Medium-lift tandem launch vehicle
The Zenit-3SLB launch vehicle delivers medium-weight payloads into medium and high circular and elliptical orbits, including geostationary transfer and geostationary orbits, and escape trajectories.
The Zenit-3SLB rocket is a part of the Zenit family, which uses environmentally friendly propellants: liquid oxygen and kerosene RG-1.
The launch vehicle was developed for the Land Launch program to launch spacecraft from Baikonur Cosmodrome, Kazakhstan. The launch system can provide a launch rate of up to 12 launches per year (including up to 7 launches with a booster stage).
The Zenit-3SLB launch services are provided by Space International Services (Ukraine, Russia).
The Zenit-3SLB is derived from the Zenit-3SL launch vehicle. The rocket comprises two stages designed by Yuzhnoye, Block DM-SL booster stage developed by RSC Energia, and a payload unit developed by NPO Lavochkin. The first launch was conducted on April 28, 2008. Six launches were conducted in all, all successful.
