A lethality device includes a penetrator structure configured to penetrate
a target and an incendiary material disposed near the penetrator
structure. The incendiary material self-ignites and is injected into the
target after penetration of the target. A projectile includes a
penetrator structure configured to penetrate a target, an incendiary
material disposed near the penetrator structure, and one or components
other than the penetrator structure and the incendiary material disposed
aft of the penetrator structure. Loads from the one or more components
are transferred to the penetrator structure upon impact with the target.
The incendiary material self-ignites and is injected into the target
after penetration of the target. A method for defeating a target
containing an ignitable material includes broaching or puncturing an
outer skin of the target, self-igniting an incendiary material, injecting
the ignited incendiary material into the target, and igniting a material
disposed within the target.
