Kinetic energy rod warhead with lower deployment angles

Abstract

This invention features a kinetic energy rod warhead including a projectile core including a plurality of different size projectiles, an explosive charge about the core, and at least one detonator for the explosive charge.

Description

RELATED APPLICATIONS [0001] This application is a Continuation-in-Part application of U.S. patent application Ser. No. 10 / 456,777, filed Jun. 6, 2003 which is a Continuation-in-Part of U.S. patent application Ser. No. 09 / 938,022 filed Aug. 23, 2001, issued on Jul. 29, 2003 as U.S. Pat. No. 6,598,534 B2.FIELD OF THE INVENTION [0002] This invention relates to improvements in kinetic energy rod warheads. BACKGROUND OF THE INVENTION [0003] Destroying missiles, aircraft, re-entry vehicles and other targets falls into three primary classifications: “hit-to-kill” vehicles, blast fragmentation warheads, and kinetic energy rod warheads. [0004]“Hit-to-kill” vehicles are typically launched into a position proximate a re-entry vehicle or other target via a missile such as the Patriot, THAAD or a standard Block IV missile. The kill vehicle is navigable and designed to strike the re-entry vehicle to render it inoperable. Countermeasures, however, can be used to avoid the “hit-to-kill” vehicle. Mo...

Benefits of technology

[0014] It is a further object of this invention to provide such a kinetic energy rod warhead which prevents the projectiles from breaking when they are deployed.

[0026] This invention further features a kinetic energy rod warhead including a projectile core including a large number of smaller projectiles for increasing the lethality against submunition payloads and a small number of larger projectiles for increasing lethality against bomblet payloads, an explosive charge about the core, and at least one detonator for the explosive charge.

Problems solved by technology

Moreover, biological warfare bomblets and chemical warfare submunition payloads are carried by some threats and one or more of these bomblets or chemical submunition payloads can survive and cause heavy casualties even if the “hit-to-kill” vehicle accurately strikes the target.

Blast fragmentation type warheads, unlike “hit-to-kill” vehicles, are not navigable.

The fragments, however, are not always effective at destroying the target and, again, biological bomblets and / or chemical submunition payloads survive and cause heavy casualties.

To date, however, kinetic energy rod warheads have not been widely accepted nor have they yet been deployed or fully designed.

The cylindrical shaped projectiles, however, may tend to break and / or tumble in their deployment.

Still other projectiles may approach the target at such a high oblique angle that they do not effectively penetrate the target.
