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.

Since this diagram was published, SpaceX has also tested BN2.1, GSE-4, and now B2.1.

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 officially begun hiring for its new $200 million Megafactory in Brookshire, Texas, a manufacturing hub expected to employ 1,500 people by 2028. The facility, which will build Tesla’s grid-scale Megapack batteries, is part of the company’s growing energy storage footprint. 

Tesla’s hiring efforts for the Texas Megafactory are hinted at by the job openings currently active on the company’s Careers website.

Tesla’s Texas Megafactory

Tesla’s Brookshire site is expected to produce 10,000 Megapacks annually, equal to 40 gigawatt hours of energy storage, similar to the Lathrop Megafactory in California. Tesla’s Careers website currently lists over 30 job openings for the site, from engineers, welders, and project managers. Each of the openings is listed for Brookshire, Texas.

The company has leased two buildings in Empire West Business Park, with over $194 million in combined property and equipment investment. Tesla’s agreement with Waller County includes a 60% property tax abatement, contingent on meeting employment benchmarks: 375 jobs by 2026, 750 by 2027, and 1,500 by 2028, as noted in a report from the Houston Business Journal. Tesla is required to employ at least 1,500 workers in the facility through the rest of the 10-year abatement period. 

Tesla’s clean energy boom

City officials have stated that Tesla’s arrival marks a turning point for the Texas city, as it highlights a shift from logistics to advanced clean energy manufacturing. Ramiro Bautista from Brookshire’s economic development office, highlighted this in a comment to the Journal

Tesla’s Shanghai Gigafactory has reached a major production milestone, with its five millionth battery pack rolling off the line this week. 

The achievement highlights Giga Shanghai’s role as the automaker’s highest volume manufacturing complex and primary vehicle export hub.

Giga Shanghai’s new milestone

Tesla announced the milestone on X and Weibo, sharing images from the facility where the five millionth pack was completed. Images showed the Giga Shanghai team posing for a commemorative photo with the facility’s five millionth battery pack. Several of the company’s executives congratulated the Tesla China team for its recent milestone, including SVP Tom Zhu, who wrote “Power up, team!” in a post on X.

While Tesla designs and assembles its battery packs in China, the cells themselves are supplied by local partner CATL and South Korea’s LG Energy Solution, as noted in a CNEV Post report. Tesla China has stated that its pack safety standards exceed industry norms several times over, with longevity engineered to outlast vehicle lifespans.

Giga Shanghai’s growing role

Construction of Giga Shanghai began in early 2019, becoming China’s first wholly foreign-owned auto manufacturing facility. Giga Shanghai’s first phase was completed within the year, producing Model 3 sedans by the end of 2019. It now produces both Model 3 sedans and Model Y SUVs for domestic and export markets, with an annual capacity approaching one million vehicles.

Despite the record-setting battery milestone, Tesla China’s recent domestic results left a lot to be desired. As per the China Passenger Car Association, Tesla’s retail sales in October dropped 36% year over year to 26,006 units, the lowest since late 2022. Analysts attributed the decline to Giga Shanghai’s focus on exports last month, as well as the ramp of compelling rivals like the Xiaomi YU7.

Tesla confirms upcoming launch of FSD Supervised in South Korea

The announcement came through a post from Tesla Korea’s official account on X.

Tesla has confirmed that it will be releasing its Full Self-Driving (FSD) Supervised system in South Korea. The announcement came through a post from Tesla Korea’s official account on X, which featured a video showing the system navigating local roads in a Tesla Model S sedan.

FSD Supervised in South Korea

The teaser video posted by Tesla Korea showed a vehicle performing lane changes, navigating intersections, and even parking without driver input, all while the driver kept their hands off the steering wheel. The footage was filmed on domestic roads, suggesting that Tesla Korea has been initiating FSD test drives in the country for some time.

Tesla’s FSD software currently exists in two versions: supervised and unsupervised. The supervised version still requires driver attention, while the unsupervised variant, which is being used in the company’s Robotaxi service, allows full autonomy. Tesla has confirmed plans to expand supervised FSD to Europe, and China, as well as markets like Japan, sometime next year.

South Korea’s FSD likely for U.S.-made cars to start

In South Korea, Tesla’s popularity has surged despite FSD not yet being available in the country. This is largely due to the new Model Y, which was launched in April. Thanks to the vehicle’s reasonable price and features, the new Model Y has driven domestic sales up 92.8% year-over-year, securing Tesla’s place among the country’s top imported carmakers.

With FSD, Teslas become significantly more compelling vehicles. Analysts warn, however, that legal and regulatory hurdles could complicate FSD’s local introduction. Over 80% of Teslas sold in South Korea are manufactured in China, and those vehicles must comply with domestic safety standards, as noted in a Chosun report.

Industry experts suggest the first wave of FSD-enabled vehicles will likely be U.S.-made, as models built under the Korea-U.S. Free Trade Agreement automatically meet South Korean safety requirements.

“Since the supervised FSD is a technology that assists driving, its introduction in South Korea is technically feasible. However, potential conflicts with domestic road laws and safety standards are a concern,” one industry insider told local media. “US-made vehicles are not subject to South Korean safety standards due to the Korea-US FTA, making FSD implementation relatively easier, whereas the situation differs for Chinese-made vehicles.
