SpaceX’s first Starship booster a step closer as custom parts arrive
While SpaceX remains focused on Starship flight testing as the dust settles from SN8’s launch debut, the company continues to make slow but steady progress building the first Super Heavy booster prototype.
For the most part, SpaceX has learned from trial and error and developed a decent stainless steel rocket manufacturing process by building a dozen Starship prototypes over the last ~12 months, ranging from a lone nosecone tip to stout test tanks and Starship SN8, which launched to 12.5 km (~7.8 mi) earlier this month. Practically identical below the nose, Super Heavy directly benefits from that maturity and is more or less an extended Starship tank section with more engines and bigger legs.
In many ways, Super Heavy can be much simpler than Starship, as a suborbital booster has no need for header tanks, flaps, or a nosecone, and can be much stronger and heavier in all aspects. However, carrying three or more times as propellant as Starship (and carrying Starship itself), Super Heavy also needs to be stronger. All those changes – requiring new design work and new fabrication – take time. In a great sign that most of that work is complete, some of that custom hardware needed to strengthen and power Super Heavy has begun to arrive over the last several weeks.
SpaceX began stacking the first Super Heavy booster (BN1) on November 8th and appears to have more or less paused integration operations after joining eight rings. Production continued apace, however, and no less than five ring sections destined for Super Heavy appeared over the next several weeks. Why assembly slowed down is unclear but it’s reasonable to assume that SpaceX was trying to keep its focus primarily on Starship SN8’s launch debut and the preparation of several other full-scale ships, where early work on Super Heavy could ultimately be for naught if Starship flight tests uncover major design flaws.
Regardless of the reason, BN1 remains eight rings (14.5m/48ft) tall as of December 14th, representing one-fifth of Super Heavy’s full 70-meter (~230 ft) height.
On December 17th, one of the parts unique to Super Heavy unexpectedly appeared in SpaceX’s South Texas shipyard, labeled “B1 FWD PIPE DOME”. The dome was quickly sleeved with a stack of three steel rings with labels confirming that the assembly was Super Heavy BN1’s common tank dome – “common” because it’s shared by both booster propellant tanks. The new dome is unique to all previous Starship domes, featuring a smaller, more reinforced cutout – likely because Super Heavy doesn’t need header tanks.
It also appears to borrow from Starship’s forward dome design, using the same rougher steel normally used to cap off Starship methane tanks.
Unlike Starship common domes, which place a spherical methane header tank at the bottom, Super Heavy’s common dome will have a transfer tube welded directly to its nozzle-like opening. As it turns out, what could be the first Super Heavy methane transfer tube was delivered to Boca Chica late last month.
Unlike Starship transfer tubes, the new plumbing appeared to have a much wider diameter and was delivered in four sections, meshing well with the fact that Super Heavy tanks are roughly twice as tall as Starship’s. Able to support as many as 28 Raptors compared to Starship’s 6, Super Heavy transfer tubes will also need to pump more than five times as much methane per second at full thrust, which could explain the larger diameter.
Finally and perhaps most significantly, aerial photos from RGV Photography appeared to capture the first glimpse of what might be the hardest custom part required by Super Heavy – a thrust structure designed to support up to 28 Raptor engines. On December 10th, casually sitting between Starship Mk1’s remains (on the white concrete mount) and a tent, a flat ring with clear eightfold symmetry and a donut-like cutout large enough to fit a Starship thrust puck with room to spare was easily visible.
The hexagonal symmetry was the main giveaway, matching comments from CEO Elon Musk that Super Heavy’s thrust structure will feature a central ring of eight engines surrounded by an outer ring of up to 20 more Raptors. Assuming the first Super Heavy booster only flies with a few Raptor engines, that sole eight-engine ‘puck’ may be all that SpaceX needs to complete BN1.

It appears that there are several big changes to this next-generation version of Optimus, some of which have been discussed by Musk and Tesla in the past.
The first is purely cosmetic, but the gold color that Optimus is wearing in this is a new and fresh look that we have not seen before.
Perhaps the most interesting change that is evident here is the hands, which are much more detailed than past versions of Optimus:
However, we’re not too sure that these are what will be released with the next-gen Optimus, because they don’t appear to be functional, and they are more reminiscent of mannequin hands than anything.
The hands on Optimus have been a significant part of the program, as they are among the most crucial pieces of equipment on a robot. It needs to be able to perform both delicate and more imposing tasks. Tesla has aimed for Optimus to be able to thread needles or play the piano.
It was one of the most discussed improvements the company mentioned in past comments regarding how it planned to improve from Gen 2 to this next version.
Musk mentioned regarding Optimus:
“Next-generation Optimus hand, which we have in prototype form, has actuators that have moved to the forearm, just like humans, and they operate the fingers through cables, just like human hands.”
Within Optimus lies a significant opportunity for Tesla to gain considerable strength in terms of market share and valuation.
If Tesla can efficiently develop and deploy the humanoid robot over the next several years, the company stands to gain, as companies will utilize it for tasks that require tedious labor.
Musk recently said Optimus will be a major contributor to Tesla’s valuation moving forward. He believes it will make up roughly 80 percent of the company’s value.

Tesla CEO Elon Musk to provide more details for Master Plan Part IV
Musk stated that he would be adding specifics to the plan in a later update.
Tesla CEO Elon Musk will be adding more specifics to the recently-released Master Plan Part IV. Musk shared the update on social media platform X amidst conversations about the general nature of the Master Plan Part IV.
In a conversation on X, Musk responded to a post from Tesla retail shareholder and bull Dave Lee, who observed that the currently released Master Plan Part IV could really just be the introduction to the real plan due to its absence of specifics.
Elon Musk responded, stating that he would be adding specifics to the plan in a later update. “Fair enough. Will add more specifics,” Musk wrote in his post.
Tesla has been following Elon Musk’s Master Plans for decades. The first Master Plan, released in 2006, outlined the company’s path from the original Tesla Roadster to the Model 3, as well as the first steps for Tesla Energy. Master Plan Part Deux, released in 2016, covered the ramp of Tesla Energy, the expansion of Tesla’s vehicle lineup, and the rollout of a Robotaxi service.
Master Plan Part 3 was more ambitious as it was generally an in-depth proposal for achieving a global sustainable entry economy by transitioning to electricity-powered vehicles, homes, and industry, which will, in turn, be powered by renewable energy sources like solar and wind. Master Plan Part 3 also included a five-step plan to accomplish this, allowing the world to transition to a fully electrified future.
Master Plan Part IV, which was released a few days ago, focused on automation and artificial intelligence to achieve sustainable abundance. But while the first two Master Plans were very clear and specific and Master Plan Part 3 was very in-depth, Master Plan Part IV was quite general and vague in comparison. It was easy to tell that Optimus would play a big role in the pursuit of sustainable abundance, but apart from that, there were no specifics as to how Tesla intended to achieve its goals.
Fortunately, these specifics would be discussed by Musk in a later update to the plan.

Tesla just had its best wholesale month this year in China
Tesla China’s wholesale figures include both vehicles that are sold domestically and exported abroad.
Tesla China just had its best wholesale month this 2025 so far. In August, the electric vehicle maker sold 83,192 vehicles wholesale, a 22.55% increase compared to July 2025’s 67,886 units.
Tesla China’s wholesale figures are still down year-over-year, but the company’s momentum seems notable, especially with the arrival of the Model Y L.
August 2025 figures
As noted in a CNEV Post report, August 2025’s 83,192 wholesale figures are 4.04% less than the 86,697 units that were sold in the same period last year. It is, however, a 22.55% improvement from the previous month. From January to August, Tesla China sold 515,552 units wholesale, a 12.24% year-over-year decrease.
It should be noted that Tesla China’s wholesale figures include both vehicles that are sold domestically and exported abroad. With this in mind, August’s results bode well for Tesla China, as it suggests that Gigafactory Shanghai is now hitting its pace with both its domestic deliveries and its exports. Giga Shanghai serves as Tesla’s primary vehicle export hub.
Model Y L factor
Tesla had a challenging first quarter this year, thanks in part to the changeover to the Model Y across the Fremont factory, Giga Texas, Giga Shanghai, and Giga Berlin-Brandenburg. This changeover resulted in low sales in the first quarter. Political controversies surrounding Elon Musk and violence against Tesla stores and vehicles in the first and second quarters in the United States and Europe did not help much either.
This Q3, however, Tesla seems to be hitting its stride, especially in China. The launch of the new Model Y L has allowed Tesla to compete in the six-seat, large SUV segment, a market that was previously closed to the standard Model Y. Reports have suggested that Tesla China has been seeing a lot of demand for the Model Y L, which should help the company achieve higher sales this quarter and the remaining months of the year.
