HE MOM is a multirole ammunition in which preformed cubes of tungsten alloy are held in position around the projectile body by steel liners and able to pierce up to 6mm steel. The new proximity fuse makes the projectile very effective also in the anti-ship role. When the proximity function is paralysed, the fuse has a delayed PD action which ensures that the projectile penetrates the hull before bursting.
