## Abstract

A fuse booster system for a reduced collateral damage bomb or penetrating warhead is described and disclosed. The fuse booster system uses shaped charges that will ignite the main high explosive charge of the bomb or penetrating warhead, and also remove portions of the bomb or penetrating warhead to reduce the power of the bomb at the target in a measurable manner to control the lethality and collateral damage of the bomb or penetrating warhead.

## Claims

### Claim 1

A fuse booster assembly for use in selectively detonating a bomb, comprising:
(A) a fuse assembly casing;
(B) a first end support for closing a first end of the fuse assembly casing;
(C) a second end support for closing a second end of the fuse assembly casing;
(D) at least one first shaped charge that is forward directed for initiating a main explosive charge of the bomb;
(E) at least one first shaped charge support that includes the at least one first shaped charge;
(F) at least one second shaped charge that is aft directed that when initiated before the at least one first shaped charge will remove at least a portion of an aft end of the bomb to lessen an explosive capability the bomb to reduce collateral damage of the bomb;
(G) at least one second shaped charge support that includes the at least one second shaped charge; and
(H) a shaped charge support holder for disposing therein the at least one first shaped charge support that includes the at least one first shaped charge and the at least one second shaped charge support that includes the at least one second shaped charge such that the at least one first shaped charge support that includes the at least one first shaped charge and the at least one second shaped charge support that includes the at least one second shaped charge include having the at least second shaped charge support that includes the at least one second shaped charge adjacently disposed radially outward from the at least first shaped charge support that includes the at least one first shaped charge and other than along a longitudinal axis of the fuse booster assembly.

### Claim 2 (depends on 1)

The fuse booster assembly as recited in claim 1, wherein within the shaped charge support holder, the at least one first shaped charge support and the at least one second shaped charge support include being adjacently disposed substantially perpendicular to a longitudinal axis of the fuse booster assembly a predetermined distance from a forward end of the fuse assembly casing.

### Claim 3 (depends on 2)

The fuse booster assembly as recited in claim 2, wherein the at least one first shaped charge is disposed in the at least one first shaped charge support in the shape charge support holder such that when initiated a jet formed by the at least one first shaped charge is directed forward in a direction substantially parallel to a longitudinal axis of the fuse booster assembly.

### Claim 4 (depends on 3)

The fuse booster assembly as recited in claim 3, wherein the at least one first shaped charge is disposed in the at least one first shaped charge support in the shape charge support holder such that when initiated a jet formed by the at least one first shaped charge is directed forward in a direction substantially along the longitudinal axis of the fuse booster assembly.

### Claim 5 (depends on 2)

The fuse booster assembly as recited in claim 2, wherein the at least one second shaped charge is disposed in the at least one second shaped charge support in the shape charge support holder such that when initiated a jet formed by the at least one second shaped charge is directed aft in a direction that is at an angle to a longitudinal axis of the fuse booster assembly.

### Claim 6 (depends on 1)

The fuse booster assembly as recited in claim 1, wherein within the shaped charge support holder, the at least one first shaped charge support and the at least one second shaped charge support include being disposed in substantially a same plane perpendicular to a longitudinal axis of the fuse booster assembly.

### Claim 7 (depends on 6)

The fuse booster assembly as recited in claim 6, wherein the at least one first shaped charge is disposed in the at least one first shaped charge support in the shape charge support holder such that when initiated a jet formed by the at least one first shaped charge is directed forward in a direction substantially parallel to a longitudinal axis of the fuse booster assembly.

### Claim 8 (depends on 7)

The fuse booster assembly as recited in claim 7, wherein the at least one first-shaped charge is disposed in the at least one first shaped charge support in the shape charge support holder such that when initiated a jet formed by the at least one first shaped charge is directed forward in a direction substantially along the longitudinal axis of the fuse booster assembly.

### Claim 9 (depends on 6)

The fuse booster assembly as recited in claim 6, wherein the at least one second shaped charge is disposed in the at least one second shaped charge support in the shape charge support holder such that when initiated a jet formed by the at least one second shaped charge is directed aft in a direction that is at an angle to a longitudinal axis of the fuse booster assembly.
