Korolev proposed a larger N1 combined with the new L3 lunar package based on the [[Soyuz 7K-L3]]. The L3 combined rocket stages, the modified [[Soyuz spacecraft|Soyuz]], and the new [[LK (spacecraft)|LK lunar lander]] were to be launched by a single N1 to conduct a lunar landing. Chelomei responded with a clustered UR-500-derived vehicle, topped with the [[LK-1]] spacecraft already under development, and a lander developed by his design bureau. Korolev's proposal was selected as the winner in August 1964, but Chelomei was told to continue with his circumlunar UR-500/LK-1 work.

When Khrushchev was overthrown later in 1964, infighting between the two teams started anew. In October 1965, the Soviet government ordered a compromise; the circumlunar mission would be launched on Chelomei's UR-500 using Korolev's Soyuz spacecraft [[Soyuz 7K-L1]], aka [[Zond program|Zond]] (literally "probe"), aiming for a launch in 1967, the 50th anniversary of the [[Bolshevik Revolution]]. Korolev, meanwhile, would continue with his original N1-L3 proposal. Korolev had clearly won the argument, but work on the LK-1 continued anyway, as well as the Zond.

Korolev lobbied in 1964 for a crewed circumlunar mission, which was at first rejected, but was passed with the 3 August 1964 [[Central Committee]] resolution titled "On work involving the study of the Moon and outer space", with the objective of landing a cosmonaut on the Moon in 1967 or '68.<ref name="lindroos2007" />

In January 1966, Korolev died due to complications of surgery to remove intestinal polyps that also discovered a large tumor.<ref name="esa-20070309">{{Cite web |date=9 March 2007 |title=Sergei Korolev: Father of the Soviet Union's success in space |url=https://www.esa.int/About_Us/ESA_history/50_years_of_humans_in_space/Sergei_Korolev_Father_of_the_Soviet_Union_s_success_in_space |url-status=live |archive-url=https://web.archive.org/web/20230601184411/https://www.esa.int/About_Us/ESA_history/50_years_of_humans_in_space/Sergei_Korolev_Father_of_the_Soviet_Union_s_success_in_space |archive-date=1 June 2023 |access-date=30 April 2023 |publisher=[[European Space Agency]] }}</ref> His work on N1-L3 was taken over by his deputy, [[Vasily Mishin]], who did not have Korolev's political astuteness or influence, and was reputed to be a heavy drinker. After a few years of setbacks and four failed launches, in May 1974 Mishin was fired and replaced by Glushko, who immediately ordered the cancellation of the N1 programme and the crewed lunar mission in general, despite Mishin's assertion that the rocket will be fully operational in under two years.<ref name="acta-astro-n1">{{Cite journal |last=Lardier |first=Christian |date=1 January 2018 |title=The soviet manned lunar program N1-L3 |url=https://www.sciencedirect.com/science/article/pii/S0094576517307695 |journal=[[Acta Astronautica]] |volume=142 |pages=184–192 |bibcode=2018AcAau.142..184L |doi=10.1016/j.actaastro.2017.10.007 |issn=0094-5765 |url-access=subscription }}</ref>
