Some Imperial Russian warships

[Tzoli]

Either a very early CODLOS (Combined Diesel-Electric or Steam), Turbo-Electirc and Diesel or Turbo-Electric and Diesel-Electric where the electric engiens were run either on Diesel or on Steam Power.
It could be done but either the steam plant is moving the ship or the Diesel but this early not both.

There is no particular limitation in using both diesel and steam turbine as generators for electric motors. To have reliable and powerful diesel and electric engines this early could be difficult but once you have to combine both with a steam plant present no technical challenge.

 

[Tzoli]

for electric propulsion yes but if you want to propel the same shaft with two different engines then that is the problematic. But yes the mention of steam and electric drive implies Turbo-Electric propulsion with an added extra Diesel element, still to reach this range you require extreme oil storage. The drawing shows a 3 shaft arrangement with what looks like to be two steam turbines, 3-6 diesel engines and likely 3 electric motors.

 

[Dilandu]

That range... Isn't it a typo??? Wouldn't it be more like 4,950nm? 49.500nm is 91.674km!!! Which is basically equals to today's nuclear propulsion vessels!

It's diesel (or diesel & turbine) powered, and there were a bit of... overoptimistic assumptions about diesel performance in 1900s.

"Armoured cruiser" project:

View attachment 668884
View attachment 668882
View attachment 668883
24 000 ton, 648x80x27 ft, 6x2x10", 20x120 mm, 42 860 hp, 24 knots, range with 11 knots - 49 500 miles, operating time at sea with 11 knots - 187 days, there are kite balloons, two 8-ton submarines and a 25-ton torpedo boat. Armour - more than "Andrey Pervozvanniy" (8.5" belt, 5" casemate, 10" turrets).

From when dates this armoured cruiser project. I suppose after 1911?

3 Diesel and 2 turbines or 3 turbines?

3 Diesel and 2 turbines or 3 turbines?

Incoherent. On scheme, turbines and electric motors are mentioned. In text, diesels and boilers are mentioned.

My interpretation is that authors meant this:

* Combined powerplant with electric transmission
* Diesel engines for cruising on 11 knot speed
* Steam turbines for 20-27 knot speed

The range is set as "50000 miles, or 180 days of cruising on 11-knot speed on diesels, while simultaneously maintaining enough pressure in boilers to immediately switch to 20-knot turbine speed if required" . Authors specified the demand to make runs from Murmansk to Vladivostok without need to refuel, and having enough fuel reserves for speed dashes (chasing enemy merchants or fleeing from enemy cruisers). On steam alone, range is declared enough to cross Pacific (from Vladivostok to San-Francisco) or Atlantic (from Murmansk to New-York) on 24-knot speed.

Max speed is set as "no less than modern British cruisers have". Authors elaborate, that if they took into account only commissioned ships, then 25-knot max speed is deemed enough, but if the building "Inflexible"-class cruisers (and unspecified new Japanese cruisers) are considered, then 27-knot max speed is required.

Ah, is the book about Russian's giant warships, i don't think there's english translation of this (unless am wrong), you can use DeepL to get a better translation than google, not 100% perfect but workable.

I knew I had seen the cover illustration somewhere...(excerpt, obviously from this publication)

 

[Pirate Pete]

I found this in my 'archive' of old files and downloads.
It comes from an edition of 'Warship', when it was issued as a quarterly periodical...

 

[Cormallen]

It looks rather reminiscent of that well known "Junkers Diesel Battleship" so maybe that inspired the long range ambitions?

 

[190X]

Sorry to resurrect an old thread, but I thought it might be a good place to ask if anyone has any information on Vickers' Dreadnought battleship Design No. 318, as nearly accepted by the Russian Naval Ministry in late 1907, particularly '318e' variant of the design with superimposed turrets.

I'm aware of the general background to the design, and of the illustration in McLaughlin's Soviet and Russian Battleships. Even just the dimensions of the ship would be fantastic.

 

[Tzoli]

Vickers Design for Russia / Vickers Design 318 from 1907
Dimensions: 155,50(pp) x 25,30 x 7,77m
Spedd: 39km/h
Engines: 26.000shp 4- shafts
Likely 18x Yarrow boilers
Vertical Triple Expansion engines (likely Yarrow)
Armour: 203mm belt
Displacement: 20.200tons
Armament:
4x3 305mm/50 Vickers Mk C
8x2 120mm/50 Vickers Mk A
2x1 457mm Torpedo Tubes

There is a Design 318E but the data seems to be the same.

8 x 12 " (2 x 2 and 4 x 1), and 20 (?) x 120 mm guns

[Tzoli]

Vickers to Russia - battleship/battlecruiser, 8 x 16" (?) guns:View attachment 696799

According to Friedman it was also offered to Brazil but with only 10x 6" guns and a displacement of 28.950tons
Dimensions: 184,4(pp) x 28,65 x 8,7m
60.000shp 4 shafts
12" Belt 1" deck armour and likely 1,5" slopes.

Your drawing shows a distinct QE/Revenge inspiration which confirms my theory that the Vickers design offers (646/A, 647/A) to Japan which inspired the Nagato were also of QE lookalikes.

Russian battleship Chesma (1886) - Wikipedia

The battleship Chesma was due to be upgraded into a classic pre-dred, but it was cancelled

 

[190X]

8 x 12 " (2 x 2 and 4 x 1), and 20 (?) x 120 mm guns

Does anybody have more on this unusual design?

 

[Dilandu]

Does anybody have more on this unusual design?

It was a 10.000-ton coastal battleship, presented by engineer G. Ahenbah for a design contest of Russian Engineering Society in 1905. The goal was a small coast defense battleship, armed with ten 12-inch guns. The model on the photo was supposed to have three dual 12-inch turrets - two superfiring on bow, one on stern - and four 12-inch guns in casemates. For some reason, the rear turret is missing on model (one theory is, Ahenbah realized too late that his calculations are wrong, and removed rear turret to make ship lighter. The other theory is that model was just accidentally damaged before photo).

The Ahenbah model took a first prize, which is written on plaques beneath it. Of course no additional works were done; it was merely an engineering contest of original ideas, not actual navy designs proposal.

P.S. The Chernikov reconstruction of Ahenbah battleship here -



- most likely is not correct.

 

[Tzoli]

I've seen once a drawing of a similar battleship with casemated 12" guns a few years ago.
I think it was the Imperial Technical Society Design 1906 - 112,5 x 21 x 6,8m 10500tons, 28km/h, 2x2,4x1 305mm, 20x1 120mm, 2x1 457mm Torpedoes, from 1906.
It could had been this proposal.

Seems that it's from the same design competition. At least displacement, speed and main armament fits the competition goals.
