Imagine that luck, spent at least 8 billion and 20 years to build ships which they bragged would be heavily used in next 50 years, but got rendered obsolete in just 5 not to mention they break all the time. Certified French predreadnought moment.

And speaking of dreadnoughts, it wouldn’t be even first time. UK did build a last and theoretically most modern battleship in the world, but not only it was armed in the retired 1916 main guns and turrets, but it was comissioned in 1946, nearly 5 years after battleships were proven to be obsolete.
