| − | The '''launch vehicle''' is the initially working part of a rocket (or any other vehicle), which lifts and accelerates the [[craft]] from the [[launchpad]] to low [[orbit]] (or near to that state). To ensure this amount of thrust usually [[rocket engine]]s are applied (although [[jet engine]]s can be used too, but these are not able to achieve stable orbit alone), enhanced with liquid or [[solid rocket booster]] placed on [[decoupler]]s, in case of liquid fuel boosters, [[asparagus staging]] gives a further enhancement. If we interpret the therm widely, an [[SSTO]] [[spaceplane]] capable to carry [[payload]]s is a launch vehicle too.

| − | The power and the efficiency of a launch vehicle is measured in mass of the payload can be transferred to [[LKO|low orbit]], and the ratio of this mass and the whole starting mass. In case of [[Kerbin]], a launch vehicle with proper construction needs 4200-4700 m/s [[delta-v|Δv]] to reach the stable orbit, and the payload ratio is about 15-20%. In the real world, 1% payload ratio is quite acceptable.
