 The tungsten housing is designed to fragment and produce maximum damage inside the target.A demonstration was conducted in September 1999 that showed the missile being used against an FV432 armoured personnel carrier, showing the missile's effectiveness as a surface-to-surface weapon.Each sub-munition dart travelling at 4,500 km/h (1,250 m/s, 4,100 ft/s, 2,800 mph) has comparable kinetic energy to a shell from a Bofors 40 mm gun and probably has sufficient energy to penetrate the front armour of an infantry fighting vehicle.
