SpaceX’s Starlink eyed by US military as co. raises $500-750M for development
In a reasonably predictable turn of events, SpaceX has been awarded a healthy $28.7M contract to study, develop, and test possible military applications of its prospective Starlink internet satellite constellation.
Previously reported by Teslarati in August 2018, FCC applications related to Starlink revealed that SpaceX had plans to develop and test Starlink interconnectivity with conformal antenna arrays installed on aircraft, all but directly pointing to military involvement with a reference to the need for aerial maneuvers “[representative] of a high-performance aircraft.”

Around the same time as those FCC documents surfaced, the US Air Force Research Laboratory (AFRL) spoke with AviationWeek about plans to experiment with the potential capabilities offered by a flurry of proposed low Earth orbit (LEO) internet satellite constellations, including the likes of SpaceX’s Starlink, OneWeb, a Telesat network, and others. While no specific companies were fingered in AFRL’s public statements, it was far too convenient to be a coincidence. Four months later, the below transaction was published in the Department of Defense’s running list of new contract awards:
“[SpaceX], Hawthorne, California, has been awarded a $28,713,994 competitive, firm-fixed-price … agreement for experimentation … in the areas of establishing connectivity [and] operational experimentation … [and] will include connectivity demonstrations to Air Force ground sites and aircraft for experimental purposes. For the proposed Phase 2, the awardee proposes to perform experiments [with] early versions of a commercial space-to-space data relay service and mobile connectivity directly from space to aircraft.” – Department of Defense, FBO FA8650-17-S-9300
Those dots were fairly easy to connect earlier this year, but this agreement confirms the apparent arrangement with certainty. Almost three months after SpaceX could have received its initial funding, it’s possible that the company has already begun basic testing along the described lines with the two prototype Starlink satellites currently in orbit, although no FCC or FAA filings (that I am aware of) have suggested that those tests are ongoing. SpaceX may be waiting for the launch of a second generation of Starlink prototype satellites to begin seriously putting its antenna and communications technologies through their mid-air paces.

Early answers to the biggest question
At this point in time, the viability and potential utility of Starlink and other large LEO constellations are well established. What has not been established, however, is how exactly any of the proposed constellations – especially Starlink – can go from paper to orbit. In other words, the reasonable question to ask of any company pursuing such an endeavor is how they plan to fund the acquisition of capital-intensive manufacturing infrastructure and launch services.
Ultimately, SpaceX will receive $19.1M of the full $28.7M sum from the DoD in FY2019 (Oct 1, 2018 to Sept 30, 2019). This absolutely dwarfs all other contracts awarded thus far under the AFRL’s Defense Experimentation Using Commercial Space Internet (DEUCSI) program, which began in August 2017 and has since awarded $2.5M and $5.6M contracts to Iridium and L3, respectively. In the grand scheme of things, ~$30M is a pittance in the face of the extensive investments SpaceX needs to make if it hopes to mass-produce high-performance satellites at a truly unprecedented scale.

This is where a duo of major investment and fundraising developments come into play. In the last several months, word has gotten out that SpaceX secured a respectable $250M loan through the sale of debt, and more recently wrapped up an equity investment round to the tune of $500M, playing off of long-time investors with a demonstrated interest in belief in the company’s long-term vision. For unknown reasons, SpaceX had originally looked into raising the full $750M through a debt-equity loan, but – despite reports that its market was very healthy – soon cut the offering to $500M and eventually $250M, which it ultimately secured in November. Combined with a traditional $500M equity-investment uncovered earlier this month, SpaceX appears to have nearly completed fundraising of more than $750M in the second half of 2018 alone.

Put a different way, SpaceX has very rapidly gotten very serious about doubling down on Starlink. According to the Wall Street Journal, who originally broke the news of a new $500M equity round, that funding is to be predominately focused on getting Starlink up and running as a serious venture capable of mass-producing satellites. According to a recent Reuters analysis of the Starlink program, CEO Elon Musk challenged the company to begin dedicated launches of operational Starlink satellites as early as June 2019, and the company also plans to launch another round of improved (Gen 2) satellite prototypes early next year.

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.
🚨 Tesla has just expanded its Robotaxi geofence in Houston
It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
