Almost five months after SpaceX began the process of filling and testing the first custom-built propellant storage system for Starship, the largest rocket ever built, the company has finally begun to fill the fuel half of the ‘tank farm’.

SpaceX began delivering truckloads of liquid nitrogen (LN2) to the LN2 and liquid oxygen (LOx) sections of the tank farm in mid-September 2021, well before the farm was anywhere close to completion. In about a month, SpaceX accepted ~60 LN2 deliveries – enough to partially fill one of the farm’s seven cryogenic tanks. Instead of some operational purpose, that LN2 was likely used to clean and partially proof the farm’s three LOx tanks. Just two weeks later, the orbital tank farm received its first LOx deliveries.

At the time, mere days after the basic structure of the main tank farm storage system was effectively completed, most figured that it would take SpaceX about as long to clean, proof, and begin filling the farm’s two liquid methane tanks. That would not be the case.

SpaceX installed the second of the farm’s two vertical SpaceX-built cryogenic liquid methane (LCH4) tanks in mid-October 2021. All seven cryogenic tanks had ‘sleeves’ – designed to be filled with foam insulation – installed by the end of the month, effectively completing the farm’s basic structure half a year after assembly began. However, around the same time, SpaceX also installed two horizontal tanks that were also identified as LCH4 storage – giving the overall tank farm far more fuel storage than its oxidizer (LOx) tanks could match. Starship’s Raptor engines burn about 3.55 kilograms of LOx for every 1 kilogram of LCH4.

As work on the vertical LCH4 tanks appeared to slow to a crawl, it took until December 2021 for SpaceX to begin cleaning and proofing the farm’s horizontal LCH4 tanks with liquid nitrogen. By that time, a rough unofficial narrative had been constructed to explain the lack of progress on the farm’s fuel half. Namely, in an excellent Twitter thread, CSI Starbase made a strong case that SpaceX appeared to have designed the first orbital-class Starship tank farm – a compact and pleasingly symmetric set of eight vertical storage tanks – without taking into consideration rudimentary Texas regulations for the storage of liquid natural gas and methane. By all appearances, that conclusion was correct, as the farm was visibly violating several rules – namely the requirements that all LCH4 storage be surrounded by six-foot-tall retaining walls and that all associated plumbing not be situated under power cabling.

As it exists, the LCH4 side of the vertical tank farm violates both of those rules and it’s not obvious that there is actually enough space between the two vertical methane tanks to build a retaining wall with two feet of horizontal clearance. It’s possible that the situation is more complex and that SpaceX intentionally broke those rules or was pursuing an exception to them but the end result was that those vertical LCH4 tanks have yet to be finished, let alone cleaned or proof tested. Instead, SpaceX appears to have fully refocused on horizontal tanks and most recently tore down a dirt berm beside them and began preparing foundations for at least two or three more.

Those horizontal tanks appear to store about 1000 cubic meters (~35,000 ft^3) of LCH4, while the vertical tanks would have stored about 1800 m^3. To fully replace them, SpaceX will need approximately four horizontal tanks – two more in addition to the two already installed. Thankfully, SpaceX has finally begun filling the already installed tanks while it works to expand the methane farm, beginning with three truckloads on the very first day – February 13th, 2022.

To fill the two existing tanks, which may store enough methane to fuel a stacked Starship and Super Heavy about 4/5ths of the way, SpaceX will need around 40-50 more tanker deliveries. Since last November, SpaceX has completed more than 320 liquid nitrogen and 200 liquid oxygen deliveries – equivalent to about 6700 tons (~14.8M lb) of LN2 and 4200 tons (~9.3M lb) of LOx. If SpaceX maintains that average and focuses entirely on LCH4, the two horizontal tanks could be filled to the brim before the end of February.

Having a substantial amount of LCH4 stored at the orbital tank farm will finally allow SpaceX to attempt the first major wet dress rehearsals (WDRs) and, more importantly, the first full static fires with flightworthy Super Heavy booster prototypes. Of course, a tank farm with full supplies of LOx, LCH4, LN2, and their gaseous equivalents is also a necessity for the first orbital Starship launch attempt, which has most recently slipped from a target of mid-2021 to no earlier than (NET) Q2 2022, pending regulatory approval.

SpaceX to launch military missile tracking satellites through new Space Force contract

SpaceX wins a $178.5M Space Force contract to launch missile tracking satellites starting in 2027.

The U.S. Space Force awarded SpaceX a $178.5 million task order on April 1, 2026 to launch missile tracking satellites for the Space Development Agency. The contract, designated SDA-4, covers two Falcon 9 launches beginning in Q3 2027, one from Cape Canaveral Space Force Station in Florida and one from Vandenberg Space Force Base in California. The satellites, built by Sierra Space, are designed to bolster the nation’s ability to detect and track missile threats from orbit.

The award falls under the National Security Space Launch Phase 3 Lane 1 program, which Space Force uses to move payloads to orbit on faster timelines and at more competitive prices. “Our Lane 1 contract affords us the flexibility to deliver satellites for our customers, like SDA, more easily and faster than ever before to all the orbits our satellites need to reach,” said Col. Matt Flahive, SSC’s system program director for Launch Acquisition, in the official press release.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket

The SDA-4 contract is the latest in a long string of national security wins for SpaceX. As Teslarati reported last month, the Space Force recently shifted a GPS III satellite launch from ULA’s Vulcan rocket to SpaceX’s Falcon 9 after a significant Vulcan booster anomaly grounded ULA’s military missions indefinitely. That move made it four consecutive GPS III satellites transferred to SpaceX after contracts were originally awarded to its competitor.

This didn’t come without a fight and dates back years. SpaceX originally had to sue the Air Force in 2014 for the right to compete for national security launches, at a time when United Launch Alliance held a near monopoly on the market. Since then, the company has steadily displaced ULA as the dominant provider, and last year the Space Force confirmed SpaceX would handle approximately 60 percent of all Phase 3 launches through 2032, worth close to $6 billion.

With missile defense satellites now part of its launch manifest alongside GPS, communications, and reconnaissance payloads, SpaceX is giving hungry investors something to chew on before its imminent IPO.

Tesla’s Q1 delivery figures show Elon Musk was right

On the surface, the numbers reflect a mature EV market facing competition, softening demand, and the loss of certain incentives. Yet they also quietly validate a prediction Elon Musk has repeated for years: Tesla’s traditional auto business is becoming far less central to the company’s future.

Tesla reported its Q1 delivery figures on Thursday, and the figures — solid but unspectacular — show that CEO Elon Musk was right about what the company’s most important production and division would be.

We are seeing that shift occur in real time.

Tesla delivered 358,023 vehicles in the first quarter of 2026, according to the company’s official report released April 2.

The figure represents modest year-over-year growth of roughly 6 percent from Q1 2025’s 336,681 deliveries but a sharp sequential drop from Q4 2025’s 418,227. Production reached 408,386 vehicles, while energy storage deployments hit 8.8 GWh.

On the surface, the numbers reflect a mature EV market facing competition, softening demand, and the loss of certain incentives. Yet they also quietly validate a prediction Elon Musk has repeated for years: Tesla’s traditional auto business is becoming far less central to the company’s future.

Musk has long argued that vehicles alone will not define Tesla’s value.

Optimus Will Be Tesla’s Big Thing

In September 2025, Musk stated bluntly on X that “~80% of Tesla’s value will be Optimus,” the company’s humanoid robot.

He has described Optimus as potentially “more significant than the vehicle business over time.” Those comments were not abstract futurism. In January 2026, during the Q4 2025 earnings call, Musk announced the end of Model S and X production, framing it as an “honorable discharge,” he called it.

The Fremont factory space, once dedicated to those flagship sedans, is being converted into an Optimus manufacturing line, with a long-term target of one million robots per year from that single facility alone.

The Q1 2026 numbers arrive at precisely the moment this strategic pivot is accelerating. Model 3 and Y deliveries totaled 341,893 units, while “other models” (including Cybertruck, Semi, and the final wave of S/X) added 16,130.

Growth is no longer explosive because Tesla is no longer chasing volume at all costs. Instead, the company is reallocating capital and factory floor space toward autonomy, energy storage, and robotics, businesses Musk believes will command far higher margins and enterprise value than incremental car sales.

Delivery Hits and Misses are Becoming Less Important

Wall Street’s pre-release consensus had pegged deliveries near 365,000. Coming in below that estimate might have rattled investors focused solely on automotive metrics. Yet Musk’s thesis has never been about maximizing quarterly vehicle shipments.

Tesla, he has insisted, “has never been valued strictly as a car company.”

The modest Q1 auto performance, paired with the deliberate wind-down of legacy programs and the ramp of Optimus, underscores that point. While EV demand stabilizes, Tesla is building the infrastructure for Robotaxis and humanoid robots that could dwarf today’s car business.

Tesla reports Q1 deliveries, missing expectations slightly

The future is here, and it is happening. It’s funny to think about how quickly Tesla was able to disrupt the traditional automotive business and force many car companies to show their hand. But just as fast as Tesla disrupted that, it is now moving to disrupt its own operation.

Cars, once the only recognizable and widely-known division of Tesla, is now becoming a background effort, slowly being overtaken by the company’s ambitions to dominate AI, autonomy, and robotics for years to come.

Critics may still view the shift as risky or premature. But the Q1 figures, solid but unspectacular in the auto segment, illustrate exactly what Musk has been signaling: the era when Tesla’s valuation rose and fell with every Model Y delivery is ending.

The company’s long-term bet is on AI-driven products that turn vehicles into high-margin robotaxis and factories into robot foundries. Thursday’s delivery report did not just meet the market’s tempered expectations; it proved Elon Musk was right all along.

The car business, once everything, is quietly becoming an important piece of a much larger puzzle.

Tesla reports Q1 deliveries, missing expectations slightly

The figure, however, fell short of Wall Street’s consensus estimate of 365,645 units, reflecting ongoing headwinds in the global EV market.

Tesla reported deliveries for the first quarter of 2026 today, missing expectations set by Wall Street analysts slightly as the company aims to have a massive year in terms of sales, along with other projects.

Tesla delivered 358,023 vehicles in the first quarter of 2026, marking a 6.3 percent increase from 336,681 vehicles in Q1 2025.

The figure, however, fell short of Wall Street’s consensus estimate of 365,645 units, reflecting ongoing headwinds in the global EV market. Production reached approximately 362,000 vehicles, with Model 3 and Model Y accounting for the vast majority. The results come as Tesla navigates softening demand, intensifying competition in China and Europe, and the expiration of key U.S. federal tax incentives.

Energy storage deployments provided a bright spot, hitting a record 8.8 GWh in Q1. This underscores the accelerating momentum in Tesla’s energy segment, which has become a critical growth driver even as automotive volumes stabilize.

Year-over-year, the energy business continues to outpace vehicle sales, with analysts noting strong backlog demand for Megapack systems amid rising grid-scale needs for renewables and AI data centers.

Looking ahead, analysts project full-year 2026 vehicle deliveries in the range of 1.69 million units—a modest 3-5% rise from roughly 1.64 million in 2025.

Growth is expected to accelerate in the second half as production ramps and new incentives emerge in select markets. However, risks remain: persistent high interest rates, price competition from legacy automakers and Chinese EV makers, and potential margin pressure could cap upside.

Tesla has not issued official full-year guidance, but executives have signaled confidence in sequential quarterly improvements driven by cost reductions and refreshed lineups.

By the end of 2026, Tesla plans several major product launches to reignite momentum. The refreshed Model Y, including a new 7-seater variant already rolling out in select markets, is expected to boost family-oriented sales with updated styling, efficiency gains, and interior enhancements.

Autonomous ambitions remain central to Tesla’s mission, and that’s where the vast majority of the attention has been put. Volume production of the Cybercab (Robotaxi) is targeted to begin ramping in 2026, potentially unlocking new revenue streams through unsupervised Full Self-Driving (FSD) deployment.

A next-generation affordable EV platform, possibly under $30,000, is also in advanced planning stages for 2026 or 2027 introduction. On the energy front, the Megapack 3 and larger Megablock systems will drive further deployment scale.

While Q1 highlights transitional challenges in autos, Tesla’s diversified roadmap, spanning refreshed consumer vehicles, commercial trucks, Robotaxis, and explosive energy growth, positions the company for a stronger second half and beyond. Investors will watch Q2 closely for signs of sustained recovery, especially with new vehicles potentially on the horizon.
