30 kilotons – A Mark 90 Betty nuclear bomb was detonated at a depth of 610 m (2,000 ft) about 800 km (500 miles) southwest of San Diego (California) during Operation Wigwam. The test on May 14, 1955, was to determine the effects of deep nuclear blasts on submarines. An underwater explosion is also known as an UNDEX.
