The U.S. Navy's latest two-man submarines, launched in a twin launching at New London. They're built for extensive ocean research at depth of up to two thousand feet. The Navy predicts squadrons of them in the future. They're launched by crane, which picks them up and plops them in! Panning shot of the dock with two small 2-man submarines sitting on it.
