Abstract
A system for extracting threats buried underground includes a housing, a shaped charge coupled to the housing at one end, and an explosive projectile disposed in the housing and spaced-apart from the shaped charge. The explosive projectile includes an open-ended pipe, a detonation line wrapped about the pipe and extending away therefrom and through the housing, an explosive material disposed about and in contact with the detonation line wrapped about the pipe. The explosive projectile also includes a first donut-shaped plate at one end of the pipe, a second donut-shaped plate at another end of the pipe, and a third donut-shaped plate coupled to and spaced-apart from the second donut-shaped plate. A flow path extends through the plates and the pipe.
