The first 9-meter (29.5-foot) diameter composite propellant tank dome for SpaceX’s full-scale BFR spaceship prototype has been spotted more or less complete at the company’s temporary Port of Los Angeles facility, unambiguous evidence that SpaceX is continuing to rapidly fabricate major components of its next-generation rocket.

Speaking at a dedicated BFR update event in mid-September, CEO Elon Musk foreshadowed as much, and recent updates have reiterated just how committed SpaceX is to BFR and just how keen the company is to waste no time at all.

“We’ve built the first cylinder section…and we’ll be building the domes and the engine section soon.” – SpaceX CEO Elon Musk, September 2018

During that September 17th presentation, Musk did not parse his words despite a self-admitted tendency to look at SpaceX’s development program timelines (Falcon 9, Falcon Heavy, Dragon, BFR) through rose-tinted glasses. Just two months after he uttered the quote above, SpaceX has visibly either finished or nearly finished a 9-meter diameter BFR spaceship (BFS) tank dome.

Due to SpaceX’s opaque treatment of development programs (both literally for the tent and figuratively for official updates), it’s possible that this may even the second dome completed so far. Either way, it can be extrapolated – assuming that the layout of BFR 2017 is generally representative of BFR 2018 – that the first spaceship prototype will require two or three roughly identical tank domes. If the common-dome tank layout is basically the same (disclaimer: it might be quite different), then SpaceX may end up mounting BFS’ 7 Raptor engines almost directly to the rear of the bottom tank dome, requiring either significant structural reinforcement or a second uniquely-engineer and optimized dome.

Judging from SpaceX’s and Musk’s desire to make reusable rockets as reliable as (if not even more reliable than) commercial airliners, the safest form of mass-transit humans have created, it seems more likely than not that Raptor and BFR will continue SpaceX’s practice of quite literally surrounding each engine with thrust-transmitting structures that simultaneously act as armored shields. In the event that a Merlin engine fails on Falcon 9 or Heavy, each booster’s octaweb contains nine separate armored chambers that exist to isolate each engine in the event of a catastrophic failure. In fact, a Merlin failure – the only such in-flight failure known – during SpaceX’s CRS-1 Dragon launch in 2012 demonstrated the efficacy of this design, preventing the failure of just one of nine engines from causing total mission failure.

Rise of the ‘hexaweb’?

To replicate that design strategy on BFR (both booster and spaceship) would be an act of simple pragmatism – it’s always preferable to design for survivability and reliability than to couch launch and mission success primarily on the reliability of individual components. Because SpaceX chose not to share similarly detailed cutaways of BFR’s updated 2018 design, it’s unclear if the spaceship’s engine section (“hexaweb”, to borrow from “octaweb”) has changed dramatically.

Given the unexpected decision to move entirely away from a version of Raptor specifically optimized for vacuum operation for BFR’s first iteration, as well as the new presence of ~90 cubic meters of storage bins around the circumference of the spaceship’s aft, it’s possible that SpaceX will opt for a design more reminiscent of the Falcon family’s octaweb.

 

Regardless, the appearance of a completed BFS tank dome is a major development on the vehicle’s path to integrated testing and paves the way for the fabrication of additional tank domes, barrel sections, engine sections, and more. Particularly obvious and noteworthy will be the fabrication of the prototype spaceship’s pointed cone-shaped nose section, its large tripod fins/wings/legs, and its two forward canard wings.

With all three fins/wings installed, BFS – in its current iteration – would have an unbelievable circumference of ~67 meters (220 feet) and a ‘finspan’ of perhaps 21 meters (~70 feet) tip to tip. BFS is going to be a very hard spaceship to hide.

Tesla is not releasing Unsupervised FSD to regular customers yet, but the company seems to be preparing something special for its FSD users nonetheless. 

This was, at least, according to Elon Musk in a recent post on X.

Tesla FSD V14

Tesla’s FSD program has been deemed by Elon Musk as one of the key factors that would determine the company’s long term success. Over the past months, however, Tesla has mostly been focusing on the rollout and ramp of its Robotaxi program in Austin and the Bay Area. Tesla’s Robotaxi service uses Unsupervised FSD, which is not yet released to customers.

However, in a post on X, Musk stated that Tesla is preparing its next big update for its consumer-grade FSD system—V14. Musk did not provide a lot of details about FSD V14’s capabilities, but the CEO did state that the update will feature a 10X higher parameter count, among other improvements.

“The FSD release in about 6 weeks will be a dramatic gain with a 10X higher parameter count and many other improvements. It’s going through training & testing now. Once we confirm real-world safety of FSD 14, which we think will be amazing, the car will nag you much less,” Musk wrote in his post.

Tesla Unsupervised FSD Rollout

During the second quarter earnings call, Tesla executives were asked for a timeline on the rollout of Unsupervised FSD to consumer vehicles. In his reply, Musk stated that he believes Unsupervised FSD will be available for consumers in certain geographies. He did explain that Tesla will be extra careful with the system’s release. 

“We are getting there. I think it will be available for unsupervised personal use by the end of this year in certain geographies. We are just being very careful about it. This is not something we should rush,” Musk said, adding that “I am confident that by this year, within a number of cities in the US, it will be available to end users.

Elon Musk has reaffirmed the Tesla Semi’s mass production date. He mentioned the update in a post on social media platform X during the weekend.

Tesla Semi Factory

The Tesla Semi was initially unveiled in late 2017, and its first deliveries were held in December 2022. Since then, Tesla has only been delivering the Semi to a handful of customers while it builds a dedicated factory for the Class 8 all-electric truck near its Giga Nevada facility.

Drone flyovers of the Tesla Semi factory over the past months have suggested that progress in the construction of the facility has been steady. More recent flyovers have even suggested that Tesla is now busy outfitting the facility with the necessary equipment for the mass production of the Semi.

Elon Musk’s Recent Comments

In a recent comment on X, Elon Musk reiterated the idea that the Semi was indeed expected to be mass produced in 2026. Musk shared his update as a response to a Tesla bull who recalled that Bill Gates did not believe that the Semi was feasible due to the limitations of battery technology. In his response, Musk posted a laughing emoji together with “Tesla Semi will be in volume production next year.” 

The Tesla Semi factory near Giga Nevada is expected to be capable of producing 50,000 units of the Class 8 all-electric truck per year. While this number may not be attained by the facility right out of the gate, it would only be a matter of time before the factory manages to hit an optimal production rate.

In a video posted on social media earlier this year, Dan Priestley, who leads the Semi program at Tesla stated that the company is preparing for volume production over the coming quarters. With such a pace, the factory should be able to mass produce the Semi in 2026.

Elon Musk confirms Tesla AI6 chip is Project Dojo’s successor

Tesla’s AI5 and AI6 chips are expected to be rolled out to the company’s consumer products.

Earlier this week, reports emerged stating that Tesla has stepped back from its Project Dojo initiative. While the reports were initially framed as a negative development for the electric vehicle maker’s autonomous driving efforts, CEO Elon Musk later noted on X that Tesla was indeed halting its Dojo initiative.

Elon Musk’s Confirmation

As per Musk, Tesla was shuttering Project Dojo because it does not make sense for the company to divide its resources and scale two different AI chip designs. Dojo, after all, is designed to train the company’s autonomous driving program, and thus, it would not be rolled out to Tesla’s consumer products.

In a series of posts on X, Musk stated that it would make sense to just use Tesla’s AI5/AI6 to train its FSD and Autopilot systems. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk said.

Tesla’s AI5 and AI6 chips are expected to be rolled out to the company’s consumer products, from Optimus to the Cybercab to the next-generation Roadster.

AI6 is Dojo’s Successor

What was particularly interesting about Musk’s comment was his mention of using AI5/AI6 chips for training. As per Musk, this strategy could be seen as “Dojo 3” in a way, since the performance of Tesla’s AI5 and AI6 chips is already notable. Musk’s comment about using AI6 chips for training caught the eye of many, including Apple and Rivian alumnus Phil Beisel, who noted that “AI6 is now Dojo.”

“Dojo is Tesla’s AI training supercomputer, built around a custom chip known as the D1. The D1 and AI5/AI6 share many core design elements, particularly the math operations used in neural networks (e.g., matrix multiplication) and highly parallel processing.

“Dojo had a unique feature: chips arranged in a 5×5 grid using a system-on-wafer design, with etched interconnects enabling high-speed data transfer. In a sense, Dojo will live on as the generalized AI6. Going forward, all efforts will focus on AI6,” the tech veteran wrote in a post on X.

Elon Musk confirmed the Apple alumnus’ musings, with the CEO responding with a “bullseye” emoji. Musk is evidently excited for Tesla’s AI6 chip, which is expected to produced by Samsung’s upcoming Texas fabrication facility. In a post on X, Musk stated that he would personally be walking Samsung’s line to accelerate the output of Tesla’s AI6 computers.
