Cross-Section of the steamship La Champagne showing the boiler room, a funnel, coal bunkers, and passengers going about on the decks.
La Champagne was equipped with cylindrical iron boilers feeding a power plant which could deliver between 7,000 and 7,500 horsepower in regular service. Like her sister ships La Bourgogne, La Bretagne, and La Gascogne, she was built with the help of government subsidies, on the condition she could be taken over in case of war.
