Although I intended to leave the French construction program pretty much as-is, we had a few realizations that caused me to make a number of slight changes to the construction schedule from 1941 onward. For one, I'd always known the French had a large quantity of older destroyers, and Agent and I discussed building replacements. Then I had a look at the numbers and suffered a minor panic; a large number of destroyers are pre-WWI, in fact, and needed replacements, pronto. In order to finance new vessels, I'm scrapping sixty old and small destroyers. In 1941, their replacements, the Sabre-class (aka "French Weapon"-class, or T41s) destroyers, will be laid down. The Sabres are basically modernized repeats of the earlier Jaguar-class destroyers. I've managed to wedge enough into the budget to be a fairly respectable force. Additionally, France will lay down a number of the larger Surcouf-class (T40) destroyers. (No, I am not wasting my tonnage on useless goliath cruiser submarines with mongo guns.) Like the Sabres, the Surcoufs are modernized versions of existing ships, in this case, the Le Fantasque class of 1933.

Meanwhile, the planned second pair of Bucentaure-class ships will be laid down. I couldn't resist tweaking the design a bit to try to save some money, but the ships actually turn out to be quite comparable in most respects. I had some difficulties with the names - I kept assigning names, and then discovered that another French ship had it already. But, after extensive research, I believe they will be named Vengeur and Pacificateur ("Avenger" and "Peacemaker").

In addition, the French Navy will reconstruct the Roland-class light cruisers. The first two ships to be refitted will be the two ships of the Djibouti Flotilla; but don't worry, they'll be replaced on that beat by the Duquesne and Glorie, at least until they've been refurbished.

Building on the foundation of the existing Caiman-class landing ships, the DCN has proposed the following design for keel-laying in 1941. While the Marine Nationale feels the Caiman-class has been a success, at the same time these vessels are hampered by their short range, and despite having good landing capabilities, smaller landing craft appear to offer better inshore performance. This has led to the interest in developing a long-range, highly seaworthy vessel capable of carrying smaller, lighter landing craft. An earlier DCN design study offered for Atlantean consideration was adopted and further developed for this role. The ship is designed with an aft well-deck which can be flooded to launch six tank landing craft (EDA-55 type).

I think the carrier is too large for her aircrew and wastes tonnage for speed too high. I also think her armament is too weak (number of main gun barrels) and her electronic equipment - all this radar and radar-guided fire control stuff - is too excessive for the time being (1941). In combination - tons of electronics to guide only 8 guns - the overall layout does not make sense to me. The 90mm gun lacks the range and altitude to compensate the lack of more 12cm barrels, methinks.

How do you calculate armored deck hang over, btw? And what is it good for?

Can you provide some overview how you plan to scrap 60+ DDs "pronto" and you will use the material gaines for the new building program? As I see it, it will take time (and free docks) to scrap all those units and gain the material, which than can only be spend two quarters later.

Why are you using 530mm torps on the Rolands but 550mm on all other designs?

Hm, well, I think the carrier is just about the right size, myself. The speed is a function of matching the speed of other modern French carriers, and having that speed provides another precious few knots worth of lift for aircraft.

Simmed a 30mm armoured deck and took the figure derived for the weight of that armour, then used it in miscellaneous weight.

The Arabe and Bisson-class destroyers started scrapping in Q3, as is demonstrated in my reports. In any case, I require replacements "pronto" - I am in no such hurry to scrap the ships.

The original ships had 530mm torpedoes and I forgot to change them to 550mm in the rebuild. Thanks for noticing that, I'll correct it.

Corrected Rolands.

As to the value of the armoured roof over the hangar deck, it is in fact an armoured flight deck and helps to protect the hangar space itself from bombs, much like the OTL British carriers of the Illustrious and Indefatigable classes. I see that as being beneficial if it keeps the aircraft carrier operational.

I would site the trouble that the Brits had with fixing said CVs after the hangers were deformed by bomb blasts as reason against it, but as we have had no experence with such a thing yet it is sort of a moot point.

I think I would prefer to have a carrier to repair rather than one that was sunk. However, as you say, we are presently dealing in the theoretical rather than the practical.

I am curious as to whether you envision this as a fleet tug, a rescue/salvage tug or some other specialist purpose?

It looks as though the basic hull could be customized depending upon need.

Something of a small seagoing salvage tug, I imagine; something with enough power to move a damaged cruiser at sea, for instance. I do feel a bit that the Sologne-class is falling between two stools - not small and nimble enough for harbour work, but then not large enough to serve as a full fleet tug.

French carrier design keeps the hanger floor as the strength deck, not the flight deck as in the British carriers.

Still, I did sim this alternate Vengeur with a single armour deck, rather than splitting it. In light of the odd comments about the dislike of the main battery, I made some alterations.

Ships in Class:
- Vengeur
- Indomptable

After some consideration, I think I'm going to adopt the second version of Vengeur, with the single armoured deck rather than the split one. I'm still not sure about the all-120mm armament, though it does probably make more sense according to my design calculus.

I must admit I'm surprised no one called me out about sticking a helicopter flight deck on the Châteaurenault design. Alas.

Here's a design without the helos - and the one more likely to be adopted. (Despite the apparent lack of protest! )
