Patreon 71: Why did the French Navy not more fully embrace carrier aviation after WWI?

Bearn provides the immediate answer to why French carrier aviation struggled after World War I.

No. The Normandie design was slow and unexceptional, while a purpose-built carrier would have served France better than the conversion.

France needed sea lines for merchant trade and global access as well as its colonial links after a devastating war.

French naval personnel appear to have served at Verdun, and the navy performed other necessary wartime duties, but it lacked a celebrated fleet victory that could anchor its postwar political case.

A comparison with the Royal Navy shows why the French Navy had less political capital after World War I.

France lost future families, skilled mentors, and accumulated knowledge as well as the people counted among World War I casualties.

Frequent prime ministers and marine ministers made long naval programs harder to sustain through treaty talks and ship construction.

France combined a large agricultural sector with substantial but geographically disconnected industry.

The stream explains why a small French carrier community could not develop leaders and doctrine like larger naval air arms.

Probably not seriously. Her broad beam, low speed, and heavy battleship hull helped offset the tall conversion, although they did nothing for carrier performance.

They needed the confidence of parliament, and coalition or minority governments could lose it rapidly.

Bearn's mixed machinery pursued cruising economy without producing the coherent high-speed plant a fleet carrier required.

French naval chiefs had reasonable continuity, but less rank and authority than their Royal Navy counterparts when pressing long-term policy.

No, not primarily. Bearn needed repairs and was not considered ready for an Atlantic crossing.

France already had a battleship hull available and followed the conversion path used by other carrier navies, even though that choice consumed scarce treaty tonnage.

Probably Britain, because British yards could build more carrier hulls than the Royal Navy could crew while the United States could use the carriers it built.

A captured Bearn could have hurt a German surface group by forcing every accompanying ship down to her 21.5-knot pace.

A direct endurance comparison shows that Bearn surrendered speed without gaining a meaningful cruising-range advantage.

Bearn outlasted some true fleet carriers by shifting into anti-submarine and accommodation roles.

The Maginot Line absorbed money and political attention, leaving carrier aviation outside France's central defense argument.

An improvised Canadian boarding action comes with a warning that the story's exact details were still being resolved.

Yes. Even lighter fortified belts toward the Channel and Normandy could have provided successive positions and somewhere for retreating forces to regroup.

Washington and London treaty limits left France with room for carriers, but its fast battleship choices did not produce matching air power.

France still relied on a 21.5-knot carrier after Britain and the United States had moved comparable pioneers into secondary roles.

Treaty limits and industrial capacity did not make follow-on carriers impossible; French choices left suitable large-ship yards unused.

Yes, within the separate treaty allowances. France could not simply add five or six more battleships, but it could have paired two fast battleships with two carriers based on related hull and machinery ideas.

Yes. France's cruiser program showed that four or five yards retained useful warship-building capability.

Coalition assumptions encouraged France to supply fast capital ships while relying on Britain for carrier aviation.

Three slow lifts, clamshell doors, overhead rails, and a small air group limited Bearn's flight-deck tempo and training value.

Their cycles were generally measured in seconds, with British examples around 50 to 90 seconds depending on aircraft weight and the source.

American designers introduced deck-edge elevators, while British centerline practice reflected their deck construction and experience operating in the North Sea and North Atlantic.

No. The main delay came from the carrier's lift system, so experience could not remove the mechanical bottleneck.

No. Bearn had a complement of about 875 people, so a substantial number of French sailors served in her compromised carrier system.

Joffre corrected several of Bearn's handling failures, but combined an unusual layout with a small continuous-operations air group.

Very few in a sustained program, because Bearn operated only about 27 aircraft and did not create the demand or experience needed for continuous development.

French planners could expect British or American carrier support in the oceans where France was least able to operate alone.

For a smaller navy, avoiding carriers also avoided the cruiser and destroyer commitment needed to protect them.

The absence of an Italian carrier reduced competitive pressure on France inside the Mediterranean.

France had less interservice conflict over carriers because its navy possessed only Bearn and carried little weight in national politics.

The concluding argument finds a navy building fast, well-armed ships without the carrier needed to make that force coherent.

The unbuilt Normandie layout shows the limits of France's prewar battleship approach and why a later design break could be productive.

Hood was not the most relevant benchmark because France was planning primarily against Italy, although the Italian Francesco Caracciolo class would also have posed a serious challenge.

Francesco Caracciolo, because its 28-knot speed and eight 15-inch guns let it choose when to fight despite Lyon's heavier sixteen-gun broadside.

The closing discussion distinguishes respect for French sailors and ships from British distrust of unstable political communication in 1940.
