USS Thach was fired upon from air, sea and underwater last Thursday in the exercise known as SINKEX.
The retired ship was hit with over 5,000 pounds of high explosives as ships, submarines and aircraft from the US, Canada, Australia and South Korea took part.
The 31-year-old frigate, which was retired in 2013 was towed to an area 55 miles north off the coast of the tiny mid-Pacific island of Kaui before testing commenced.
Video taken from a helicopter shows Australian frigate HMAS Ballarat and American cruiser USS Princeton firing harpoon missiles at the vessel.
US aircraft also joined in with US Navy F/A-18 Hornets dropping a 2,000-pound Mk. 84 bomb and a US Air Force B-52 bomber also bombarding it a GBU-12 Paveway laser guided 500-pound bomb.
A submarine from the US also joined in striking the target with Mk.48 torpedoes from below the waves.
The USS Thach finally sank at 7.25pm on July 14, in waters around 15,000 feet deep.
