An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge equipped with propulsion systems to maintain precise position and a large landing platform. SpaceX developed these vessels to recover the first stage (also called the booster) of its launch vehicles.
SpaceX routinely lands boosters of its Falcon 9 and Falcon Heavy rockets, either on a landing zone on the ground or on a drone ship. SpaceX landing zones are: SpaceX Landing Complex 1 (LC-1), USSF Cape Canaveral Space Force Station, Space Coast, Florida, USA SpaceX Landing Zone 1 (LZ-1) SpaceX Landing Zone 2 (LZ-2)
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.
ASDS may refer to: Autonomous spaceport drone ship, a mobile rocket landing platform; Advanced SEAL Delivery System, a former U.S. submarine
SpaceX attempted a landing on the drone ship on 10 January 2015. Many of the test objectives were achieved, including precision control of the first stage's descent to land on the platform at a specific point in the south Atlantic Ocean and a large amount of test data was obtained from the first use of grid fin control surfaces used for more ...
