A Kinetic Energy penetrator round is shown effective in neutralizing incoming air borne threat munitions such as rockets, artillery, or mortars for instance, without posing a threat in urban environments to harm bystanders on the ground. There are also no hazards or expense with this round of cleaning up unexploded ordnance, which might have occurred with other types of rounds due to unreliability of self destruct mechanisms. Shown herein is a kinetic energy penetrator for air defense that merely self destructs beyond its operational range into fragments that are not lethal to personnel on ground; no pyrotechnic or energetic materials means are used to activate this self destruct process. A full bore projectile structure is shown that is composed of plural axi-symmetric circular disks stacked on each other and tied by a shape memory metal wire of Nitinol. While operational as a joined group, the disks are a formidable round to kill an incoming air target. After the self destruct phase however, each disk is separated from adjacent disks on either side by a spring mechanism that enables separation after the process is initiated in flight when the Nitinol wire deforms due to heating from air drag. Each disk then proceeds alone with low enough terminal kinetic energy on the ground to be less than lethal.

A Hybrid Projectile is provided for delivering an explosive payload to a target wherein the Hybrid Projectile may be steered in flight using relatively inexpensive means. The Hybrid Projectile is exteriorly configured in the same physical exterior configuration of conventional ammunition of various standard types so it can be launched in conventional manner from the same weapon systems. However, internal features allow the Hybrid Projectile to be transformed in flight from a command signal to deploy wings and fins, and in some projectiles to telescope open to deploy such wings and fins. An inexpensive televisual means is activated in the fore region of the round which through RF uplink command can be used to select a path, while motors on the wings can then be used to more precisely glide the projectile to a target, or otherwise to abort the target run.

A flameless tracer and marker for small munitions and canon caliber projectiles incudes non-toxic, environmentally friendly chemiluminescent materials which are maintained in separate compartments is described. The munitions when fired glow intensely for several minutes and mark a target area upon impact.
