SpaceX begins assembling first Starship Super Heavy booster in South Texas
SpaceX has taken the first unequivocal step towards orbital Starship launches, kicking off assembly of the first Super Heavy booster (first stage) – a necessity for recoverable spaceship missions to Earth orbit and beyond.
Although SpaceX could technically get away with building much smaller booster prototypes to support Starship’s initial orbital test flights, perhaps going as far as simply modifying Starship’s proven tank design, rocketry really doesn’t lend itself to modularity. Be it out of confidence or necessity, SpaceX appears to be moving directly from Starship prototype development to full-scale Super Heavy booster production and testing.
The first conveniently labeled Super Heavy booster rings were spotted around September 22nd. In the six or so weeks since then, SpaceX’s Boca Chica, Texas factory has relentlessly churned out at least as many sections of stacked booster rings – now strewn about the ever-growing campus. No less than seven labeled Super Heavy ring sections have been spotted since the first, equating to fewer than 25 steel rings of the estimated 38-40 needed to complete each booster.
Relying on a tank design almost identical to hardware flight-proven on two separate Starship prototypes, SpaceX is able to use the exact same manufacturing infrastructure for the vast majority of Starship and Super Heavy. In fact, in a flip of the usual relationship, the next-generation rocket’s booster will most likely be far simpler than the upper stage – nominally the largest reusable spacecraft and upper stage ever attempted.
Without the need for a tiled heat shield, a conical nose section, aerodynamic control surfaces (beyond Falcon-style grid fins), or even (perhaps) internal header tanks, the only major challenge unique to Super Heavy is the development of an engine section capable of supporting and feeding as many as 28 Raptor engines. In other words, as long as the basics of Starship are successful and SpaceX is able to design a reliable 28-Raptor thrust structure and associated plumbing, Super Heavy may actually be a much easier problem to solve.
Theory aside, Starship and Super Heavy will unequivocally be the largest spacecraft, upper stage, and rocket booster ever built regardless of their success. While CEO Elon Musk recently stated that a Super Heavy booster could perform hop tests with just two Raptor engines, if necessary, the rocket is ultimately expected to have 20 high-thrust Raptors with minimal throttle capability and an inner ring of eight throttleable, gimballing engines for precision maneuvers.
With all 28 engines operating at full thrust, that particular Super Heavy design would produce an immense 6600 metric tons (14.5 million lbf) of thrust at liftoff – approximately twice the thrust of Saturn V and Soviet N-1 rockets and more than three times the thrust of SpaceX’s own Falcon Heavy. Measuring ~70m (~230 ft) tall, Super Heavy would weigh at least 3500 metric tons (7.7 million lb) fully loaded with liquid oxygen and methane propellant and – on its own – stand as tall or taller than Falcon 9, Falcon Heavy, and any other operational rocket on Earth.
Now effectively inaugurated with the first Super Heavy booster (“BN1,” according to SpaceX) hardware, the ~83m (~270 ft) tall high bay will likely be in a near-constant state of activity as teams work to stack and weld the massive steel rocket. Essential to support Starship’s first recoverable orbital launch attempts, it remains to be seen how exactly SpaceX will put the first completed Super Heavy through its paces and what the first booster-supported Starship launches will look like. Regardless, barring major surprises during assembly, Super Heavy booster #1 (BN1) could be more or less complete just a month or two from now.
Tesla has lost its Model Y Program Manager, he announced on LinkedIn, marking the second major departure from the company today.
Emmanuel Lamacchia has been in the role for 4 years and 7 months, responsible for the rollout of the all-electric crossover in several markets.
The Model Y became the best-selling vehicle in the world for two years under Lamacchia’s watch, making this a huge loss for the company. However, it seems the decision was made under Lamacchia’s own initiative.
He confirmed his decision on LinkedIn:
“After 8 incredible years, I’m moving on from Tesla.
What a journey it’s been… from leading NPI for Model 3 and Model Y variants to becoming the Vehicle Program Manager for Model Y, the best-selling car in the world!
Leading the All-New Model Y launch was the highlight: converting all 4 factories across 3 continents in just 2 weeks. Something that had never been done before in the auto industry.
To the teams who made this possible: you should be incredibly proud. This achievement belongs to you: the engineers, designers, buyers, and associates in Fremont, Shanghai, Berlin, and Austin who turned an impossible timeline into reality.
Grateful to the leaders who trusted me with programs that stretched my capabilities and to the cross-functional partners who showed me that great solutions come from collaboration, not hierarchy.
Tesla taught me how to move fast without breaking things and how to scale from prototypes to millions of units.
Excited for what’s next. More to share soon.”
It marks the second major program loss for Tesla today, as it also bid farewell to Cybertruck and Model 3 Program Manager Siddhant Awasthi, who said he left voluntarily in “one of the hardest decisions of his life.”
Lamacchia was at Tesla for just a shade under eight years, and previously worked for Rolls-Royce for roughly the same amount of time.
After the loss of both Lamacchia and Awasthi today, Tesla has lost a handful of key executives in 2025, including:
- David Imai, Director of Design
- David Lau, VP of Software Engineering
- Mark Westfall, Head of Mechanical Engineering
- Prashant Menon, Regional Director in India
- Vineet Mehta, Head of Battery Architecture
- Omead Afshar, VP/Head of Sales and Manufacturing in North America
- Milan Kovac, Head of Optimus Team
- Jenna Ferrua, Director of HR
- Troy Jones, VP of Sales, Service, and Delivery
- Pete Bannon, VP of Hardware Engineering
- Piero Landolfi, Director of Service

Tesla prepares to expand Giga Texas with new Optimus production plant
Drone operator Joe Tegtmeyer recognized Tesla construction crews performing ground leveling and clearing efforts at the plant earlier today.
Tesla is preparing to expand Gigafactory Texas once again with a brand new facility that will house the eventual manufacturing efforts for Optimus, its humanoid robot.
It is already building some units on a Pilot line at the Fremont Factory in Northern California, but Tesla is planning to build the vast majority of its Optimus project at Gigafactory Texas.
Tesla Optimus gets its latest job, and it’s not in the company’s factories
It will build one million units per year in Fremont, but CEO Elon Musk said the company would build 10 million units every year in Texas at a new building at Giga Texas.
Musk said:
“I think there could be tens of billions of Optimus robots out there. Um, now obviously it’s very important we pay close attention to safety here. Then a 10 million unit uh per year production line here the I don’t know where we’re going to put the 100 million unit production line. on Mars. Maybe on Mars, I don’t know.”
Evidently, Tesla is ready to begin thinking about the production efforts of Optimus beyond a theoretical standpoint and is starting to prepare for the construction of the manufacturing plant on Giga Texas property.
Drone operator Joe Tegtmeyer recognized Tesla construction crews performing ground leveling and clearing efforts at the plant earlier today:
Giga Texas News!
A brand-new, stand-alone factory is starting construction! This follows the Shareholders meeting & info that a 10-million-per-year @Tesla_Optimus production facility “on the Giga Texas campus” will be built & enter into production in 2027!
Here are some… pic.twitter.com/7ig5DohfOt

Production is still slated for 2027, at least at Gigafactory Texas. As previously mentioned, the company is building some units in Fremont for the time being, at least until subsequent versions of the Optimus project advance.
Tesla has done a great job of advancing Optimus forward, but it also has truly grand expectations for the project.
Musk said it could potentially be the biggest product in the history of the planet, as it will revolutionize the way humans perform tasks, probably eliminating monotonous tasks from everyday life.
Tesla revealed its first customer for the all-electric Semi truck after it launches next year. Who it truly is should not be a surprise.
The Semi is going to finally start deliveries to new companies outside of Tesla’s pilot program starting in 2026. The company has been building a dedicated production facility in Reno, Nevada, that has finally taken shape, but Tesla was evidently not finished with the Semi’s development.
Last week at the Annual Shareholder Meeting, Tesla said it had implemented some new designs into the Semi, helping with efficiency, updating its design, and making it a more suitable vehicle for hauling loads, as the changes also helped increase payload.
Tesla has obtained a lengthy list of companies that have committed to implementing the Semi in their own fleets, hoping to bring their logistics lineups up to date with electric powertrains and autonomous technologies.
While it is already operating a pilot program with PepsiCo. and Frito-Lay, Tesla will expand to other businesses, primarily using it internally after its launch.
Head of the Semi program at Tesla, Dan Priestley, said the company would be the first user of the vehicle after its launch next year. It has been using it to a certain extent, but the company has not been able to completely abandon gas haulers.
Instead, it will implement the Semi into its fleet for more sustainable vehicle logistics starting next year:
Tesla will be the first customer as we electrify our supply chain. This includes Texas operations.

Tesla has already received orders for the Semi from a variety of large companies, including Walmart, Sysco, Anheuser-Busch, UPS, DHL, J.B. Hunt, among others.
Many analysts see the Tesla Semi as a major contributor to future growth and increasing value within the company, especially from a Wall Street perspective. Some firms say the Semi is one of several near and medium-term contributors to the company increasing its market cap.
Cantor Fitzgerald is just one of those firms, as last week it explicitly listed the Semi as a catalyst.
Analyst Andres Sheppard said, “Overall, we remain bullish on TSLA over the medium to long term. We continue to see meaningful future upside from Energy Storage & Deployment, FSD, Robotaxis/Cybercab, Semis, and Optimus Bots.”
