more than triple the entire original contract. On 24 July 2009, US Special Operations Command (USSOCOM) announced that the ASDS was not going to be repaired citing "competing funding priorities." Follow-on programs After the Advanced SEAL Delivery System's cancellation, the Navy pursued the Joint Multi-Mission Submersible, although this follow-on program was abandoned in 2010 over cost concerns. These abandoned programs, and the currently operational SEAL Delivery Vehicle, are to be replaced by the Shallow Water Combat Submersible. Capabilities Two s were modified to deploy the ASDS, and the was built with the inherent capability to deploy the mini-sub. Planners originally intended the ASDS to be piloted by one submarine officer and one SEAL. This occurred during initial testing and operational evaluation. The sub was designed to carry 16 SEALs in addition to the two pilots. Smaller swimmer propulsion devices such as the STD (Swimmer Transport Device) may be carried internally (basically smaller scooters), and small Combat Rubber Raiding Craft (CRRC) or Inflatable Boat-Small (IBS) may be stored internally. However, such craft cannot carry gasoline engines due to safety issues on submarines and fuel issues in small spaces, and therefore have to be paddled or use small electric motors. Semi-rigid, rigid hull, and rigid-hulled inflatable craft such as the ZODIAC cannot be accommodated.
