Vehicle preparation bays have been designed by the LSDF as an area where vehicles can be given last minute work by engineering and launch crews prior to deployment. In vehicle preparation bays ammunition is loaded onto a vehicle, weapon systems are charged, warheads are put in a live state, and personal pilot data and equipment can be loaded onto a vehicle. Vehicle preparation bays are serviced by engineering crews, launch bay crews, and mechanical arm systems. Vehicles are moved to and from the vehicle preparation bay by vehicle lift systems.
