F-1 Rocket Engine

The F-1 Rocket Engine is the most powerful single-nozzle liquid fueled engine ever used.

The F-1 Rocket Engine was developed to meet a  1955 United States Air Force requirement.  The first static firing of the full stage developmental F-1 was in March 1959.

The rocket engine is 19 feet long and 12.4 feet in diameter. It weighed 18,416 lbs dry and 20,096 lbs burn out. The F-1 rocket engine produced 1.5 million lbs of thrust.

The F-1 was used in the Saturn V. Five of these were used as the first stage of the rocket: one in the middle and the other four around the middle rocket engine. To enable the Saturn V to move in a specific direction, the four outer F-1 Rocket Engines swiveled (gimbled) to move the rocket in the direction needed.
