9. Engine Power
A system of four steam turbine engines, with a staggering 150,000 horsepower,
propelled the massive ship. Twelve boilers, heating steam to 700°F, fed
the four engines, which then moved an array of propellers. Each propeller blade
was nearly three times as long as a man of average height. At Yamato's
maximum speed of 32 mph, the propulsion system consumed 70 tons of fuel oil
every hour.
