The N1 stood 105 meters (344 ft) tall and weighed 2788 metric tons (6.1 million lb) fully fueled. This compares with 110.7 meters (363 it) and 2913 metric tons (6.4 million lb) for the American Saturn V. The first three stages of the N1, blocks A. B, and V. each took the form of a truncated cone containing a spherical kerosene tank above a larger liquid oxygen (LOX) tank. The first stage, Block A, was powered by 30 NK-33 engines, together producing 4620 metric tons (10 million lb) of thrust. This far exceeded the 3469 metric ton (7.65 million lb) thrust of the American Saturn V Moon rocket. The N1's "KORD" (Russian acronym for control of the work of the engines) system steered the rocket in pitch and yaw by throttling the 24 fixed outer engines. Roll control was maintained by routing engine turbine exhaust through six swivelled nozzles. Arrayed around the base of the N1's first stage were four grating stabilizers, each consisting of a cross hatched array of metal strips (acting as fins) held in a horizontal frame After a first stage burn of 110 seconds. the second stage was to ignite its eight NK-43 engines for a 130-second burn. Finally, the third stage would insert the L-3 complex into orbit with a 400-second burn of its Four NK-31 engines.
