A missile includes one or more arrays of barrel assemblies that are displaced
from
the centre of gravity of missile. Each barrel assembly includes a plurality of
projectiles axially disposed within a barrel, and each projectile is associated
with a discrete propellant charge for propelling the projectile sequentially from
the barrel. Each array of barrel assemblies is capable of selectively firing the
projectiles from selected barrels, whereby the missile is accelerated by the reactionary
force generated by said firing of projectiles and the missile is deflected onto
a new course or trajectory. This enables the missile to be steered to intercept
its target, even if the target is undertaking evasive manoeuvres. Each barrel assembly
may include multiple projectiles.
