Mayak (rocket family)
<templatestyles src="Module:Hatnote/styles.css"></templatestyles>
Mayak is a new family of Ukrainian launch vehicles under development by the Yuzhnoye Design Office,[1][2] which would be manufactured by Yuzhmash. Due to the ongoing political and economic crisis in Ukraine, as of May 2016[update] the feasibility and timetable of the project are unknown.
The family is built in a modular fashion on the basis of a single line of main engines with thrust of roughly 120 to 200 tonnes-force (1,200 to 2,000 kN) for the first stage (RD-801, 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]
