US Air Force awards SpaceX $20m contract to support its biggest spy satellites
Slipping beneath the watchful eye of many skilled defense journalists, the government contracting database FPDS.gov indicates that the US Air Force awarded SpaceX more than $20 million in November 2017 to conduct a design study of vertical integration capabilities (VIC). Describing what exactly this means first requires some background.
Vertical whaaaat?
The flood of acronyms and technical terminology that often follow activities of the Federal government should not detract from the significance of this contract award. First and foremost, what exactly is “vertical integration” and why is significant for SpaceX? Not to be confused with more abstract descriptions of corporate organization (vertical integration describes one such style), integration here describes the literal process of attaching satellite and spacecraft payloads to the rockets tasked with ferrying them to orbit.
Likely as a result of its relative simplicity, SpaceX has used a system of horizontal integration for as long as they have been in the business of launching rockets, be it Falcon 1, Falcon 9, or Falcon Heavy. In order to integrate payloads to the rocket horizontally, SpaceX has a number of horizontal integration facilities (HIF) directly beside each of their three launch pads – two in Florida, one in California. After being transported from the company’s Hawthorne, CA rocket factory, Falcon 9 and Heavy boosters, second stages, payload fairings, and other miscellaneous components are all brought into a HIF, where they are craned off of their transporters (a semi-trailer in most cases) and placed on horizontal stands inside the building.

While in the HIF, all three main components are eventually attached together (integrated). The booster or first stage (S1) has its landing legs and grid fins installed soon after arrival at the launch site, followed by the mating of the first and second stages. Once these two primary components of the rocket are attached, the entire stack – as the mated vehicle is called – is once again lifted up by cranes inside the facility and placed atop what SpaceX calls the strongback (also known as the Transporter/Launcher/Erector, or TEL). A truly massive steel structure, the TEL is tasked with carrying the rocket to the launch pad, typically a short quarter mile trek from the integration facility. Once it reaches the pad, the TEL uses a powerful hydraulic lift system to rotate itself and its rocket payload from horizontal to vertical. It may look underwhelming, but it serves to remember that a complete Falcon 9/Heavy and its TEL are both considerably more than twice as tall as a basketball court is long.

Once at the pad, the TEL serves as the rocket’s connection to the pad’s many different ground systems. Crucially, it is tasked with loading the rocket with at least four different fuels, fluids, and gases at a broad range of temperatures, as well as holding the rocket down with giant clamps at its base, providing connection points to transmit a flood of data back to SpaceX launch control. SpaceX’s relatively unique TEL technology is to some extent the foundation of the company’s horizontal integration capabilities – such a practice would be impossible without reliable systems and methods that allow the rocket to be easily transported about and connected to pad systems.
Still, after the Amos-6 mishap in September 2016, which saw a customer’s payload entirely destroyed by a launch vehicle anomaly ahead of a static fire test, SpaceX has since changed their procedures, and now conducts those static fire tests with just the first and second stages – the payload is no longer attached until after the test is completed. For such a significant decrease in risk, the tradeoff of an additional day or so of work is minimal to SpaceX and its customers. Once completed, the rocket is brought horizontal and rolled back into the HIF, where the rocket’s payload fairing is finally attached to the vehicle while technicians ensure that the rocket is in good health after a routine test-ignition of its first stage engines.

Before being connected to the rocket, the payload itself must also go through its own integration process. Recently demonstrated by a flurry of SpaceX images of Falcon Heavy and its Roadster payload, this involves attaching the payload to a payload adapter, tasked with both securing the payload and fairing to the launch vehicle. Thankfully, the fairing is far smaller than the rocket itself, and this means it can be vertically integrated with the payload and adapter. The final act of joining and bolting together the two fairing halves is known as encapsulation – at which point the payload is now snug inside the fairing and ready for launch. Finally, the integrated payload and fairing are lifted up by cranes, rotated horizontally, and connected to the top of the rocket’s second stage, marking the completion of the integration process.
A different way to integrate
Here lies the point at which the Air Force’s $20m contract with SpaceX comes into play. As a result of certain (highly classified) aspects of some of the largest military satellites, the Department of Defense (DoD) and National Reconnaissance Office (NRO) prefer or sometimes outright require that their payloads remain vertical while being attached to a given rocket. The United Launch Alliance (ULA), SpaceX’s only competition for military launches, almost exclusively utilizes vertical integration for all of their launches, signified by the immense buildings (often themselves capable of rolling on tracks) present at their launch pads. SpaceX has no such capability, at present, and this means that they are effectively prevented from competing for certain military launch contracts – contracts that are often the most demanding and thus lucrative.
It’s clear that the Air Force itself is the main impetus pushing SpaceX to develop vertical integration capabilities, a reasonable continuation of the military’s general desire for assured access to orbit in the event of a vehicle failure grounding flights for the indefinite future. For example, if ULA or SpaceX were to suffer a failure and be forced to ground their rockets for months while investigating the incident, the DoD could choose to transfer time-sensitive payload(s) to the unaffected company for the time being. With vertical integration, this rationale could extend to all military satellites, not simply those that support horizontal integration.

Fittingly, the ability to vertically integrate satellites is likely a necessity if SpaceX hopes to derive the greatest possible value from its recently and successfully introduced Falcon Heavy rocket, a highly capable vehicle that the government is likely very interested in. Although the specific Air Force contract blandly labels it a “Design Study,” (FPDS.gov account required) its hefty $21 million award may well be far more money than SpaceX needs to design a solution. In fact, knowing SpaceX’s famous ability to develop and operate technologies with exceptional cost efficiency, it would not be shocking to discover that the intrepid launch company has accepted the design study grant and instead jumped head-first into prototyping, if not the construction of an operational solution. More likely than not, SpaceX would choose to take advantage of the fixed tower (known as the Fixed Service Structure, FSS) currently present at Pad 39A, atop which a crane and work platforms could presumably be attached
Intriguingly, it is a real possibility that Fairing 2.0 – its first launch scheduled to occur as early as Feb. 21 – could have been upgraded in part to support present and future needs of the Department of Defense, among numerous other benefits. Fairing 2.0’s larger size may have even been precipitated by physical requirements for competing for and dealing with the largest spysats operating by the DoD and NRO, although CEO Elon Musk’s characterization of that change as a “slightly larger diameter” could suggest otherwise. On the other hand, Musk’s offhand mention of the possibility of significantly lengthening the payload fairing is likely aimed directly at government customers in both the civil and military spheres of space utilization. Time will tell, and it certainly will not hurt SpaceX or its customers if Fairing 2.0 is also considerably easier to recover and reuse.
Under consideration. We’ve already stretched the upper stage once. Easiest part of the rocket to change. Fairing 2, flying soon, also has a slightly larger diameter. Could make fairing much longer if need be & will if BFR takes longer than expected.
— Elon Musk (@elonmusk) February 12, 2018
Ultimately, it should come as no surprise that SpaceX would attempt to leverage this contract and the DoD’s interest in ways that might also facilitate the development of the company’s futuristic BFR rocket, intended to eventually take humans to the Moon, Mars, and beyond. As shown by both 2016 and 2017 iterations of the vehicle, it appears that SpaceX intends to use vertical integration to attach the spaceship (BFS) to the booster (BFR). While it’s unlikely that this Air Force contract will result in the creation of a vertical integration system that could immediately be applied to or replicated for BFS testing, the experience SpaceX would gain in the process of building something similar for the Air Force would be invaluable and essentially kill two birds with one stone.
While now outdated, SpaceX’s 2016 Mars rocket featured a giant crane used for vertical integration. BFR appears to use the same approach. (SpaceX)

Tesla is bringing closure to its flagship Model S and Model X vehicles, which CEO Elon Musk said several years ago were only produced for “sentimental reasons.”
The Model S and Model X have been light contributors to Tesla’s delivery growth over the past few years, commonly contributing only a few percentage points toward the over 1.7 million cars the company has handed over to customers annually since 2022.
However, the Model S and Model X have remained in production because of their high-end performance and flagship status; they are truly two vehicles that are premium offerings and do not hold major weight toward Tesla’s future goals.
On Wednesday, during the Q4 2025 Earnings Call, Musk confirmed that Tesla would bring closure to the two models, ending their production and making way for the manufacturing efforts of the Optimus robot:
“It is time to bring the Model S and Model X programs to an end with an honorable discharge. It is time to bring the S/X programs to an end. It’s part of our overall shift to an autonomous future.”
Musk said the production lines that Tesla has for the Model S and Model X at the Fremont Factory in Northern California will be transitioned to Optimus production lines that will produce one million units per year.

Tesla will continue to service Model S and Model X vehicles, but it will officially stop deliveries of the cars in Q2, as inventory will be liquidated. When they’re gone, they’re gone.

Tesla has been making moves to sunset the two vehicles for the better part of one year. Last July, it stopped taking any custom orders for vehicles in Europe, essentially pushing the idea that the program was coming to a close soon.
Musk said back in 2019:
“I mean, they’re very expensive, made in low volume. To be totally frank, we’re continuing to make them more for sentimental reasons than anything else. They’re really of minor importance to the future.”
That point is more relevant than ever as Tesla is ending the production of the cars to make way for Optimus, which will likely be Tesla’s biggest product in the coming years.
Musk added during the Earnings Call on Wednesday that he believes Optimus will be a major needle-mover of the United States’ GDP, as it will increase productivity and enable universal high income for humans.

Earnings call updates
The following are live updates from Tesla’s Q4 and FY 2025 earnings call. I will be updating this article in real time, so please keep refreshing the page to view the latest updates on this story.
16:25 CT – Good day to everyone, and welcome to another Tesla earnings call live blog. There’s a lot to unpack from Tesla’s Q4 and FY 2025 update letter, so I’m pretty sure this earnings call will be quite interesting.
16:30 CT – The Q4 and FY 2025 earnings call officially starts. IR exec Travis Axelrod opens the call. Elon and other executives are present.
16:30 CT – Elon makes his opening statement and explains why Tesla changed its mission to “Amazing Abundance.” “With the continued growth of AI and robotics, I think we’re headed towards a future of universal high income,” Musk said, adding that along the way, Tesla will still be improving its products while keeping the environment safe and healthy.
16:34 CT – Elon noted that the first steps for this future are happening this year, thanks to Tesla’s autonomy and robotics programs, which will be launching and ramping this year. He also highlighted that Tesla will be making major investments this year, though the company will be very strategic when it comes to its funding. “I think it makes a ton of strategic sense,” Musk said.
16:36 CT – Elon also announces the end of the Model S and Model X programs “with an honorable discharge.” If you’re interested in buying a Model S or X, it’s best to do it now, Musk said. The Model S and Model X factory in Fremont will be replaced by an Optimus line. “It’s slightly sad, but it is time to bring the S and X program to an end. It’s part of our overall shift to an autonomous future,” Musk said.
16:38 CT – Elon discusses how Unsupervised FSD is now starting for the Robotaxi service. He noted that these Unsupervised Robotaxis don’t have any chase cars as of yesterday. He reiterated Tesla’s plans for owners to be able to add their own vehicles to the Robotaxi fleet. Autonomy target for the end of the year is about a quarter or half of the United States, Musk said.
16:41 CT – Elon noted that the Tesla Energy team is absolutely killing it. He also stated that Tesla expects its Energy business to continue growing, and that the “solar opportunity is underrated.”
16:43 CT –Elon also added that Tesla Optimus 3 will be unveiled in about three months, probably. The Model S and Model X line in Fremont will be a million-unit Optimus production line. Looks like Optimus is really coming out of the gate with large, meaningful volumes. “The normal S curve for manufacturing ramps is longer for Optimus,” Musk stated. “Long term, I think Optimus will have a significant impact on the US GDP.”
16:44 CT – Elon closes his opening statements with a sincere thanks to the Tesla team. He also noted that he feels fortunate to be able to work alongside such a talented workforce.
Elon ends his opening remarks with an optimistic prediction about the future.“The future is more exciting than you can imagine,” he concluded.
16:47 CT – Tesla CFO Vaibhav Taneja makes his opening remarks. He discusses several aspects of Tesla’s Q4 milestones. He noted that Tesla Energy achieved yet another gross profit record during the fourth quarter. There’s insane demand for the Megapack and Powerwall. Backlogs for these products are healthy this 2026. He also noted that Tesla ended 2025 with a bigger vehicle order backlog compared to recent years.
16:53 CT – Investor questions from Say begin. The first question is about Tesla’s expectations for the Robotaxi Network. Lars Moravy noted that it has the advantage of manufacturing and scale, and Tesla believes that the Robotaxi Network will significantly grow year over year. Elon highlighted that the Cybercab will be produced with no steering wheel or pedals. No fallback. Elon also noted that Tesla expects to produce more Cybercabs than all its other vehicles combined in the future.
16:51 CT – The next question is if Tesla still expects to launch new models, such as affordable cars. Lars Moravy noted that Tesla did release affordable variants last year, and Tesla is still pushing hard to lower its costs. That being said, Tesla is really pushing the Cybercab as its total addressable market is larger than consumer-owned cars. Lars also mentioned that Tesla will produce different vehicles for its Robotaxi services.
16:56 CT – Elon noted that eventually, Tesla will produce mostly autonomous cars. The exception would be the next-generation Roadster, which will be a true driver’s car.
17:03 CT – A question about Elon’s past comments about a potential next pickup truck was asked. Lars noted that the Cybertruck is still performing well in the electric pickup truck segment, though Tesla is known for flexibility. Elon added that Tesla will be transitioning the Cybertruck line to a fully autonomous vehicle line. He also stated that the Cybertruck is a useful vehicle. “An autonomous Cybertruck will be useful for that.”
17:10 CT – A question was asked about when FSD will be 100% Unsupervised. Elon noted that 100% Unsupervised FSD is already being used today, though only in the Austin Robotaxi program. Tesla is still being extremely careful with its rollout.
When asked about Tesla’s chip program, Elon noted that he feels pretty good about Tesla’s chip strategy. But in terms of selling Tesla’s chips outside Tesla, the company has to make sure it has enough chips for Optimus robots, data centers, and other programs first.
17:18 CT – Analyst questions begin. First up is Wolf Research. He asks about Tesla’s increasing Capex, specifically where the majority of it is going. The Tesla CFO noted that programs in six factories are going live this year, so that consumes Capex. The Optimus program also consumes a lot of resources. The growth of Tesla’s current capacity is also consuming a lot of resources. As for how these programs will be funded, the CFO pointed to Tesla’s massive war chest, as well as initiatives such as the Robotaxi Network.
17:21 CT – Morgan Stanley asks about Tesla’s xAI investment. The analyst asked about more information about how Tesla and xAI will work together. The CFO noted that this investment is part of Master Plan Part IV. Elon also mentioned some advantages for xAI’s technology for Tesla’s products, like Grok being used to manage a Robotaxi fleet or a group of Optimus robots.
17:24 CT – Barclays asks Elon about the constraints on memory. Does Tesla have any near term constraints for Tesla vehicles’ memory? Elon responded that the Tesla AI computer is already very compute and memory-efficient. The intelligence per gigabyte is important. Musk noted that Tesla is ahead of the industry by an order of magnitude or more.
17:29 CT – Cannacord asks about startups from China entering the humanoid market. What competitive advantage does Optimus have compared to these rivals? Elon stated that he believes China will be a key competitor in the humanoid robot market. China will be the toughest competitor for Tesla. That being said, Elon noted that Tesla believes Optimus will be ahead in real-world intelligence, electromechanical dexterity, and hand design.

Tesla announces massive investment into xAI
“On January 16, 2026, Tesla entered into an agreement to invest approximately $2 billion to acquire shares of Series E Preferred Stock of xAI as part of their recent publicly-disclosed financing round,” it said.
Tesla has announced a major development in its ventures outside of electric vehicles, as it confirmed today that it invested $2 billion into xAI on January 16.
The move is significant, as it marks the acquisition of shares of Series E Preferred Stock, executed on market terms alongside other investors. The company officially announced it in its Q4 2025 Shareholder Deck, which was released at market close on Wednesday.
The investment follows shareholder approval in 2025 for potential equity stakes in xAI and echoes SpaceX’s earlier $2 billion contribution to xAI’s $10 billion fundraising round.
Tesla said that, earlier this month, it entered an agreement to invest $2 billion to acquire shares of Series E Preferred Stock of xAI:

CEO Elon Musk, who is behind both companies, is now weaving what appears to be an even tighter ecosystem among his ventures, blending Tesla’s hardware prowess with xAI’s cutting-edge AI models, like Grok.
Tesla confirmed the investment in a statement in its Shareholder Deck:
“On January 16, 2026, Tesla entered into an agreement to invest approximately $2 billion to acquire shares of Series E Preferred Stock of xAI as part of their recent publicly-disclosed financing round. Tesla’s investment was made on market terms consistent with those previously agreed to by other investors in the financing round. As set forth in Master Plan Part IV, Tesla is building products and services that bring AI into the physical world. Meanwhile, xAI is developing leading digital AI products and services, such as its large language model (Grok).”
It continued:
“In that context, and as part of Tesla’s broader strategy under Master Plan Part IV, Tesla and xAI also entered into a framework agreement in connection with the investment. Among other things, the framework agreement builds upon the existing relationship between Tesla and xAI by providing a framework for evaluating potential AI collaborations between the companies. Together, the investment and the related framework agreement are intended to enhance Tesla’s ability to develop and deploy AI products and services into the physical world at scale. This investment is subject to customary regulatory conditions with the expectation to close in Q1’2026.”
The history of the partnership traces back to xAI’s founding in July 2023, as Musk launched the company as a counterweight to dominant AI players like OpenAI and Google.
xAI aimed to “understand the true nature of the universe” through unbiased, truth-seeking AI. Tesla, meanwhile, has long invested in AI for its Full Self-Driving (FSD) software and Optimus robots, training models on vast datasets from its vehicle fleet.
The investment holds profound significance for both companies.
For Tesla, it accelerates its Master Plan Part IV, which envisions AI-driven autonomy in vehicles and humanoid robots. xAI’s Grok could enhance Tesla’s real-world AI applications, from optimizing battery management to predictive maintenance, potentially giving Tesla an edge over its biggest rivals, like Waymo.
Investors, on the other hand, stand to gain from this symbiosis. Tesla Shareholders may see boosted stock value through AI innovations, with analysts projecting enhanced margins and significant future growth in robotics. xAI’s valuation could soar, attracting more capital.
