SpaceX tests Starship and Frankenstein ‘test tank’ simultaneously
After another few weeks of downtime, SpaceX has simultaneously tested the first orbital-class Starship prototype and a Frankenstein-esque ‘test tank’ at its South Texas facilities. While nothing that occurred was all that visually spectacular, the afternoon of testing was still noteworthy for a couple of reasons.
First up, following a successful six-engine Raptor static fire – the first in Starbase history – on November 12th, all signs pointed to Starship S20 attempting another static fire (its fourth) on December 1st. In the almost three weeks of inactivity between those planned tests, SpaceX likely performed extensive inspections of the pathfinder prototype and its Raptor engines. Technicians also repaired the minor heat shield damage and tile loss that testing incurred and patched a few other ‘holes’, effectively leaving Ship 20 with the first fully finished heat shield by the end of November.
Earlier this week, one of the few remaining Boca Chica Village residents received a safety notice from SpaceX indicating that a static fire test was scheduled on Wednesday, December 1st – followed soon after by a notice to mariners (NOTAM) warning boaters to keep to a safe distance. Two hours into the 10am to 6pm CST test window, Starship S20 was already venting and starting to get frosty, confirming that propellant loading had begun. A little over an hour later, it was clear that SpaceX had aborted the first static fire attempt of the day. For the next three hours, Ship 20 exhibited some unusual behavior including new vents, an apparent header tank pressurization or fill test, and still more odd venting in new places.
In the middle of Starship’s weird nose-related testing, SpaceX began simultaneously loading a new ‘test tank’ known as B2.1 with liquid nitrogen (LN2) – marking the first truly simultaneous test of multiple Starship test articles. As Ship 20 seemingly detanked for the second time that day, the B2.1 tank was fully loaded with LN2 and apparently pressure-tested not long after. A few hours later, the test tank was also detanked and the road to the pad was reopened, marking the end of the day’s testing.
Normally, nothing is particularly unusual or noteworthy about test tank testing. Since January 2020, SpaceX has routinely built and tested tanks that are effectively just shorter versions of actual tanks and hardware, using them to qualify changes to Starship’s design, materials, operations, and more before applying those changes to full-size prototypes. B2.1 is the tenth dedicated test tank to reach the launch pad in a little under two years.
Normally, the ‘B2.1’ name SpaceX has given the tank would imply that it’s a newer booster test tank (using Bx instead of BNx) following in the footsteps of BN2.1, which passed cryogenic and load testing this summer. Instead, though, B2.1 is a bit of a nightmarish amalgamation of seemingly random Starship and Super Heavy parts. Its forward dome is an old, unused booster section complete with the hexagonal structure grid fins would have been brace against. Its aft section is a booster thrust structure. Up to that point, it’s effectively just a copy of BN2.1.
However, SpaceX inexplicably installed a Starship thrust dome inside B2.1’s booster thrust structure, creating a test tank with no obvious relevance to any conceivable Starship or Super Heavy design or prototype. Further, SpaceX rolled B2.1 to the launch site for testing only after installing it on an unused device that’s believed to be the aft half of a dedicated booster structural test stand. In theory, a sort of ‘cap’ would be fitted on top of a booster or test tank installed in the stand’s base and strong cables would connect the two, allowing SpaceX to subject prototypes to compressive stress – like, perhaps, the forces a booster might experience while carrying a fully-fueled 1300-ton Starship to space. The upper half of that test structure has yet to be moved to the launch site.
Altogether, the weird half-complete test stand and bizarre fusion of ship and booster parts make B2.1’s purpose and initial testing a complete mystery. It’s unclear what value it provides that makes it more of a priority than, say, finally starting to test the first flightworthy Super Heavy booster (B4). Ultimately, the most interesting thing about B2.1’s test debut is the fact that it appears to mark the first use of Starbase’s brand new orbital tank farm, which is approaching completion.
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.”
