SpaceX to put custom Starship propellant storage tanks through first trial

Published

In the latest twist in the saga of SpaceX’s custom-built Starship launch pad propellant storage tanks, the company appears to have retroactively decided to build small prototype meant solely for testing.

Known as a ‘test tank,’ the relatively small steel structure was fairly rapidly assembled from parts of an older Ground Support Equipment (GSE) tank scrapped in July over the last week or so. SpaceX completed the first Starship-derived propellant storage tank in April 2021 and rapidly rolled that tank (GSE1) and a second (GSE2) from the build site to the orbital launch pad just a few weeks apart. Less than a month after that, SpaceX also completed GSE tank #3, though things seemingly devolved into chaos immediately thereafter.

Only three months later would GSE3 finally be transported to – and installed on a concrete mount at – Starship’s first orbital launch site, and only after a number of structural modifications and in the footsteps of GSE tanks #5 and #6. Little is known about why SpaceX’s custom GSE tank production faltered so soon after it began, why none of the five Starship-sized tanks installed at the orbital pad have been fully plumbed or subjected to any kind of testing, or why structural modifications were seemingly required after the fact. However, it’s safe to say that SpaceX’s brand new GSE ‘test tank’ is now at the center of the mystery.

Thankfully, at minimum, the rapid appearance of SpaceX’s first GSE test tank returns some level of familiarity to the brief but chaotic history of Starship’s orbital launch pad propellant tanks. Test tanks are nothing new and have been an integral part of Starship development since Test Tank 1 first headed to SpaceX’s suborbital launch (and test) facilities in January 2020. In the 20 months since, SpaceX has built and tested seven small test tanks, several of which didn’t survive.

Whether intentionally destroyed or not, each test tank explicitly helped SpaceX qualify new manufacturing techniques, different materials, and different skin thickness and generally gather data more quickly and cheaply than full-scale prototypes would allow. Most recently, for example, SpaceX seemingly successfully tested a Super Heavy booster test tank, subjecting the prototype to cryogenic liquid nitrogen and using hydraulic rams to simulate the thrust of nine Raptor engines on an unproven disk-like thrust structure.

Now, almost as if SpaceX snapped out of a trance and remembered the utility of test tanks, the company has assembled a subscale GSE prototype presumably meant to verify that its custom-built propellant storage tanks can handle a set of conditions significantly different from the Starships they’re derived from. In this case, that GSE tank was quite literally built from scrapped sections of GSE tank #4. In fact, the top half (forward dome section) was quite literally cut off of GSE4 after the tank was scrapped last month for unknown reasons.

Over the last several months, while GSE tank production and installation took an unexpected hiatus, SpaceX workers slowly but surely welded steel rings (stiffeners) to the exterior of GSE1, GSE2, and GSE3. When GSE5 and GSE6 eventually headed to the pad, they left with those stiffeners already installed, implying that whatever tripped SpaceX up was likely structural. The GSE4 test tank also includes external stiffeners along each circumferential weld (where rings were stacked or domes joined).

At the same time as SpaceX was (or wasn’t, for several months) building its own GSE tanks, contractors normally tasked with assembling water towers and storage tanks in situ built eight massive 12m (~40 ft) wide tanks of their own. Deemed “cryo shells,” much like their name suggests, those tanks are meant to fully enclose SpaceX’s GSE tanks. SpaceX will use those shells to insulate their thin, single-walled steel propellant tanks, thus keeping their cryogenic contents cryogenic for as long as possible. How they’ll be insulated is unclear, though.

Based on the seemingly retroactive decision to strengthen the exterior of those GSE tanks, the general consensus as of late is that SpaceX wants to pull at least a partial vacuum in the gap between shell and tank. It’s also possible that SpaceX will do the opposite and pressurize that gap (as much as possible) with an insulative gas like nitrogen. Extra confusion comes from the fact that Starship tanks are technically designed to support a literal spacecraft (operating in a near-total vacuum) without the need for external stiffeners.

Additionally, it’s fairly clear that SpaceX hasn’t built a custom subscale cryoshell or concrete installation pad for its GSE4 test tank, meaning that it will really only be useful for testing some of the loads operational GSE tanks will experience inside their sleeves. Additionally, given that SpaceX has already completed six of the orbital pad’s seven GSE tanks and all seven of their cryosleeves, the discovery of any significant issues during GSE4 testing could easily trigger months of rework and delays. With any luck, though, GSE4 will sail through an imminent test campaign, clearing the way for SpaceX to finish plumbing, sleeving, and activating Starship’s first orbital launch site tank farm.

Tesla considers making a big move with Model Y pricing as demand is skyrocketing

“Trending toward a need to expedite output even further, which could mean adjusting pricing upward in the coming days. Trying hard not to, will see.”

Tesla is considering making a big move with Model Y pricing as demand is skyrocketing due to the EV tax credit expiring in just over a month.

With the $7,500 EV tax credit set to be removed on September 30, Tesla is experiencing increased demand for its Model 3 and Model Y. Customers are doing whatever they can to take delivery of the car they ordered as soon as possible.

The IRS recently adjusted the EV tax credit’s rules slightly.

Tesla set to win big after IRS adjusts EV tax credit rules

Previously, the vehicle had to be delivered by September 30, but a slight tweak the agency made last week will now allow customers to enter a legally binding contract along with a marginal down payment by that date. The delivery can occur after September 30, and the car can still qualify for the credit.

However, demand is getting so crazy for the Model Y that Tesla is considering a price increase on the all-electric crossover, as well as a potential boost in production output to keep up with orders.

Inventory is dwindling in several markets across the United States, a good sign for the company, as it could have one of its best quarters in recent history in terms of deliveries.

However, Tesla is thinking of bumping the price slightly, Raj Jegannathan, the company’s VP of IT, AI Infrastructure, Apps, Infosec, and Vehicle Service Operations, said on X:

The price adjustment would come as a response to increasing production output, Jegannathan’s response seems to indicate.

The bump would help Tesla’s margins, but the idea that the company could adjust pricing by increasing it would not be popular with potential car buyers. It might encourage some buyers to put their orders in sooner, hoping to avoid a new, higher price.

However, it could also steer some buyers away from putting an order in on a vehicle, especially if the price increase is more than a few hundred dollars.

Tesla boosted the price of the Model S, Model X, and Cybertruck recently, but brought in a “Luxe Package” to help justify it.

It comes with Free Full Self-Driving, Free lifetime Supercharging, four years of premium service, and lifetime Premium Connectivity.

Tesla produces 100,000th new Model Y in Giga Berlin

The milestone was announced on X.

Tesla has produced its 100,000th new Model Y at Gigafactory Berlin. The milestone was announced by the electric vehicle maker through its official Tesla Manufacturing account on social media platform X. 

New Tesla Model Y milestone

The milestone was announced by Tesla on X, when the company wrote “Today, we built the 100,000th New Model Y at Giga Berlin!” The announcement was accompanied by an image of a new Model Y coming off the line.

The milestone was received warmly by members of the Tesla community, many of whom expressed excitement at the further progress of the new Model Y program at Giga Berlin. The facility, after all, only produces Model Y units, which would make it the perfect site to produce new variants like the Model Y Performance and possibly even the Model Y L, which was recently launched in China. 

New Model Y ramp

As noted in a previous report from electrive, the initial production of the new Model Y started in Giga Berlin around mid-January 2025. Since the new Model Y involved a changeover from the legacy Y to the new variant, the ramp of the new Model Y’s production at the Germany-based facility was likely a gradual process over the past months. 

It would then be no surprise if the next 100,000 new Model Y units would be produced in Giga Berlin in a shorter period. Giga Berlin could become an even bigger factor in Tesla’s global sales, after all, especially if it becomes the site that produces the Model Y Performance and the Model Y L for Europe and other territories. Giga Berlin, if any, seems to be quite busy recently, with aerial videos of the facility showing a fleet of mysteriously covered Model Y units being stored within the complex.

Tesla set to win big after IRS adjusts EV tax credit rules

“For purposes of sections 25E, 30D, and 45W, a vehicle is ‘acquired’ as of the date a written binding contract is entered into and a payment has been made. A payment includes a nominal down payment or a vehicle trade-in.”

Tesla is set to potentially come out as a big winner as the IRS has adjusted the rules of the $7,500 EV tax credit slightly.

The $7,500 tax credit for electric vehicles is set to expire on September 30, but the IRS has made a slight adjustment to the terms of the credit that will give consumers a bit more time to buy an EV and receive the discount.

The original terms of the EV tax credit were that delivery of an EV must be completed by September 30. Even if you had made a reservation or put a down payment on an EV, if it did not arrive and take delivery by September 30, the credit would not apply to you.

Tesla is ready with a perfect counter to the end of US EV tax credits

This put some people in quite a tough situation. As wait times for some EVs, especially Tesla Model Y and Model 3 vehicles, continue to be pushed back due to an increase in demand as consumers are trying to take advantage of the credit, some car buyers ordered a car that was not the trim level, paint color, or interior color that they wanted.

However, the IRS has adjusted the terms of the tax credit to enable people to have a bit more time to get the vehicle they want.

Late last week, the agency said that the meaning of “acquired” has been changed, and now, if a consumer has entered a legally binding contract to take delivery of the vehicle, which includes a nominal down payment on the car, they can take delivery after the previous September 30 deadline and still qualify for the credit.

The IRS wrote:

“For purposes of sections 25E, 30D, and 45W, a vehicle is ‘acquired’ as of the date a written binding contract is entered into and a payment has been made. A payment includes a nominal down payment or a vehicle trade-in.”

Tesla could come out as a big winner here because of this. The company is experiencing a lot of demand for its cars because of the tax credit’s expiration, and now that the rule has been adjusted to include orders received by the 30th as long as they’re accompanied by a nominal down payment, some of these high-demand deliveries could leak into Q4.

Q3 is likely going to be a very strong quarter for Tesla, and questions remain about how the company will perform in subsequent quarters since the tax credit is going away. However, this slight adjustment is a big plus for Tesla and other EV makers.
