French naval innovations have played a significant role in maritime history, particularly during the Age of Sail. The development of the French ship of the line allowed for more powerful and heavily armed vessels, which were crucial in naval battles. Innovations in ship design, such as the use of copper sheathing, helped protect hulls from marine growth and increased speed. In the 19th century, France advanced further with the introduction of steam-powered ships, enhancing naval mobility. The French Navy also pioneered the use of ironclad warships, which provided better protection and firepower. These innovations laid the groundwork for modern naval warfare.
