A Shortfall of Gravitas

A Shortfall of Gravitas droneship pre-conversion - Bollinger Shipyard

A Shortfall of Gravitas (ASOG) is a future SpaceX autonomous spaceport droneship (ASDS). ASOG is currently under construction at Port Fourchon, Louisiana. The droneship is expected the enter service in mid-to-late 2021, operating out of Port Canaveral, Florida. The droneship is based upon barge Marmac 302.

A Shortfall of Gravitas has been teased by SpaceX boss Elon Musk frequently since it was first announced in 2018. A further update by Elon suggested that the droneship would enter service in 2019 but no further updates were provided and this did not happen.  

Musk once again mentioned the droneship in October 2020, fueling rumours that the project had been restarted. A brand new Octagrabber robot was spotted in March 2021 at SpaceX Cidco Road facility. SpaceXFleet.com was able to first locate Marmac 302’s position at Bollinger Shipyard in May 2021 and photographers were able to confirm that the droneship was under construction.

The droneship design is expected to be similar to Just Read the Instructions, which received its own upgrade in 2020
