The Army plans to remove unexploded munitions from the ocean floor off the coast of Waianae over the next three weeks. 

Normally the military has divers take potentially dangerous munitions out of the ocean, but this time it is testing the use of a remotely controlled robot to do the job. 

The target is some 2,000 unexploded weapons sitting off Oahu’s Waianae coast, ranging from small arms munitions to large caliber projectiles and naval gun ammunition. The weapons are believed to be from the World War II era and were likely dumped in the ocean after the war. 

The military disposed of old weapons in the sea up to 1970 because it believed doing so was safer than burying them in the ground or burning them.
