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.

The Cybercab is Tesla’s dedicated robotaxi, a gold-finished, two-passenger vehicle without a steering wheel or pedals, designed from the outset for unsupervised autonomous operation. It has been in limited Robotaxi service in Austin since September 2026, operating alongside Tesla’s larger fleet of Model Y vehicles.
Production takes place at Gigafactory Texas, which launched earlier this year. Tesla has stated for some time that it planned to put Cybercabs on sale by the end of the year, and it looks like they will come through on that promise if everything goes according to plan.
The Autonomy Subscription is mandatory for the vehicle to operate because it is void of a steering wheel and pedals. Tesla notes that the subscription and regular vehicle maintenance are required, indicating that personal owners will depend on the company’s software and service infrastructure rather than traditional ownership models.
One month of the subscription is included with purchase and subsequent months are billed separately until canceled.
This limited personal-sales opening marks a shift from Tesla’s earlier emphasis on fleet and transport-as-a-service operations. During the Q3 2026 Earnings Call, executives indicated that the vast majority of Cybercabs would remain Tesla-owned and used for rideshare service, while still aiming to place some vehicles with customers by year-end.
Elon Musk has previously targeted a price below $30,000, which was a huge point of emphasis for the Cybercab being the central point of Tesla’s “transportation-as-a-service” model.
Availability remains restricted to invited customers rather than a public order page, and the initial deliveries are expected only in the Austin area where unsupervised Robotaxi operations are already active. Buyers will need to accept the geographic and operational constraints of current autonomous deployment, as the vehicle cannot be driven manually outside supported zones.
The move gives a small number of early buyers the chance to own Tesla’s dedicated autonomous vehicle at the long-discussed sub-$30,000 price point, while the bulk of production continues to support the company’s expanding Robotaxi network.
UPDATE: The FAA has granted the license for Starship Flight 15.

SpaceX is set to attempt its 15th test flight of Starship this evening from Starbase, Texas.
SpaceX is targeting Starship Flight 15 for a launch as soon as today, Friday, November 13, pending an FAA Flight License, during a 75-minute window that opens at 4:45 p.m. CT (5:45 p.m. ET) from Orbital Launch Pad 2 at Starbase, Texas. The flight remains pending final regulatory approval.

The mission, using Booster 22 and Ship 42, aims to achieve the first full recovery of an orbital launch system. Primary objectives include a tower catch of the Super Heavy booster roughly six and a half minutes after liftoff and the first-ever tower catch of a Starship upper stage after more than 22 hours in space.
SpaceX will perform Starship double catch attempt with Flight 15
Between those catches, Ship 42 is planned to enter a low Earth orbit of about 275 km, complete roughly 14 orbits, and deploy 26 next-generation Starlink V3 satellites (Starlink Group 31-2). Three of those satellites carry cameras to inspect the ship’s heat shield in orbit and help controllers decide whether the vehicle is healthy enough for a return to the tower.
Contingency ocean splashdown options exist if either stage is not cleared for catch.
To watch the attempt, check the link to the broadcast in both X posts in this article. The live webcast is scheduled to begin about 30 minutes before liftoff and is planned to continue through the ship catch the next day, with the possibility of extended onboard views during the orbital coast via Starlink.
Because the schedule is dynamic, check back here or on our social media channels for the latest updates on window timing and regulatory status. A successful dual catch would mark a major milestone toward making Starship a rapidly reusable rocket capable of frequent flights.

Tesla has trimmed its Model Y offerings as its Standard All-Wheel-Drive configuration has been removed from the online configurator after roughly nine months on sale. The move follows the removal of the Cybertruck, as its trims have also been minimized as that vehicle heads for total discontinuation at the end of Summer 2027.
Launched in February 2026 as a mid-tier dual-motor option between the Rear-Wheel-Drive model and the Premium trims, the Standard All-Wheel-Drive Model Y offered 294 miles of range and a 4.6-second 0-60 mph time in a stripped-down package.
🚨 Tesla has pulled the $41,990 Model Y AWD from its U.S. configurator after nine months on sale.
The cheapest AWD Model Y you can order is now the $49,990 Premium AWD, with Premium deliveries quoted for Jan–Mar 2027.
The $39,990 RWD stays, and AWD units remain in inventory. https://t.co/uROJp2lVpx

With it gone, the cheapest new AWD Model Y buyers can configure is now the Premium AWD at $49,990, with estimated deliveries pushed into January–March 2027. The $39,990 rear-wheel-drive Model Y remains available for custom orders, and some AWD units are still listed in inventory.
The move arrives days after Tesla sharply narrowed its Cybertruck lineup. New orders for the Dual Motor AWD and Premium AWD versions have been disabled, leaving only the high-performance Cyberbeast—priced around $109,990 before fees—as the sole configurable option.
Elon Musk has stated that Cybertruck production at Gigafactory Texas will wind down around the middle to late summer of 2027 to free manufacturing space for greater Cybercab output. Tesla has raised prices on remaining trims and is prioritizing higher-margin builds while working through an existing order backlog that exceeds what the line can complete before conversion.
These parallel decisions reflect a broader effort to simplify Tesla’s retail customer lineup. Lower-volume or lower-margin variants are being phased out or deprioritized in favor of core, higher-spec models that generate stronger profitability and clearer production planning.
For the Model Y, this concentrates volume on the remaining RWD and Premium configurations while Premium deliveries already stretch into 2027. For the Cybertruck, it accelerates the transition away from a stainless-steel pickup that underperformed relative to initial volume expectations.
Tesla Model Y Standard Full Review: Is it worth the lower price?
The freed capacity and reduced complexity directly support Cybercab scaling. Tesla began pilot Cybercab production at Giga Texas in early 2026, launched paid autonomous rides in Austin in September, and is preparing for substantial volume growth.
By streamlining the existing vehicle portfolio, the company is reallocating factory space, engineering attention, and supply-chain resources toward its purpose-built Robotaxi, which lacks a steering wheel or pedals and is designed exclusively for unsupervised autonomy.
The result is a leaner retail lineup today and a clearer path to high-volume Cybercab deployment tomorrow.
