Kerosene Rocket Fuel
Highly refined propellant began as “coal oil” for lamps.
A 19th-century petroleum product made America’s 1969 moon landing possible. On July 16, 1969, kerosene rocket fuel powered the first stage of the Saturn V of the Apollo 11 mission.
Four days after the Saturn V launched Apollo 11, astronaut Neil Armstrong announced, “Houston, Tranquility Base here. The Eagle has landed.” His achievement rested on new technologies – and tons of fuel first refined for lamps by a Canadian in 1848.
Powered by five first-stage engines fueled by “rocket grade” kerosene, the Saturn V was the tallest, heaviest and most powerful rocket ever built until the SpaceX Starship. Photos courtesy NASA.
During launch, five Rocketdyne F-1 engines of the massive Saturn V’s first stage burn “Rocket Grade Kerosene Propellant” at 2,230 gallons per second – generating almost eight million pounds of thrust.

Saturn’s rocket fuel is highly refined kerosene RP-1 (Rocket Propellant-1 or Refined Petroleum-1) which, while conforming to stringent performance specifications, is essentially the same “coal oil” invented in the mid-19th century.
Canadian physician and geologist Abraham Gesner began refining an illuminating fuel from coal in 1846. “I have invented and discovered a new and useful manufacture or composition of matter, being a new liquid hydrocarbon, which I denominate Kerosene,” he noted in his patent.

By 1850, Gesner had formed a company that installed lighting in the streets in Halifax, Nova Scotia. In 1854, he established the North American Kerosene Gas Light Company at Long Island, New York.
Although he had coined the term kerosene from the Greek word keros (wax), because his fluid was extracted from coal, most consumers called it “coal oil” as often as they called it kerosene.
By the time of the first U.S. oil well drilled by Edwin Drake in 1859, a Yale scientist (hired by the well’s investors) reported oil to be an ideal source for making kerosene, far better than refined coal. Demand for kerosene refined from petroleum launched the nation’s exploration and production industry.
Electricity replaced kerosene lamps and gasoline dominated 20th century demand for transportation fuel, but kerosene remained as a powerful fuel choice.
Jet Cars
Nathan Ostrich built the first jet car in 1962 using an engine originally designed for the North American F-86 Sabre jet fighter. Powered by a General Electric J47 at Utah’s Bonneville Salt Flats, his Flying Caduceus set a world record of more than 330 mph.
On November 7, 1965, California race car driver Art Arfons increased the land-speed record to 576.553 miles per hour on the famous one-mile strip. The Ohio drag racer’s home-made Green Monster was powered by JP-4 fuel (a 50-50 kerosene-gasoline blend), in an afterburner-equipped F-104 Starfighter turbojet jet engine.
A kerosene-gasoline blend powered the F-104 jet engine of the Green Monster to world records,.
Arfon set the world land-speed record three times between 1964 and 1965, in what became known as “The Bonneville Jet Wars.”
Record challenger Craig Breedlove’s Spirit of America Sonic 1 in 1965 used a jet engine from an F-4 Phantom II to defeat the Green Monster and set a record of 600.601 mph, which lasted until 1970, when the Blue Flame Natural Gas Rocket Car reached 630.388 mph.
Kerosene Rockets
Kerosene’s ease of storage and stable properties attracted early rocket scientists like America’s Robert H. Goddard and Germany’s Wernher von Braun. During World War II, kerosene-fueled Nazi Germany’s notorious V-2 ballistic missiles.
Decades of post-war rocket engine research and testing led to the Saturn V’s five Rocketdyne F-1 engines. The F-1 was the most powerful single-combustion chamber engines ever developed, according to David Woods, author of How Apollo Flew to the Moon, 2008.
The Rocketdyne F-1 engines, 19 feet tall with nozzles about 12 feet wide, include fuel pumps delivering 15,471 gallons of RP-1 per minute to their thrust chambers. The Saturn V’s upper stages burn highly volatile liquid hydrogen (and liquid oxygen in all three stages).
The five-engine main booster held 203,400 gallons of RP-1. After firing, the engines can empty the massive fuel tank in 165 seconds.

The Apollo 11 landing crowned liquid-rocket fuel research in America dating back to Goddard and his 1914 “Rocket Apparatus” powered by gasoline. In March 1926, Goddard launched the world’s first liquid-fuel rocket from his aunt’s farm in Auburn, Massachusetts.
Although gasoline will be replaced with other propellants, including the liquid hydrogen and liquid oxygen used in the space shuttle’s external tank, RP-1 kerosene continues to fuel spaceflight.
Cheaper, easily stored at room temperature, and far less of an explosive hazard, the 19th-century petroleum product today fuels first-stage boosters for the Atlas, Delta II, Antares, and the latest SpaceX rockets. Reusable SpaceX Falcon 9 rockets have nine Merlin engines burning kerosene fuel and generating 1.7 million pounds of thrust.
Last launched in 1972, the Saturn V was the most powerful rocket ever built, until it was surpassed by SpaceX’s Starship — fueled by liquid oxygen and liquid methane.
