Based on more than 50 years of experience in the industrial maintenance of military vehicles, FFG developed their first M113 modernization concept more than 25 years ago. Our customers appreciate the intelligent and combat proven FFG solutions to equip their existing vehicles with modern protection systems and considerably better mobility.


The additional payload of the M113 by increasing the length of the hull and the raising of the ceiling increases the possible use of the modernized vehicles for a further 20 to 30 years. To date the FFG has modernized more than 1,500 M113 vehicles in the different configurations and have always fulfilled the individual requirements of each customer. Naturally the FFG makes sure that the existing equipment sets can continue to be used and regularly takes on the modernization of the equipment sets.
