N1F
Part of N1 Family
N1F - 1974
N1F - 1974
N1F - 1974 Configuration (N1 s/n 8L)
Russian heavy-lift orbital launch vehicle. The N1F would have been the definitive flight version of the N1, incorporating all changes resulting from the four flight tests of the vehicle, including the new Kuznetsov engines and 10% greater liftoff mass by using superchilled propellants in all stages. N1 8L would have been the first N1F configuration flight, with launch planned in the third quarter of 1975 at the time the project was cancelled.

1970 June - . LV Family: N1. Launch Vehicle: N1F.
  • Development of engines for N1F authorised - . Nation: Russia. Spacecraft Bus: L3M. Spacecraft: L3M-1970.

    Full go-ahead to develop a liquid hydrogen/liquid oxygen high energy upper stage for the N1F. The multi-engine Block Sr would have a propellant mass of 66.4 tonnes. In July Kuznetsov was given authorisation to design substantially improved versions of the N1 lower stage rocket engines. The N1 that would utilise these engines was designated the N1F and would have a payload to a 225 km orbit of 105,000 kg.
