Instalaza SA developed this cargo bomb which was type-classified by the Spanish Ministry of Defence in 2002. It was intended to be co-produced by Patria for the Finnish defence forces from 2007. However, in spite of this being the only mortar cargo bomb that has demonstrated 0 per cent of hazardous duds, the MAT-120 is considered a cluster bomb and is therefore banned under the 2008 Dublin agreement on cluster munitions.
Description
The MAT-120 cargo mortar bomb is fired from 120 mm smoothbore mortars and carries 21 submunitions, each of 37 mm diameter, up to a range of 5,500 m to 6,800 m, depending on the barrel length.The MAT-120 incorporates an electronic safety-and-arming system. When stored, the round does not contain any electrical energy. The main fuze generates all necessary power after firing, once the round is in flight.Each submunition has its own electronic SuperQuick (SQ) impact fuze. The fuze controls activation after submunition scattering, initiating the submunition warhead on impact. The submunition fuze includes a Self-Destruction Self-Deactivation [sD]² device which assures its self destruction after 20 seconds, or its self-deactivation after a few minutes, thereby achieving a 0 per cent hazardous dud rate, which exceeds the Geneva's Protocol II requirements. Each submunition is dual-purpose: both anti-armour, penetrating up to 150 mm of Rolled Homogeneous Armour (RHA), and anti-personnel, carrying about 650 fragments per submunition, with an 18 m effective radius.The safety-and-arming system ensures not only safety during storing, handling, firing and flight, but also reliability of the submunitions on impact and a safe target zone some minutes after firing.The MAT-120 bomb is fired in the same way as any conventional mortar round and does not require specific training. After firing, and once the time preset in the fuze has been reached, the round spreads the submunitions to fall freely in a near-vertical trajectory, reaching the target in a uniform pattern covering a circle some 50 to 60 m in
