Abstract
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 Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
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.
Claim 2
Dependent Claim
150 words
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.
Claim 3
Dependent Claim
36 words
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.
Claim 4
Dependent Claim
38 words
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.
Claim 5
Dependent Claim
35 words
