SpaceX prepares new Starship tank for explosive test after rapid construction
Over the last few weeks, SpaceX’s South Texas Starship team has been making progress at a pace unprecedented even for the famously agile rocket company and is moving full speed ahead to kick off a new series of explosive tests as early as this morning.
Ever since SpaceX’s original Starship Mk1 prototype spectacularly failed during a November 2019 pressure test, the company has been rapidly rearranging and modifying the development schedule for its next-generation full-reusable rocket. Be it a side effect or coincidence, SpaceX effectively began closing its Florida Starship factory a week after Mk1’s demise and even shipped some of its Florida-built Starship hardware to Texas in recent weeks. However, most of the Florida workforce (up to 80%) was reportedly redirected elsewhere in the company, avoiding layoffs.
Some portion may have even moved to Texas and joined SpaceX’s Starship Boca Chica facilities. Given just how aggressively SpaceX has been expanding its local facilities and preparing new hardware for the next round of improved Starship prototypes, it seems quite likely that the South Texas outpost did indeed receive an influx of skilled workers. Most recently, the company has demonstrated its rapidly growing expertise in the bizarre art of building steel rockets en plein air by fabricating and integrating new tank domes and steel rings and then shipping the curious contraption to its nearby launch site in a matter of weeks from start to finish.
Although it’s difficult to determine the chronology of every single part of the mysterious new tank, it’s fairly safe to say that work on its structure began less than a week before SpaceX CEO Elon Musk tweeted a surprise update, indicating on December 27th that he was in Boca Chica, Texas working all night on “Starship tank dome production”.
In simple terms, the business half of SpaceX’s next-generation Starship upper stage and Super Heavy boosters are comprised of three main parts, shared by almost all launch vehicles. Both are rocket stages that must be as light as physically possible while supporting thousands of tons worth of supercool liquid oxygen and methane propellant. The majority of a simple rocket is ultimately a duo of cylindrical tanks capped by tank domes – also known as bulkheads. The bottom bulkhead of boosters and upper stages also serves as a mounting point for an engine section, where the vehicle’s rocket engines are attached to the rocket body in order to transfer their thrust throughout the rest of the structure.
SpaceX CEO Elon Musk says that Starship tank domes have turned out to be “the most difficult part of [the rocket’s] primary structure” to manufacture, thus explaining why he was apparently assisting the Boca Chica team all night on December 27th.
Starship Mk1 exploded on November 20th, 2019 during a nonflammable propellant loading test, a failure that unofficial videos have compellingly linked to the weld joint connecting the rocket’s upper tank dome to its cylindrical tank. That section of the rocket began leaking cryogenic propellant moments before the entire upper dome tore off the rest of the vehicle and launched hundreds of feet into the air.
All hail Baby Tank
In an apparent response to the unsatisfactory results of Starship Mk1’s manufacturing methods, SpaceX has rapidly initiated an already-planned upgrade of its Starship facilities and manufacturing methods in South Texas, taking delivery of a wealth of new tools over the last several weeks. Most recently, SpaceX’s latest step towards demonstrating that it has substantially improved manufacturing quality arrived in the form of a single propellant tank – the same diameter as Starship Mk1 but much shorter than any possible flight hardware.
Quickly nicknamed Bopper (short for Baby Starhopper) by locals and close followers, the miniature Starship test article came together at a truly spectacular pace. Comprised of two single-weld steel rings and two brand new tank domes, it appears that all four of the components were nothing more than parts and steel stock less than three weeks ago. The first sign of activity came around December 19th, when technicians began placing pressed steel sections onto a bulkhead (dome) assembly jig – used to precisely hold the pieces in the right shape and place as they are welded together.
Incredibly, aside from taking less than three weeks to go from miscellaneous parts to an assembled Starship tank delivered to the test site, SpaceX technicians appeared to finish stacking and welding its two halves (each a ring and a dome) perhaps a handful of hours before it was lifted onto a transporter and driven to the launch pad.
Even for SpaceX, moving a prototype from factory to test site hours after its primary structure was welded together represents an almost unfathomably fast pace of work – truly unfathomable in traditional aerospace. Whether or not such a pace of work is smart, sustainable, or worth it remains to be seen, but SpaceX is nevertheless on track to pressure test its new mini Starship tank as early as this morning, potentially resulting in another spectacular overpressure event (i.e. explosion).
If the tank survives up to or beyond the pressures SpaceX has designed it to, it’s safe to say that the next full-scale Starship prototype could come together far sooner than almost anyone might have expected.

SpaceX just cleared a key FCC hurdle in its fight with Verizon and AT&T
The FCC accepted SpaceX’s bid for Grain’s 800 MHz spectrum, opening review for Starlink Mobile.
The Federal Communications Commission has formally opened its review of SpaceX’s plan to buy a nationwide block of 800 MHz spectrum from Grain Management, moving Starlink Mobile one step closer to operating as a full U.S. wireless carrier.
In a public notice issued Tuesday, the FCC’s Wireless Telecommunications Bureau said it accepted for filing the applications to transfer control of two Grain license companies, Prism License Co. 1 and Prism License Co. 2, to Starlink Spectrum Holdings, a wholly owned SpaceX subsidiary. The deal covers 546 paired licenses across 3,224 counties, reaching roughly 100% of the U.S. population in all 50 states, Washington, D.C., Puerto Rico and the U.S. Virgin Islands. The proceeding sits under WT Docket No. 26-313.
Acceptance is not approval. It means the applications cleared an initial review and the public comment window is now open. Comments and petitions to deny are due December 1, and oppositions are due December 8. The bureau also said the conditions attached to Grain’s July purchase of the licenses from T-Mobile, which require rapid buildout for terrestrial and direct to device service, would carry over to SpaceX if the transfer is approved.
SpaceX announced the agreement on October 8, saying the new airwaves would let Starlink Mobile’s signal reach phones inside buildings, something its 2 GHz spectrum from EchoStar cannot do as well. The portfolio includes up to 14 MHz of paired spectrum in the 817 to 824 MHz and 862 to 869 MHz bands, which most existing phones already support. Elon Musk called it “the last critical piece of the spectrum puzzle needed for SpaceX to provide complete phone coverage in America.”
According to the filing, SpaceX would hold up to 89 MHz of total spectrum in any given market after the deal closes, including up to 14 MHz below 1 GHz. That is far under the 385 MHz threshold the FCC uses to flag a transaction for closer competitive scrutiny, and well short of the roughly 300 MHz each of AT&T, Verizon and T-Mobile holds.
Tuesday’s notice does not decide how SpaceX can use the spectrum from orbit. A separate application SpaceX filed on October 27 seeking authority to provide supplemental coverage from space on the same frequencies, along with related waiver requests, is still pending before the commission.
The ground network is already taking shape. Last week, SpaceX picked Qualcomm to supply radios, baseband units and software for a nationwide 5G build, with deployment across tens of thousands of U.S. cell sites starting in 2027. The FCC also voted on October 29 to advance a proposal opening another 482 MHz to direct to device service, though AT&T, Verizon and T-Mobile hacritive pushed to strip nearly 300 MHz from it. SpaceX President Gwynne Shotwell has said service on SpaceX’s own airwaves is targeted for early 2028.
A Tesla upfitter has offered to take over Cybertruck lines from the company in a last-ditch effort to save the all-electric pickup from being completely canceled in the middle of 2027.
Unplugged Performance, the Hawthorne, California-based Tesla aftermarket specialist, has publicly offered to take over Cybertruck production from Tesla, funding the effort “through a consortium of investors.”
An open offer to Tesla: We fully support putting Cybercab first, and we’d be glad to take the Cybertruck line off your hands.
We’d fund it with a consortium of investors and run it at no cost to Tesla’s floor space, headcount, or focus. All of that goes to Cybercab. Cybercab gets first call on battery cells too. We’ll wait our turn.
Tesla gains incremental profit: a license fee, plus FSD and Robotaxi network revenues on every vehicle built.
We’d build the Cybertruck, a three-row CyberSUV, and an unmanned CyberCargo hauler. More autonomous miles, across every surface of this planet and beyond.
Worth a conversation?— UP (@UnpluggedTesla) November 10, 2026
The proposal comes as Tesla prioritizes its Cybercab Robotaxi program and prepares to wind down Cybertruck assembly at Gigafactory Texas around mid-2027.
Founded in 2013 by Ben Schaffer and located adjacent to Tesla’s Design Studio and SpaceX, Unplugged Performance has become a leading provider of premium upgrades for Tesla vehicles, including extensive Cybertruck packages under its UP INVINCIBLE line.
Through its UP.FIT division, the company has also developed purpose-built police and fleet versions of the Cybertruck, including deliveries to agencies such as the Las Vegas Metropolitan Police Department.
In an X post on Tuesday, Unplugged said:

The arrangement would free Tesla resources and manufacturing capacity for Cybercab while allowing continued production of the stainless-steel pickup and expanded variants. Unplugged Performance indicated it would wait for battery cells after Cybercab needs are met and would generate ongoing revenue for Tesla through licensing and software/network services on the vehicles it produces.
Following strong initial interest, Unplugged Performance posted a follow-up inviting potential investors and strategic partners to email cyber@unpluggedperformance.com. The company clarified that the outreach is solely to gauge interest and does not constitute an offer to sell securities or acceptance of funds at this stage.
The proposal arrives shortly after Elon Musk indicated that Cybertruck production in Texas would be phased out by roughly the middle of 2027 to expand Cybercab output.
Whether Tesla engages with the offer remains to be seen, but the public overture highlights both the aftermarket specialist’s deep experience with the Cybertruck platform and the growing focus on autonomy within Tesla’s manufacturing plans.
Elon Musk said the Tesla Cybercab will perform “a majority of all passenger miles” where it is allowed to operate and that point is “obvious to anyone with eyes and a brain.”
Musk used the point to double down on the company’s decision to ax the cult-favorite Cybertruck, as its production space will be removed and transitioned into additional Cybercab lines. The move has catalyzed a polarizing conversation on whether its right or wrong.
Whatever side you are on — it’s happening.
Dodge ended the Viper.
Audi retired the R8.
Mitsubishi said goodbye to the Lancer Evo.
Ford bid farewell to the Bronco (at one point).
Chevrolet sunset the Camaro.Tesla is ending the Cybertruck. I’m pissed. I’m upset.
Fans of those five automakers mentioned did the same thing. It happens. It sucks. I don’t like it.
But I still love Tesla. I love my Model Y. I hoped to be in a Cybertruck in a little under two years.
I won’t be. But I still won’t put my family in anything else. Too safe. Too advanced. Too much better than everything else.

Regardless, Musk seems to be getting to the point that he is done talking about the choice. At some point, you have to think that this was truly a difficult decision for him and the company as well, and this is not something he took lightly. In fact, he’s probably a little bit disappointed with it, too.
But the point remains that the Cybertruck is gone. Musk’s focus is purely on developing an autonomous platform that the world will utilize for transportation, and he’s telling you that anyone “with eyes and a brain” can see it:
@PalmerLuckey @carlhancock Cybercab will do a majority of all passenger miles in any jurisdiction where it is not prohibited by law.
Obvious to anyone with eyes and a brain.

Tesla is betting that all of its passengers in the future will be okay with not owning their own personal cars and will be fine with ride-hailing for the rest of their lives. Every dinner, every errand, every trip to the airport and transportation thereafter, will all be operated by ride-sharing, and in Tesla’s perfect world, it will happen in a Cybercab.
As of now, Cybercab is only active in Austin, but it has been spotted all over the country with a driver behind the wheel in those prototypes. In Austin, the car has no steering wheel or pedals for people to control the vehicle.
The Cybertruck dilemma is one that has truly come across the entire Tesla community and while it seems to be a great idea to keep it because people love it, the business side of things is steering Musk and Tesla in another direction.
