SpaceX blows up Starship tank to test new metal alloy
SpaceX has destroyed the third Starship ‘test tank’ prototype since it began building and testing the stout steel structures earlier this year.
Much like the third test tank SpaceX built was fashioned out of in-work hardware originally destined to become the full-scale Starship SN2 prototype, the latest tank was built with parts that may have initially been meant for Starship SN7. While SN7’s purpose – stress-testing new designs and manufacturing techniques – was largely identical to its predecessors, the test tank was by far the most radical departure from past hardware yet. The reason: SN7 was built entirely out of a different stainless steel alloy.
Deemed 304L, the type of steel is still readily available off the shelf and only 10-20% more expensive than the 301 alloy SpaceX has used to build all Starship prototypes up to SN7. The biggest change it brings to the table is improved ductility (malleability), particularly at the cryogenic temperatures Starship’s tanks will often be held at. By reducing brittleness, Starships built out of 304L steel should be able to fail far more gracefully by developing stable leaks instead of violently decompressing. In fact, the very same test tank destroyed on June 23rd demonstrated that capability perfectly when it sprung a leak during its first pressure test on June 15th.
During its first cryogenic pressure test with liquid nitrogen, SpaceX CEO Elon Musk revealed that the SN7 test tank managed to reach 7.6 bar (~110 psi) before it began to leak – technically satisfactory for orbital Starship launches with an industry-standard 25% safety factor. Thanks to the general flexibility of steel, including the new 304L alloy SN7 was built with, SpaceX was able to simply repair the leak it identified, readying the test tank for a second cryogenic pressure test barely a week later.

The tank’s second test was all but identical to the first up to the end, where its lower dome appeared to more or less unzip from the steel ring it was welded to. It remains to be seen if SN7 was able to beat its previous record during the second test but the failure mode was quite a bit different from any previous test tank, meaning that SpaceX has gathered useful new data regardless. If the 304L steel tank matched or beat a 301 tank’s current record of ~8.5 bar (~125 psi), SpaceX will very likely build all future Starship tanks out of the material.
According to Musk, another 304L test tank is already in the works and should be able to take SN7’s place very shortly. At the same time, SpaceX appears to finally be ready to roll the next full-scale Starship prototype (SN5) to the launch pad as early as June 24th to kick off cryogenic proof testing, Raptor static fires, and (hopefully) flight tests.

Tesla Model Y charges to bring strongest month in Australia in 2025
Tesla saw a strong month of sales in Australia, led by the dominating performance of the Model Y.

Tesla can thank the Model Y for bringing the company to its strongest monthly performance of the year in Australia.
In May, the Model Y accounted for 3,580 of the 3,897 total sales Tesla reported for the month in Australia. That’s a 9.3 percent increase from May 2024, while the Model Y had its best month since June 2024 with a 122.5 percent increase from the same month a year prior.
Additionally, it was the company’s best May in two years, when it sold 4,476 cars in May 2023.
It is a strong point in what has been a tough year for Tesla, but the difficulty can mostly be attributed to the switchover of production lines the company performed at each of its global production facilities.
It updated the Model Y earlier this year with a brand new front and rear fascia, as well as suspension improvements, and cabin modifications to provide a more comfortable ride.
Tesla’s Country Manager for Australia, Thom Drew, spoke to Drive in April about the Model Y and its influence on the company’s performance in Australia.
Tesla Cybertruck needs changes before Australia entry, but no guarantees it will arrive
He said the company saw tremendous interest in the Launch Edition of the new Model Y, which featured premium badging and some other novelty improvements compared to the Long Range All-Wheel-Drive that is available already.
Drew said:
“When we launched orders back in January, we had an enormous response to the launch edition. We’ve only just started test drives in the last couple of weeks. The boat’s been slowly making its way around the country. And now we’re seeing that kind of second wave come through, and seeing a lot of interest. I think we had a record test drive week, last week, in our entire history. So yeah, [we’re] seeing some really strong interest.”
Tesla is hoping to see improvements in sales performance across the globe, but it is primarily focused on the rollout of the Robotaxi platform, which is set for release on June 12.

Elon Musk explains Tesla’s domestic battery strategy
Elon Musk responded to a new note from an analyst that highlighted Tesla’s battery strategy.

Tesla CEO Elon Musk explained the automaker’s strategy for building batteries from top to bottom in a domestic setting as the company continues to alleviate its reliance on Chinese materials, something other companies are too dependent on.
With the Trump Administration, it is no secret that the prioritization of U.S.-built products, including sourcing most of the materials from American companies, is at the forefront of its strategy.
The goal is to become less dependent on foreign products, which would, in theory, bolster the U.S. economy by creating more jobs and having less reliance on foreign markets, especially China, to manufacture the key parts of things like cars and tech.
In a note from Alexander Potter, an analyst for the firm Piper Sandler, Tesla’s strategy regarding batteries specifically is broken down.
Potter says Tesla is “the only car company that is trying to source batteries, at scale, without relying on China.”
He continues:
“Eventually, Tesla will be making its own cathode active materials, refining its own lithium, building its own anodes, coating its own electrodes, assembling its own cells, and selling its own cars; No other US company can make similar claims.”
Musk, who spent time within the Trump White House through his work with the Department of Government Efficiency (DOGE), said that Tesla is doing the “important” work of localizing supply chains as the risks that come with being too dependent on foreign entities could be detrimental to a company, especially one that utilizes many parts and supplies that are manufactured mostly in China.
It is important, albeit extremely hard work, to localize supply chains to mitigate geopolitical risk
— Elon Musk (@elonmusk) June 3, 2025
Tesla has done a lot of work to source and even manufacture its own batteries within the United States, a project that has been in progress for several years but will pay dividends in the end.
According to a 2023 Nikkei analysis, Tesla’s battery material suppliers were dominated by Chinese companies. At the time, a whopping 39 percent of the company’s cell materials came from Chinese companies.
This number is decreasing as it operates its own in-house cell and material production projects, like its lithium refinery in Texas.
It also wants to utilize battery manufacturers that have plans to build cells in the U.S.
Panasonic, for example, is building a facility in Kansas that will help Tesla utilize domestically-manufactured cells for its cars.

Tesla stock: Morgan Stanley says eVTOL is calling Elon Musk for new chapter
Could Tesla dive into the eVTOL market? Morgan Stanley takes a look.

Tesla shares are up nearly 20 percent in the past month, but that is not stopping the only trillion-dollar automaker from attracting all types of new potential sectors to disrupt, at least from an investor and analyst perspective.
Morgan Stanley’s Adam Jonas is not one to shy away from some ideas that many investors would consider far-fetched. In a recent note, Jonas brought up some interesting discussion regarding Tesla’s potential in the eVTOL industry, and how he believes CEO Elon Musk’s answer was not convincing enough to put it off altogether.
Tesla’s Elon Musk says electric planes would be ‘fun problem to work on’
Musk said that Tesla was “stretched pretty thin” when a question regarding a plane being developed came up. Jonas said:
“In our opinion, that’s a decidedly different type of answer. Is Tesla an aviation/defense-tech company in auto/consumer clothing?”
Musk has been pretty clear about things that Tesla won’t do. Although he has not unequivocally denied aviation equipment, including planes and drones, as he has with things like motorcycles, it does not seem like something that is on Musk’s mind.
Instead, he has focused the vast majority of his time at Tesla on vehicle autonomy, AI, and robotics, things he sees as the future.
Tesla and China, Robotics, Pricing
Morgan Stanley’s note also discussed Tesla’s prowess in its various areas of expertise, how it will keep up with Chinese competitors, as there are several, and the race for affordable EVs in the country.
Tesla is the U.S.’s key to keeping up with China
“In our view, Tesla’s expertise in manufacturing, data collection, robotics/ physical AI, energy, supply chain, and infrastructure are more critical than ever before to put the US on an even footing with China in embodied AI,” Jonas writes.
It is no secret that Tesla is the leader in revolutionizing things. To generalize, the company has truly dipped its finger in all the various pies, but it is also looked at as a leader in tech, which is where Chinese companies truly have an advantage.
Robotics and the ‘Humanoid Olympics’
Jonas mentioned China’s recent showcasing of robots running half marathons and competing in combat sports as “gamification of robotic innovation.”
Tesla could be at the forefront of the effort to launch something similar, as the analyst predicts the U.S. version could be called “Humanoid Ninja Warrior.”
Pricing
Tesla is set to launch affordable models before the end of Q2, leaving this month for the company to release some details.
While the pricing of those models remains in limbo with the $7,500 tax credit likely disappearing at the end of 2024, companies in China have been able to tap incredibly aggressive pricing models. Jonas, for example, brings up the BYD Seagull, which is priced at just about $8,000.
Tesla can tap into an incredibly broader market if it can manage to bring pricing to even below $30,000, which is where many hope the affordable models end up.
During the Q3 2024 Earnings Call, Musk said that $30,000 is where it would be with the tax credit:
“Yeah. It will be like with incentive. So, 30K, which is kind of a key threshold.”
