The 2 Valeur Class battleships, also called semi dreadnaughts, are ready for at least an overhaul.

But, are the ships themselfs good enough? 
Only 17.5 Ktons, main armament 6 340mm guns.  Armor 11"  only 20 Kts.

Oh well. 
An refit.
Removal of all tertiary and quartiary armament, and replacement with a 6 AA guns.
Adding of Fire control, ERADe and Marconi equipment.
10% oil firing for a sleight increase in range.

Could probably replace the end belts w/ thinner ones now that range of battle has increased sufficiently. I'd say 3.5-4" should be thick enough. Use the extra weight to do whatever with

I think a minimal refit of replacement of the 3rd and 4th batteries with something modern and useful and oil firing is fine. For a nation more pressed for capital ships (like the CSA) something more radical might be called for, but for France, just keeping them up to date is probably enough.

You've heard my views on the 195mm gun before... Replacing that with something less unwieldy and with a higher rate of fire might also be a worthwhile exercise.

This more interesting then?

Refit 1916
Secundary armament of 6 twin 195's changed for a new to build tripple 140mm turret.
all the rest is plated over, removed and exchanged for 6 37mm AA guns.
Magazine layout for main guns changed, 10 more shells per gun carried.

Draught reduced and freeboard increased with .3m
Trim changed to the new setting.
The increased seakeeping ability will keep these 2 ships at their current posting. French Canada.

That's what I would wrote  :D
Remove the 195mm & install 140mm better against TBs

QuoteSeaboat quality  (Average = 1.00): 1,52
you could perhaps change the engine & increase the speed to 22kts

To expensive.  I prefer to build a new ship with a better-longer hullform then.



maddox

Scrapping the ships and retain the guns and turrets for other applications is an option.

If only the 340mm and 195mm turrets are retained, the scrap value of these overgunned semi BB's still is $2,5 and 2.5BP .

The 195mm turrets could be used for a cruiser, and the 340mm turrets for a BC.
Or both for coastal defences.


An overhaul will cost Glorious France $1.75, but will leave 2 seaworthy, overgunned, slow semi BB's.

But a refit the ship, like removing all the small guns,  will cost at the same and gives 95 tons of misc weight in place.-and that's counting on the removal of the 105mm casemated guns.

A more extensive refurbisment like the latest proposal, will cost $5 and .5BP.
Re-engine the ship, like Jef proposes, and going 100% oil fired will add $5 and 2.5 BP (and that's with the scrap value discount)

But then it stays a semi dreadnaught with a rubbish gun lay out.

The Rock Doctor

They're decent enough hulls for station command functions in places like French Polynesia.  First generation dreadnoughts would be challenged to defeat them once modernized. 

maddox

The 11" belt and the 2" deck argue against that.  These ships, on their own are BB bait. And even together the Valeurs ain't worth 1 Bretagne.

But, just a new layer of paint, making sure all the greasenipples are worked over, and they can do the task for another decade.
Their task currently, North west Atlantic flagholder. More friendlier waters for france ain't to be found- if you discount the weather-

P3D

Upgrade and installing FC is a must if you want to keep them in service. As France is willing to buy Russian PDNs of even less belt. Converting to oil firing might not be crucial, swapping the whole engine would be waste of money for 1.5 knots gain.
The first purpose of a warship is to remain afloat. Anon.

Borys

Ahoj!
I'd give them FC and that's it. Powerful station ships. Preferrably used together.

NEDS - Not Enough Deck Space for all those guns and torpedos;
Bambi must DIE!

maddox

Giving them FC- what is of limited use, because all those turrets and casemated guns are in each others firing angle- would mean I need to find 250 tons somewere.

The only way to do that is to remove a lot of guns. And even then. (Like calculated, only 95 tons in that operation.)

So, the best thing I could do, if I want to retain the ships, is toroughly modernise them.
For that money and BP, I can build a Demarce.

I can replace those 2 semi dreadnaughts with 6 Demarce IIIb's or even a further elaboration of that class.
