SuperHeavy B9

Booster 9 launched with Ship 25 on the Second Integrated Flight Test on Nov 18, 2023. During the first stage firing, all 33 engines were fired full duration. Starship and Super Heavy passed through hot staging, but the booster was lost shortly after initiating its flip maneuver and boostback burn. The Starship second stage had its flight termination system activated around the time of engine cutoff, after having continued powered flight until more than eight minutes after launch and reaching over 80 percent of orbital speed.

This Booster model has been updated with a more accurate version of the upper dome as well as the gridfin actuators. B9 upperdome only had two CH4 pipes. Photos from Richard Armenta.

SuperHeavy B7

Ship 24 and Super Heavy 7 was launched on its First test flight on Thursday April 20, 2023. The Booster lost 8 of 33 engines resulting in the loss of control and spinning erratically before booster separation. A command was sent to destroy the entire vehicle.

B7 consists of 36 rings and new upgraded grid fins.

Engine section consists of 20 outer Raptors and 13 inner Raptors

New COPVs arrangement as 2 vertical columns, and 2 thinner chine columns on the umbilical area.

SuperHeavy B4

The SuperHeavy booster 4 is the first booster planned to make an orbital launch together with Starship SN20. On August 6, 2021 it was fully stacked with SN20 on top of the Orbital Launch Pad (OLP). SN20 was further destacked on the same day and on August 10, B4 was removed from the OLP, too.

As of Nov 2021, Starship SN-20 / Ship 20 was slated to be tested for the First Orbital Test flight, launching on top of Super Heavy booster 4. The test will be no earlier than March 2022. The test involves separation of the booster and splashing down in the Gulf of Mexico, while Ship 20 will accelerate to orbital velocity and will re-enter over the Pacific Ocean splashing down near Hawaii. But on Feb 10, 2022, the SN-20 and B4 were stacked for Elon Musk’s presentation at Starbase. Days later, SN20 was unstacked from B4 again. It is unsure which Ship will fly to orbit first.

Vehicle details:

B4 consists of 36 rings with grid fins. It has 20 fixed Raptor engines on the outer engine ring and 9 gimbaled Raptors on the thrust puck dome.

There are 4 sets of COPVs in pairs at the bottom portion of the booster and two power units, too.

SuperHeavy BN-3

The SuperHeavy booster BN-3 was rolled out on July 1, 2021 from the High Bay and was placed on Suborbital pad A modified mount for a series of ground testing objectives.

The booster consists of 36 rings with no grid fins.

The engine section has two parts: the thrust dome that will hold 9 Raptors, and an outer ring that will hold 20 fixed Raptors. The BN-3 booster has Raptor engines: sn62, sn57 and sn59.

The BN-3 test will pave the way for booster 4 which will host Starship 20 for a full stack orbital ride later this year.
