Russian heavy-lift orbital launch vehicle. It was originally planned the N1 would form the basis of a family of launch vehicles that could replace existing ICBM-derived boosters. The N11 would use the second, third, and fourth stages of the N1. This would give it a lift-off mass of 700 metric tons and a 20 metric ton payload into low earth orbit. It could replace Chelomei's Proton launch vehicle in the medium-lift role.

1967 May 5 - . LV Family: N1, Proton, N11.
  • The Soviet of Chief Designers met with the Civil Chief Designer UR500K-L1 and recommended that podsadka be dropped and direct flight become the baseline. - . Related Persons: Mishin. Spacecraft: Block D, Soyuz, Soyuz 7K-L1, Soyuz 7K-OK.

    This was evidently to make possible the objective of a Soviet man around the moon before 4 October 1967. The reasons given were:
    a) The successful flights of the UR-500K and Block D on the L1 2P and 3P and the further 4 separate UR-500 launches provided confidence in the launch vehicle's reliability.
    b) The main delays with L1 development will be in relation to development by BTsVM of the Argon-11 digital computer for its control system.
    c) The failure of 7K-OK number 4 (Soyuz 1) indicated a delay in development of docking in earth orbit.
    It was recommended that the 7K-L1 launch sequence be revised to two missions per month as follows:
    - 4L - "Zond" unmanned 17 - 29 June 1966
    - 5L - unmanned, circumlunar, 27 June - 5 July
    - 6L - "Zond", unmanned, 12 - 17 July
    - 7L - unmanned, circumlunar, 25 July - 3 August
    Followed by manned launches according to astronomical constraints (which would mean 23 August, 21 September, 19 October). (Mishin Diaries 2-22)


1973 December 11 - . LV Family: N1, Proton, N11.
  • Mishin lays out his planned program in desperate notes. - . Related Persons: Mishin, Afanasyev, Sergei, Bezverby, . Spacecraft: , MKBS.

    Review materials sent from Moscow.
    1. Long-term program TSKBEM (projected) (See. Ref. 4/4748 dated 10 October 1973 from MOM).
    MKBS-1 on UR-500K (this would later be Mir)-
    Number 1 - 1977
    Number 2 - 1978 - 79
    MKBS on N-1 - Number 1 - 1983
    Number 2 - 1988
    N-11 (this refers to the use of the N-11 to replace the UR-500K for boosting modules to MKBS-1/Mir)
    1 - 1978
    2 - 1979
    MKTS on the basis of the first-stage N1 - 1985 with the augmented engine - 1988-90 (this is a reference to the aerospike / air-augmented N1 with the spaceplane second stage, as revealed to USAF agent Peter X in that year!)
    Performance in accordance with the "additional materials to the plan for experimental work in 1976-1990. See ref. 10414 dated 6.XII.1973.
    2. TSKBEM work plan for 1974.
    - Clarify:
    a) The number for transport spacecraft to object "A", S.A. (Afanasiev?)
    b) The number of DM (ZEM cannot produce the quantity.)
    - No specification from TSNIIMMASH for the heavy launch vehicle (not to mention its scientific and technical justification).
    3. Thematic plan for experimental work for TsKBEM in 1974.
    4. NIR
    All these materials require serious revision. (Focused, real and concrete, etc.) -Need to reduce the subject areas, the scope of work and remove excessive detail.
    Call Bezverby VK - For papers on MOK.
    Received in response via telegram a runaround (old papers are in the materials of the Academic Council). And I need - new papers. (I do not have - or have not yet found - my copies of these papers)


1974 January 2 - . LV Family: N1, R-7, N11, Molniya 8K78L.
  • On the first two days of 1974, Mishin catalogues the issues and notes his supporters. - . Related Persons: Mishin, Ustinov, Afanasyev, Sergei, Almaz, Bezverby, . Spacecraft: Soyuz, MKBS, Mir, Soyuz 7K-S, LK.

    To do:
    1. Now, when considering our long-term program and the use of near-earth space (including the Moon) for different purposes, it is necessary to clearly define the sequence of its implementation.
    Especially decide - where to start? (Especially in the present situation).
    - It is necessary as soon as possible to show the rationality inherent in the program guidelines.
    Namely a space-based MOK.
    - Optimal location for OAA systems: based on MKBS (DOS) - or visited the MPM for routine maintenance or brought near-MKBS for the same purpose.
    - Reusable transport ship based on the 7M, and then a reusable transport system based on the work on the N-1 (but with a new engine system in stage 1).
    02.I.1973
    - Space problems solved by the OAA.
    - A great resource. (even after these events)
    Where to start?
    ? (7KS)
    1. DOS 5 (6?) + 7KT + 7KTT + 7KS-OR
    7KS-OR (evidently a reconnaissance version of the 7KS) - view as the embodiment of the most efficient use of the developed equipment (Zenit-Yantar)
    Negotiations with DI Kozlov (What does he want?)
    2. All that in the first only on the basis of the 7M, to create the MTK and MPM (talks with EV Shabarov)
    What will branch NII-4 handle?
    1. Operative follow-up exploration.
    2. Armed struggle in outer space.
    (03.I.1974)
    3. The defeat of the moving targets.
    4. Electronic countermeasures
    5. Use of stationary orbit.
    6. Use of of sun-synchronous orbits.
    Means:
    Filial of NII-4 GUKOS support (but only at the lower levels): 1. R-7M; 2. N-1?; 3. N-11
    Support in the MO MO for the N-1 - signed by Alekseev and Tolubko.
    Navy is indifferent to MOK (they do not understand the prospects)
    It is necessary to establish a relationship with the customer. He is interested in this (Attract DI Kozlov!)
    (4.I.1974)
    - Write a detailed letter on MOK to Afanasyev (copied to the Central Committee) (With a draft work order)
    - Draft a memo to the Central Committee for DF Ustinov. (Long-term planning)
    - Achieve color television for the Soyuz-M (NN Detinov - CC)
    - TsKBEM review of the level of work on special equipment in related organizations.
    - Write a memo about the possibilities of "A" in the operational intelligence. (VK Bezverby together with TsNIIMASH).
    - Deal with the radio channel on the "Yantar". Orders: VK Bezverby
    - The draft memo on the need of long-term integrated planning by the state. TSKBEM work on MOK - 1st to attempt its development. (Mishin Diaries 3-167)


1974 February 28 - . LV Family: N1, R-7, N11, Molniya 8K78L.
  • Mishin conducts more brainstorming on all issues. - . Related Persons: Mishin, Afanasyev, Sergei, . Spacecraft: , MKBS, Almaz, Mir.

    21. Form a unit in TsKBEM for special equipment (e.g. classified military) (for some complexes).
    22. Develop ideas on the feasibility of developing and creating two-stage rocket for launch into low earth orbit. (Comparison with 3-stage rocket, the advantages and disadvantages).
    23. Conduct a study on the feasibility of establishing MKTS based on two-stage rocket.
    24. Conduct research on performance 2-stage rocket for launch of payloads to earth orbit using different fuel components (Including solid propellant).
    25. Elaborate design for a surveillance module based on MKBS-1 derived from the N-110.
    26. Review a 2-stage N-1 for MKBS-II, a 3-stage for moving heavy SM modules to geostationary orbit and lunar orbits.
    Questions for SA Afanasyev
    1. His attitude to R-7M. Who is going to build it?
    2. His attitude towards the N-11. 2-stage for moving spacecraft to sun-synchronous orbit).
    3. On the sequence of launches of DOS and "Almaz".
    4. On the development work on MOK.
    About MOK - based on our promising developments. Basis MOK - space-based, and it should be checked already on the DOS-5 having two connecting nodes.
    5. On the shuttle on the basis of R-7M. (Mishin Diaries 3-176)


1974 April 1 - . LV Family: N1, R-7, N11, Molniya 8K78L.
  • Mishin records his final list of planned spacecraft. - . Related Persons: Mishin. Spacecraft: , MKBS.

    1) MTKK Space Shuttle - manned version for delivery and return of the crew of astronauts on the MKBS.
    2) MTKK Space Shuttle - cargo version.
    3) SM Special Module - a non-returnable, autonomous and dockable with the MKBS (all-weather reconnaissance)
    4) MSK - the inter-satellite ship - automatic and manned. Launch vehicle - N-11 Payload = 18 tons (23 tons)
