Associated Launch Vehicles
YaKhR-2 Russian nuclear-powered orbital launch vehicle. First large space launcher considered in the Soviet Union. It would have had the same layout as the R-7, but with six strap-ons increased in size by 50%. The core, igniting at altitude, used a nuclear thermal engine using ammonia as propellant. Dropped in favor of development of conventional chemical propulsion. More...
OKB-456 Russian intercontinental range ballistic missile. Variant using a Glushko nuclear engine heating ammonia as a propellant. More...
Superraket Russian nuclear orbital launch vehicle. The ancestor of the N1 lunar launch vehicle, this was the first heavy lift launch vehicle actively considered in the USSR. The 2,000 tonne liftoff mass was similar to the later N1 design, but the first stage would use a staggering cluster of around 66 Kuznetsov NK-9 engines (as opposed to the modest 24 NK-15's of the first N1 configuration). The real difference was in the second stage, which used the nuclear YaRD engine, giving the launch vehicle nearly double the later N1's payload capacity. More...

Nuclear/Ammonia Nuclear thermal engines use the heat of a nuclear reactor to heat a propellant. Although early Russian designs used ammonia or an ammonia/alcohol mixture as propellant, the ideal working fluid for space applications is the liquid form of the lightest element, hydrogen. Although successfully ground-tested in both Russia, they have never been flown due primarily to environmental and safety concerns. More...
