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.

Elon Musk confirms Tesla Semi will enter high-volume production this year
Musk shared his update in a post on social media platform X.
Elon Musk has confirmed that Tesla will begin high-volume production of the Class 8 all-electric Semi this year.

Musk confirms Tesla Semi production ramp
Tesla CEO Elon Musk reaffirmed on X that the Semi is finally moving into volume production, posting on Sunday that “Tesla Semi starts high volume production this year.”
The update comes as Tesla refreshed its Semi lineup on its official website, an apparent hint that the program is transitioning from limited pilots into wider commercial deployment. As per Tesla’s official website, two variants of the Semi will be offered to consumers: Standard and Long Range.
The Standard trim offers up to 325 miles of range with an energy consumption rating of 1.7 kWh per mile and a gross combination weight rating of 82,000 pounds. The Long Range version pushes driving range to 500 miles, with Tesla noting a higher curb weight of about 23,000 pounds, likely due to a larger battery pack.
Both trims support fast charging, with Tesla stating that the Semi can recover up to 60% of its range in 30 minutes using compatible charging infrastructure.
Broader Tesla Semi rollout
Tesla has already delivered production Semi units to select partners, including snack and beverage giant PepsiCo as well as logistics behemoth DHL, which confirmed that its truck operates daily in California, traveling roughly 100 miles per day and requiring charging just about once a week.
The company has also partnered with Uber Freight, as noted in a Benzinga report, with Tesla executives previously describing the agreement as a way for fleet operators to experience the Semi’s lower operating and maintenance costs firsthand.
With Musk now publicly committing to high-volume production, the Semi appears poised to move beyond pilot programs and into scaled commercial use, an important step in Tesla’s wider push to electrify heavy-duty and long-range trucking.

Tesla tops France reliability rankings, beating Toyota for the first time
The milestone was celebrated by CEO Elon Musk on social media platform X.
Tesla has overtaken Toyota to become France’s most reliable car brand in 2025, as per a new nationwide reliability ranking published by Auto Plus magazine.
The milestone was celebrated by CEO Elon Musk on social media platform X.
Tesla tops reliability ranking in France
Tesla ranked first overall in Auto Plus’ 2025 reliability study, surpassing long-time benchmark Toyota across all powertrain types, including gasoline, hybrid, and electric vehicles.
The ranking, published on February 6, 2026, evaluated early problems reported in 2025 on vehicles registered in France since January 1, 2018, with fewer than 150,000 kilometers on the odometer, as noted by a Numerama report. This marked Tesla’s first appearance in the magazine’s reliability rankings, which was enabled by the company’s growing vehicle population in the French market.
According to the publication, Tesla vehicles showed no recurring major defects beyond isolated suspension arm issues, which are covered under the company’s four-year or 80,000-kilometer warranty. Other reported issues were described as minor, including occasional screen glitches and door handle concerns.
Why this ranking differs from earlier criticism
Tesla’s top placement contrasts sharply with past assessments from the German Automobile Club (ADAC), which previously ranked the Model 3 and Model Y low in its technical inspection reports. Auto Plus noted that those inspections were focused heavily on factors such as brake disc wear, which are not necessarily the best benchmarks for overall vehicle reliability.
By focusing instead on real-world reliability data and early ownership issues, Auto Plus’ methodology offered a broader picture of how vehicles perform over time rather than how individual components age under inspection standards. The publication emphasized that electric vehicles, with far fewer moving parts than combustion-engine cars, are not inherently less reliable.
While the ranking supports the case that electric vehicles can match or exceed the reliability of traditional brands, the magazine acknowledged limitations in its analysis. Still, Tesla’s debut at the top of the list underscores how perceptions of EV durability are shifting as more long-term data becomes available in major automotive markets like France.

Tesla’s Sweden standoff draws UAW support as unions widen pressure campaign
In a post shared on social media, the United Auto Workers stated that it stands with IF Metall workers who are striking against Tesla Sweden.
The United Auto Workers (UAW) has publicly expressed solidarity with Swedish union IF Metall as its strike against Tesla continues, adding international attention to the extended labor dispute in the European country.
UAW supports IF Metall’s strike
In a post shared on social media, the United Auto Workers stated that it stands with IF Metall workers who are striking against Tesla Sweden. UAW Region 8 Director Tim Smith stated that the union fully supports IF Metall’s efforts to secure a collective bargaining agreement with the automaker.
“UAW stands with IF Metall workers on strike against Tesla, fighting for a collective bargaining agreement. UAW Region 8 Director Tim Smith pledged the UAW’s full support and solidarity,” the UAW International Union stated in its post.
IF Metall launched its strike against Tesla Sweden in late 2023 over the electric car maker’s refusal to sign a collective agreement. The action has since been supported by other unions through sympathy strikes affecting ports, logistics, and service operations.
Tesla Sweden has maintained that it complies with Swedish labor laws and offers competitive pay and benefits, though the company has not publicly commented on the UAW’s latest show of support.
Tesla owners get union attention
Pro-union groups in Sweden have recently expanded their outreach beyond Tesla’s facilities and workforce. Activists have begun distributing informational leaflets against the EV maker directly on Tesla vehicles parked across Stockholm, as per a report from Swedish outlet Dagens Arbete.
The yellow slips, designed to resemble parking notices, urge regular Tesla owners to pressure the company into signing a collective agreement. Organizers involved in the effort have argued that the leaflets are intended to simply inform consumers rather than single out individual owners. When owners are present, however, activists stated that they explain the dispute verbally.
Tesla has not issued a public response regarding the leaflet distribution campaign as of writing.
