The metal rings for the Super Heavy booster appear to be under construction. The ring segments for the Super Heavy Booster match up with the ring segments on the lower portion of the upper stage Starship. There are now about 11 extra steel ring segments at the SpaceX Florida facility. This would be about 14 to 18 meters of the Super-Heavy Booster.
Musk has said Starship could be ready for its first orbital flight tests as early as December 2019 and the SpaceX’s first Super Heavy prototype could be fully assembled by the end of 2019 or very early in 2020.
