Blizzard is superior to the American space shuttle in some technical aspects, mainly as follows: First, the main engine of the space shuttle is on the energy rocket, which greatly reduces the weight of the space shuttle in orbit. Although slightly larger than the American space shuttle, it has reduced its weight by about 5 tons and can carry more payloads.

Second, the "energy" rocket has many functions with one arrow, which can launch both the space shuttle and other spacecraft, meeting the needs of the Soviet space arms race at that time. Moreover, the "energy" rocket can be recycled in sections and reused to improve efficiency.

Third, both the first and second stages of the "Energy" rocket use liquid propellant, so the reliability of the rocket is high. Moreover, if the space shuttle Blizzard breaks down, it can use its own motor engine to make the space shuttle enter a lower orbit or return to the launch site immediately, which greatly improves the safety performance of the space shuttle.

Fourth, although there is no main engine on the space shuttle Blizzard, there are two small motor engines. If the first landing fails, it can be pulled up and landed again like an ordinary plane with high safety performance.

Fifth, when the "blizzard" runs in orbit, it relies entirely on unmanned automatic driving, which is more technically difficult.
