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.
