 t cargo

15,000 t light, 18 knots, 10500 t cargo

15,000 t light, 24 knots, 9550 t cargo

There is not a huge qualitative difference between the slow variants; the 15,000 t slow oiler is 67% larger and carries 72% more cargo.  Yippy skippy.

The difference shows a big more in the faster variant, where the big ship carries 82% more cargo.  I assume this is a matter of the larger hull being more favorable to the higher speed.

So the question then becomes what do I want out of the oiler.

On the one hand, the small, slow oiler is perfectly suitable for a World Cruise scenario where the Union is operating outside the Atlantic and its chain of bases.  So is the big, slow oiler but there's not a hugely compelling reason to have a big, slow oiler when a small, slow oiler does almost the same job and is less eggs in the basket and has easier drydocking requirements.

On the other hand, the fast variants are better suited to support Union squadrons running blockades around the British Isles.  With UNREP not far away, it's a potentially valuable asset as a means to avoid Roman or Norse fleets that might seek to hem in the Union navy during a war.  In this case, there is some argument for the increased efficiency of the big hull, but also the risk of it being a higher profile and extremely flammable target.

[Desertfox]

Option 1, don't put all your eggs in one basket.

[Jefgte]

Is it really necessary to have fast oilers to operate with cruisers ?

=> 9000t-18kts

[TacCovert4]

For Vilnius, I'd say no.  Aztec fast oilers exist primarily because when they were designed, running from Roman task forces was something in the cards. 

I'd say that rather than a high top speed, you want a high cruise speed.  A 14 or even 16kt cruise would allow your oiler to cover a lot of distance from a port with fuel to a fleet at sea.  Top speed is really irrelevant unless you're concerned about the oiler being directly hunted due to not having the ships to escort her.

[The Rock Doctor]

And the medium oiler in question.  As opposed to the recent 3,000 t oiler, this one does not feature an electric drive.  On the other hand, it carries much more oil, both for itself and for its clients.

It's one of the first designs to roll out the new 15mm/90cal machine-gun for local defensive functions, which is exciting.

Welcome back !

On the one Two up, the TDS beam is 26, the overall beam 30,
which means only a 2m deep TDS on either side.

The second one... well no TDS, no depth issues !

On belt sloping : " Main Belt inclined 16.00 degrees (positive = in)"
SS's weird, and makes you put -16 if you want it inclined out, rather than in.
I keep mucking it up, and in any battles, I will presume the belt is inclined
in the direction most useful :)

Interesting to view these and consider the Asawaran and Daphae
classes I've been tinkering with. as follow ups to the Zemakas.
Both more the 2nd size range, but a very different approach.

The 400mm seems to be relying on it's armored deck and speed,
but IMHO with a 30000+ ship, debatable. 

Consider substantial periods of poor weather,
nightime, then factor in the average
visibility range in the North Sea was ~12000m,
and that's where the Norse/Wilno/Rome play.

Even if you can pick the range, the immune space
may be very limited or non existent*, and be rather
far out... where with 6 guns and 1920s FC
hitting will be more difficult.

*navweaps for the 1918 US 14/45 mk 8, no immune zone.

[The Rock Doctor]

The 40cm ship is more a flight of fancy than anything serious at this point.  I was envisioning it more as something to hang out in the Caribbean than a North Sea presence.

Yeah, I have a consistent problem with the inclined belt thing - it's X degrees in the good direction, not the bad direction.

[TacCovert4]

Well, one of them is still a good direction, if you're sitting at 500m.......
