RT-23 15Zh44 Ukrainian intercontinental ballistic missile. The draft project for the silo-based RT-23 with the 15F143 warhead was completed in December 1979. Trials of this basic version began at Plesetsk on 26 October 1982. The basic RT-23 was accepted for military service on 10 February 1983, but the decision was taken not to put it into production. All resources were to be devoted to an improved RT-23UTTKh. More...
RT-23U 15Zh60 Ukrainian intercontinental ballistic missile. Design began of the silo-based version of the RT-23UTTKh on 9 August 1983. More...
RT-23 15Zh52 Ukrainian intercontinental ballistic missile. A draft project of the 15Zh52 MIRV train-based version of the RT-23 was completed in June 1980. The system was designed to allow the mobile launchers to conduct long-duration deployments up to 200 km from base. More...
RT-23U 15Zh61 Ukrainian intercontinental ballistic missile. A decree of 9 August 1982 ordered development of an improved RT-23UTTKh, dubbed 'Molodets'. Three basing modes were to be possible using a single containerised missile: train-launched, a 'Tselina-2' road-mobile transport, or silo-based. This would be able to deploy up to ten nuclear warheads from a layered circular dispenser. Retired in 2003. More...

N2O4/UDMH Nitrogen tetroxide became the storable liquid propellant of choice from the late 1950's. Unsymmetrical Dimethylhydrazine ((CH3)2NNH2) became the storable liquid fuel of choice by the mid-1950's. Development of UDMH in the Soviet Union began in 1949. It is used in virtually all storable liquid rocket engines except for some orbital manoeuvring engines in the United States, where MMH has been preferred due to a slightly higher density and performance.
