- The Land Launch Zenit rocket consists of either two or three in-line, liquid oxygen (LOX) and kerosene stages. The
three-stage Zenit-3SLB configuration launches to medium and high, circular or elliptical orbits, including GTO and GEO, as
well as escape trajectories. The twostage Zenit-2SLB configuration is used for low-earth circular and elliptical missions.
- The Zenit rocket is manufactured by PO Yuzhmash in Ukraine, with design oversight provided by SDO Yuzhnoye. Significant
configuration differences between the heritage Zenit-2 and the Sea Launch Zenit-2S, which are also retained on the Land Launch
Zenit-2SLB, are:
- New navigation system;
- Next generation flight computer;
- Increased performance due to mass reductions and an increase in second stage main engine thrust.
