In May 1961, the US announced the goal of landing a person on the Moon by 1970. During the same month, the "On Reconsideration of the Plans for Space Vehicles in the Direction of Defense Purposes" report set the first test launch of the N1 rocket for 1965. In June, Korolev was given a small amount of funding to start N1 development between 1961 and 1963. At the same time, Korolev proposed a lunar mission based on the new Soyuz spacecraft using an Earth orbit rendezvous profile. Several Soyuz rocket launches would be used to build up a complete Moon mission package, including one for the Soyuz spacecraft, another for the lunar lander, and a few with cislunar engines and fuel. This approach, driven by the limited capacity of the Soyuz rocket, meant that a rapid launch rate would be required to assemble the complex before any of the components ran out of consumables on-orbit. Korolev subsequently proposed that the N1 be enlarged to allow a single launch lunar landing. In November-December 1961, Korolev and others tried to further argue that a super heavy lift rocket could deliver ultra heavy nuclear weapons, such as the just tested Tsar Bomba, or many warheads (up to 17) as further justification for the N1 design. Korolev was not inclined to use the rocket for military uses, but wanted to fulfill his space ambitions and saw military support as vital. The military response was lukewarm - they thought the N1 had little military usefulness and was worried it would divert funds away from pure military uses. Korolev's correspondence with military leaders continued until February 1962 with little progress.
