An unmanned aerial vehicle line charge deployment system includes an unmanned aerial vehicle, a payload bay mounted beneath the unmanned aerial vehicle, and a line charge release subsystem coupled to the payload bay. A first line charge release mechanism releasably secures a first portion of a line charge to the unmanned aerial vehicle payload bay and a second line charge release mechanism, independent from the first line charge release mechanism, releasably secures a second portion of the line charge to the unmanned aerial vehicle payload bay.

A deployable, linear explosive structure includes a split tube, an explosive coupled to the split tube, and a fragmentable or non-fragmentable projectile disposed with respect to the explosive. The split tube can be rolled into a non-deployed state in which the split tube has a flat, rolled profile. The split tube also can be deployed from the non-deployed state to a deployed state in which the split tube is extended along its length and has a curved cross-section along its length. The split tube provides support of the explosive structure in the deployed state. The split tube also provides smaller storage and transportation volume for the explosive structure when rolled in the non-deployed state.
