FAN Voltaire (SD) & Danton (BB) - 1909 + mods
Back to French Navy page
29/11/2023 - I get quite harsh with the French Navy
over these ships. I can look at it from the other side that they needed to
complete some battleships as soon as possible because they were falling behind
both the German and Royal Navies. But building second class ships was not going
to help their cause. (new drawings available too.) Read on!
The Danton class never made any sense to me. One ship maybe, too far advanced
to cancel, but six?? absolutely ludicrous. I could understand it better if the
ships had been started being built before Dreadnought was laid down and built.
But Dreadnought was built and completed by 10/1906. The first of the Danton's had
been laid down about the same time the second over 6 months later, after that
there is absolutely no reason for the remainder to have any chance of being
completed under their original plans. The first two laid down are actually
Condorcet and Voltaire, with Voltaire being the earliest. Diderot was next after
that, then the other three. To me that will make the early semi-dreadnoughts the
Voltaire class and the later four Dreadnoughts, the Danton class.
As a semi-dreadnought, armed with four 12" and twelve 9.4", they were as good
as any other in the world. But from the moment the Dreadnought is completed the
Danton's are no longer looking so good. A simple rearrangement of the main guns,
the deletion of the 9.4", would have made a large difference in the ships
capabilities. I complete the first two to the original semi-Dreadnought design.
After that I have two streams in mind. Go to a wing turret design with six twin
turrets, with one forward and aft and the other four on the wings of the ship.
This would give a broadside of eight guns. Equivalent to the Dreadnought and
Nassau classes.
The dimensions did not need to change just the layout of the main guns. The
Danton sub-class would have had the same broadside as the Dreadnought and
other first battleship classes and would have paved the way for the larger Provence class 12" battleships that followed. One of the good things about the
class was the turbine machinery that was fitted to all members. It is much
easier to maintain a higher speed with turbines than is possible with the
previous triple-expansion machinery. I have always seen the early dreadnoughts
as conservative efforts. All of the worlds navies had the South Carolina as a
template to plan from. What was so good about the design? It only required four
turrets to provide the same broadside as the echelon/wing turret designs. A two
turret saving is actually huge in terms of production. If the French use the
wing design for these ships, then they need twenty four twin 12" turrets. That
same twenty four turrets could provide the main armament for six ships. Using
the inline version, it is easy to see the next Courbet class as a step up. Did I
say I hate those horrible turrets?
The ships had a busy WW1 with the six battleships being used to help patrol the
Adriatic Sea against the Austro-Hungarian Fleet, and also later the ships were
active at Gallipoli while two were stationed at the mouth of the Dardanelles to
guard against a breakout by the Goeben. The Danton spent its time on convoy
escort and was torpedoed by a U-boat in 03/1917 off Sardinia. The Mirabeau ran
aground near the Crimea during the White Revolution in which the British and
French tried to help restore the Russian Monarchy back into power. The ship was
badly damaged and while the ship was salvaged and returned to France the hull
had been warped and the ship was decommissioned and used as an accommodation hulk
at Toulon. Which leaves four left to turn into miscellaneous vessels. Two
Semi-dreadnoughts and two battleships.
The restrictions of The Washington Treaty meant that remaining four ships
were excess to requirements once the French Navy had received its share of the
ex-German Fleet. The ex-German ships were far superior to the remaining
vessels and there was no contest as to which ships would have to be
decommissioned into ancillary duties. With the completion of the Guynemer and
Languedoc in 1928 the Voltaire and Condorcet were taken in hand for rebuilding
to lesser duties.
The Voltaire became the French Navies catapult trials ship and ended up as
what the British eventually termed an Area Defence Vessel, a large hangar and
catapult replacing the rear guns and machinery of the ship. Maximum speed with
half the boilers removed fell to 14 knots. There were a lot of harbours along
the French African coast line and even Madagascar and Tahiti where an Area
Defence Vessel would be invaluable.
Condorcet was the trials ship for the new 5.1" gun systems and a quadruple
turret and two twins replaced the twin 12" and the pair of twin 9.4" at the rear of the ship.
The new 100mm twin and single mounts were also mounted aft. Plenty
of light AA weapons made a very useful mobile AA platform. Maximum speed with
half the boilers removed fell to 14 knots. On the outbreak of war, the main
French Naval base is Brest and that is where the Condorcet is stationed as extra
AA support. On the 1st of July 1940, with surrender imminent, the Condorcet is
ordered to Mers-el-Kebir as the major AA ship for the base.
The Vergniaud and Diderot became training ships. They were to have been
demilitarised but the failure of the 1930 London Naval Treaty reprieved these
two ships. The major class of vessel that France could do with many more of is
the Trade Protection Cruiser. What was needed was to increase the range, which
was accomplished by removing the 5.5" guns and magazines, and replacing the
magazines with extra fuel tanks. Where the guns had been was plated in and
converted to extra accommodation. The old coal fired boilers were removed and
replaced with oil fired ones. The coal stowage being converted to oil bunkers.
The five funnels could then be replaced with two. What the French got was two
ships that could act as convoy escorts through those areas where Germanic States
raiders might prey on them. Then as patrol ships on the long trade routes trying
to run down the merchant raiders that were a thorn in the Allied sides.
1940 and the ships escaped from Brest to UK ports. With other French ships,
these two were boarded by Commonwealth troops and made 'safe'. The crews aboard
the ships were given the option of joining the "Free" French and manning their
ships against the Germans. Most joined, those that did not, were interned. Both
these ships were operated out of Liverpool as convoy 'heavy' escorts. Both ships
survived the war and were used for two years repatriating troops and equipment
back to France. Both were struck from the Navy list in 1947 and sold for
scrapping.

France had all the twin 12" turrets removed from these ships, which were to old fashioned to be used for building more modern ships but these turrets were ideal for use in fortified positions (about half ended up in the Maginot Line) and as shore batteries protecting French Naval bases.

These old drawings held a lot of merit and showed what could be done with the
old ships. A lot of French ships went well past their use by dates because they
had no 'intermediate' ships to draw on from those that had been completed during
the war, which a lot of other countries did have. These drawings are also well
past their use by date.
