Musk calls out SpaceX rival for receiving billion dollar subsidy, ULA head fires back
Following an intriguing SpaceX testimony before Senate committees in Washington D.C., Musk took to Twitter to share some thoughts on the state of the launch marketplace and SpaceX’s place within it. It didn’t take long for him to relate a somewhat common critique of the United Launch Alliance, SpaceX’s only American competition.
Sorry. That is simply not true. There is no "billion dollar subsidy". Amazing that this myth persists.

Tory Bruno, President and Chief Executive of ULA, responded with gloves off just a few hours later, deeming the implied existence of such a subsidy nothing more than a “[persistent] myth”. He spent fifteen or so minutes replying to skeptical and inquisitive followers on Twitter, stating that the Wikipedia paragraph on the subject was incorrect. Bruno was steadfast in his response saying that he had publicly testified on the public procurement process before Congress (he did, and he did not defer on the term “subsidy”), and he adamantly refused to back down on his statement that such a subsidy only existed in mythology.
For better or for worse, Bruno is correct to a large extent. In fact, he published a full editorial on the controversial subject in the canonical SpaceNews Magazine. The ELC (EELV (Evolved Expendable Launch Vehicle) Launch Contract) is the source of this controversy, and while not quite a full billion dollars, the FY2016 ELC contract was for $860 million.
SpaceX has admittedly been chronically doubted and mistreated in the realm of government contracting, and ULA has been less than perfectly civil in the past. Simply by existing, SpaceX in effect disrupted what was a American launch industry monopoly held between Boeing and Lockheed Martin. Those two companies merged their space endeavors approximately 11 years ago and have since been the United Launch Alliance. For reasons that do make a bit of sense but are still mildly obtuse, the United States Air Force chose to purchase ULA launch vehicles and the services that make the launch of those vehicles possible separately. The main given reason for this choice, as explored in Bruno’s editorial, is to give the Air Force added flexibility.
As discussed in the 2016 ELC contract itself, another large need for this type of funding lies in the maintenance of a large workforce, and the constant depreciation of both the Atlas and Delta families of launch vehicles. The Delta family, known mainly for the large Delta IV Heavy, is almost never utilized at this point in time, with Atlas being both more cost effective and more reliable. Regardless, due to contracting, ULA is required to maintain both the workforce and facilities necessary to produce and launch Delta vehicles, in spite of having nearly no “business” thanks to Atlas V. Maintaining a workforce and set of facilities that is in part or whole redundant is not efficient or cost-effective, but it is contractually required. So, while the ELC contract Musk deemed a nearly pointless subsidy does have some major flaws, inefficiencies, and illogical aspects, it is not technically correct to label it a subsidy.
-
- Operated by the same company responsible for the F-35, Atlas 5 is a highly reliable and equally expensive rocket. (ULA)
-
- Delta IV Heavy, the only current American heavy lift launch vehicle in service. Once operational, Falcon Heavy will be capable of launching nearly double the payload to GTO. (USAF/ULA, 2013)
Without the actual contract information, it is also difficult to know if ULA would still receive this contractual payment in lieu of conducting actual launches. Bruno frames it in such a way that it sounds like the U.S. government modifies the payment size based on the number and type of required launches for a given year. If the multi-year agreement means that launches delayed many months or more can still be swapped out at no additional charge, then this does indeed make a certain amount of sense. The array of discussion on the subject nevertheless fails to explore the consequences of launch provider-side issues, the likes of which ULA and Atlas 5 experienced earlier this year, resulting in some amount of delays.
We do that too, but for free

While there can be no doubt that the actual gritty details of the ELC contracts deal explicitly with such possible outcomes, the lack of transparency (be that as a result of publicly inaccessible contract details or highly obtuse and lingo-heavy contract language) ultimately frames ELC contracts and the vehemence with which ULA defends them as a wasteful, overly complex, and unnecessary alternative to simply offering a fixed product with services inherently included, as SpaceX does.
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.
