SpaceX’s reusable Falcon 9 fleet takes shape as rocket booster production ramps
Per a source involved in SpaceX’s cross-country rocket transport infrastructure, the company continues to beat the expectations of its closest followers, pointing towards an inflection point in the production and testing of new Falcon 9 Block 5 rocket boosters and upper stages.
Building off of a number of Falcon 9 booster, upper stage, and fairing spottings over the past six weeks, it can reasonably be concluded that SpaceX has completed, shipped, tested (i.e. static fires in Texas), and delivered (to launch sites) as many Falcon 9 rockets in six weeks as were shipped, tested, and launched in the preceding five months – perhaps even 30% more.
This extreme production ramp can be attributed almost entirely to the maturation of Falcon 9 Block 5’s design and manufacturing apparatus, owing to the fact that the rocket’s most recent (and theoretically final) upgrade necessitated significant changes to almost every major aspect of the Falcon family. Meanwhile, a considerable amount of time and effort had to be directed towards the optimization and production of the first Falcon Heavy, to some extent an entirely bespoke rocket built off of much older Falcon 9 cores and a center core design unlikely to be repeated.

With Falcon Heavy completed and launched in February and the last non-Block 5 booster built, launched, and relaunched in the last three months, Falcon 9 Block 5 has for the first time been allowed to become SpaceX’s near-singular focus for manufacturing and testing, both in the Hawthorne factory, the McGregor, TX testing facility, and SpaceX’s three launch pads.
This change in focus likely means that SpaceX was finally able to rid itself of what were effectively multiple SKUs (serial versions) of its workhorse rocket, presumably allowing their supplier and manufacturing apparatus to be significantly streamlined. With low-volume production and limited manufacturing space, multiple SKUs were likely a massive challenge for the Hawthorne factory and the McGregor testing facility, where the stand used to test Falcon 9 boosters likely required significant modifications to support Block 5 static fires. Meanwhile, SpaceX’s three launch pads in Florida and California all needed their own series of upgrades to transfer from Block 4 to Block 5.

Regardless, SpaceX has clearly gotten its manufacturing feet back under it and has ever-growing confidence in the nascent Block 5 iteration of Falcon 9. COO and President Gwynne Shotwell noted in a May 2018 CNBC interview that she believed the Hawthorne factory was nominally capable of producing one Merlin engine a day and two Block 5 boosters per month, and this recent burst of activity appears to heartily confirm her estimates. What remains to be seen is if what appears to be a six-week sprint (at least relative to the last year or so of rocket building) will instead prove to be the norm for the second half of 2018 and 2019.
If SpaceX can continue to sustain this extraordinarily rapid-fire pace of rocket production for just the next six months, the company could round out 2018 with a strong start to what Shotwell described would be a “sizable fleet” of Falcon boosters. Block 5 boosters B1047, B1048, and B1049 are now finished with static fire testing in McGregor after shipping from Hawthorne and either at launch sites or on their way, while B1050 most likely just arrived at McGregor for its own static fire. The first successfully launched and recovered Block 5 booster (B1046) was said by CEO Elon Musk to be undergoing a thorough teardown analysis – a process that almost certainly has been completed given the burst of Block 5 shipments and testing – and should be free to support additional launches later this year.
If SpaceX continues to produce nearly two boosters per month, the company could round out 2018 with a fleet of nearly 16 Falcon 9 boosters, each of which has been designed to support anywhere from a handful to a hundred reuses.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.
