Fitted For Wireless (FFW) and Fitted For Radio (FFR) were British Army designators for vehicles equipped to carry radio equipment. Although many of these vehicles would be dedicated 'radio vans' and would have the complex and expensive radio sets installed, the intention was also that general purpose vehicles could be issued in 'FFW' state with the low-cost but time-consuming cabling and equipment mounts already prepared. The actual sets themselves could be installed later, if a new radio vehicle was required owing to damage or breakdown.
