The system is connectable to a transport truck and includes a trailer, a pivotable canister, a plurality of stabilizing legs, and an equipment module. The trailer has a hitch for connecting to the truck, a base for supporting wheels for road travel, and a flatbed platform having a transverse hinge. The canister contains launcher for at least one missile and is configurable by rotation at the hinge for disposal in either a longitudinal position for stowage or an erected position for deployment. The stabilizing legs are disposed along a periphery of the trailer. The legs can be disposed in one of an elevated position for stowage and a retarded position for ground engagement. The equipment container supplies electrical power, environmental conditioning, tracking, communication and control for the missile.
