SpaceX’s fourth Starship prototype has begun to take shape in Florida
SpaceX’s Florida Starship team appears to have taken the first step towards assembling Starship Mk4, the fourth full-scale prototype of the next-generation spaceship.
Although SpaceX’s Boca Chica, Texas Starship campus is undeniably in the lead with their first prototype, Starship Mk1, it appears that the company’s Florida campus is far ahead of Texas with their second Starship prototype.
At the moment, SpaceX has set up two separate Starship build teams in Florida and Texas with the intention of creating a sort of internal competition to see which group’s Starships are first to flight and first to orbit. For the most part, it’s assumed that this “competition” is less a fight to the finish line than it is an A/B test, a common software development practice in which separate teams pursue different methods of achieving the same goals.
In the likely event that SpaceX is performing a radical form of A/B testing with rocket prototypes, both teams are continuously sharing best-practices and lessons-learned as they work to find the best possible methods for fabricating hardware and assembling Starships. Nevertheless, in A/B testing, fundamentally different approaches also tend to result in development schedules and final products that are unique, even if the end results are similar.
In the context of Starship, this is exactly what can be observed at SpaceX’s Florida and Texas facilities. Similarities abound in the radical method of en plein air manufacturing being implemented, while the Starship Mk1 and Mk2 hardware being built and assembled are also relatively similar, even if they have some distinct characteristics.
For example, it’s been observed that Starship Mk2 has almost certainly been constructed out of steel rings that are significantly taller than those used to assemble Starship Mk1. Taller rings meant that Mk2 needed fewer overall rings to reach the same height as Mk1, a fact that likely contributed to the impressive speed with which SpaceX’s Florida team was able to stack and weld most of Starship Mk2’s aerostructure.

According to SpaceX CEO Elon Musk, those similarities (and slight differences) are likely to continue for at least several more generations of prototypes. At a September 28th presentation and update on Starship, Musk revealed his opinion that Starship could be ready for its first orbital test flight(s) as few as six months from then – sometime in Q2 2020, give or take. To get there, Musk estimated that at least 5-6 Starship prototypes would need to be built in the interim.
Starship Mk3 will be built in Texas – in fact, the first ‘seamless’ steel ring may have already been fabricated at SpaceX’s Boca Chica facilities. According to Musk, Starship Mk4 will be SpaceX Cocoa’s second prototype. Based on John Winkopp’s October 17th drone overview, it appears that SpaceX’s Florida team has mounted the first steel Starship Mk4 ring atop a new work mount, potentially marking the start of Starship Mk4 assembly.
SpaceX’s Texas team has prepared at least one full-scale sample of a single-weld (‘seamless’) steel ring, perhaps the start of Mk1’s successor, Starship Mk3. Meanwhile, SpaceX Cocoa – seemingly at some kind of impasse with the final integration and assembly of Starship Mk2 – has churned out a huge number of similarly smooth steel rings, to the extent that Teslarati previously (and incorrectly) surmised that the first Super Heavy booster was being fabricated.
During Musk’s September 28th presentation, he effectively confirmed that the almost two-dozen steel rings hanging out on SpaceX’s Cocoa, Florida campus were almost certainly the beginnings of Starship Mk4. However, given the sheer number of rings present (23), the reality is that what could be the entirety of Starship Mk4’s cylindrical tank and thrust structure section is probably sitting outside in Florida, waiting to be stacked. Altogether, those 23 rings could reach a height of more than 40m (130 ft), potentially more than is actually needed for a Starship tank section.
Last but not least, local photographer and spaceflight fan Jon Van Horne captured what looks like a new Starship tank dome in work at SpaceX’s prospective Kennedy Space Center (KSC) build site, known as Roberts Rd. Given that Starship Mk2 already has two domes installed and a third and final dome staged and ready for installation, this fourth dome is very likely the first for Starship Mk4.
In short, SpaceX’s Florida team is probably weeks ahead of Boca Chica in the process of building a second full-scale Starship prototype. Of course, the ultimate winner of this mock competition isn’t Florida or Texas, it’s SpaceX’s Starship program as a whole.

Tesla Optimus’ pilot line will already have an incredible annual output
And this would just be the beginning. In the future, Musk mused that Optimus’ production could literally be out of this world.
During the 2025 Tesla Annual Shareholder Meeting, Elon Musk provided a teaser of the company’s targets for Optimus’s annual production. As per the CEO, Optimus’ pilot line will be capable of producing up to one million units annually.
And this would just be the beginning. In the future, Musk mused that Optimus’ production could literally be out of this world.
Musk targets world’s fastest production ramp for Optimus robots
Tesla’s first Optimus line will be built in Fremont, California, and is projected to produce around one million robots per year. Other facilities like Gigafactory Texas could scale Optimus production to 10 million units annually. Musk even joked that a 100-million-unit line might one day be built “on Mars.” With Optimus, Musk stated that Tesla is looking to achieve a historic production ramp.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one million unit production line in Fremont. And that’s Line One. And then a 10-million-unit-per-year production line here (at Giga Texas). I don’t know where we’re going to put the one hundred million unit production line, maybe on Mars. But I think it’s going to literally get to one hundred million a year, maybe even a billion a year,” Musk said.
Optimus and sustainable abundance
Tesla’s Master Plan Part IV is all about sustainable abundance, and Musk highlighted that the humanoid robot will play a huge role in his vision for the future. He noted that Optimus’ mass production could redefine economic and social systems worldwide and open up premium services for everyone across the globe.
“People often talk about eliminating poverty or giving everyone amazing medical care. There’s only one way to do that, and that’s with the Optimus robot,” Musk said. “With humanoid robots, you can actually give everyone amazing medical care. In terms of Optimus will be more precise. Optimus will ultimately be better than the best human surgeon with a level of precision that is beyond human… People always talked about eliminating poverty, but actually, Optimus will actually eliminate poverty,” Musk said.
Ford is considering a drastic move with its F-150 Lightning, which was the best-selling EV pickup on the market last quarter, beating out Tesla’s Cybertruck.
Ford has had a tumultuous entrance into its more expanded electric vehicle strategy over the past several years. At one point, the company was widely considered to be the most invested legacy automaker in the transition to electrification, but as the company has seen some real backtracking in terms of its sales and demand, it is cooling down its commitment.
At the end of Q3, it seemed to already be considering making some moves to cool off its EV ambitions, especially as the $7,500 EV tax credit was removed and it appeared that consumers would be less attracted to its vehicles without this sizeable discount.
Now, according to a new report from the Wall Street Journal, Ford is considering scrapping the F-150 Lightning altogether, as one employee said “the demand is just not there.”
Despite it being the best-selling EV pickup in the U.S. last quarter, the sales simply do not match up with the pricing, and financially, it is not the time to try to dive further into a project that is not making a profit. Ford has been dwindling in its commitment to EVs over the past several quarters, and its profits are reflecting a slowing interest in its electric vehicles.
Simply put, Ford’s combustion engine lineup of pickups in the F-Series is, by far, the best-selling division of trucks globally. Ford brought an awesome product forth with the Lightning, a mirror of the gas-powered F-Series that had a variety of trim levels for whatever the truck would be used for by the consumer.
However, the demand and sales have caused Ford to take a loss on its electric truck: figures from early last year indicated it was losing between $100,000 and $132,000 per vehicle.
It is not an official announcement, as Ford has not publicly said anything regarding its plans for the Lightning at this time.
Tesla has tentatively scheduled its unveiling event for the Roadster’s next-generation iteration, and you will not believe the date the company picked for it.
Tesla CEO Elon Musk said during the 2025 Annual Shareholders Meeting that the company is aiming for an April 1 demo event.
Yes, April Fools’ Day.

Tesla originally aimed for its “most epic demo” to take place at the end of this year. However, the writing on the wall as 2025 winds down seemed to indicate the company was not quite ready to show off everything it plans to implement into the Roadster.
Its capabilities have been teased quite heavily throughout most of the year, but the biggest hints came last week when Musk appeared on the Joe Rogan Experience Podcast.
He said:
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveil ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”
The Roadster has been somewhat of a letdown, at least in its newest version, thus far. Tesla has routinely delayed the project, putting those who put lofty down payments on the car in a weird limbo, lost at what to do.
One notable pre-orderer cancelled his reservation last week and got in a spat with Musk about it.
Now that there is a definitive date for the Roadster unveiling, Musk and Co. should have a more definitive cutoff date for features and capabilities. Chief Designer Franz von Holzhausen said earlier this year that when they showed Musk what they had done with the Roadster, the CEO encouraged them to do even more with it.
This delayed things further.
Musk also said he believes production would begin between 12 and 18 months after the unveiling, putting it out sometime in 2027.
