SpaceX’s first completed BFR spaceship section spotted in huge Port of L.A. tent

Published

on

Described by CEO Elon Musk as “the first [completed] cylinder section” of SpaceX’s first BFR spaceship prototype, Teslarati’s West Coast photographer spotted the massive 9 meter (~30 foot) diameter carbon composite structure – looking exactly as it appeared in photos SpaceX provided during the Sept. 17 reveal – inside the company’s dedicated BFR fabrication tent.

Located at the Port of Los Angeles, SpaceX erected a huge, temporary tent at a leased berth in December 2017, choosing to begin fabrication of the first BFR composite structures in a more impromptu manner rather than waiting for the completion of lengthy regulatory processes and many more months of construction of a dedicated Mars rocket factory, also to be sited at Port of LA. Both the factory and temporary facility were located in a port (rather than at SpaceX’s already-established Hawthorne factory) due to the simple impracticality of transporting 9m-diameter parts through downtown Los Angeles, estimated to cost a minimum of several million dollars one way from a spattering of past transport projects.

Nine months after the structure was little more than a metal skeleton, SpaceX’s tented facility is now a mature in situ manufacturing wing of the company, evidenced by the fact that SpaceX has already completed its first full-scale composite section (both a section of the spaceship’s fuselage and one of its propellant tanks) and is pushing ahead into full builds of composite tank domes and the spaceship prototype’s Raptor engine section. It may not be practical as a long-term solution, and that certainly is not the plan, but SpaceX seems to be having very little difficulty growing into the eccentric aerospace composites manufacturing hub.

 

Judging from photos of the fresh composite tank section peeking its head out of the tent flap, the question of “How does SpaceX move this outside?” becomes rather unavoidable, and it seems that the plan is to fabricate and assemble the vast majority of the prototype spaceship’s monolithic composite structures before quite literally cutting out a section or partially disassembling the tent.

Thankfully, the dedicated BFR factory SpaceX is now in the process of building happens to be just a few miles away from the tent that manufacturing work is currently housed in, and that should make for relatively easy barge transport to said factory once its first phase of construction is complete (as early as Q2-Q4 2019). As of September 1st, the future location of that factory is currently going through gradual phases of site preparation, most notably including the installation of below-ground utilities and general surveying, dirt-moving, and leveling of the actual ground the factory will be built on.

Perhaps as early as H2 2019, SpaceX will begin to move its first complete or partially-complete BFR spaceship prototype from its tented production facility to the Southern Coast of Texas, where it will begin a series of hot-fire hop tests to prove out its Raptor engines, aerodynamic characteristics, structural composition, and more.

Tesla annihilates Wall Street expectations with strong Q2 delivery showing

Published

on

Tesla (NASDAQ: TSLA) beat Wall Street expectations of 406,000 vehicles delivered in Q2 by reporting 480,126 deliveries for the three months ending in June.

Tesla reported it delivered 467,762  Model 3 and Model Y units, while 12,364 Model S, Model X, and Cybertrucks switched hands during the quarter. The Model S and Model X were officially sunset this past quarter and will no longer be part of the company’s Production & Delivery reports moving forward.

The quarter is a pleasant surprise and a good rebound from Q1, when Tesla slightly missed the Wall Street consensus of 365,645 cars by reporting 358,023 deliveries for the first three motnhs of the year.

Energy storage deployments also provided some strength in Tesla’s delivery report, hitting 13.5 GWh for Q2. This is a particular division of Tesla’s business that has been overwhelmingly robust over the past few years, truly being a strong point of the company’s overall model.

For the year, Tesla analysts still predict deliveries to trend in the 1.69 million unit region, a modest 3 to 5 percent increase from the 1.64 million cars the company delivered last year. Tesla will likely return to more sequential and noticeable year-over-year growth as the Cybercab project starts to ramp up considerably in the next few years.

Tesla has some other potential catalysts to spur vehicle deliveries, too. Not only is it expecting Cybercab to truly start making a change in the next few years, but other vehicles could be entering the company’s lineup.

Tesla sends production Cybercab with no steering wheel, pedals to on-road testing

The slightly longer Model Y L has been a highly speculated release candidate in the U.S. It has already done incredibly well in China, and U.S. buyers have been wanting slightly more interior space than the Model Y. Now that the Model X is gone, it is more needed than ever.

Q2 highlights a pretty stable automotive division within Tesla, and no true concerns arise from these figures, especially considering it managed to beat expectations convincingly.

Tesla Optimus project fires up as Musk sees production line progress

Tesla CEO Elon Musk posted a photo of himself standing with the Optimus production team inside Tesla’s Fremont factory, arms crossed amid workers in hard hats and safety vests. The image captures a pivotal industrial shift: the same facility space once dedicated to building Tesla’s flagship Model S sedan and Model X SUV is now home to the company’s humanoid robot manufacturing line.

Tesla’s Fremont Factory, acquired in 2010 from the former NUMMI joint venture between Toyota and GM, has been the company’s original U.S. manufacturing hub since Model S production began in 2012.

The Model X followed soon thereafter. These premium vehicles offered lower annual volumes, recently around 30,000 combined, compared to the high-volume Model 3 and Model Y lines that continue around the site. Over their combined run, the S and X accounted for roughly 610,000 units.

In late January 2026, during Tesla’s Q4 2025 earnings call, Elon Musk announced the end of Model S and Model X production in Q2 2026. The final vehicles rolled off the line in early May. Rather than retooling for another vehicle, Tesla chose to convert the dedicated S/X assembly area into a dedicated Optimus Gen 3 production line.

Model 3 and Y manufacturing remains unaffected. Tesla’s official Fremont Factory page now lists Optimus alongside the 3 and Y as core products.

The conversion was executed with remarkable speed. After production stopped, crews dismantled the existing vehicle line and installed entirely new modular equipment—including lines sourced from Germany and dozens of sub-lines for actuators, batteries, and other components—in roughly four months.

Musk described the timeline as “insanely fast,” noting it would be unprecedented for any other manufacturer. Initial Optimus output is expected to ramp slowly due to the robot’s roughly 10,000 unique parts and the brand-new production processes involved. The Fremont line targets an eventual capacity of 1 million Optimus units per year.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go

Optimus Development Timeline

  • August 19, 2021: Optimus (then called Tesla Bot) formally announced at Tesla’s first AI Day. A concept video showed a person in a suit demonstrating the vision for a general-purpose humanoid capable of dangerous, repetitive, or boring tasks using the same AI architecture as Full Self-Driving.
  • 2022: Early prototypes displayed. At the second AI Day in September, semi-functional units demonstrated walking across a stage and basic arm movements
  • 2023: September videos showed improved capabilities, including sorting colored blocks, precise limb awareness, and holding a Yoda pose.
  • 2024-early 2025: Factory integration videos showed Optimus navigating workspaces and handling objects like battery cells.
  • January 2026: Gen 3 mass-production activities began at Fremont, with reports of over 1,000 Gen 3 units already operating inside the factory for real-world learning and AI training
  • April 2026: Musk confirms Optimus production on converted Fremont line would begin in late July or August 2026. The Gen 3 reveal, originally eyed for Q1, was pushed closer to production start. A second, much larger Optimus factory at Giga Texas is under construction, with volume production targeted for Summer 2027 and long-term capacity of 10 million units annually
  • July 1, 2026: Musk’s on-site visit and team photo confirm the Optimus line is operational and the transition is actively progressing

Tesla positions Optimus as potentially its largest project ever, leveraging vertical integration, AI expertise, and car-like manufacturing know-how to scale humanoid robots first for its own factories and later for broader industrial and consumer use.

The Fremont conversion serves as a critical proving ground for this ambitious new chapter in Tesla’s already-rich history.

Tesla short seller Michael Burry, the subject of the film “The Big Short,” where he was portrayed by Steve Carell, has revealed he has opened a new bet against the stock.

In a new update to his Substack newsletter in a post titled “Trading Post June 30, 2026,” Burry revealed a new set of bets against Tesla, Caterpillar, NVIDIA, Applied Materials Inc., and the iShares Semiconductor ETF.

In regard to Tesla, Burry wrote:

“And finally I shorted Tesla at 416.22. Happy it jumped back to this level.”

This means Burry likely opened his new short position after the company’s recent rally on Wall Street, which saw Tesla shares sink in mid-May, only to recover to well over the $400 mark. Currently, shares trade at around $427.

The company saw a big Tuesday as shares climbed considerably, over 10 percent. The size of the Tesla short was not provided, nor did Burry give any information on the position’s structure, the number of shares, dollar value, or whether options were used in the short.

The Tesla and SpaceX merger everyone is talking about is quietly building

Over the years, Burry has been one of the more vocal critics of Tesla, calling its share price “media inflated,” and saying it was “ridiculously overvalued” as recently as December.

The company has largely transitioned away from being known as an automotive company and instead is much more widely regarded as an AI play, mostly due to its Full Self-Driving efforts, Optimus robot development, and data collection related to both.

This has not pulled those skeptics away from being vocal about their distaste for how Tesla is valued, but there’s no denying that the company is a global force in many things, including sustainable energy, automotive, and AI.
