Last updated: November 12, 2017 at 3:17 am

610 m (2,000 ft) – A Mark 90 nuclear bomb was detonated about 500 miles southwest of San Diego (California) during Operation Wigwam on May 14, 1955. The test was to determine the effects of deep nuclear blasts on submarines. The cold war nuclear depth charge, also known as Betty, carried a Mark 7 nuclear warhead with a yield of 5-10 kilotons.
