Weapons, weapon components and related methods are provided. In one
embodiment a weapon component includes one or more discrete fragments
embedded in a reactive material matrix. The weapon component may be used
as a warhead that includes an explosive charge. In one embodiment the
weapon component is configured such that, upon explosive launch, the
reactive material matrix fractures to define one or more reactive
material matrix fragments. The weapon component may be configured such
that the discrete fragments are propelled at a first velocity over a
defined distance while the reactive material matrix fragments are
propelled at a second velocity over the defined distance, the second
velocity being less than the first velocity. The weapon component may be
used, for example, in a countermeasure weapon used to defeat a target
weapon. Other embodiments of weapon components, weapons and related
methods are also disclosed.
