Booster 2.1 is a test tank that was spotted in October 2021. On October 29 it was lifted onto what Chris Bergin believed is a Booster Thrust Simulator.
The test tank was moved back to the production facility on December 6, where it found a new home near SN15 and Ship 16. B2.1 was observed being lifted off the stand on a NASASpaceFlight livestream, around January 25, 2022.
