Abstract

An armor-piercing tandem projectile adapted for multi-layered armored targets. Two armor-penetrating devices are incorporated in the body of the tandem shell projectile which differentiate each other with respect to their moments of impact; the rear armor-penetrating device incorporates a shaped hollow explosive charge including a cavity lining forming an armor-penetrating spike (projectile with high initial velocity) upon detonation. The forward armor-penetrating device has a pointed end with an axial conduit which is in communication with the hollow explosive charge and serves as a passageway for said spike.

Claims

1. An improved armor-piercing tandem projectile particularly adapted for piercing multi-layered armored targets and having a shell body incorporating at least two armor-piercing means which differentiate each other at least with respect to their moments of impacting the target, the rearmost one of the armor-piercing means including a shaped hollow explosive charge;

the improvement comprising;

a first most forwardly disposed armor-piercing means, relative to the target, having the first, in point of time, impacting moment of said armor-piercing means, acting by its kinetic energy;

a second most rearwardly disposed armor-piercing means having a chamber;

said first and second armor-piercing means being rigidly secured to each other,

shaped hollow explosive charge means operatively mounted in said chamber, said shaped hollow explosive charge means including spike forming means;

said first armor-piercing means being formed as an impact body which has a fowardly extending conduit in communication with said shaped hollow explosive charge means.

2. The improvement in an armor-piercing tandem projectile as set forth in claim 1, wherein said impact body has a pointed forward end, said conduit having an outlet in the pointed forward end of said impact body.

3. The improvement in an armor-piercing tandem shell or projectile as set forth in claim 2, wherein said impact body has a pointed forward end, at least a portion of said pointed forward end being formed of metal carbide.

4. The improvement in an armor-piercing tandem projectile as set forth in claim 3, wherein said armor-piercing shell or projectile is of a subcalibre type and includes exchangeable sabot means operatively mounted on said subcalibre projectile.

5. The improvement in an armor-piercing tandem projectile as set forth in claim 4, wherein said subcalibre projectile further includes wing stabilizing means operatively mounted on said shell body.

6. The improvement in an armor-piercing tandem projectile as set forth in claim 3, wherein said impact body includes streamlined projections extending therefrom.

7. The improvement in an armor-piercing tandem projectile as set forth in claim 6, including an additional payload operatively mounted in said shell body behind said hollow explosive charge means.

8. The improvement in an armor-piercing tandem projectile as set forth in claim 7, wherein said payload includes materials selected from the group of incendiary, marking and smoke generating substances.
