Abstract
An expendable underwater vehicle for use in training naval forces in anti-submarine warfare in ocean waters is between about three to five feet in length and about five inches in diameter, and it includes various improvements which make successful operation in the ocean waters possible. The improvements include an in-water variable speed feature, a variable tonal levels feature, an autonomous evasion feature, and a high-power integrated pinger feature. One or more of these features can be combined to provide an extremely effective and versatile expendable underwater training vehicle.
