Zenit-3SL
Zenit-3SL
Ukrainian orbital launch vehicle. From the beginning of the program a Zenit-3 version was proposed for geosynchronous launches using the N1/Proton Block D third stage. This had the potential of replacing the Proton in the role of geosynchronous launcher. It was considered for launch from Australia / Cape York in the 1980's. Finally a joint US-Norwegian-Ukrainian-Russian consortium was formed to launch the three stage commercial Zenit from the Odyssey floating launch platform in the Pacific Ocean.
