French defeat of June 1940 explained (partly) by "bureaucratic viscosity" (revised 08 / 07 / 2020 *)

Viscosity is a physical property which is defined by two simultaneous trends: One being a withstanding to any movement, the other being to invade all surfaces. 
For example, engine oil displays a strong viscosity.  

"Bureaucratic viscosity" is a property of any kind of administration to stop any positive evolution.



The problem of the Armée de l'Air aircraft fuel



In 1937-1938,  French Armée de l'Air standardized Hispano-Suiza 12 Y 31 engine, at the very moment of same company proposed the clearly better HS 12 Y 29 engine for fighters, yielding 60 hp more until a 350 m higher altitude

For a Morane 406, the new engine allowed 480 kph at 4.800 m instead of 455 kph.
For a Nieuport 161 of 1938, it would allow up to 520 kph...

The reason was refusing to use 100° octane fuel (with TEL) needed by HS 12 Y 29, a bit more expensive than 85° fuel used by land forces.


Another idea was standardizing of military aircrafts, to obtain only one fighter, only one bomber and only one recce aircraft.

Germany followed same way with the Messerschmitt 109, a very good fighter.
It was successful until Barbarossa. She was irrelevant in Russia since September 1941, because she was to lightly built to withstand both general environmental conditions as, also, strong AA fire. For USSR front, the FW 190 was clearly more suited.

Considering French Air Force, if  Morane 405 was as good as the CEMA reports told us, a true order (at least 50 aircrafts) given quickly in March 1936 would provide a first and useful experiment of modern aircrafts to French pilots as also to all French military components. 

The actual price was less than FF 1,000,000. Such an order did not necessarily freeze any following orders for other more efficient fighters.

If another competitor - e.g. the Nieuport 161 - displayed clearly better performances, it was absolutely normal and necessary to order it in larger amount. 

For a fighter, the performances are the key of efficiency.

For any Air ministry administration, it would have been only a capability of quick adaptability when facing a given situation...

Knowing the two clever orders for both the Hurricane and the Spitfire at the end of 1936, Yes, I'm jealous, even being not a fan of the slow (but reliable) Hawker fighter (but a fan of the Gloster No name - F/34-). 

Nevertheless, the British policy is not so clear that it appeared in historical textbooks, because the Spitfire entered very late in production (may you explain me why, during the same duration, 1000 machines of the all metallic monocoque Fairey Battle bomber were built against only 200 Spitfire?)


The only one "successful" fighter of the Morane-Saulnier company was the former MS 225 radial engined (1932). 
This success resulted from two major breakthroughs: The supercharger and the NACA cowling, which together allowed this fighter to achieve 330 kph (in it initial variant, she could fly at most at 260 kph. 
Never confronted with high speed air planes, the Morane-Saulnier engineers had never experienced powerful engines, nor their huge cooling difficulties. 

They were no more aware of the constant need to discover all the little aerodynamics gains which made the difference between the outstanding aircrafts and the common ones.

Then, they abandoned their own power of decision to the members of so-called "technical" committees

Indeed, the persons involved in these committees did not detect the multiple aerodynamic faults affecting that plane.

They imposed - to establish their 'credentials' with the Army - the drum-fed MAC 1934 machine guns with only 300 rounds each, instead of the cheaper, lighter belt-fed Darne 1933 machine gun.

The new MG was not adapted to be embedded in the thin wings of a fighter where it induced a bulbous excrescence on the leading edge of both wings costing the loss of several precious kph... 

The same persons accepted the aberrant, totally inefficient, heavy 
and retractable radiator which also costed, at least, 20 kph.




The sad story of the Dewoitine D.520 


At the end of 1934, Emile Dewoitine, deceived by the German Propaganda, had conceived his D 513 fighter from Heinkel 70 seen at Paris Air Show 1934.
He did not know the part of the exceptional finish in performances of this aircraft.

The tests had quickly demonstrated that it was a bad idea,  stability being problematic, top speed of D 513 limited to 425 kph for months, and she never exceed 445 kph (but climb speed was good). 

However, Emile Dewoitine, an exceptional aircraft maker, understanding his error, tried to stop the developing of the D 513 and, since the end of 1936, started designing a completely new fighter which became the successful D 520

It was moment of a new "bureaucratic viscosity" manifestation stopped this new fighter.

The so-called "experts" were convinced D 513 may be perfected, becoming stable... 
The complete 1937 year was spent to a lot of secondary works. 

May be, awaken by the high performances of the Bf 109 at Zurich meeting in 1937, Ministère de l'Air ordered 2 prototypes of D.520 (April 8, 1938).


The drawings being ready, the work proceeded quickly and the D.520 took off the 2 of October, 1938, showing excellent flying qualities. 

After some minor refinements, the fighter demonstrate her excellent maneuverability, a very good top speed and a very good climbing ability.

 An order was given for 200 Dewoitine D.520.

Ordered in the Spring of 1937, the new Dewoitine fighter will be in Armée de l'Air in significant amount since 1938 Summer.

That could have given a completely new situation.




About tanks and fighter-bombers



In the review GBM, Mr. Stéphane Ferrard wrote that Louis Renault proposed, in December 1936, his G1R tank, a revolutionary one, with a 75 mm L/29 in a rather flat quasi-turret. 

A speed of 40 kph was expected on the road and 20 kph on the field. The range was 200 km and the armor was 60 mm thick. 
  




Renault G1r (or ACK 1) - An impressive tank of very advanced design


As usual, Infantry Commission was stunned! So,new theoretic studies were needed(?). 


Please, compare this 1936 tank with M4 Sherman of 1944. G1R is more similar to the T 62 Russian tank.

 mm gunThe first prototype was ordered in May 1940 with a 75 mm/29 cal. gun, three full years too late. 
Ordered in 1937, the mass production could have be initiated in 1939, giving a clear advantage to the French Army.

I'm going back to the aircraft.

In 1939, the diminutive Roussel R 30 single seat fighter prototype flew for the first time
Her performances were interesting, with an impressive climb speed (19 m/s) and a top speed of the same order of magnitude than last variant of the Bloch 152, with a GR 14 Mars yielding only 700 hp.

She carried two 20 mm canons (likely the rather weak Oerlikon MG FF) and also one 250 kg bomb which appeared a bit heavy for a fighter with a wing area of only 10 square meters and a take off weight of 1750 kg.

About at the same moment, General Vuillemin rejected LN 411 ground strike fighter-bombers he had previously ordered.

Such fighter bomber using a so heavy bomb suggests to today observers that the Bloch 151 were most appropriate for such a task. 

These fighters were toughest than most of other ground support Allied aircraft, and their wings totaled 17 m². They were able to fly at 460 kph, a speed easy to boost by 15 kph with exhaust pipes.  

The French Air Force had more than 100 of these fighters but did not used these fighters to strike the armored German divisions.

Much more robust and fast than the MS 406 of the GC I/6, they would had more success and less casualties.

May be, there was no communication between his different offices? It's another form of the "bureaucratic viscosity".





The Tyranny of the commissions




The "bureaucratic viscosity" is issued mainly from stacking of many commissions, each of them wanting to examine every decision.

Each examination follow a complicated formal procedure taking a lot of time. 
These procedures do not follow any scientific law. 

This stacking result always in standstill.

If a man like Charles De Gaulle arise, he was seen as sacrilegious, before to be excluded and, even, sentenced to death.

From the "national pants" to the battleships, the lethal wedding (for French soldiers) between lobbies and news papers before both WW I and WW II (revised 11 / 08 / 2014)


Democracy and Truth must be ever linked together


Democracy is the best possible form of government, yes, it's absolutely my own conviction. 
However, a democratic power implies some constraints, one of them being the obligation to say the Truth. 

And, as the History teach us, it's not always the case.

Today, at the first part of the XXI th century, it's usual to underline the paramount role of the media. 

And, whatever say the journalists about that subject, their power is real. 

Very often, their writing 
goal is to influence large part of the opinion.

Those who use unverified informations may destroy the very basis of the democracy: All ill-based decisions became catastrophic, and disasters may happen quickly, as it occurred for France at least twice.




The French "national pants" affair induced huge casualties at the beginning of WW I


(source: Pierre Servent, Le complexe de l'Autruche, Perrin ed.)

This story occurred more than a century ago, in the 1911 France.

Since dozen of years, French infantrymen wear red pants (in French, that variant of red color was named as garance).



Personal document of the author -  The French soldiers were perfect targets for their German ennemies.
Seven years after the publishing of this picture the German gunners found that dressing very fun!


The French minister of War, Adolfe Messimy, knowing clearly the evolution of the military clothing since the 1st Boer War (1881), wished to change the field uniform. 

During the Boer War, the khaki clothes worn by the Boers farmers allowed them to shot down their British enemies with a kill ratio of about ten British for one Boer because the British professional soldiers cannot see them in the bush. 

The British soldiers wore flashy red uniforms giving perfect targets to the Boers...

The excellent French minister (I'm not used to write such compliments for a minister of my own Nation) launched tests on the field with réséda colored (~khaki) uniforms, during the Fall maneuvers in 1911.

(The excellent French review GBM (Guerre, Blindés, Matériels) had published a good paper and especially good painting on this subject in his #102 of 2012)

The newspapers expressed how they were unduly indignant: "The great republican principles were not respected, our soldiers became ridiculous, the officers would lose all their authority, the red pants were so much fun," and so on....

These articles were passed on by the members of parliament.

Though, one could be aware at this time that, if the Lebel rifle had good range and accuracy, the reloading of its magazine was very slow by comparison to the German riffle. 

The common sense would have been to equip the French soldiers with more drab clothing which would force the German soldiers to advance closer to the French lines to be able to engage them. 

So, the live losses would have been much more evenly distributed between the two opposite camps.

It had constituted somewhat like an actual stealthiness.

A similar political reaction happened simultaneously against the steel helmet, which equipped the French soldiers as late as September 1915 (a full year wasted).

The official reason then given was it was anesthetic!

It resulted that 300,000 French soldiers were killed and 600,000 wounded in the first 3 months of the war, among them  210,000 perished between the first day of the WW I and the end of the first Battle of the Marne.


The lesson is that, in France (at least?) politics follows often a lot of theatrical gestures which have nothing to do with the real world.

The problem is not really the political opinions of journalists, but their articles - as those of scientists - must be absolutely based on the Truth

If they had followed such a principle, numerous French soldiers would have been uninjured and more German soldiers were killed in the beginning of the WW I.



Lobbying for battleships, in 1936!



My purpose is to explain how the IIIrd Republic wasted its own maeger budgets into military foolish and irrelevant spending.

The following picture displays an article in a French review  rather similar to  Popular Science  and published at the end of 1936.



Personal document of the author 


In this article, the author discussed the budget of the French Navy for 1937.

The title was clear: The Navy had ordered 51 ships, but a single battleship would be more relevant...

The author wrote how insignificant would be the anti-submarine, the logistic boats, the submarine and the patrolers ordered.

View from today, it's ironic, knowing the weak role of the French battleships (as the battleships of all other countries) and the huge role of submarines, patrolers, logistic boats in WW II.

He is crying how weak the French "battle-group" would be with only two battle-cruisers and two battleships.

This writer was likely a man of the admiral Darlan stable.

The Front Populaire (a politician leftist coalition including the parliamentary support of the communists) was actually steering France and had launched a lot of reforms among them some were necessary - but very late - and some other were completely irrelevant (e.g. the nationalizations).

One of the consequence of that policy was huge spending, so the military budgets could not be as important as it was needed to answer to Hitler's Germany powerful arm race.



Hitler, the only real threat for France


Hitler, at this very time, had occupied the left rim of the Rhine, and also he developed a strong armored army, a strong AA artillery, a strong Air Force and a strong submarine fleet.

The worst enemy of the IIIrd Reich, as Hitler expressed in his program (Mein Kampf), was France, and there was no sea between France and Germany.

Our Navy had no mean to interfere efficiently with Germany in case of war.

It had no operational landing craft (I've read some years ago experiments were in progress with only two vessel of 60 and 90 tonnes).

The French Navy was conceived only to secure the naval traffic between France metropolis and its colonies, especially the North African ones.



The naval and colonial lobbies in action


The writer of this article began his narrative by the proposition which he prefer (we need battleships) before to write an apparently opposite opinion (aircraft may endanger the battleship). 

However, it was only a formal concession.

Four battleship were soon commissioned or very advanced but the writer wanted a battle group of nine battleships for 1943.

In the 1937 FF, the price of each of these battleships was 2,500,000,000 FF. 

With this money, France was able to buy 2,000 Dewoitine 520 or 1,000 Spitfire!

The huge amount of armor steel needed for these naval behemoths were useful for the bunker of the Maginot line near Sedan as they were useful to the tank industry.


For the French Navy, as for most of the other ones, the Aviation was seen as a great threat.

The Armée de l'Air was obviously money consuming.

The French Navy was addict to money, as all kind of great administration in all countries.

Though, it got 42% of the military budget from 1926 until 1936.

The top leaders of the Royale had not the vista which may allowed them to anticipate the near futur, except a handful as Frochot (dead in 1929) or de Laborde (whose stupid decision to scuttle the French Fleet at Toulon in 1942 - instead of joining De Gaulle - was only related to his very bad relationships with Darlan). 

They had not understood the clear lessons of the Battle of Jutland were it was obvious that the battleships were completely useless. 

Indeed, even if they were well conceived, they cannot conclude their actions.

When they were ill-conceived, as were all the British battle-cruisers, they exploded with all hands (as it was again the case in 1941 with the HMS Hood).

Instead, they would be wise to develop sonars, radars, anti-submarine warfare, and aircraft carriers. They do not... except to late.


They privileged flying boats, easy preys for any land or carrier based fighters.


Even for their submarines, the French admirals wanted a strong artillery, noisy when submerged, as also powerful surface engines in order to follow the fleets!

The consequence was the fine submarines dubbed "1500 tonnes" of the Redoutable class may be heard when they were surfaced at 12 nautical miles far from the coasts (source: Captain J. L'Herminier, Casabianca, who must be very skilled to conduct a lot of secret missions in Southern France and Corsica coasts).


The French Air Force obtained the first part of the military budget only in 1939, too late...

A free press is essential to Democracy, but the problem remaining is the sense of free.

Lobbies and bribery are often linked, then both act together against Liberty and Democracy.

The Loire 210, obsolete? Yes, but she could had been so useful for the Campaign of Norway... (Upgraded 01 / 26 / 2020)


(Sources : A good paper on the Loire 210 fighter by Gérard Bousquet published in AirMagazine n° 57 in February 2013
the Hors-Série #1 of Avions, 1994, by Lucien Morareau, absolute master author on the French Aeronavale history, who also published two more recent papers in Avions # 197 and # 198 on the Loire 210, in  2014, 
and some other sources, like the tiny Floatplanes #6 of William Green)



What kind of Air Cover for the French Navy ?


I had already written the big problem of the French fleets (click here) in almost all the seas or oceans they were involved: Once some hundreds of kilometers away from friendly coasts, they were defenseless against any aerial threats.

Remember that the Washington treaty on naval forces allowed only 60,000 tw of aircraft carriers to the French Navy. 

France had two carriers in the 30's (totaling about 30,000 tw). 

The Béarn was a rather classical aircraft carrier, able to carry at most 40 aircrafts, but she was plagued by an over-complicated system of lifts, these lifts were protected by armored doors (!), all implying too slow hoists in the aircraft hangar and which were very time consuming during military actions.

The other French carrier was the little seaplane carrier Commandant Teste, able to carry 26 sea planes with 4 catapults and five cranes.
The lay out of this boat was sufficiently good to be copied by the Imperial Japanese Navy.


From the other hand, the recent battleships, the cruisers and even some colonial patrollers had catapults to put seaplanes in the air.

Most of these seaplanes were only scout planes, some times with a limited bombing capacity (one or two 75 kg bombs).  


In 1931, the admiral-to-be Lartigue had, very logically, taking into account this poor amount of aircraft carriers, expressed the need of a complement of air cover of the French fleets by seaplane fighters. 


In some post-WW II influential publications, you may read that such an idea was already obsolete. 

Nevertheless, many naval countries have tested seaplane fighters from the end of the 30's to the beginning of the 50's: 

  • In Great Britain, the Blackburn Roc was transformed in hydro-fighter, a very strange idea, knowing the definitively bad aerodynamics of the carrier based Roc. Her top speed was 270 kph.
  • After that, a Grumman Martlet was fitted with float. That was clearly better.
  • But an undoubtedly greater success was obtained in September 1941, when a Spitfire Mk V was successfully transformed in a really good floatplane fighter (top speed 520 kph and climbing to 8,000 m in 12' 20") - three were ordered by the Royal Navy - as one of them was transformed, a bit later, a Spitfire Mk IX (610 kph).





A splendid picture of a Spitfire Mk IX on this site (610 kph !)



  • The Imperial Japanese Navy proceeded similarly with the Zero A6 M2-N able to fly at 435 kph and to climb at 5,000 m in less than 7 minutesThe today narrative is this aircraft was unsuccessful, but 327 machines were built with good tactical results!
  • They developed also the exceptional float plane Kawanishi N1K1 Kyofu, able to fly at 490 kph, to climb to 4,000 m in 4' 11" (97 machines were built, too late).


In all cases, such fighters could have been available to cover their fleets against enemy bombers as they were able to land on any water surfaces, because nobody can destroy such kind of "airfields"


Moreover, this idea revived at the end of the WW II with two jet fighters. 




 Saunders-Roe SR.A/1 - A very good aircraft.

The first one was the British Saunders-Roe SR.A/1, conceived during WW II, flying successfully from 1947 to 1951, but she was abandoned after the withdrawal of the engines manufacturer... 

Another hydro-fighter was build in the USA, the Convair F2Y Sea DartShe was under-powered but flew faster (high subsonic). 

Unfortunately for the concept, she was flown after the victory of the supporters of the giant aircraft carriers. 

Some interesting French projects were also submitted actually by Latécoère but none of them was accepted.



The wishes of the French Navy in the 30's


A program was published by the French Navy in 1933, 2 years after the study of Lartigue (!), and specifying:
  • A speed of at least 300 kph at an altitude of 3,500 m,
  • A maximum weight not exceeding 2,000 kg, in order to be launched by the existing compressed-air catapults,
  • The altitude of 3,500 m must be reached in less than 12 minutes,
  • The engine chosen was the Hispano-Suiza 9 V providing 700 hp and actually seen as very reliable, as they powered the tri-engined Dewoitine passenger airliners,
  • A fabric covering of the structure at the very moment of the triumph of the stressed skin! It was likely a colonial point of view, as the need to prepare the maintenance with easily available materials... 
One might be disappointed by several of these specifications.

The most amazing one was the engine. OK, the seamen liked very much any kind of radial engines, but, for a fighter, it was the most irrelevant choice, because the fuselage cross section would be hampered by the cross section of such an engine
The HS 9 V had a huge diameter of 1.45 m, inducing a fuselage cross section larger than 1.7 m², which had to be added with the canopy, the two (or three) floats, the masts and the wings... 

Aerodynamically speaking, it was the worst solution.


Following the same inappropriate way, the use of fabric covering was a total nonsense, aerodynamically speaking.

So, the choice of a speed limit of only 300 kph was understandable but not wise at all. 

It is somewhat amazing to remember the program published in the same period for a torpedo float-plane - the Latécoère 298 - specified exactly the same top speed.

Indeed, a seaplane fighter could never be as nimble as her land-based counterparts. 

This implying her purpose could not be the establishment of a total air mastering over all skies but over their own fleet in deep seas.

To be useful near the enemy coasts, seaplane fighters needed to attack their target by surprise just at sunrise... So, they needed the highest possible top speed!


Moreover, the land-based fighters issued from the older contest of the French Air Force had demonstrated, at the end of 1932, top speeds ranging from 360 kph to 380 kph with engines providing less than 700 hp. 

Taking into account the maturation of significantly more powerful engines (Hispano-Suiza 12 Y and Gnome & Rhône 14 K), it was possible to obtain at least the same speed than the 2 years older land-based fighters.

Some studies were developed by other companies.
  • Dewoitine proposed a float plane straightforwardly issued from the D 500 (winner of the land based fighters contest).
  • Bernard proposed his model 110, a scaled up derivative of his Bernard 52 float plane.
  • Potez proposed the model 453, issued from the scout flying boat Potez 452, but this fighter experienced complicated take offs.
  • The biplane Romano 90, the fastest of the contest (350 kph at the begining and 368 kph later), outstandingly maneuverable, experienced (may be) some difficulties during take off, but his "Polish" upper wing dissatisfied her pilots during mock up combats.                       A far better derivative was the Romano 92 with a very well streamlined Hispano 12 Ycrs engine which allowed a top speed of 420 kph.                                                                       Nevertheless, another derivative of the float plane was built in Belgium, ordered by the Spanish Republican during the Spain War (!).


Romano 92

Just for information, the only French fighter seaplane to be sold to a foreign country were the Nieuport 123 which was rejected as land-based fighter by the French Air Forces! 

Twelve of such aircrafts were ordered by the Peruvian Air Force. They were land-based (top speed ~365 kph) but also convertible to float planes. 

The top speed of the float plane variant was 320 kph with their Lorraine Petrel engine providing 720 hp. It was said the sold fighters were using of a more powerful variant of the engine (780 hp), enabling them to reach a top speed of  335 kph.


The Loire 210


She take-off for the first time the March 201935 and the preliminary tests were successful.

The Loire was easy to fly, easy to land on the sea, as usual with a main center-lined single float (at the expense of performances (-20 kph)), a solution retained later for the float-plane variant of the Japanese Zero as also for her more recent stablemate Kyofu.


Her take-off duration was only 9 seconds with a variable pitch air-screw, 11 seconds with a fixed pitch one (the rejection threshold for the Navy was 15 seconds).

The aerobatics was easy but the commands were heavier than those of the carrier based fighters.


The catapult trials were very successful, the first ones being done without pilot but also without crash!


The top speed of the prototype - at altitude - exceeded 304 kph at 3,000 m (the top speed of the series machines is often said to have been 315 kph between 3,500 - 4,000 m. 

Exhaust pipes would have been useful (adding about 15 kph to the top speed), but never introduced!

The service ceiling exceeded 8,000 m.

The climbing times were:
·                       1,000 m in   1’ 42”
·                       3,000 m in   5’ 19”
·                       3,500 m in   6’ 26”
·                       4,000 m in   9’ 24”
·                       6,500 m in 19’ 00”

The maximum flight duration was 3 hours at 200 kph and 2 hours at 250 kph.

The armament consisted in four 7.5 mm Darne machine guns in the wings, a rather light punch.

The official trials were finished at the Fall of 1935.



Personal document of the author - Loire 210, from standard (smooth cowling), before to be put on her catapult 


The Loire-Nieuport company staff, perfectly aware of the aeronautical evolution, wanted to enhance the speed capabilities of its fighter. 

So, they replaced the initial Hispano 9 V with a Gnome & Rhône 14 K.

The new engine was more powerful and, also, had a 27 % smaller cross section, allowing a lower fuel consuming in flight.

The modified aircraft was re-designated Loire 211 and flew at a top speed of 330 kph, but unfortunately, the engine was not fitted with a reduction gear box and the air-screw, running too fast, was not optimal. 

It was anticipated that, with a reduction gearbox and a better air-screw, the Loire 211 would be able to fly at 350 kph. 


Another study was proposed, using the Gnome & Rhône 14 Mars 700 hp engine, allowing a  200 kg lighter empty-weight and a 60 % slimmer fuselage cross-section.

This proposal was really promising, even the speed was to be quite identical to that of the Loire 211 (the publicity claimed 355 kph), the combat radius would have been very larger, allowing a much more interesting tactical role, as also the capability to embark these fighter on lighter ships (which were much more numerous).

The only aerodynamic evolution was the NACA cowling which adopted a quite smooth shape (alas, with a too large air-intake...).




The French Navy ordered the less performing variant!


Very late, at the end of 1936, some one full year after the termination of the official tests (!), the French Navy informed unofficially the Loire-Nieuport company twenty Loire 210 examples were ordered. 

But the official order was emitted only the May 12, 1937.

These delays - whose narrative have said they were justified by "experiments" - were totally abnormal. 

What kind of "experiment" could have been made with only one prototype? 

It was possible, indeed, to made true experiments, i.e. dedicated to war tactics !

For example, one could have used fighter groups gathering, at least, the three prototypes (even if they were issued from different factories) during long flight around a real fleet doing realistic combat simulations of the defense of the fleet against big aircrafts as were the civilian one but experimental Laté 521, or against Laté 290 and later Laté 298 torpedo bombers.

So, the more relevant tactics could have been selected and perfected, as also, the needs for a more modern fighter, knowing the recent advances in aerodynamics.

Obviously, all these experiments would have been done from the tropical or equatorial regions to the Arctic or Antarctic ones, to know all possible shortcomings associated to the different climatic conditions. 

Unfortunately, to my knowledge, none of such experiments were done.

The very late ordering had forbidden the awareness of the true capabilities allowed (or not) by such seaplane fighters.


A fighter protecting the Fleet, far from the enemy coasts, when you have no aircraft carrier... 


The twenty ordered Loire 210 could be installed either on the catapult of a battleship or a cruiser. 

In 1939, the French Fleet gathered 18 ships able to launch the Loire 210: The Lorraine battleship, the Dunkerque and Strasbourg battle cruisers, the seven 10,000 wt heavy cruisers, the seven La Galissonnière class light cruisers (7 500 wt) and the Commandant Teste seaplane carrier. 

So, if these aircrafts have been equally distributed between the existing French naval forces (North Atlantic, South Atlantic, Indian Ocean, Indochina and French Polynesia), there could be only two or three of these floatplanes for each fleet (taking into account several machines for training or repair).

Another distribution could also have been obtained, with only three fleets equipped, e.g. one for the North Atlantic, one for the South Indian Ocean and one for the Indochina. 

In tolerable sea conditions and only during daylight, with about 5 fighters for each fleet, it would had been possible to maintain two fighters in readiness and two other as reinforcement, the last being in maintenance. 

In case of real attack, four fighters were available. 

So, the possible enemy heavy multiengined scout planes - the only aircrafts able to fly really far from the coasts - could be downed, allowing all the desired secrecy for the involved French fleets.



One technical problem remained: How to retrieve the launched fighters?


The first current solution found was to pick up the fighter with a crane. This process was perfect in peace times. 
During a battle, it was too time consuming, endangering the ship and the fighter. 

Moreover, in rough sea, the likelihood to achieve such a goal became very little.

So, the French naval engineers had elaborated an interesting method (may be inspired by a German experiment). 

A notched carpet was lowered at the stern of the ship (the notches being made of piece of timber). 




Personal document of the author - A  Gourdou-Leseurre 812 climbing on the notched carpet as would do the Loire 210


The floatplane pilot had to follow the ship with the excess of speed resultant of his landing and to climb on the middle of the notched carpet on which the float will be quickly hooked, allowing the sailors to retrieve both the aircraft and her pilot.

It was a sporting and rather daring method, but, after a thorough training, the retrieval of the aircrafts was very faster than with a crane. 

One shortcoming was the difficult maintenance of these carpets.

Nevertheless, such carpets, tested successfully on the Commandant Teste, were fitted on the recent and light cruisers of 7,500 tonnes. 

These excellent cruisers had a square stern to ease the deployment of their carpet.

In French publications, you can read such maneuvers needed to limit the speed of the ship to 15 kts. 

Some captains complained it was dangerous and time consuming...

In my personal opinion, the true danger for any French fleet was especially to be spotted by a Focke-Wulf 200!

OK, this large German aircraft was theoretically faster than the Loire 210 – she had a speed 360 kph - but, during an operation, when she flew far from her own coasts, her pilots flied at no more than 260 kph, in order to save the flying range of his machine as also the capacity to return at home.

Moreover, she was never able to turn, to dive or to climb as tightly as any fighter could do.

By definition, when the crew members were watching for Allied civilian or military vessels, the watch of the skies being not very exciting. 

So, a Loire 210, relatively small and flying easily higher - at about 3,500 m - could approach in the sun by a weak slope dive and attack the recce bomber long before the FW 200 could accelerate enough to escape. 

Yes, the four Darne machine guns were very light machine guns (0.3 cal.), but the FW 200 was very brittle, especially during escape maneuvers!



A broken Focke-Wulf 200 after her landing - a frequent picture - As you can see, there is no clear evidence of battle damage...

Yes, I know this weakness because these wrecks have been frequently published after the war. 

However, the Focke-Wulf 200 was an absolutely famous aircraft since her really brilliant crossing of the North Atlantic in August 1938. 

At this very moment, she was only a passenger liner – actually designated as Kurier - whose speed was mostly related to her aerodynamics and her lightness. 

The military variant Condor, with her gondola, her turrets and her armament, was unwisely overloaded and displayed a significant loss of her fineness.
She was 23.45 m long and weighted 17,000 kg empty and 24,500 kg for take off.
Her wingspan was 33 m and her wing area totaled 120 m².
The wing loading was 204 m².
She carried 5 m.g. and a bomb charge of 1000 kg (internally).

Her total power increased from 3,600 hp to 4,800 hp, her empty weight was circa 3,000 kg heavier and her take off weight was more than 8,000 kg (or ~50 %) heavier than the civilian FW 200! 

Any current strengthening of the structure could not fix so unexpected constraints (a complete redesign would have been the only fair solution).

So, structural weakness could be easily expected, including by the German deciders.
Nevertheless, they bet on a weak likelihood of encountering fighters...



From the other hand, Louis Bonte (in Histoire des Essais en Vol, Docavia #3) as said the problem of the Loire 210, was that if there was any encounter of land based fighters like the Messerschmitt Bf 109, the Loire 210 would be "an innocent victim".

This "honorable" person seemed to forget an important fact: The Bf 109 had a total autonomy of only 660 km

At most, that allowed her a combat radius from 150 km up to 200 km. A very short distance, as it was demonstrated later during the Battle of Britain.

The least bullet impact in the engine, the water radiator, the oil one or the fuel tank would signify a very “uncomfortable” ditching on the sea, with a quasi automatic lethal issue...

During the Campaign of France, the Dewoitine 520 was alone among the Allied single-engined fighter able to fly 1,500 km, allowing her to fly up to 400 km from the coasts (with some hazards, nevertheless...).



So, the seaplane fighters were needed for any fleet which don't have aircraft carrier to cover its ships.

Are you interested by a demonstration? 

OK, remember what happened in December 10, 1941, in Malaya.

The then-promising British Admiral Thomas Phillips was in command of a fleet dubbed Force Z, consisting in four destroyers and two battleships, the HMS Repulse and the HMS Prince of Wales

This fleet appeared not very strong, having no cruiser and no protecting submarine.

None aircraft carrier was available to strengthen this force, the only one, the HMS Hermes, was left at Capetown "for lack of speed" had said the (full) Admiral Phillips. 

The same expression was later used by Phillips to left some Allied destroyers and cruisers at Singapore

Such judgments demonstrated the poor tactical sense of Admiral Phillips.

Knowing the landing of Japanese forces in Malaya, the same December, 8, than the Pearl Harbor attack, Phillips launched an attack of the Japanese convoy and instructed the RAF fighters to help the Allied ground forces, leaving his ships without air cover. 

Doing this way, he fulfill all the Japanese wishes

The December 9, one of the escorting destroyers signaled a Japanese scout plane in sight. 

OK, Phillips had no aircraft carrier, however, if each of his two battleship had a fighter float-plane on her catapults, even an as obsolete fighter as was the Loire 210, this scout plane could be easily downed. 

But, unfortunately, Phillips had no fighter seaplane at all. 

That triggered the following events:
  • The I-58 submarine reported the position of the Force Z the December, 10. 
  • A twin-engined recce-bomber Mitsubishi G3M spotted the British fleet and  maintained contact.
  • The Japanese staff ordered the attack by several waves of bombers (flying only at 260 kph to allow them a safe return).
  • In only 3 hours, the brand new Prince of Wales battleship and the old Repulse battlecruiser disappeared from the surface of the sea. 
Only four Japanese bombers were downed.

Circa 850 sailors disappeared with their battleships.

Obviously, such a disaster had multiple causes. 


The first one was the overconfidence of Phillips who clearly despised the Japanese sailors and airmen as also their machines.

His second fault was to be too eager to go to combat, with his AA fire control disabled by the tropical moisture (he did not accept to left sufficient time for fixing the bugs), with a weak escort and no fighter cover.

His third fault had been to privilege the radio blackout over presence of an air cover.

But Phillips was certainly not responsible of the excellent tactic used by Japaneses forces, as he was not responsible of the Churchill's orders.


Many very courageous men were killed because the Royal Navy was not aware of the mutation needed to the fleets by the appearance of the war planes... even one full year after her brilliant aerial attack against the Regia Marina fleet at Tarento! (Remember, the Admiral who ordered and won the Battle of Tarento was the great Admiral Andrew Cunningham!)




The Loire 210: A delayed and very short operational career



The whole series of the Loire 210 was built between the November, 18, 1938 and the September, 8, 1939.


The French Navy had commissioned the first half of them between June and July 1939 and the second half from August to November.

The training proceeded normally but the new device triggering the fire of the guns - instead of a classical Bowden cable - was ill-conceived, adding 0.3 to 0.5 second delay before the shot! 

So the marksmanship of the pilots was annihilated, as it happened also for the contemporary Morane-Saulnier 406 pilots.


Two of the Loire 210, #3 and #4, were respectively in board of the Dunkerque and Strasbourg battle cruisers at the 1st day of the nazi offensive against Poland.

They were used to train the AA, but never to elaborate defensive strategies !!!

Lucien Morareau (the greatest expert in the French Aéronavale history) tell us the different steps of training, fairly done, as, also, the annoyance of the captains of the ships the Loire 210 had to defend!

As all the other sailors in the World, but the Japanese ones, they were completely blind to the numerous weakness of their ships facing an aerial attack.

The French captains were badly sanctioned in July 1940 when, after the operation Catapult, some Swordfish of the Royal Navy attacked again the Dunkerque and killed 200 sailors!


There was a nasty legend about the Loire 210 fighter. 

It was said that this float-plane was ill-conceived and that some crashes had caused casualties.


Yes, 2 crash occurred, but none of them induced any injury. One was a water landing at clearly excessive speed on a rather rough water, resulting of the written off of this entire float-plane.

The other occurred after a fighter pilot expressed some worries about his fighter. The Squadron Leader, L.V. Ziegler, take off with that fighter, launching a very savage session of aerobatics.

At the end of the descending trajectory of a loop, the central float drop out, followed by the folding of a wing just before the disintegration of the plane. 

Fortunately, the parachute opened automatically, saving L.V. Ziegler.

The actual explanations concluded to a left wing failure.


However, as Lucien Morareau tells recently on these accident, it seems likely that the mechanical links between the float and the fuselage and the wing were not sufficiently robust. 

It is also possible that the fabric covering of the wing induced a lack of rigidity of the whole assembly.

From the other hand, in several anecdotes, some pilots signaled a high level of vibrations.

If you consider the amazing number (22!) of the sustaining masts, such vibrations might have been created by them, endangering the structure of the aircraft.

Some judicious fairing might have avoided such vibrations and, also, improved substantially the top speed of the Loire 210...


Admiral Lartigue, who had triggered the program of the seaplane fighters, finally, stopped the experience at the end of November 1939, transferring the trained pilots to land based (and future carrier based) fighters or dive-bombers units.

At this very time, the French Navy used the Béarn as an aircrafts lorry, privileged the Richelieu and Jean-Bart Battleship against the Joffre and Painlevé aircraft carriers and ordered the fighter float plane Dewoitine HD 780!

All these decisions were absolutely inconsistent!

The time used to achieve quickly the 2 battleships could have been used to finish 3 aircrafts carriers, the armor plates of these huge battleships could have permitted the finishing of the bunkers in the Sedan vicinity, and so on.

So, in March 1940, when the Allies launched the Campaign of Norway, they did not have any air cover for their ships!
