Booster 4 was the first vehicle intended to fly on Starship's Flight Test 1. It was the first Super Heavy to be stacked with Starship, [77] and conducted multiple cryogenic tests before being retired in favor of Booster 7 and Ship 24. [78] Booster 7 being tested on the orbital launch pad at Starbase, Boca Chica, Texas in February 2023.
The Super Heavy booster is reusable, and is recovered via large arms on the tower capable of catching the descending vehicle. [8] As of January 2025, 0 boosters have been refurbished and subsequently flown at least a second time, though 2 boosters, Booster 12 and Booster 14, has been recovered after flight, with Booster 12 having damage to one ...
^F Falcon Heavy has launched 11 times since 2018, but first three times did not qualify as a "super heavy" because recovery of the center core was attempted. ^G Apollo 6 was a "partial failure": It reached orbit, but had problems with the second and third stages. ^I Estimate by third party. ^J Engines reusable, booster reuse unproven.

The pieces include the massive Super Heavy booster topped with the SN 20, as in Serial Number 20, version of the Starship prototype. Together, the combined rocket stands at 394 feet. In comparison ...
When stacked and fully fueled, Starship has a mass of approximately 5,000 t (11,000,000 lb), [c] a diameter of 9 m (30 ft) [17] and a height of 121.3 m (398 ft). [6] The rocket has been designed with the goal of being fully reusable to reduce launch costs; [18] it consists of the Super Heavy booster and the Starship upper stage [19] which are powered by Raptor and Raptor Vacuum engines.

The ITS booster was to be a 12 m-diameter (39 ft), 77.5 m-high (254 ft), reusable first stage powered by 42 engines, each producing 3,024 kilonewtons (680,000 lbf) of thrust. Total booster thrust would have been 128 MN (29,000,000 lbf) at liftoff, increasing to 138 MN (31,000,000 lbf) in a vacuum, [ 45 ] several times the 36 MN (8,000,000 lbf ...
