## Abstract

A detachable blast structure for use as an underbelly device of a personnel cabin for a vehicle, is disclosed. The blast structure comprises at least one modular section attachable to the underbody, and means for attaching and detaching the modular sections to the underbody. The modular sections are separately attachable and detachable from portions of the vehicle as needed, depending on the situations and environment the vehicle will be exposed to and the level of protection required.

## Claims

### Claim 1

A detachable blast structure for use as an exterior underbody protection for a personnel cabin for a vehicle, the structure comprising:
at least one modular section attachable to a side of the underbody;
means for attaching and detaching the modular sections to the underbody.

### Claim 2 (depends on 1)

The detachable blast structure of claim 1, wherein the modular sections are comprised of at least one material selected from the group consisting of a high-strength low-alloy steel, a hardened aluminum, or a high carbon steel.

### Claim 3 (depends on 1)

The detachable blast structure of claim 1, wherein an air gap is formed between the attached modular sections and the interior of the cabin.

### Claim 4 (depends on 1)

The detachable blast structure of claim 1, wherein an air gap is formed between the attached modular sections and a blast center.

### Claim 5 (depends on 1)

The detachable blast structure of claim 1, wherein the means for attaching and detaching comprises a fastener.

### Claim 6 (depends on 5)

The detachable blast structure of claim 5, wherein a blast load is transferred between the detachable blast structure and the cabin through the use of a load transfer comb/key component.

### Claim 7 (depends on 1)

The detachable blast structure of claim 1, further comprising at least one exterior shield structure formed within at least one modular section.

### Claim 8

An armored blast system for attachment to and detachment from a vehicle having a cabin hull, the system comprising:
a plurality of modular panels attachable to and removable from a portion of the cabin hull; and,
a means for attaching and detaching the panels.

### Claim 9 (depends on 8)

The armored blast system of claim 8, wherein the modular panels are comprised of a multi-layered structure.

### Claim 10 (depends on 9)

The armored blast system of claim 9, wherein the modular panels are separately attachable to the cabin hull.

### Claim 11 (depends on 10)

The armored blast system of claim 10, wherein the modular panels are separately attachable to an underbody of the cabin hull.

### Claim 12 (depends on 10)

The armored blast system of claim 10, wherein the modular panels are separately attachable to a blast center of the cabin hull.

### Claim 13 (depends on 8)

The armored blast system of claim 8, wherein the means for attaching and detaching the panels include fasteners.

### Claim 14 (depends on 8)

The armored blast system of claim 8, further comprising at least one exterior shield structure formed within the modular panels.

### Claim 15

An armored blast protection system for attachment to and detachment from a vehicle having a cabin hull, the system comprising:
a plurality of modular panels attachable to and removable from a portion of the cabin hull;
a means for attaching and detaching the panels; and,
a comb and wedge fastening system, wherein a blast load is transferred between the modular panels and the cabin hull through the comb and wedge fastening system.
