How much better would France's seventeen pre-dreadnoughts be without the Jeune École's influence?
Short answerThere is no firm answer without specifying the replacement doctrine. A rival battleship faction could also produce an imbalanced fleet.
NotesThe quality of France's seventeen pre-dreadnoughts without the Jeune École depends on the doctrine that replaces it. A rival faction favored concentrating on the largest and most powerful battleships. Its dominance could produce more effective ships, but could also produce slow, overweight vessels burdened by thick yet ineffective armor. Procurement becomes vulnerable when a faction gains enough power to force every decision through its own assumptions. A balanced fleet requires an alternative policy that avoids that concentration of power.
