The decommissioned cargo ship ex-USS Durham was attacked and sunk on August 30 as part of the Rim of the Pacific (RIMPAC) multinational exercise.
The 2020 exercise, in the sea around Hawaii, involved 10 nations, 22 surface ships, one submarine, and approximately 5,300 personnel, according to the US Pacific Fleet.
Former Navy vessels used in sinking exercises “are prepared in strict compliance with regulations prescribed and enforced by the Environmental Protection Agency,” the Navy said.
Surveys are conducted to ensure people and marine mammals are not in the area, they said.
