About
The Mayak-M-3.9 is a two-stage heavy-lift class launch vehicle developed by Yuzhnoye SDO, utilizing RD815 engines on the first stage and technologies derived from the proven Zenit, Cyclone, and Antares rockets. Designed in both monoblock and modular configurations, it targets commercial and governmental payloads destined for low Earth orbit, geostationary transfer orbit, and lunar trajectories. The vehicle employs liquid oxygen and kerosene propellants on both stages, offering an environmentally friendlier alternative to storable-propellant rockets. With a body diameter of 3.9 meters and a fairing diameter of 4.2 meters, it fits within the established ground infrastructure footprint of existing Ukrainian launch systems.
