Most Powerful Rockets by Payload Capacity to Low Earth Orbit

About This Dataset

This chart compares the most powerful orbital rockets ever flown by their maximum payload capacity to low Earth orbit, in metric tonnes. The Saturn V, which carried Apollo astronauts to the Moon, still leads at 140 tonnes, ahead of NASA's modern SLS Block 1 at 95 tonnes.

Analysis

The most remarkable fact in this ranking is its age: the Saturn V, designed in the early 1960s with slide rules, remains the most powerful rocket ever successfully flown at 140 tonnes to orbit. The Soviet Energia, its closest rival at 100 tonnes, flew only twice before the USSR collapsed. Among rockets flying today, the gap between heavy-lift and everything else is stark - SpaceX's Falcon Heavy (63.8 tonnes) lifts nearly three times more than the workhorse Falcon 9 (22.8 tonnes), yet still falls well short of the 1960s benchmark. NASA's SLS at 95 tonnes finally approaches Saturn V territory for the Artemis Moon program. The clustering of Proton, Falcon 9, and Long March 5B in the 22-25 tonne band shows how similar the world's standard heavy launchers have become.
