The F-1 was a workhorse engine for the US space agency NASA as the most powerful single-chamber liquid-fuelled engine ever developed.

Because the engines' serial numbers are partially missing, it remains unclear which Apollo mission they are from - that may become clearer during restoration.

The F-1 engines were designed by Boeing subsidiary Rocketdyne to power the 138-foot-tall, Boeing-built first stage of the Saturn V rockets used for the Apollo and Skylab missions from 1967 to 1973. The Saturn V's S-IC engines originally had four F-1 engines that could be hydraulically gimballed to control the rocket, but a fifth, fixed F-1 was added on later Apollo missions to add more thrust to compensate for heavier payloads.

From the Apollo 9 mission on, they burned for roughly 165 seconds after launch to take the Saturn V to a height of about 40 miles above sea level, producing 1,525,000 pound-force (lbf) of thrust apiece, or about 7,500,000 lbf altogether when all five were firing.
