SpaceX CEO Elon Musk’s hat is safe after ULA Vulcan rocket launch slips to 2023
In the latest unfortunate development for SpaceX competitor United Launch Alliance’s next-generation Vulcan Centaur rocket, it looks like CEO Elon Musk may have been right all along when he forecast major delays more than three years ago.
In February 2018, even before SpaceX had flown Falcon Heavy for the first time, detractors with axes to grind were already busy attempting to downplay the rocket’s capabilities. On February 6th, Falcon Heavy lifted off for the first time, launching a several-ton Tesla Roadster car into interplanetary space and marking the first debut of a super heavy-lift rocket since the 1980s. That successful launch also meant that ULA’s last bastion of competitive advantage – the Delta IV Heavy rocket, fittingly by way of monopoly – was no longer alone.
Indeed, mere months after its near-flawless debut, Falcon Heavy had already secured its first operational US military launch contract. Delta IV Heavy, on the other hand, had already been preparing for retirement as part of ULA’s plan to replace two complex rockets (Delta and Atlas) with Vulcan.
Musk mercilessly took to task ULA’s heavy-lift rocket when commenters brought it up, noting that Falcon Heavy is largely comparable in a partially-reusable configuration but completely outclasses Delta IV Heavy – while still being dramatically cheaper – if all boosters are expended. The SpaceX CEO estimated that Delta IV Heavy launches would cost ULA significantly more than $400M after the company had effectively announced the end of Delta IV Medium production, though ULA CEO Tory Bruno still claimed a launch price of ~$350M.
In response to a reply noting that ULA’s plan was to replace Atlas V and Delta IV with Vulcan Centaur for launches “after 2020,” Musk pulled no punches, stating that he would “seriously eat [his] hat with a side of mustard if [Vulcan] flies a national security spacecraft before 2023.” At the time, ULA’s CEO did not exactly seem to share Musk’s shocking appraisal of the situation, which was out of left field even for major SpaceX proponents.
At the time, ULA’s party line touted Vulcan Centaur lifting off for the first time in late 2019 – the very next year. Ironically, weeks after Musk threw down his hat-eating gauntlet, ULA announced that Vulcan’s first launch had slipped to “mid-2020” – with a second flight later the same year – to give the company time to move straight to a larger upper stage originally meant to debut later on. Six months later, ULA announced yet another delay for Vulcan, this time pushing the rocket’s launch debut from mid-2020 to no earlier than (NET) April 2021.
Three years later, April 2021 has come and gone and ULA’s latest public Vulcan launch target is now “late 2021,” though that is all but guaranteed to slip into early 2022. In the latest (not-so-) shocking development for ULA’s next-generation rocket, the company has now requested and received permission from the US military to swap out Vulcan for an Atlas V rocket on what would have been the vehicle’s first military launch.
Exercising a contract loophole that had to have been explicitly designed to give ULA – and ULA alone – the option to fall back on its Atlas V or Delta IV rockets if Vulcan were to experience major delays, Atlas V will now take over the ULA’s USSF-51 mission. As a result, Vulcan Centaur’s first dedicated ‘national security’ launch is now officially scheduled no earlier than 2023, saving Elon Musk from having to eat his hat.
As of May 2021, ULA has now replaced one Vulcan launch with an Atlas V and inexplicably closed nine Atlas V launch contracts with Starlink competitor Amazon, bringing into question whether the company is ever actually going to simplify its rocket production lines. Given that ULA no longer appears to be planning on reusing parts of Vulcan, the only possible way Vulcan will end up more affordable than the rockets its replacing is if it quickly becomes the only rocket ULA produces, which was originally the plan. With ULA now apparently going out of its way to sell Atlas V commercially instead of Vulcan Centaur, it’s difficult to argue that the company has any interest at all in lowering the cost of access to space or offering SpaceX serious competition outside of lobbying and greasing the hinges of revolving doors.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
