Abstract

A weapon and weapon system, and methods of manufacturing and operating the same. In one embodiment, the weapon includes a warhead including destructive elements and a guidance section with a target sensor configured to guide the weapon to a target. The target sensor includes a front lens configured to provide a cover to protect the target sensor from an environment and a fast fresnel lens behind the front lens to provide a multi-lens focusing system for the target sensor. In a related embodiment, the weapon includes an aft section including a tail fin having a modifiable control surface area thereby changing an aspect ratio thereof.

Claims

1. A weapon, comprising:

a warhead; and

an aft section including a tail fin having a modifiable control surface area thereby changing an aspect ratio thereof.

2. The weapon as recited in claim 1 wherein said tail fin has an extendable surface or a retractable surface to modify said control surface area.

3. The weapon as recited in claim 1 wherein said tail fin has a deformable surface to modify said control surface area.

4. The weapon as recited in claim 1 wherein said tail fin has a deformable surface coupled to a rod, pin and dowel configured to extend or retract said deformable surface within or without said tail fin to modify said control surface area.

5. The weapon as recited in claim 1 further comprising a folding lug switch assembly configured to provide a mechanism to attach said weapon to a delivery vehicle, arm said warhead, or enable weapon guidance systems associated with a guidance section of said weapon.

6. The weapon as recited in claim 1 further comprising an antenna configured to receive instructions after launching from a delivery vehicle to guide said weapon to a target and receive mission data before launching from said delivery vehicle to guide said weapon to said target.

7. The weapon as recited in claim 1 further comprising a guidance section with a target sensor configured to guide said weapon to a target, including:

a front lens configured to provide a cover to protect said target sensor from an environment, and

a fast fresnel lens behind said front lens configured to cooperate with said front lens to provide a multi-lens focusing system for said target sensor.

8. The weapon as recited in claim 1 wherein said warhead includes destructive elements formed by non-explosive materials.

9. The weapon as recited in claim 1 wherein said aft section includes flight control elements and power elements.

10. The weapon as recited in claim 1 wherein said weapon is a Mark-76 derived weapon or a bomb dummy unit (BDU)-33 derived weapon.

11. A method of operating a weapon, comprising:

providing a warhead;

modifying a control surface area to change an aspect ratio of a tail fin when guiding said weapon to a target.

12. The method as recited in claim 11 wherein said tail fin has an extendable surface or a retractable surface to modify said control surface area.

13. The method as recited in claim 12 further comprising employing a folding lug switch assembly for at least one of the following:

providing a mechanism to attach said weapon to a delivery vehicle,

arming said warhead, and

enabling weapon guidance systems associated with said guidance section.

14. The method as recited in claim 11 further comprising guiding said weapon to said target with a guidance section having a target sensor, including:

a front lens that provides a cover to protect said target sensor from an environment, and

a fast fresnel lens behind said front lens that cooperates with said front lens to provide a multi-lens focusing system for said target sensor.

15. The method as recited in claim 11 further comprising receiving mission data via an antenna of said weapon before launching from a delivery vehicle and receiving instructions via said antenna after launching from said delivery vehicle to guide said weapon to said target.

16. A method of manufacturing a weapon, comprising:

providing a warhead; and

providing an aft section including a tail fin having a modifiable control surface area thereby changing an aspect ratio thereof.

17. The method as recited in claim 16 wherein said tail fin has an extendable surface or a retractable surface to modify said control surface area.

18. The method as recited in claim 16 further comprising providing a folding lug switch assembly projecting from a surface of said weapon that provides a mechanism to attach said weapon to a delivery vehicle.

19. The method as recited in claim 16 further comprising providing a guidance section having a target sensor, including:

a front lens that provides a cover to protect said target sensor from an environment, and

a fast fresnel lens behind said front lens that cooperates with said front lens to provide a multi-lens focusing system for said target sensor.

20. The method as recited in claim 16 further comprising providing an antenna about a surface of said weapon configured to receive mission data before launching from a delivery vehicle and receive instructions after launching from said delivery vehicle to guide said weapon to a target.

21. A weapon system, comprising:

a delivery vehicle; and

a weapon, including;

a warhead,

a guidance section configured to guide said weapon to a target, and

an aft section including a tail fin having a modifiable control surface area thereby changing an aspect ratio thereof.

22. The weapon system as recited in claim 21 wherein said tail fin has an extendable surface or a retractable surface to modify said control surface area.

23. The weapon system as recited in claim 21 wherein said weapon further includes a folding lug switch assembly employable for at least one of the following:

providing a mechanism to attach said weapon to said delivery vehicle,

arming said warhead, and

enabling weapon guidance systems associated with said guidance section.

24. The weapon system as recited in claim 21 wherein said guidance section has a target sensor, including:

a front lens that provides a cover to protect said target sensor from an environment, and

a fast fresnel lens behind said front lens that cooperates with said front lens to provide a multi-lens focusing system for said target sensor.

25. The weapon system as recited in claim 21 wherein said weapon further includes an antenna configured to receive mission data before launching from said delivery vehicle and receive instructions after launching from said delivery vehicle to guide said weapon to said target.
