@Erdayastronaut @LevEakins More accurate word is “propellant”, rather than “fuel”. Starship is ~78% liquid oxygen, ~22% fuel.
Propellant cost is of primary importance for a fully reusable rocket, so reusable rockets want high thrust, as thrust below T/W of 1 is irrelevant.
@埃尔达亚斯特罗诺@利维金斯更准确的词是“推进剂”，而不是“燃料”。星际飞船大约78%是液氧，22%是燃料。
推进剂成本对于完全可重复使用的火箭至关重要，因此可重复使用的火箭需要高推力，因为低于1吨/瓦的推力无关紧要。
