- Feature Summary
- The Cross Bomb is a ZDR-catalogued compact-form demolition array that sends synchronized charges outward in four cardinal paths from a transformed armor sphere.
- Technical Profile
- A compact-form release controller, directional sequencer, and localized containment system that converts a stationary placement into a four-way blast pattern.

System Overview
The Cross Bomb operates through controlled symmetry. After deployment from compact-form armor, its sequencer sends four related charges along the cardinal axes, producing a cross-shaped blast pattern rather than a single radial detonation.
That geometry lets the system address tunnel junctions, aligned barrier seams, and distributed receivers from one central placement. It is less about maximum explosive force than about placing force in four predictable directions.
The pattern leaves a distinctive scene signature: directional scoring and fracture lines extend outward from a central point, allowing technicians to distinguish the array from a conventional bomb even after partial collapse.
Technology And Function
The release controller first confirms that the host form is stable, then hands timing to the directional sequencer. Each outgoing path needs enough containment to remain useful in a confined volume without reflecting destructive pressure directly into the center.
A timing error changes the array's character. If one arm fires early, it can damage the material that guides another; if a path is obstructed, the resulting reflected pressure can make the remaining axes unpredictable.
Dense rock, fluid-filled tunnels, and pre-fractured infrastructure alter blast propagation. The device is therefore coupled as much to local geometry as to its own charge rating.
Application And Uses
The Cross Bomb is appropriate for an aligned set of brittle barriers or receivers where individual placement would expose the operator to repeated handling risk. One placement can test or clear multiple directions at once.
In collapsed infrastructure, the pattern can reveal voids and weak joins through the way its fracture arms stop, bend, or vent. That makes it useful for route assessment when the area has first been cleared of vulnerable material.
It should not be used as a casual crowd-clearing device. Four blast paths reach farther than the central placement suggests, and unobserved side passages can turn a controlled array into a broader structural failure.
Placement And Structural Survey
The central placement determines all four blast paths, making orientation a safety decision rather than a minor aiming correction. Before deployment, the operator should identify cardinal exits, voids behind the visible wall, loose ceiling material, and any route through which pressure can return toward the compact-form armor. A one-axis obstruction can redirect force into the other three arms and defeat an otherwise correct pattern.
Post-blast survey should begin at the center and move outward along each arm separately. Differences in fracture length, residue density, and venting reveal hidden changes in material or an interrupted sequence. That information is valuable for route mapping, but only if debris is left in place long enough to distinguish the four original paths.
