Power is the rate of performing work or transferring energy. Power measures how quickly the work is done. Power is always expressed in units of energy divided by units of time. A traditional unit of power is the horsepower, which is equal to the amount of power required to lift 550 pounds at a rates of 1 foot per second. The SI unit of power is the watt, which is equals the power needed to do 1 joule of work per second. There are about 746 watts in 1 horsepower.

In WWII the Japanese Zero plane was the most advanced fighter plane which generated about 746,000 watts of power. WWII was a long time ago and a lot of things have changed, we know have more advanced technology. The F-117a stealth fighter is one of the most advanced planes today, they have the new F100-PW-200 engine which produces about 74,900,000 watts of power.
