SpaceX rapidly stacks Starship and Super Heavy with ‘Mechazilla’
For the second time ever, SpaceX has used Starbase’s ‘Mechazilla’ tower and arms to stack a Starship upper stage on top of a Super Heavy booster.
This time around, though, SpaceX clearly learned a great deal from its second February 9th Starship stack and was able to complete the stacking process several times faster on March 15th. During the second attempt, depending on how one measures it, it took SpaceX around three and a half hours from the start of the lift to Starship fully resting on Super Heavy. With Stack #3, however, SpaceX was able to lift, translate, lower, and attach Starship to Super Heavy in just over an hour.
Oddly, SpaceX managed that feat without a claw-like device meant to grab and stabilize Super Heavy during stacking operations. For Stack #2, all three arms were fully in play. First, a pair of ‘chopsticks’ – giant arms meant to grab, lift, and even recover Starships and boosters – grabbed Ship 20, lifted it close to 100 meters (~300 ft) above the ground, rotated it over top of Super Heavy, and briefly paused. A third arm – known as the ship quick-disconnect or umbilical arm – swung in and extended its ‘claw’ to grab onto hardpoints located near the top of Super Heavy. Once the booster was secured, the ‘chopsticks’ slowly lowered Ship 20 onto Booster 4’s interstage and six clamps joined the two stages together.
A few hours after the two were clamped together, an umbilical device located on the swing arm extended and connected to Ship 20. It’s unclear if the panel was actually used in any way but the umbilical is designed to connect Starship to ground systems to supply propellant, power, communications, and other consumables. Regardless, the device did appear to connect to Starship. Prior to Stack #3, however, SpaceX removed both of the swing arm’s ‘claws,’ meaning that it had no way to grab onto Super Heavy. That diminished capability clearly appeared to have zero impact on the ease or speed of the stacking process given that it was completed a full three times faster than Stack #2.
That could imply that the claw is either completely unnecessary or only needed when attempting stacking operations in extreme winds. What is clear is that the claw removal likely only shaved a handful of minutes off of the full stacking process. What really saved time on Stack #3 was a faster lift and fewer pauses throughout – especially while lowering Starship the last several meters onto Super Heavy. During Stack #2, SpaceX took close to an hour and a half to fully lower Ship 20. The same sequence took just ~20 minutes during Stack #3.
Still, after the impressively rapid one-hour stack, it then took SpaceX close to two hours to connect the swing arm’s umbilical to Starship, leaving plenty of room for improvement. Ultimately, assuming SpaceX can speed up the start of the stacking process and replicate its Starship success with Super Heavy, which will also need to be grabbed and installed on an even more complex launch mount, it’s possible that Starbase’s orbital launch integration system is already capable of supporting multiple Starship launches per day. Of course, SpaceX has yet to demonstrate that the orbital launch site can be turned around in a matter of hours after being subjected to the violence and stresses of a Starship launch.
More significantly, SpaceX has never even attempted an orbital Starship launch, recovery, or reuse. That leaves the company in the unusual position of building and testing expensive, specialized support equipment before it actually knows that the rocket that equipment is designed to support is in any way capable of taking advantage of it. For an orbital spacecraft the size of Starship, only the Space Shuttle comes anywhere close and NASA’s all-time record for orbiter turnaround was 54 days. SpaceX has technically flown two Falcon 9 boosters twice in 27 days but no matter how impressive that feat is, reusing a far smaller suborbital booster is vastly easier than reusing a massive orbital spacecraft.
At the end of the day, it’s not really SpaceX’s fault that it’s still waiting for permission to attempt orbital test flights. Nonetheless, the growing gap in maturity between Starship and Super Heavy and the orbital launch site designed to support them continuously raises the risk that SpaceX will have to extensively redesign the rocket, its support equipment, or both if significant problems arise during orbital test flights.
Up next, there’s a chance that SpaceX could attempt to cryoproof Starship while on top of Super Heavy – or perhaps both stages at once. While SpaceX has performed more than half a dozen cryoproofs of Ship 20 and Booster 4 using the orbital launch site’s propellant storage and distribution system, it hasn’t fully tested the hardware needed to route hundreds of tons of propellant hundreds of feet into the air – essential for full-stack testing and launch operations.
Tesla CEO Elon Musk announced that the company will extend Cybertruck production slightly to handle its extensive order backlog.
On Wednesday, Musk announced that “In order to work through more of the Cybertruck order backlog, production will be extended through the end of summer 2027.”

Tesla has already attempted to simplify its last months of production for the Cybertruck by eliminating several trim levels and only offering the Cyberbeast, the most expensive trim that starts at $109,990. The other two trim levels, the Cybertruck All-Wheel-Drive and Premium All-Wheel-Drive have both been discontinued.
There has been plenty of backlash against Tesla’s decision to ax the Cybertruck, but the company’s forecast prioritizes Cybercab and autonomy. Factory space at Gigafactory Texas that is not necessary is now being set aside for the Cybercab as the company truly embraces its “transportation-as-a-service” model.
There is still a slim chance the Cybertruck survives. Last evening, Tesla upfitter Unplugged Performance offered to take the Cybertruck line off of Tesla’s hands and continue building it, along with a CyberSUV.
Nevertheless, Tesla seems to be ending the Cybertruck on its terms after what will be a three-and-a-half-year run. It still does not really feel quite real; I think many of us thought the Cybertruck would be around for years to come.
Musk added more detail, stating that while it was not the smartest move, “there must be some room in this world for sentimentality or what’s the point?”
This is not the smartest move from a profit-maximizing standpoint btw, but there must be some room in this world for sentimentality or what’s the point?

Other EV pickups on the market have experienced a similar fate.
The Ford F-150 Lightning was axed by the Detroit company due to the continued losses the company took from sales. That truck was never profitable, and Ford is still taking a quarterly loss in its EV side. However, things are moving along as it has plans for a mass market EV pickup, which will likely gather some substantial demand if Ford can get it just right.
Perhaps another extension or even a total change of heart might come. Only Musk knows.
In a sudden and closely watched milestone, Tesla Robotaxi has edged past Waymo on the Texas Department of Motor Vehicles automated vehicle registry. As of November 10, Tesla lists 1,302 registered vehicles under Tesla Robotaxi, LLC, compared with Waymo’s 1,297.
The flip is narrow, but real, according to the State’s books. Tesla’s Texas fleet, following an expansion on November 10, now consists of 729 Model Ys and 573 purpose-built Cybercab vehicles. Waymo’s roster is dominated by the Jaguar I-PACE and a growing number of Zeekr-based Ojai minivans.
NEW: Tesla Robotaxi just added 20 Tesla Model Ys to its fleet. The Texas fleet now stands at 1302 vehicles.

Those figures come from the same public TxDMV automated vehicle listings that independent trackers have monitored since a Texas law required operators to disclose fleet sizes.
The scale of Tesla’s climb is pretty interesting and shows how much the company has grown its autonomous ride-hailing fleet over the past months. When the registry first became public in late May 2026, Tesla listed just 42 vehicles on it. Meanwhile, Waymo had several hundred vehicles registered to it.
Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’
Since then, Tesla has multiplied its authorized Texas fleet more than thirty times, driven by repeated Model Y additions and a steady build of Cybercabs. Waymo has also expanded, but at a slower pace than Tesla.
It is also important to note that registrations are not necessarily equal to operational fleet. The TxDMV list shows the number of vehicles each company is permitted to run, but it does not report how many are actively carrying riders, which cities they serve, or trip volume. Both companies stage vehicles and run mixed fleets that can include units in testing or temporarily offline.
A lead on the registry therefore signals capacity and regulatory positioning more than immediate ride volume.
Tesla has use the growing authorized fleet to expand its unsupervised service beyond the original Austin geofence area, as now it is flowing into cities like San Antonio and Dallas. The company has highlighted plans for a broader Cybercab deployment, eventually into new states and territories.
Waymo is operating across multiple Texas markets and in other areas of the United States.
Right now, the five-vehicle margin is thin and could reverse with the next large registration from either side. For the moment, however, the public Texas record shows Tesla holding the larger authorized Robotaxi fleet in the state.

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.
