    摘要: A 40 mm ammunition projectile for firing without significant spin in an M203 or an M320 grenade launcher. The ammunition includes a projectile body having hollow inner cavity therein for an explosive warhead; a projectile fin assembly; a projectile nose element having a conically shaped front area thereon; a decoupled projectile sabot in two or more joining sabot petals enclosing the body; a base cartridge case having vent holes, a bowl area for placement of a copper closure cup containing propellant therein, and a closure plug for threading into the rear of said cartridge case. The projectile fin assembly may provide a canted angle on each fin blade to (relatively very slowly) spin up the round at less than 30 Hz. Projectiles with body length less than five inches may be launched in an M203 grenade launcher while projectiles with body length up to eight inches may be launched in an M320 grenade launcher.

    摘要: 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.
