As scout or trade protection cruisers not expected to duel with ships of equal force, I can see the light secondary outfit; if meant to screen task forces, it seems thin.

[SIZE=3]Redoubtable class, French Heavy Cruiser laid down 1943[/SIZE]
The two Redoubtable class heavy cruisers draw their existence from their immediate 20cm-gunned predecessor, the much larger Téméraire class. In 1940, the Marine Nationale ordered two examples of the class, complete with eight brand-new 200mm/L55 triple turrets, as well as eight barrels intended for installation as coast-defense batteries. Unfortunately, the second ship in the Téméraire class, with the proposed name of Sans Souci, was delayed until 1941 and then cancelled, leaving four completed triple turrets awaiting installation.
The Direction des constructions navales proposed several alternatives for a less-expensive 12x200mm-armed cruiser intended to use the spare turrets, but the French Naval Staff requested at least two ships in the class in order to justify design expenses. After several six-gun cruisers were rejected, DCN offered a novel compromise. Two cruisers would be laid down each carrying two of the triple 200mm/L55 turrets manufactured for the Sans Souci. The eight guns intended for coast defense batteries would be placed in twin turrets manufactured using parts from the 200mm twin turrets of the heavy cruiser Suffren (convered to an aircraft carrier in 1940) as well as the standard 152mm triple turrets. These twin turrets would superfire over the triples.
The two cruisers, laid down in 1943, were substantially less expensive than the Téméraire and Jean Bart class ships that immediately preceded them, being introduced under a period of fiscal restraint.

Mm, I suppose you're right, at that...
To be honest, with the various 150mm automatics being fielded or developed at the moment, I feel a bit of apathy about building more light cruisers at all, particularly in the 6" gun range. Combined with my general strong preference for 8" gunned cruisers, and the lack of a French 6" auto equivalent, I'm almost wondering if I might be better off downsizing even these ships and building 130mm-armed CLAAs.

Overall, the design doesn't look too bad. The block coefficient is within limits, though it does look a bit knife-edge to me, and I am not certain what to make of the caution remark. It's within the Gent's Rules for a small fast combatant, and would certainly thicken the AA defenses of the fleet.

Now the concern I have, though, is why I'd build a 3750-ton "light cruiser" when I'm building 2,500-ton Forbin-class destroyers - which have one less 130mm twin and one less 57mm AA gun. Three Forbins, at 7,500t, have more firepower (18x130mm, 18x57mm) than two of these CLAAs at 7500t (16x130mm + 16x57mm).
Three DDs and more guns, or two CLAAs? Um, easy choice - I'll go for the DDs.

Bit of a silly little idea; a coastal gunboat with 20cm guns intended for use as a coast bombardment vessel.

On the 8" cruiser front- I'm aware of the preference, and I have a soft spot for 3-2 2-3 designs, but waaaay back in the 1936ish Defense review I did, I came to the conclusion folks would stop building them, as the Clieto cruisers were already armored against them, I really thought you'd see more 9-10" ships for quick smashing power at maximum engagement ranges. So I'm curious why the French persist with them ?

If the French are faced with a 9-10" gunned ship, I have either carrier aircraft or the Dunkerques, which can put down an ACR like a truck running over a wayward puppy.

Hum! That's even lower than I'd have guessed just from looking about at things. What parameters did you use to define "light cruiser", if I might ask?
