Cyclone-4M
The Cyclone-4M is a Ukrainian carrier rocket that is being developed for commercial satellite launches. The Cyclone-4M is derived from the Tsyklon-4, which started its life as an all-hypergolic three-stage-to-orbit expendable launch vehicle planned for launch from a proposed site at the Alcântara Launch Center in Brazil. However, Brazil backed out of the partnership with Ukraine in 2015, citing concerns over the project budget, the ongoing financial situation in both countries, and the future of the commercial launch market. In March 2017, Canadian company Maritime Launch Services announced plans to begin launching a modified version, the Cyclone-4M, which features a Zenit-derived kerolox (LOX / RP-1) first stage in place of the originally planned R-36 ICBM-based first- and second-stage.
