ASDS was conceived to address the need for stealthy long-range insertion of special operations forces on covert or clandestine missions. It was designed to replace the wet SEAL Delivery Vehicle (SDV), which exposed combat swimmers to long, cold waits during transit that impeded combat readiness on arrival, limited operational range, and hindered underwater navigational capability.
The contract was fulfilled when the full operational capability was met in 1999. In all, 20 Mk V SOC units were delivered to USSOCOM at a unit cost of $3.7 million. The Mark V SOC deployment was less smooth. Problems included instances of the windshield and entire pilothouse assembly collapsing upon wave impact.

The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the Earth's atmosphere. [1] It helps maintain pressure when stratocruising and protects the aircraft from bursting due to the higher internal pressure.
Engineering and economic analysis in 1996 suggested that a replacement bridge would cost a few hundred million dollars more than a retrofit of the existing eastern span, would have a far longer expected useful life (perhaps 75 to 100 years rather than 30), and would require far less maintenance.
