The N1 (from Ракета-носитель Raketa-nositel', "Carrier Rocket"; Cyrillic: Н1)[5] was a super heavy-lift launch vehicle intended to deliver payloads beyond low Earth orbit. The N1 was the Soviet counterpart to the US Saturn V and was intended to enable crewed travel to the Moon and beyond,[6] with studies beginning as early as 1959.[7] Its first stage, Block A, was the most powerful rocket stage ever flown for over 50 years, with the record standing until Starship's first integrated flight test.[8] However, each of the four attempts to launch an N1 failed in flight, with the second attempt resulting in the vehicle crashing back onto its launch pad shortly after liftoff. Adverse characteristics of the large cluster of thirty engines and its complex fuel and oxidizer feeder systems were not revealed earlier in development because static test firings had not been conducted.[9]
The N1-L3 version was designed to compete with the United States Apollo program to land a person on the Moon, using a similar lunar orbit rendezvous method. The basic N1 launch vehicle had three stages, which were to carry the L3 lunar payload into low Earth orbit with two cosmonauts. The L3 contained one stage for trans-lunar injection; another stage used for mid-course corrections, lunar orbit insertion, and the first part of the descent to the lunar surface; a single-pilot LK Lander spacecraft; and a two-pilot Soyuz 7K-LOK lunar orbital spacecraft for return to Earth.
The N1 started development in October 1965, almost four years after the Saturn V, during which it was underfunded and rushed. The project was badly derailed by the death of its chief designer Sergei Korolev in 1966; the program was suspended in 1974 and officially canceled in 1976. All details of the Soviet crewed lunar programs were kept secret until the USSR was nearing collapse in 1989.[10]

Because the first stage was so big, the decision was made to forego building a separate test facility for it, and instead to try to discover any problems with a series of full-up launches. In hindsight, this would prove to be a mistake, because each of the four launch attempts of the N-1 resulted in failure due to various problems with the first stage.
