The Acastia or "A" class of destroyers were completed in 1930-1931. They incorporated novel boiler technology and minesweeping gear but were very light on antisubmarine equipment, having no sonar nor depth charge throwers as completed. The design emphasis seems to have been on torpedo attack capability and improved habitability. The minesweeping gear and after torpedo tubes were removed by the time the Pacific War broke out in favor of much increased antisubmarine capability.
