Which rocket was known for being a liquid fuel rocket?

The Saturn V is recognized as a liquid fuel rocket due to its use of liquid propellants, specifically RP-1 (a refined form of kerosene) combined with liquid oxygen (LOX) for its first stage. It was developed by NASA during the 1960s and is famous for being the launch vehicle for the Apollo missions, including the historic Apollo 11 mission that landed the first humans on the Moon. Each of its three stages utilized liquid fuel, which allows for controlled thrust and the ability to shut down engines mid-flight—a crucial capability for complex missions such as those to lunar orbit.

While the Atlas, Falcon 9, and Space Shuttle also utilized liquid fuel in their propulsion systems, the Saturn V stands out as a legendary example of a purely liquid-fueled rocket designed for heavy lift and complex missions in space exploration history.
