Abstract
This invention provides a subcaliber projectile which is launched from a full bore projectile having a shaped charge warhead prior to impact with the target. The subcaliber projectile is tethered to the full bore projectile by means of a fine electrical cable of fixed length which serves as the communication link between the two projectiles with the length of the cable determining the fuzing standoff distance. The ballistic coefficient of the subcaliber projectile is made such that the subcaliber projectile always flies ahead of the full bore projectile.
Claims14
A round of ammunition of the type fired from a projectile launching device on a ballistic trajectory comprising:
- a first projectile having
- a shaped charge, and
- a fuze for igniting said shaped charge;
- a second projectile coupled to said first projectile and having less drag than said first projectile and
- means for activating said fuze to ignite said shaped charge.
A weapon system comprising:
- a round of ammunition including
- a first projectile having
- a shaped charge, and
- a fuze for igniting said shaped charge;
- a second projectile coupled to and initially carried by said first projectile and having
- means for activating said fuze to ignite said shaped charge;
- said first projectile further including
- means for deploying said second projectile from and forwardly of said first projectile;
- and
- control means, remote from said round of ammunition, for signaling to said first projectile the time of flight at which said deploying means is to deploy said second projectile.
A weapon system comprising:
- a gun;
- a round of ammunition, for being fired from said gun on a ballistic trajectory, comprising:
- a first projectile having
- a charge, and
- a fuze for igniting said charge;
- a second projectile coupled to said first projectile and having
- less aerodynamic drag than said first projectile, and
- means for activating said fuze to ignite said charge;
- said second projectile being initially carried by said first projectile, and
- said first projectile including
- means for receiving a signal originated remotely from said round and for thereupon deploying said second projectile from and forwardly of said first projectile.
A process of detonating a shaped charge in a first projectile at a predetermined distance from a target comprising:
- providing said first projectile with a second projectile which is coupled to said first projectile by cable means of a length equal to said predetermined distance;
- providing said second projectile with relatively less aerodynamic drag than said first projectile;
- disposing said second projectile on board said first projectile;
- accelerating said first and on board second projectile along a ballistic trajectory;
- from a position which is remote from said first and on board second projectile, signaling said projectiles to separate, whereupon said second projectile flies at a higher velocity than said first projectile until limited to the velocity of said first projectile by said length of cable means;
- said second projectile upon impacting the target causing said shaped charge in said first projectile to thereupon detonate.
