SpaceX may have signed a fairing agreement with ULA supplier RUAG (Update: no agreement)
According to unverified and speculative comments reportedly made to a member of the space industry by a RUAG spokesperson, the prominent aerospace supplier may have reached an agreement with SpaceX to manufacture a handful of larger payload fairings for future Falcon 9 and Heavy launches.
In the likely event that SpaceX is one of two contractors awarded a portion of several dozen US military launch contracts next year, the company will need to be able to cater to niche requirements, including accommodating unusually tall military satellites. Those satellites can be so tall that SpaceX’s own payload fairing – generally middle-of-the-pack relative to competitors’ offerings – may be too short, meaning that SpaceX will have to find ways around that minor shortcoming.
Update: Tim Chen has retracted his earlier comments and has stated that there is actually no agreement currently in place with SpaceX for RUAG to produce taller fairings out of its new Decatur, AL factory.
Additionally, ULA CEO Tory Bruno clarified that the company’s “[new fairing] has [ULA] intellectual property in its design and manufacture … [and] is currently planned only for use on Atlas and Vulcan”, meaning that any cooperation between SpaceX and RUAG would likely require a new production facility and a somewhat different fairing design.
“ULA’s new fairing, which is built in our factory in Decatur, has our intellectual property in its design and manufacture. This fairing is currently planned only for use on Atlas and Vulcan. You would want to ask RUAG about business they might have with their other customers.”
Tory Bruno, August 14th, 2019
Regardless of the veracity of these recent claims, it appears that SpaceX has three obvious responses at its disposal: design and build an entirely new variant of its universal Falcon fairing, purchase the necessary fairings from an established supplier, or bow out of launch contract competitions that demand it. The latter option is immediately untenable given that it could very well mean bowing out of the entire US military competition, known as Phase 2 of the National Security Space Launch program’s (NSSL; formerly EELV) Launch Services Procurement (LSP).
For dubious reasons, the US Air Force (USAF) has structured the NSSL Phase 2 acquisition in such a way that – despite there being four possible competitors – only two will be awarded contracts at its conclusion. The roughly ~30 launch contracts up for grabs would be split 60:40 between the two victors, leaving two competitors completely emptyhanded. In short, bowing out of the Phase 2 competition could mean forgoing as many as one or two-dozen contracts worth at least $1-2B, depending on the side of the 60:40 split.
According to a handful of recent comments and developments, SpaceX has likely sided with the option of procuring taller fairings from an industry supplier. As it turns out, European company RUAG has effectively cornered the Western rocket fairing market, with SpaceX being the only Western launch company currently building its own fairings. RUAG builds fairings for both Arianespace’s Ariane 5 and Vega rockets and ULA’s Atlas V. Additionally, RUAG will build and supply fairings for both companies’ next-gen rockets – Arianespace’s Ariane 6 and ULA’s Vulcan – and builds fairings for a number of smallsat launch companies.
Comments made in June by a RUAG official confirmed that there was some semblance of a relationship between SpaceX and RUAG for the purpose of satisfying USAF needs for taller fairings, although the phrasing suggested that the cooperation was in its early stages and nothing had been solidified.
“In a June 12 letter to Smith, the company’s CEO Peter Guggenbach makes the case that legislation forcing access to suppliers is unnecessary in this case because RUAG does not have an exclusive arrangement with ULA and is willing to work with SpaceX or any other launch providers.
“For this competition, we are in the process of submitting or have submitted proposals to multiple prime contractors regarding launch vehicle fairings. In those agreements, we share technical data to support a prime contractor’s bid while protecting our intellectual property.”
RUAG vice president Karl Jensen told SpaceNews the company has a “significant partnership” with ULA but is looking to work with others too. “We have an offer to SpaceX,” he said. “We don’t know if they’ll accept it.”
SpaceNews, 06/13/2019
Interestingly, although ULA’s RUAG-built Atlas V fairing is slightly narrower than SpaceX’s 5.2m (17 ft) diameter fairing, Atlas V’s largest fairing is significantly taller, supporting payloads up to 16.5m (54 ft) tall compared to 11m (36 ft) for Falcon 9 and Heavy. Given that just a tiny portion of military spacecraft actually need fairings that tall, SpaceX is apparently not interested in simply modifying its own fairing design and production equipment to support a 20-30% stretch.
This likely relates in part to the fact that one of SpaceX’s three NSSL Phase 2 competitors – Northrop Grumman (Omega), Blue Origin (New Glenn), and ULA (Vulcan) – are guaranteed to receive hundreds of millions of dollars of development funding after winning one of the two available slots (60% or 40% of contracts). SpaceX, on the other hand, will receive no such funding while still having to meet the same stringent USAF requirements compete in LSP Phase 2. Of note, Congressman Adam Smith managed to insert a clause into FY2020’s defense authorization bill that could disburse up to $500M to SpaceX in the event that the company is one of Phase 2’s two winners.
Despite this potential influx of infrastructure-focused funds, SpaceX may still be pursuing taller Falcon fairings from RUAG as a backup in the event that the company is not one of the two Phase 2 winners or is unable to use some of the $500M secured by Rep. Smith to develop its own stretched fairing.
On August 12th, SpaceX – along with Blue Origin, ULA, and NGIS – submitted bids for NSSL Phase 2 launch services, confirming that all four companies will indeed be in the running for contracts. The USAF is not expected to announce the results of this competition until Q2 2020.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.
Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”
The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.
Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.
| Configuration | Seats | 0 to 60 mph |
|---|---|---|
| Performance | 2 | under 1.6 s |
| Thrust | 2 | under 0.9 s |
| Rocket | 1 | under 0.59 s |
Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.
Every car on the road today is limited by one thing: tire grip
Roadster’s thruster system generates 4–5x the force the tires can.
More force on the same mass means significantly better acceleration – physics does the rest https://t.co/zdPRT2aKwZ

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store
Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.
Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.
The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.
The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.
Just ask Grok @Bot to buy what you want someplace else and get a better deal.
There are far more purchasing websites than just Amazon!
— Elon Musk (@elonmusk) October 15, 2026
The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.
The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.
The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.
Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.
So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
