Abstract A multi-purpose bomblet is designed for accomplishing various military mions. A standoff spike and shaped charged are provided for piercing heavy armor and a fragmentation case surrounds the shaped charge. Upon detonation of the shaped charge, the fragmentation case disintegrates to provide shrapnel which is effective against personnel. An inner liner of incendiary material also surrounds the shaped charge and, upon detonation of the shaped charge, the incendiary material is ignited and dispersed and is useful for starting fires.
