SpaceX’s Starship factory is churning out steel rockets faster than ever
SpaceX’s South Texas Starship factory is churning out steel rocket hardware faster than ever before according to photos of yet another prototype already in the works.
At the same time as SpaceX works around the clock to test SN4 and prepare the ship for what will be the first flight of a full-scale Starship prototype, the company is building not one; not two; but three additional prototypes. A confirmation that a third Starship was being simultaneously manufactured in South Texas came on May 25th when local Boca Chica resident and observer Mary (bocachicagal) captured a photo of a pair of stacked steel rings rather conspicuously labeled “SN7”.
While it’s possible that “SN7” is just a coincidence, it’s far more likely that it refers to Starship serial number 7 (SN7), set to be the seventh full-scale prototype built by SpaceX. The apparent start of SN7’s steel ring assembly process some two weeks ago also suggests that no less than several other rings are likely being mated in one or more of SpaceX’s three main manufacturing tents or a much taller windbreak structure. In fact, SpaceX is building Starship prototypes so quickly that the company is actively assembling a second launch mount, suggesting that two Starships could soon be tested more or less simultaneously without stepping on each other’s steel toes.
The most impressive aspect of SN7’s appearance, however, is the fact that SpaceX is already in the late stages of stacking Starship SN5 and begun preparing to stack Starship SN6 directly beside it just a few days ago. Based on labels attached to the side of a new steel nosecone section rolled out of SpaceX’s tent factory a few days ago, Starship SN5 will likely become the first full-scale Starship to reach its full height in a permanent, functional fashion. Back in October 2019, SpaceX did technically stack Starship Mk1 to its full height for a few weeks, but the ship’s nose section was never permanently attached and really only served as a pathfinder and full-scale mockup.
Starship Mk1 ultimately failed prematurely during its first major cryogenic pressure test in November 2019, bursting well before it reached the tank pressures needed for low-velocity hop tests (let alone orbital flight). In the sixth months since, SpaceX refocused its resources and spent much of the time dramatically upgrading its South Texas Starship production facilities and methods. In a rapid-fire series of tests of custom-built Starship tanks, SpaceX quickly proved that those improved methods could produce steel tanks more than capable of surviving pressures of ~8.5 bar (~125 psi) and beyond.
More recently, Starship SN4 – a full-scale prototype with two propellant tanks and three tank domes – passed a ~7.5 bar (~110 psi) cryogenic pressure test with flying colors, just shy of fully validating the smaller tank tests that made it possible. According to CEO Elon Musk, ~8.5 bar is enough to perform orbital launches with the ~40% safety margin preferred for human spaceflight, while 7.5 bar meets the minimum needed for Starship to perform uncrewed orbital launches with a ~25% safety margin.
In other words, SpaceX isn’t simply churning out low-fidelity prototypes – the ships that are being mass-produced are of a high enough quality to be qualified for orbital-class launches. Of course, the physical structure of Starship is just one of many technologies that need to work in harmony for successful orbital flights, many of which need to pass their own challenging tests to be declared ready for launch, but it’s still undeniably impressive that SpaceX is already building complete Starship fuselages in a matter of weeks.
In fact, given that Starship SN4 could perform the first hop test and that SN5 could be assigned to the first high-altitude (3-20+ km) flight tests, there is definitely a chance, however minimal, that Starship SN6 or SN7 could eventually be upgraded for the system’s inaugural orbital launch attempt. Regardless, it’s safe to say that the next several weeks are going to be jam-packed with numerous Starship production and test milestones.

SpaceX just launched a secret payload from California
SpaceX launched a classified Space Force mission from Vandenberg, revealing almost nothing about its payload.
SpaceX launched a classified Falcon 9 mission for the U.S. Space Force from Vandenberg Space Force Base on Saturday night, and the government released almost nothing about what was on board. The mission, designated USSF-366, lifted off from Space Launch Complex 4E with a window that opened at 9:52 p.m. ET and ran into the early hours of Sunday, according to SpaceX’s own mission page, which described the payload only as classified. SpaceX confirmed the launch on its X account and pointed viewers to a livestream that began roughly ten minutes before liftoff.

The lack of detail did not stop analysts from filling in the blanks. Independent tracking of the rocket’s stage drop zones matched the pattern SpaceX has used on previous Starlink Group 15 missions, according to reporting from Outer Space Today, which pointed to Starshield as the likely payload rather than a one off government satellite. Starshield is SpaceX’s national security product, a version of the Starlink satellite bus built to Pentagon specifications for earth observation, communications and hosted payloads. Unlike consumer Starlink, government agencies do not have to disclose what Starshield satellites are actually doing once they reach orbit.
USSF-366 is the latest entry in a steady flow of classified and semi classified work between SpaceX and the Space Force. The company picked up a $178.5 million task order in April to launch missile tracking satellites for the Space Development Agency, as Teslarati reported at the time, and followed that in July with a $1.6 billion award covering 18 more Falcon 9 missions from Vandenberg through the end of 2027, also detailed by Teslarati. Add those contracts up and SpaceX’s Pentagon business for 2026 alone tops $8 billion.

The Falcon 9 that flew Saturday landed back near the launch site, producing the sonic booms that have become routine for residents near Vandenberg. What is less routine is how little the public will likely ever learn about what the rocket carried. SpaceX and the Space Force have not confirmed the Starshield connection, and government satellite programs built on commercial buses rarely get identified beyond a mission number and a general orbit. For a company that live streams almost everything else it does, from Starship test flights to Optimus robot demos, USSF-366 is a reminder that some of SpaceX’s busiest work now happens entirely out of public view.
On Friday, Tesla launched the Outlet Adapter that enabled Vehicle-to-Load (V2L) energy transfer, meaning owners could essentially utilize their cars as a power source for things like laptops, electric grills, or string lights.
However, even owners of some of the newest builds of the Model Y are finding out that their cars are not compatible with the new $80 accessory, stirring up a new complaint among members of the community.
Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.
Upon the release of the Outlet Adapter on Friday, I signed into my Tesla account to order the accessory. However, I was met with the dreaded “This product is not compatible with your 2026 Model Y” message at the bottom of the screen.
Some said their accounts also displayed the same message, but they ordered anyway. However, they might be surprised to find that this is no mistake; some of the newest Model Ys do not have the appropriate Power Conversion System (PCS). Mine, which was ordered on this day last year and delivered on August 31, has the old 48A, single-phase PCS.
Vehicles with the new, two-piece PCS are able to utilize V2L features on their cars:
🚨 Looks like you can hit the Parts Catalog and enter your VIN and check to see if your Model Y will be able to use the adapter for V2L.https://t.co/QA9zRk7n2k
h/t to @SawyerMerritt for finding this out.
I am sad but this isn’t a huge loss. https://t.co/AYpI12QVV9 pic.twitter.com/LRFSrtRywo

Obviously, it’s disappointing. Many owners have taken delivery this year and still can not utilize the Outlet Adapter because their cars feature the old PCS:

It looks like if you have one of these older PCS units, you can upgrade, but the parts alone are $1,750, and that’s before Tesla adds labor for installing. It is honestly more logical to get some kind of portable power supply or power station at that point.
It is great that Tesla has enabled V2L for Model Y vehicles, but it is also unfortunate that vehicles that are less than one year old are not able to take advantage of this awesome new feature.
With that being said, it truly is a first-world problem; can you really complain when Full Self-Driving is available, maintenance is incredibly inexpensive, and the car has been so good through a year of ownership?
Tesla has launched a new Vehicle-to-Load (V2L) Outlet Adapter for Premium Model Y vehicles in the United States, meaning you can now power devices like laptops or light strings with your vehicle’s battery.
It appears the capability will be available for any Model Y Premium trim, including those that were purchased prior to the Adapter being launched. It will also only impact Juniper Model Y vehicles, so the first-gen owners will unfortunately not have access to this capability.
If your Model Y was purchased before Tesla renamed the trim levels to “Premium” and “Standard,” it does not seem to be compatible. My Model Y is technically a Premium build, as it is the Long Range All-Wheel-Drive. However, Tesla says it is not compatible with my vehicle.
🚨 Tesla has launched the Outlet Adapter for Model Y Premium in the U.S., enabling V2L capability for all Premium trims (that’s what it appears to be as it is available for purchase with all Premium trims)
It’s available for $80. 2.4kW max power and rated for 120v, 20A pic.twitter.com/lDxlVIk5s8

For $80, you can now utilize your car as a portable charger for small appliances or devices. This is perfect for things like tailgates, concerts, or camping, as you can now plug in devices that you might use. Those string lights for camping? That laptop for the other games that are on at the tailgate?
They’ll both utilize energy from your Tesla’s battery to be powered. This is the first time Tesla has expanded the capability to vehicles outside of the Model Y Performance and Cybertruck. However, this feature has been highly requested by owners for an extended period of time.
Tesla launched the Outlet Adapter in China last year:
Tesla China rolls out Model Y L V2L adapter, and it’s free for early owners
You will need the Mobile Connector to operate the Outlet Adapter: the Outlet Adapter will plug into the main housing of the Mobile Connector, where the appropriate adapter to charge your vehicle will plug in.
It is rated for 120 volts and 20 amps, and has a max power rating of 2.4kW.
You can buy it here from Tesla for $80.
