If one would say that Russia's slow action in the construction of dreadnoughts was due to the two major flaws of insufficient research and development capabilities and lack of funds, then France, as one of the old powers, cannot justify their slow action in the field of dreadnoughts.
In fact, the French were not slow in the field of dreadnoughts, it was just because the navy's budget had already been spent on the construction of the pre-dreadnought Danton-class battleships. Not only did the navy lack the budget, but the French shipyards also did not have enough construction capabilities to start new dreadnoughts.
Because of this, despite the Danton-class battleship falling behind the times after the birth of the Dreadnought-class battleship, the French still stubbornly waited until 1911 for all the Danton-class battleships to be completed before they began the construction plan for the dreadnoughts.
