Launch vehicle ZENIT-2SLB

The “Zenit-2SLB” launch vehicle (LV) is a further developed “Zenit-2” launch vehicle. It is designed for payload injection to low and medium near-earth orbits with inclination of 51.4 deg, 63.9 deg and 98.9 deg. A payload injection into orbits with different inclination is possible.

The launches are implemented from “Baikonur” cosmodrome.

The two-stage integrated launch vehicle is based on first two stages of LV Zenit-3SL, used in the Sea Launch program (designed by Yuzhnoye SDO).
