Lox/LH2 upper stages launched by Energia would put 21 tonne communications satellites into geosynchronous orbit. 4 to 6 such satellites would make up a global informaton system, solving congestion problems in geosynchronous orbit. It was felt that only heavy platforms in an integrated sytem could operate high-volume optical inter-satellite data links.
