SpaceX bumps Starship booster engine count, ramps up Raptor factory
SpaceX CEO Elon Musk has confirmed that Starship’s Super Heavy booster will have at least one more engine than expected after hardware spotted at its Boca Chica, Texas factory indicated as much.
Simultaneously, Musk revealed that SpaceX’s Hawthorne, California factory and headquarters is now producing Raptors at a rate that will likely make it the company’s most numerous product (outside of Starlink) in the near future.
Musk says that Super Heavy boosters will “initially” have 29 Raptor engines instead of 28 engines and could even be upgraded to 32 engines down the road. In 2020, the vehicle’s design was updated, dropping from 31 to 28 engines for unknown reasons before SpaceX began work on the first real Super Heavy hardware. Known as BN1 or booster number 1, that rocket was stacked to its full ~70m (~230 ft) height but ultimately turned into a manufacturing pathfinder (i.e. practice) after Super Heavy’s design changed once again.
Who or what has been causing those seemingly endless design changes is unclear but SpaceX is finally at a point where any more major changes will explicitly delay plans for Starship’s inaugural spaceflight – deemed an “orbital test flight” by the company. It remains to be seen if SpaceX will actually attempt to recover the first booster(s) after those initial quasi-orbital test flights but we now have a better idea of what those Super Heavies might look like.
Namely, Musk seems to indicate that even the very first flightworthy prototypes will be outfitted with a full complement of Raptors – seemingly nipping in the bud the possibility of a booster debuting with the fewest possible engines. In the case of the first few initial orbital launch, that means that SpaceX is happy to risk losing 32-35 engines for every single attempt.
That could imply several things. SpaceX might be extremely confident that early boosters will be recovered. It could have zero faith in the reusability of early flown Raptors, meaning that they’re functionally expendable regardless of the outcome. SpaceX could have also reduced the cost and increased the speed of production to the point that expending dozens of Raptors isn’t a major issue – though ~32 Raptors would cost $8 million even if SpaceX has already hit Musk’s long-term “<$250k” per-engine target.
However, Musk also says that SpaceX has ramped up Raptor production to the point that it’s almost completing one engine every 48 hours – equating to around 180 Raptors per year or a maximum cadence of one expendable three-engine Starship and 29-engine booster launch every nine weeks. At that run rate, Raptor has likely beat out Falcon’s venerable Merlin to become SpaceX’s most-produced rocket engine.
According to NASASpaceflight, SpaceX has already begun work on Raptors with serial numbers in the 150s. Two new Raptor test stands in work at its McGregor development facilities will also reportedly enable an average of one engine qualification every day – enough testing capacity to outfit 6 boosters and 30 Starships (~365 Raptors) per year. In short, SpaceX is well on its way to having the ability to manufacture and power a truly vast fleet of Starships and Super Heavy boosters.
The Tesla Semi was spotted mounted with ground truth validation equipment as the company nears its looming launch. The Semi is Tesla’s Class 8 all-electric truck, and has been utilized in its earlier stages by many companies like PepsiCo. and Frito-Lay, who have been using it in a pilot program.
The Semi was spotted in Sunnyvale, California, and sports a typical ground truth validation unit that Tesla routinely uses on its vehicles. Ground truth validation is essentially the process of training supervised algorithms to ensure they can perform reliably. Tesla typically performs this on vehicles that are being released soon:
Spotted the new semi adorned with ground truthing equipment. Haven’t seen anyone post this so figured I’d share.

The Semi being spotted with this type of validation rig is important because it means the company is working on solidifying a Full Self-Driving model for its commercial vehicle offering. This would be a massive development for not only Tesla but also the logistics industry as a whole.
There are strict regulations on driving hours for commercial truck drivers, and autonomy is a way to potentially combat these issues. FSD is already a widely effective way that owners of typical passenger vehicles take stress out of travel. Even launching a semi-autonomous platform for truck drivers to use to increase safety, reduce fatigue, and increase productivity would be a huge development.

The Semi has already proven to be an ideal solution for companies that use commercial logistics. It has increased efficiency and reduced operating costs for many companies that have been able to use it in pilot programs.
There are expected to be some bumps along the way. Tesla saw some challenges with FSD on the Cybertruck, as it had never had a vehicle with cameras at that height, so some of the features with FSD were not immediately available. Just a week ago, Tesla launched Actually Smart Summon (ASS) for Cybertruck, nearly three years after the vehicle was first delivered to customers.
President Donald Trump unveiled an upgraded Boeing 747-8 at Joint Base Andrews on June 19, 2026, describing the Qatar-gifted aircraft as an interim Air Force One equipped with advanced communications systems, including Starlink, Elon Musk’s SpaceX satellite internet service.
The plane, valued at around $400 million and modified for presidential use, serves as a bridge until the delayed VC-25B replacements arrive. Trump highlighted its luxury features and new technology during remarks to service members.
Trump stated:
“We have communication equipment up there that nobody’s ever seen before. It’s the highest level and, uh, including Starlink. My friend Elon is going to be very happy, but, uh, Starlink and we have, uh, four or five different sets of double and triple communications like people haven’t seen.”
He added:
“And it represents what can happen with hard work, innovation, and aggressive timelines because we did this quickly and yet there’s never been communication like is on this plane.”

The aircraft features a redesigned red, white, and blue livery and has been outfitted with Starlink satellite connectivity alongside other secure systems.
Trump praised the plane’s uniqueness, calling it among the world’s most luxurious. The gift from Qatar and subsequent modifications have drawn attention, with the jet positioned as a solution for presidential travel. It is expected to support operations, including potential ceremonial roles such as Fourth of July flyovers.
The event marked the formal introduction of the converted jet, which will help maintain capabilities while the primary Air Force One fleet undergoes modernization. Defense observers note the inclusion of commercial satellite technology like Starlink as part of efforts to ensure resilient communications, crucial to keep the country running as the President is in the sky.
President Trump’s comments underscored appreciation for rapid upgrades and innovation in equipping the aircraft. The plane remains a U.S. government asset and is slated for eventual transfer related to presidential library purposes after its service.
Tesla just gave what is perhaps its biggest signal yet that the launch of the Cybercab, its autonomous ride-hailing-geared car, is imminent.
The Cybercab has been spotted outside of Gigafactory Texas in massive numbers over the past few days, with hundreds of units being stored on property just days after the vehicle received a Certificate of Conformity from the EPA.
Today, things were a bit different.
Cybercabs spotted on Giga Texas property today had an addition: a Cybercab decal on the side, reminiscent of the “Robotaxi” ones that were placed on Model Ys just as the company launched its ride-sharing platform about a year ago.
Giga Texas drone operator Joe Tegtmeyer noticed the change today:

Tesla could be signaling that the Cybercab is preparing to enter the Robotaxi fleet in the coming weeks or months with this move. It seems more symbolic than anything; Tesla is ready to throw Cybercabs in the ride-hailing platform just as it did with Model Ys last year.
The addition of the Certificate of Conformity awarded to the Cybercab is another major factor working to Tesla’s advantage. The company now has permission from the EPA to allow the vehicle to operate on public roads and enter the chain of commerce. It’s officially street legal.

The big question that remains is whether Tesla will be able to operate the car without a safety monitor, especially considering it plans to put the car out there without a steering wheel or pedals. With the Cybercab only having a seating capacity of two, it is hard to believe Tesla will even consider putting a Safety Monitor in the car.
It did recently self-certify as Level 4 and has the ability to operate driverless vehicles in the State of Texas under a law that took effect on May 28. You can read more about that here:
Tesla’s Robotaxi dreams just took a massive step toward reality
We’d imagine Cybercabs will be on the roads as soon as July, but August will likely be a better estimate of when the car will be entered into the Cybercab fleet. It all depends at where Tesla is, as they’ve truly prioritized safety with the rollout of the Robotaxi platform.
