A 12-year Navy program to develop six minisubs for commando missions has been canceled after a $446m investment, leaving the one and only sub at Pearl Harbor with an uncertain future, the Honolulu Advertiser reported. With an original estimate that a single sub would cost about $80m, the price tag for the one vessel that was delivered is $366m above projections. The 65-foot Advanced SEAL Delivery System, or ASDS, was heralded as a "transformational leap ahead" and was intended to deliver commandos dry and rested to a point of departure — rather than in the current underwater vehicles that are open to bone-chilling cold water and require the use of scuba gear.
