The Dnepr LV is intended for timely high-accurate injection of a single spacecraft
(SC) or a group of various SCs with total mass of up to 3.7 t into the near-Earth
orbits of 300-900 km altitude and 50.5°, 64.5°, 87.3°and 98° inclination.
It is created on the basis of the most powerful in the world ICBM RS-20 (SS-18 Satana)
having high power capability and reliability confirmed by 160 launches (including 8 launches
under the Dnepr program). The design scheme of RS-20 missile
and invariance of the control system have allowed creation on its basis of the
high-effective launch vehicle that meets the current requirements for the SC
injection means.
The following main principles are realized during creation of the Dnepr LV:
- maximum utilization of earlier designed and developed systems and components
of RS-20 Complex;
- application of proven technological procedures;
- utilization of existing LV flight routes with impact regions for separating
parts and payload fairing.
The Complex is able to provide up to 25 launches per year.
Being installed into a silo and filled with propellants, the LV may stay unlimited
time, within the service life, in the launch device before integration of the
space payload with SC or with attached space payload. The replacement of the
SC (space payload) does not require propellant discharge and LV removal out
of the launch device.

Significant fleet of rockets (~ 150 pcs), LV long service life, infrastructure of the Technical and Launch Complexes at the Baikonur Space Center ", available impact regions for LV separating parts, ground Measurement Complex and existing cooperation between
enterprises-manufacturers of the Dnepr ILV ensure stable launch service on SCs injection.
