The Zenit-2 launch vehicle marked the beginning of development and successful operation of the Zenit family that features high performance capabilities, structural and weight efficiency, high assembly density, and operational safety.

The Zenit-2 is a two-stage launch vehicle using non-toxic propellants: liquid oxygen and RG-1 kerosene. The rocket is used for launching spacecraft into low circular (up to 1500 km) and elliptical Earth orbits.

The Zenit-2 design can accommodate spacecraft of any types and characteristics. Using cutting-edge technologies enabled to provide fully automated launch operations. 

The Zenit-2 was first launched on April 13, 1985. In 1985-2004, 36 launches were performed, 31 of which successful. Moreover, modified first stages of the Zenit-2 were used as strap-on boosters in the Energia launch vehicle and performed successfully in two missions (8 boosters in all). 

Today, the Zenit-2 is no longer in service, its functions assigned to the Zenit-2SLB launch vehicle.
