Mayak (rocket family)

Mayak is a new family of Ukrainian launch vehicles under development by the Pivdenne, which would be manufactured by Pivdenmash.

History The family is built in a modular fashion on the basis of a single line of main engines with thrust of roughly for the first stage (RD-801 or RD-810) and for the upper stage (RD-809K derived from RD-8). Engines, control systems and ground equipment are largely derived from components of existing rocket families Zenit and Tsyklon.
