SpaceX destacks “420” Starship, Super Heavy pair for the third time

Published

on

Update: Shortly before SpaceX CEO Elon Musk revealed that Super Heavy booster B4 and Starship S20 are no longer assigned to the rocket’s orbital launch debut, the company ‘destacked’ the pair for the third time.

Ship 20 was removed from Booster 4 on March 19th, two days before Musk’s tweets. That’s not unusual: it was actually Ship 20’s third removal from Super Heavy. However, almost as soon as the Starship was rolled out of the way, SpaceX began making visible preparations to also remove Super Heavy B4 from Starbase’s orbital launch mount. As of March 24th, the booster has been attached to a large crane for more than a day and a newly upgraded transport stand has been rolled into place beside the launch mount. It’s somewhat odd that the booster hasn’t already been removed but that step could happen at almost any moment, now – albeit likely in daylight.

Once both Ship 20 and Booster 4 have been removed, it’s hard to imagine that they will ever return to the orbital launch mount. In fact, at minimum, Super Heavy B4 will probably be retired almost immediately. Super Heavy B7 – a superior, refined, and upgraded prototype by almost every measure – is already almost fully assembled and could likely begin basic testing within a week or two.

SpaceX CEO Elon Musk says that Super Heavy Booster B4 and Starship S20 are no longer scheduled to support the first orbital-class test flight of the world’s largest rocket.

Rumors, signs, and reports of the significant change have been flowing among unofficial spaceflight communities for months. Booster 4 and Ship 20 were first confirmed by Elon Musk to be the pair assigned to Starship’s orbital test flight (OTF) in the summer of 2021. When the pair first rolled out to the launch pad in early August, Musk seemed confident that they could be ready for an orbital launch attempt within a month or two. The same was true in November 2021, when Musk stated that the same Starship and Super Heavy pair could be ready for their first launch as early as January or February 2022.

Musk’s latest update on Starship’s orbital test flight continues that schedule optimism but also introduces several major changes – changes that could easily take several months to fully work through.

Crucially, Musk revealed that the first Starship to attempt an orbital-class launch will now feature upgraded Raptor V2 engines – engines that require an entirely new thrust structure design. That already all but guaranteed that B4 and S20 had been overtaken but Musk also explicitly confirmed that they would be replaced with a new pair in a later tweet.

That new pair – widely assumed to be Super Heavy B7 and Starship S24 – feature a wide range of design changes, including substantially modified header tanks, an entirely new nosecone design, new layouts for secondary systems (pressurization, avionics, heat exchangers, etc.), and more. Most importantly, their thrust structures – giant ‘pucks’ machined out of steel – have been tweaked to support new Raptor V2 engines instead of the Raptor V1 and V1.5 engines that have been installed and tested on all Starship and Super Heavy prototypes to date.

Musk believes that SpaceX will be able to build (and presumably qualify) all 39 of the Raptors Ship 24 and Booster 7 will need before the end of April and fully install them – as well as all the heat shield components that must be fitted around them – by the end of May 2022. It’s unclear if the SpaceX CEO is accounting for the extensive proof testing Ship 24 and Booster 7 will likely need to complete before being qualified for flight, including cryogenic proof tests, wet dress rehearsals, and at least a few static fire tests.

In fact, SpaceX has only performed a single three-engine static fire test with a fully outdated Super Heavy prototype. Before the company is confident in its booster design, it’s practically a certainty that one or more prototypes will be put through a lengthy test campaign that gradually evolves from igniting a few engines to igniting all 29 or 33 Raptors. That may actually be one of the reasons SpaceX appears to be retiring Booster 4 without a single static fire or flight test – performing all the requisite work may have ultimately been perceived as a dead-end when every future Starship and Super Heavy prototype will feature a heavily redesigned engine.

This is to say that much like Musk’s last few Starship OTF schedule estimates, May 2022 also appears to be extremely optimistic. Booster 7 could potentially be ready for cryogenic proof testing any day now but Ship 24 is still in five large pieces and probably at least a month from any form of test readiness. Still, there are some reasons for optimism. If Booster 7 actually does start basic proof testing this month or early next without waiting for its Raptor engines or for heat shield installation, SpaceX could theoretically complete cryoproofing, begin installing one or a few new Raptors at a time, and iteratively progress from static firing a few to all 33 engines as the engines are arriving at Starbase.

At a minimum, even if that razor-sharp test schedule isn’t possible, Booster 7 would at least have a month or so of extra testing over Ship 24, minimizing the disproportionate amount of testing each prototype will likely need to be qualified for flight. Unlike Booster 4, Ship 20 has completed several static fires and cryoproofs without any apparent issue.

For now, SpaceX continues to prepare Ship 24 sections for stacking and appears to be buttoning up Booster 7, which could easily be ready to roll out for basic testing within a few weeks – and maybe sooner.

Tesla faces emission credits tax in Washington state

House Bill 2077 taxes emissions credits, mainly hitting Tesla. Lawmakers expect $100M/year from the taxes.

Washington state lawmakers are advancing a bill that would tax Tesla’s emission credits, targeting profits under the state’s clean vehicle policy. Lawmakers who support the bill clarify that the Tesla credit tax is unrelated to Elon Musk.

HB 2077, introduced in mid-April, seeks to impose a 2% tax on emission credit sales and a 10% tax on banked credits. The bill primarily affects Tesla due to exemptions for companies with fewer credits.

In 2022, Washington’s Department of Ecology mandated that all new cars sold by 2035 be electric, hydrogen-fueled, or hybrids, with 35% compliance required by next year. Carmakers selling more gas-powered vehicles can buy credits from companies like Tesla, which sells only electric vehicles.

A legislative fiscal analysis projects taxes on those credits would generate $78 million in the 2025-27 biennium and $100 million annually thereafter. About 70% of the taxes will be allocated to the state’s general funds, and the rest will help expand electric car infrastructure.

HB 2077 passed the state House eight days after its introduction and awaits a Senate Ways and Means Committee vote on Friday. At a House Finance Committee hearing, supporters, including union and social service advocates, argued the tax would prevent cuts to state services.

House Majority Leader Joe Fitzgibbon emphasized its necessity amid frozen federal EV infrastructure funds. “We didn’t have a budget crisis until this year. And we didn’t have the federal government revoking huge amounts of federal dollars for EV infrastructure,” he said.

Tesla’s lobbyist, Jeff Gombosky, countered that the proposal “runs counter to the intent” of the state’s zero-emission policy. Rivian’s lobbyist, Troy Nichols, noted a “modest” impact on his company but warned it could undermine the EV mandate. Kate White Tudor of the Natural Resources Defense Council expressed concerns, stating, “We worry it sets a dubious precedent.”

Fitzgibbon defended the tax, noting Tesla’s dominant credit stockpile makes it “one outlier” that is “very profitable.” “That’s the kind of thing legislators take an interest in,” he said. “Is it serving the interest of the public for this asset to be untaxed?”

With the legislative session nearing its end, the bill remains a key focus in budget talks in Washington.

Tesla Takedown group takes victory lap and aims for Starlink and SpaceX

Following Tesla’s Q1 2025 results, which were below expectations, the Tesla Takedown group celebrated.

The Tesla Takedown movement has taken a victory lap following the release of the electric vehicle maker’s first quarter 2025 earnings. With the group feeling encouraged by its results with the EV maker, Tesla Takedown is now setting its sights at Elon Musk’s other ventures, such as Starlink and SpaceX.

Because high-speed and reliable satellite internet for people in remote areas and the most affordable spaceflight provider for the United States need to be damaged, it seems.

Tesla Takedown’s Victory Lap

Following Tesla’s Q1 2025 results, which were below expectations, the Tesla Takedown group celebrated. “Today’s earnings report sends a very clear message. The Tesla Takedown grassroots pressure is beginning to hit Tesla where it hurts – the company’s bottom line,” the group noted.

Of course, the fact that Tesla did not sell its best-selling car for the majority of the first quarter due to the new Model Y changeover was conveniently left out by the group.

Nevertheless, in a comment to Insider, Tesla Takedown noted that its post-earnings email had an open rate of 53%, far above the 30% open rate of its previous emails. It also noted that it saw more than 30 new anti-Tesla protests added to its Action Network page within about 24 hours of the Q1 earnings’ release. Lastly, its BlueSky follower count rose by 10% to 15%, far above its weekly social media growth of 5%.

New Targets Acquired

Despite its name, Tesla Takedown is really more like an anti-Elon Musk group. Thus, it was no surprise that in a statement, the group noted that it is now setting its sights on Musk’s other ventures. As per Tesla Takedown, it is already making preparations for similar efforts against the CEO’s other ventures, such as SpaceX and Starlink. 

“Tesla Takedown has already started laying the groundwork to expand Tesla Takedown efforts to target other Musk businesses including SpaceX, Starlink, X and xAI,” the Tesla Takedown group noted.

Considering the absence of the Model Y in most of Q1 2025, Tesla Takedown’s alleged effects on the company and Elon Musk’s alleged brand damage could be determined more accurately this quarter. This Q2, after all, none of Tesla’s vehicles are paused, and the company seems determined to sell as many cars as possible.

Tesla is trying to make a statement with its Q2 delivery numbers

Tesla’s aggressive promotions for its vehicles today are quite strategic.

It is no secret that Tesla had subpar delivery numbers in the first quarter. It was due to a number of things, most of all the changeover to the new Model Y across its factories worldwide. The results, however, were enough for critics, both longtime and new, to declare that Tesla is just about done.

Looking at Tesla’s recently rolled out promotions across its lineup, however, it seems like the electric vehicle maker is dead serious about proving its skeptics wrong. 

Promotions, Promotions Everywhere

Just recently, Tesla announced that it was rolling out yet another free FSD transfer program for its customers. Such a program is designed to encourage longtime Tesla owners who may be holding onto their old vehicles with FSD to upgrade to a newer car. Tesla noted that its free FSD transfer is available for the Model S, X, 3, Y, and the Cybertruck in North America.

Tesla also announced a 0% APR financing program for new Model 3 orders in the United States. The Model 3 Performance even received an extra incentive, with the company offering premium paint colors such as Deep Blue Metallic and Pearl White for free with every vehicle purchase. Owners of Model Y classic units are also offered a $2,000 discount off the price of a new Model Y. Cybertruck customers, on the other hand, are offered special leasing rates.

Over in China, Tesla has announced a five-year, zero-interest financing program for the new Model Y. A similar program was also made available for the Model 3 sedan.

Taking Control of the “Demand Issue” Narrative

Tesla’s aggressive promotions for its vehicles today are quite strategic. The United States and China, after all, are two of the company’s largest markets. If Tesla wishes to post healthy delivery numbers this Q2, robust delivery numbers in the U.S. and China are practically required. 

When Tesla announced its earnings earlier this week, critics were overjoyed to see that the company had seen a notable drop in revenue. Arguments about the company’s demand issues were highlighted anew as well. It’s ironic, but just a few months after the Model Y secured its place as the world’s best-selling car by volume for the second year in a row, arguments about Tesla’s demand issues are abounding once more.

It remains to be seen if Tesla’s aggressive promotions this Q2 will make a difference in its vehicle sales worldwide. But if the company ends the second quarter with an impressive number of vehicle deliveries, it could take control of its demand narrative with authority. 

A Potential Elon Musk Point

A healthy delivery result for the second quarter may also renew faith among investors that CEO Elon Musk is indeed serious about leading Tesla to new heights. Over the past months, Musk’s attention had been evidently focused on his activities with the Trump administration’s Department of Government Efficiency (DOGE), but during the Q1 2025 earnings call, the CEO stated that he would be spending more time at Tesla starting May. 

This suggests that Musk would be extremely hands-on with the electric car maker for the majority of Q2 2025. Tesla is typically at its best when pushed by its aggressive CEO, so it would be interesting to see just how far the company could go before the end of June 2025.
