Integrated Launch Vehicle Zenit-3SL
Integrated Launch Vehicle (ILV) Zenit-3SL consists of: launch vehicle Zenit-2S, upper stage Block DM-SL, and Payload Unit containing
a spacecraft. The developers and manufacturers of Zenit-2S launch vehicle are Design Bureau Yuzhnoye and Production
Association Yuzhmashzavod (Dnepropetrovsk, Ukraine). Upper stage Block DM-SL was developed and is mass-produced by
S.P.Korolev RSC Energia (Korolev, Moscow region, Russia) in cooperation with Russian companies. Development of the
payload unit, which includes payload fairing and structural adapters connecting spacecraft to the upper stage, is the
responsibility of Boeing Commercial Space Company (Seattle, Washington, USA)
Integrated Launch Vehicle Zenit-3SL is a state-of-the-art launcher featuring operational simplicity and full automation
of pre-launch processing and launch. It operates on liquid oxygen and kerosene, producing water and carbon dioxide
as combustion products. This makes it environmentally safe. It has been modified to adapt it to sea launch conditions.
ILV Zenit-3SL was developed on the basis of Zenit-2 launch vehicle and upper stage Block DM, that have been in service
for some time, which assures high flight reliability even during its first launches.
