“The new American spacecraft are more than double the weight of a Soyuz while offering only one additional seat,” Rogozin said. He added that the size of the rockets needed to launch Crew Dragon (a SpaceX Falcon 9) or a Starliner (a United Launch Alliance Atlas V) are much heavier than what is required for Soyuz, which uses a medium-class Soyuz-2.1a rocket. He argued that on that comparison, Russian launches remain cheaper than American launches.
