Abstract: A liquid disruptor device and a method of manufacturing the same are introduced. The liquid disruptor device comprises a front casing, a liquid seal film, a rear casing, a plane wave generator and a counter-impact cover. The plane wave generator generates a plane blast wave which compresses a liquid contained in the front casing and a liner to not only focus blast energy of the liquid but also allow the liquid to form a liquid knife current for destroying explosives. Hence, the liquid disruptor device displays higher efficiency per unit weight of explosives when detonation thereof occurs at multiple points. Further, a liquid disruptor device module inclusive of at least two liquid disruptor devices combined to assume a geometric shape is introduced.
