The F-1 is a rocket engine developed by Rocketdyne and used in the Saturn V. Five F-1 engines were used in the S-IC first stage of each Saturn V, which served as the main launch vehicle in the Apollo program. The F-1 is still the most powerful single-chamber liquid-fueled rocket engine developed (the RD-170 is more powerful but it has 4 chambers).

The F-1 is still the most powerful single-chamber liquid-fueled rocket engine developed (the RD-170 is more powerful but it has 4 chambers).
The F-1 was originally developed by Rocketdyne to meet a 1955 US Air Force requirement for a very large rocket engine. The eventual result of that requirement was two different engines, the E-1 and the much larger F-1. The E-1, although successfully tested in static firing, was quickly seen as a technological dead-end and was abandoned for the larger, more powerful F-1. The USAF eventually halted development of the F-1 because of a perceived lack of requirement for such a large engine. However, the recently created NASA appreciated the usefulness of an engine with so much power and contracted Rocketdyne to complete its development. Test...
