Test Tank 1 (TT1) was a subscale test tank consisting of two forward bulkheads connected by a small barrel section. TT1 was used to test new materials and construction methods. On January 10, 2020, TT1 was tested to failure as part of an ambient temperature test, reaching a pressure of 7.1 bar.

Test Tank 2 (TT2) was another subscale test tank similar to TT1. On January 27, 2020, TT2 underwent an ambient temperature pressure test where it reached a pressure of 7.5 bar before a leak occurred. Two days later, it underwent a cryogenic proof test to destruction, bursting at 8.5 bar.

GSE 4.1 was first spotted in August 2021 and was the first ground support equipment (GSE) test tank built, made from parts of GSE 4. It underwent a cryogenic proof test on August 2023 before it was rolled to Sanchez site. It was rolled back to the launch site in November 2021, where it underwent an apparent cryogenic proof test to failure on January 18, 2022, where it burst at an unknown pressure.

EDOME was a test tank created to test flatter domes, possibly used on future Starship prototypes. It was moved to the launch site in July 2022, and then back to the production site the next month, after undergoing no tests. It was later moved from the production site to the Massey's test site in late September 2022, where it was damaged during a cryogenic pressure test to failure. After repairs, it was tested to destruction in late October 2022.

EDOME 2 was a test tank which is likely designed to continue testing a flatter dome design. As of October 4, 2023, its official designation is unknown. It was tested once, before being scrapped for unknown reasons.
