Munitions are encountered in a variety of underwater environments as unexploded ordnanceUXO or discarded military munitions DMM. The objective of this project was to validate an underwater suite of tools that can be used to render safe underwater UXO and DMM. Testing was conducted on inert Navy 5-inch38-caliber projectiles in a test tank demonstration 1 and in the ocean off a pier demonstration 2. The proprietary technology for underwater demilitarization of munitions utilized a suite of tools that accomplished the following1 cleaned a munition of external bioencrustations using a high-pressure waterjet cleaning tool, 2 positioned a cut and capture apparatus on the munition, 3 cut an access hole in the side of the munition using a high-pressure entrainment-style abrasive waterjet cutting head,4 removed the resulting plug, 5 washed out the internal contents of the munition using a high-pressure washout head, and 6 captured the effluent generated during operations without leakage to the environment.
