New photos which is shared by SpaceX show that the company has nearly finished installing in total of 39 upgraded Raptor Engines on a new Starship for its Super Heavy booster.
These prototypes – also known as Ship 24 and Booster 7 – which could be tasked with supporting Starship’s first orbital launch attempt after some time later in this year if both make it through upcoming test campaigns without any major issues. Whether that’s a probable outcome or may still uncertain but recent progress suggests that it won’t take any more for those aspects of both prototypes to shift into more clear focus.

About SpaceX six weeks Booster 7
SpaceX used the six weeks Booster 7 which spent back in the factory assembly bay to finish the installing of aerocovers surfaces which is known as chines or strakes and car-sized grid fins and Starlink internet dishes and – the most importantly exclusive 33 upgraded Raptor V2 engines.
Combine all booster 7 could produce all to 7600 metric tons (~16.8M lbf) of thrust during or before liftoff. Specifically, SpaceX also finished installing most of the Booster 7’s Raptor heat shield in the same time period, which is completing in six weeks work that took Booster 4 closer to half an year. With its heat shield and all 33 Raptors which are mostly in place, the Booster 7 should be ready to kick off static fire testing as early as it’s installed on Starbase’s orbital launch mount.”
Building, qualifying, shipping, and installing raptor and 2 engines on Super Heavy B7 which was already an impressive achievement and produced the main (potentially) powerful rocket booster after ever assembled.
On July 2nd and a pair of pictures which is published by SpaceX showed off Booster 7’s nearly-finished engine section and similarly revealed that the company which have finished installing all of six Starship S24’s Raptor engines and even every part of the ship’s aft heat protection.
Difference between Ship24 and Ship20
Differences are already can seen between Ship 24 and Ship 20 and the only another Starship which prototype to have six Raptors which are installed. The most specific change is in the addition of a metal framework that covers the whole breadth of the ship’s aft and almost likely destined to support the flat sections of insulation and heat protection that will half seal off sensitive engine, plumbing, pressure vessels, and avionics parts located inside the Starship’s aft. That extra shielding shall help limit the extreme conditions that the hardware will be subjected to while ths ground testing and, perhaps, in the flight.
Testing of Super Heavy Booster7
Super Heavy Booster 7 have already completed very significant amount of testing which includes four cryogenic proofs (cryoproofs) and one Raptor thrust for simulation test. Since during its third return to the pad, SpaceX have to done several more ambiguous tests and none of which appeared to involve cryogenic propellant loading.
It’s possible that those tests which are done yet are focused more on Booster 7’s pressurization system, while filling its tanks with the hot oxygen and methane gases will eventually use to pressurize the tanks
It’s likely that SpaceX which wants to put Booster 7 through at least one successful infused dress rehearsal – using real liquid methane and real oxygen propellant – before attempting to the static fire any of its 33 Raptors.
Salient Features of Super Heavy booster7
Booster 7’s aft heat protection system also isn’t entirely completed so technicians will need to finish all installing of several panels before any static fire testing.
Alongside with B7, Starship S24 has completed a great amount of cryoproof and Raptor thrust of simulation testing which it survived without any repearable issues.
The ship was then returned to an assembly bay in the month of June on 9th where were workers have been installing thermal shield tiles, finalizing the ship’s engine section, and completing all of dozens of another less visible closeout tasks.
SpaceX also finished the modifying features one of its two suborbital test and launch mounts for Starship static fire testing, leaving the another mount of semi-permanently modified for cryoproof and for thrust simulation testing of the future prototypes.
