Armament 81 mm TDA and other medium-pressure mortars. Development By Simmel Difesa for use in Italian Army mortars and for export. Description The S6A2 is a parellel-walled bomb with an aluminium alloy body in two parts. The ogive and straight section form the principal unit and carry the time fuze, expelling charge, pusher plate and nine submunitions. The rear section is the tailcone of the body and is a push-fit into the forward section which is retained by shear pins. An extruded alloy tail unit screws into the
end of the body. A primary cartridge fits into the tailboom and six secondary charges fit around the boom, ahead of the fins, in horseshoe containers. The bomb is drop-fired in the usual way, the time fuze being set to produce a burst 400 m above the ground at the desired range. When the fuze functions, it ignites the expelling charge; this presses on the pusher plate and the payload and, shearing the retaining pins, throws off the body tailcone and tail assembly. An explosive ejector then ejects the submunitions and disperses them around the trajectory so as to fall roughly in an ellipse of overlapping lethal zones about 50 × 20 m. Each submunition weighs 140 g, is 34 mm in diameter and 77 mm long and contains a 25 g Composition A5 shaped charge capable of penetrating 60 mm of armour. In addition there is a 5 m lethal area of fragmentation around the point of impact. Manufacturer Simmel Difesa SpA.
