Just to give you an idea of the relative size of the N-1 Saturn V and the Soviet N-1 Moon Rocket: On July 3, 1969, the biggest explosion in the history of rocketry occurred when the Soviet N-1 rocket exploded and subsequently destroyed its launchpad. After four unsuccessful launch tries of the Soviet counterpart to the NASA Saturn V rocket the Russian Moon program was cancelled in May 1974.
The S-II stage of the Saturn V rocket is hoisted onto the A-2 test stand in 1967 at the Mississippi Test Facility, now the Stennis Space Center. This was the second stage of the 364-foot tall Moon rocket. The second stage was powered by five J-2 engines. (Great Images in NASA)
