A portable launcher stage (MLP), otherwise called versatile dispatch stage, is a structure used to help an enormous multistage space vehicle which is gathered (stacked) vertically in a reconciliation office (for example the Vehicle Assembly Building) and afterward shipped by a crawler-carrier (CT) to a platform. This turns into the help structure for dispatch. Options in contrast to this strategy incorporate even gathering and transport to the cushion, as utilized by Russia; and amassing the vehicle vertically on the platform, as the United States utilized for littler dispatch vehicles.
The utilization of portable launcher stage is an aspect of the Integrate-Transfer-Launch (ITL) framework, which includes vertical get together, transport, and dispatch of rockets.
