SpaceX is about to have a fleet of Starship rockets
SpaceX has finished the last major stacking event for the business half of its fifth full-scale Starship prototype, meaning that the company may be a week or less from having a fleet of Starships for the first time ever.
As of now, Starship serial number 5 (SN5) is on track to be completed in under a month, continuing a trend that SpaceX has managed over the entirety of 2020. Beginning in mid-January, SpaceX has completed several nosecone pathfinders, three test tanks, and three full-scale Starship prototypes – soon to be four once SN5 is finished. Once it is, however, SpaceX will be entering a new era of operations – fleet operations.
Up to this point, every full-scale Starship prototype and test tank SpaceX has built – excluding the tank SN2 was turned into in March – has been quickly destroyed over the course of one or two tests. For better or for worse, this has meant that SpaceX’s test and launch pad has always been more or less self-clearing, making way for the next prototype to roll out and begin testing after the scraps of its predecessor were removed. This time around, barring Starship SN4’s imminent demise, SpaceX will now have to deal with multiple completed Starship prototypes at the same time – a tiny taste of things to come.
For unknown reasons, SpaceX decided to swap out Starship SN4’s lone Raptor engine (likely SN18) after multiple wet dress rehearsals, partial engine tests, and two static fire tests – at least one of which was confirmed a success by CEO Elon Musk. Most recently, SpaceX removed Raptor SN18 to perform a more ambitious cryogenic pressure test, pushing Starship SN4’s propellant tanks all the way to 7.5 bar (~110 psi) at the same time as hydraulic rams simulated the thrust of three Raptor engines at the rocket’s base.
Instead of reinstalling Raptor SN18, SpaceX transported Raptor SN20 to the launch pad and installed it on Starship SN4 on May 10th, less than 24 hours after the prototype passed an orbital-class pressure test.
Aside from installing Raptor SN20, SpaceX teams have spent the last few days adding new COPVs (composite overwrapped pressure vessels) and plumbing to Starship SN4’s exterior – purpose largely unknown. While the new hardware is mostly a mystery, it is known that SpaceX is in the process of preparing SN4 and its new Raptor engine for a third wet dress rehearsal (WDR) and static fire test, necessary to ensure that Raptor SN20 is properly installed and functioning as expected.
Assuming that third static fire is successful, SpaceX’s will prepare Starship SN4 for its first flight, a ~150m (500 ft) hop test that will also be the first intentional flight of any full-scale Starship prototype since the program’s birth. For that hop test, SN4 will need some kind of attitude control system (ACS) thrusters to control its rotation and provide fine trajectory tuning to assist the ship’s lone Raptor engine. This is the likeliest explanation for the new hardware being installed on Starship SN4, as the ship does not currently appear to have ACS thrusters installed.
Starship Troopers
Of course, the first flight of a full-scale Starship prototype will probably be the riskiest test yet for the program and there’s a good chance that SN4 will meet its demise at some point during that flight. Enter Starship SN5.
As of May 12th, Starship SN5’s final two tank sections were stacked, effectively completing the most important half of the rocket (minus one final circumferential ring weld). SN5’s final outfitting of avionics and plumbing is still pending and will take at least a few days to a week or more, but that work can and has been completed after prototypes are transferred by road to the launch pad. Currently, Starship SN4 is occupying SpaceX’s one and only pad test stand, however, meaning that it wouldn’t make much sense to immediately move SN5 to the launch pad – at least until SN4 is done testing.
SN5 will also need a nose section and, perhaps, flaps installed, meaning that the full ship is likely still at least a week or two away from being finished, but that likely wont stop SpaceX from proof testing the rocket’s tanks if or when SN4 makes space at the launch pad.
According to comments made by Elon Musk, SN5 will likely become the first Starship prototype to have three Raptor engines installed and the first to attempt a truly high-altitude flight test if Starship SN4 is met with success in the coming weeks. As absurd as it feels to say, if SN5 completes triple-Raptor testing and a 20 km (~12 mi) flight test without issue, Musk has stated that the next step would be orbital flight tests. Starship SN6’s steel rings, meanwhile, are already being formed and stacked as SN5 nears completion.

Lemonade launches Tesla FSD insurance program in Oregon
The program was announced by Lemonade co-founder Shai Wininger on social media platform X.
Tesla drivers in Oregon can now receive significant insurance discounts when using FSD, following the launch of Lemonade’s new Autonomous Car insurance program.

Lemonade launches FSD-based insurance in Oregon
In a post on X, Wininger confirmed that Lemondade’s Autonomous Car insurance product for Tesla is now live in Oregon. The program allows eligible Tesla owners to receive roughly 50% off insurance costs for every mile driven using Tesla’s FSD system.
“And… we’re ON. @Lemonade_Inc’s Autonomous Car for @Tesla FSD is now live in Oregon. Tesla drivers in Oregon can now get ~50% off their Tesla FSD-driven miles + the best car insurance experience in the US, bar none,” Wininger wrote in his post.
As per Lemonade on its official website, the program is built on Tesla’s safety data, which indicates that miles driven using FSD are approximately twice as safe as those driven manually. As a result, Lemonade prices those miles at a lower rate. The insurer noted that as FSD continues to improve, associated discounts could increase over time.
How Lemonade tracks FSD miles
Lemonade’s FSD discount works through a direct integration with Tesla vehicles, enabled only with a driver’s explicit permission. Once connected, the system distinguishes between miles driven manually and those driven using FSD, applying the discount automatically to qualifying miles.
There is no minimum FSD usage requirement. Drivers who use FSD occasionally still receive discounted rates for those miles, while non-FSD miles are billed at competitive standard rates. Lemonade also emphasized that coverage and claims handling remain unchanged regardless of whether a vehicle is operating under manual control or FSD at the time of an incident.
The program is currently available only to Teslas equipped with Hardware 4 or newer, running firmware version 2025.44.25.5 or later. Lemonade also allows policyholders to bundle Tesla insurance with renters, homeowners, pet, or life insurance policies for additional savings.

Tesla exec: Preparations underway but no firm timeline yet for FSD rollout in China
The information was related by Tesla China Vice President Grace Tao in a comment to local media.
Tesla has not set a specific launch date for Full Self-Driving in China, despite the company’s ongoing preparations for a local FSD rollout.
The information was related by Tesla China Vice President Grace Tao in a comment to local media.
Tesla China prepares FSD infrastructure
Speaking in a recent media interview, the executive confirmed that Tesla has established a local training center in China to support the full adaptation of FSD to domestic driving conditions, as noted in a report from Sina News. However, she also noted that the company does not have a specific date when FSD will officially roll out in China.
“We have set up a local training center in China specifically to handle this adaptation,” Tao said. “Once officially released, it will demonstrate a level of performance that is no less than, and may even surpass, that of local drivers.”
Tao also emphasized the rapid accumulation of data by Tesla’s FSD system, with the executive highlighting that Full Self-Driving has now accumulated more than 7.5 billion miles of real-world driving data worldwide.
Possible 2026 rollout
The Tesla executive’s comments come amidst Elon Musk’s previous comments suggesting that regulatory approval in China could arrive sometime this 2026. During Tesla’s annual shareholder meeting in November 2025, Musk clarified that FSD had only received “partial approval” in China, though full authorization could potentially arrive around February or March 2026.
Musk reiterated that timeline at the World Economic Forum in Davos, when he stated that FSD approval in China could come as early as February.
Tesla’s latest FSD software, version 14, is already being tested in more advanced deployments in the United States. The company has also started the rollout of its fully unsupervised Robotaxis in Austin, Texas, which no longer feature safety monitors.

Tesla Semi lines up for $165M in California incentives ahead of mass production
The update was initially reported by The Los Angeles Times.
Tesla is reportedly positioned to receive roughly $165 million in California clean-truck incentives for its Semi.
The update was initially reported by The Los Angeles Times.
As per the Times, the Tesla Semi’s funding will come from California’s Hybrid and Zero-Emission Truck and Bus Incentive Project (HVIP), which was designed to accelerate the adoption of cleaner medium- and heavy-duty vehicles. Since its launch in 2009, the HVIP has distributed more than $1.6 billion to support zero-emission trucks and buses across the state.
In recent funding rounds, nearly 1,000 HVIP vouchers were provisionally reserved for the Tesla Semi, giving Tesla a far larger share of available funding than any other automaker. An analysis by the Times found that even after revisions to public data, Tesla still accounts for about $165 million in incentives. The next-largest recipient, Canadian bus manufacturer New Flyer, received roughly $68 million.
This is quite unsurprising, however, considering that the Tesla Semi does not have a lot of competition in the zero-emissions trucking segment.
To qualify for HVIP funding, vehicles must be approved by the California Air Resources Board and listed in the program catalog, as noted in an electrive report. When the Tesla Semi voucher applications were submitted, public certification records only showed eligibility for the 2024 model year, with later model years not yet listed.
State officials have stated that certification details often involve confidential business information and that funding will only be paid once vehicles are fully approved and delivered. Still, the first-come, first-served nature of HVIP means large voucher reservations can effectively crowd out competing electric trucks. Incentive amounts for the Semi reportedly ranged from about $84,000 to as much as $351,000 per vehicle after data adjustments.
Unveiled in 2017, the Tesla Semi has seen limited deliveries so far, though CEO Elon Musk has recently reiterated that the Class 8 all-electric truck will enter mass production this year.
