SpaceX Starship factory breaks ground on an even bigger ‘high bay’

Published

SpaceX appears to have more or less broken ground on a new, even bigger ‘high bay’ assembly facility at its Boca Chica, Texas Starship factory.

Barely one year ago, SpaceX erected the first prefabricated steel sections of what eventually become its Starship factory ‘high bay’ – a spartan 81m (~265 ft) tall designed at the most basic level to shield final Starship and Super Heavy booster assembly from the elements. Situated near the southernmost tip of Texas and just a few miles west of the Gulf of Mexico, those “elements” can be less than pleasant at SpaceX’s primary Starship factory, ranging from sauna-like heat and humidity and mosquitoes the size of quarters to regular downpours, thunderstorms, tropical conditions, and even hurricanes.

While a great deal of work at Starbase is still done out in the open with little more than an umbrella as protection, SpaceX has nevertheless worked to find a middle ground where the most sensitive work (mainly structural welding) can be mostly shielded from wind and rain. First, SpaceX built a (relatively) tiny ‘windbreak’ too small for much of anything. Two years later, the windbreak is partially used for Starship nose section assembly – when a nose cone is stacked on and welded to a separate stack of four steel rings.

A few months after the triangular windbreak was fully finished, SpaceX started work on a larger box-like building that would eventually be known as the Starship factory’s ‘midbay.’ Standing around 45m (~150 ft) tall, the midbay was designed to support the process of assembling Starship tank sections from several stacks of 2-4 steel rings but was – for whatever reason – left too short to support the full Starship assembly process.

Instead, once Starship tank sections were finished, they would have to be rolled out of the midbay for nose installation. Eventually, in July 2020, SpaceX began assembling an even larger ‘high bay’ that would ultimately measure 81m (~265 ft) tall and 20-25m (65-80 ft) wide and deep – easily big enough to fit the company’s existing Falcon 9 or Falcon Heavy rockets with room to spare. More importantly, of course, the high bay was built to be large enough to support Super Heavy assembly from start to finish, giving SpaceX teams a sheltered place to build the largest rocket boosters in history.

As of August 2021, SpaceX’s midbay has supported the assembly of 10 Starship prototypes, 5-6 propellant storage tanks, and several ‘test tanks,’ while the newer high bay has helped SpaceX build three (mostly) complete Super Heavy boosters in 2021. However, working at full speed, SpaceX’s midbay is really only capable of supporting the assembly of one Starship tank section (and more general work on two) at a time and the high bay – while offering at least twice the covered surface area – appears to be limited to simultaneous work on two or three different stacks (boosters, ships, tanks, etc.).

As SpaceX slowly but surely treks towards the end of approximately two years almost exclusively dedicated to building ever-changing prototypes, it’s been clear for a while that the company would need to drastically expand its production facilities to produce the dozens of Starships and boosters CEO Elon Musk has been publicly dreaming of. Even at lower volumes, those existing facilities – while great for producing a dozen or more prototypes per year – would still become a chokepoint for the near-term production of a small fleet of operational Starships and Super Heavies.

In turn, Musk revealed that SpaceX was about to start building “a much larger high bay” adjacent to the existing structure in late July. On August 20th, a little over a year after assembly of the original high bay kicked off, SpaceX began the process of tearing up existing concrete for the even larger bay – breaking ground, at least in a sense. According to Musk, the newest addition to Starbase’s Starship factory will be about 10% taller (~90m vs 81m), substantially wider, and likely a bit deeper than the existing high bay, allowing for the installation of two side-by-side bridge cranes with tracks running the full width of the building.

With at least 2-3 times more surface area than the high bay, the new wide bay should give SpaceX enough space to simultaneously assemble something like 4-8 Starships or Super Heavy boosters. Depending on which direction SpaceX goes, the wide bay could also potentially be large enough for SpaceX to create the first true Starship and Super Heavy assembly lines, though that would be a substantial departure from Starbase’s existing approach to manufacturing.

Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.

The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.

However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.

Multi-Row Climate Control

Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility

One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.

Tesla has improved upon this with the Model Y L:

PowerShare will be included

Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.

Wireless Charging Pad

There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit

Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.

Thermal Management Improvements

These improvements in the Model Y L were seen with thermal management:

  • Up to 15% faster cabin cooling
  • +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
  • 8x more solar energy reflection off of glass roof
  • 30% reduction in solar energy entering the cabin

Demand

Tesla said the Model Y L is almost sold out in the U.S. It comes with

  • 1 year of FSD Supervised
  • 1 year of Supercharging
  • 1 year of Premium Connectivity
  • Free exterior paint color, interior, and wheel option at no additional cost

Tesla CEO Elon Musk denies ridiculous Gigafactory Shanghai rumor

Tesla CEO Elon Musk took to his social media platform X on Thursday night to deny a ridiculous rumor regarding the sale of the company’s Chinese vehicle production plant, Gigafactory Shanghai.

On Thursday, the Wall Street Journal, citing sources familiar with the matter, claimed in a scathing new report that Tesla was exploring a potential sale of the entire China business in an effort to help bolster a potential merger between SpaceX and Tesla.

Musk immediately denied the rumor not once but twice, initially calling it “fake news,” and then calling it “absurdly fake news” in a separate post just a few moments later:

The original poster of the Wall Street Journal article that Musk saw deleted the initial post sharing the headline and the rumored sale of Tesla’s China business.

The report seemed absolutely and unequivocally false to begin with; Tesla’s business in China is among the most important pieces of the company’s business. Not only does the factory supply vehicles for the domestic market, but also for various other markets in Asia and Europe.

China is also one of the largest automotive markets in the world, and Tesla has performed well there despite the robust competition.

The speculation regarding a Tesla and SpaceX merger has started to gain steam this year as the space exploration company went public just a month ago. There has been speculation that Musk will bridge all of his companies under one “umbrella company,” and analysts believe this could happen before the end of the decade.

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

This is the latest iteration of Musk’s very evident war on mainstream media. Reports regarding any of Musk’s companies are quick to get the dreaded “false” or “fake news” response from the CEO when they are unfounded.

Tesla AI boss reveals how big Optimus is going to get

Tesla’s Optimus chief corrected himself on X, confirming a staggering 10 million robot production target.

Tesla’s Optimus program has a new number attached to it, after Ashok Elluswamy, the executive who has run the humanoid robot program since June 2025, posted a three word correction on X Thursday, “Correction, 10 million robots.”

The line clarifies the long term annual capacity Tesla is building toward its planned second Optimus production line at Gigafactory Texas, a figure Musk has cited repeatedly since last year’s shareholder meeting.

The scale is worth noting, because ten million robots a year would mean Tesla building more units annually than most countries sell in new cars. Tesla has framed this as a second line, not the first. The buildout is happening in two phases: a roughly one million unit per year line inside Tesla’s Fremont factory, installed on the floor space vacated when Model S and Model X production ended earlier this year, and a much larger dedicated facility under construction at Giga Texas that broke ground on its first steel structure in May. That Texas facility is the one Elluswamy’s correction refers to, and is expected to reach volume production sometime in 2027.

Tesla Optimus project fires up as Musk sees production line progress

Elluswamy took over Optimus from Milan Kovac last summer and has spent the months since talking up the program’s trajectory. Elon Musk has also floated the ten million figure at Tesla’s 2025 shareholder meeting.

Ending Model S and Model X production to make room for the first Optimus line was one of the more consequential manufacturing decisions in the company’s recent history, retiring two flagship vehicles in favor of a robot that has yet to enter mass production. Musk has previously estimated per unit production costs at $20,000 to $25,000 once Tesla reaches a million units a year, though he hasn’t said what that cost looks like at ten times the volume.
