Mayak (rocket family) 
Summary
Mayak is a new family of Ukrainian launch vehicles under development by the Pivdenne,[1][2] which would be manufactured by Pivdenmash.
The family is built in a modular fashion on the basis of a single line of main engines with thrust of roughly 120 or 200 tonnes-force (1,200 or 2,000 kN) for the first stage (RD-801 or RD-810) and 10 tonnes-force (98 kN) 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.
The Mayak family is designed to cover small-lift, medium-lift and heavy-lift requirements. Published parameters of various configurations are:[2]
