Armament US pattern M2 and M30 107 mm (4.2 in) rifled mortars. Development By PYRKAL, to improve the performance of 4.2 in mortars in Greek service. Description This is to the same general shape as the standard HE bomb for the 107 mm mortar (see USA entry) and uses the same obturation system. It differs in being a cargo bomb, carrying 20 M20G prefragmented dual-purpose submunitions inside the body. The submunitions have a shaped charge for light armour defeat and fragmentation for antipersonnel effects. Each 39 mm
diameter submunition carries 30 g of Composition A5. These are arranged around a central rod which terminates in a plate above the obturation assembly. An expelling charge below the fuze forces down this rod, so shearing off the end of the bomb and then ejects the submunitions. Centrifugal force arms the individual fuzes in the submunitions and disperses them radially from the bomb's trajectory. Delay parachutes slow the descent and stabilise the submunitions so that they fall into the target area. Dispersion radius is approximately 70 to 140 m. On striking an armoured vehicle the shaped charge, within each submunition, will penetrate at least 60 mm of armour; as an anti-personnel munition they will each produce a minimum of 200 fragments with a lethal radius of 15 m against standing troops.
