==Warheads== Hydra 70 warheads fall into three categories: * Unitary warheads with impact-detonating fuzes or remote-set multi-option fuzes. * Cargo warheads with [[air burst]]-range, with settable fuzes using the "wall-in-space" concept or fixed standoff fuzes. * Training warheads. ===Fuzing options=== {|class="wikitable" style="font-size:96%;" ! # !
