The P4 ASPIC, which provided with the base to be modified, was a P4 light liaison vehicle fitted with a reinforced chassis, designed to carry an ASPIC short-range anti-aircraft weapon system. Of the 24 P4 ASPIC vehicles in service with the French Air and Space Force, 19 were to be converted into P4 VIPAIRs, the other 5 being kept in reserve for other uses.
The P4 VIPAIR was to be equipped with a multi-purpose platform and weapon mounts, enabling it to carry out liaison and intervention missions for the French Air and Space Force.
