Fixed and removable walkways are positioned on the launch vehicle to allow safe and
easy access for tasks to be carried out.
The fixed walkways are attached to section three of the slide frame.
Fixed walkways are also attached to the crane sub frame. This allows access down
the center of the vehicle.
Removable walkways are stored between the launch vehicle chassis rails and on top
of the fixed walkways beneath the launch frame. These walkways are arranged on the
launcher once it has been fully deployed.
