A lightweight system for vulnerability reduction is provided by a louvered buffer system. Louvres are made of either thin metal, such as aluminum, or composite materials such as fiberglass compounds or epoxy-fiber material. The louvres are spaced in sufficient proximity, such that upon over pressure on one side of the louvres a rigid cover over the louvres provides a pressure surface area which collapses provides a pressure surface area which collapses the louvres in such a manner as to cause considerable overlap. Fragment paths prior to the collapse will puncture through the louvres and into the fuel tank along straight paths. After collapse, fuel will have to leak from the fuel tank along the serpentine route of collapsed material which will be time consuming. During this time the blast and resultant fireball from HEI will have dissipated. Fuel leakage after removal of the fireball is of minor threat to the aircraft compared to the combustion of leaking fuel. Accordingly, it is an object of the present invention to create a fire prevention system which retards fuel leakage from ruptured fuel tanks until such time as the incendiary effects from modern weaponry have passed.
