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.

Tesla’s last chance version of the flagship Model X is officially gone
The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Tesla enabled a last-chance version of its two flagship vehicles, the Model S and Model X, over the past few weeks. The Model X, the company’s original SUV, is officially gone.
Tesla has officially closed the book on its most exclusive send-off for the Model X. The limited-run Model X Signature Edition—priced at $159,420 before fees and limited to just 100 units—is now sold out, with reservations closed as of April 16.

The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Every unit featured an exclusive Garnet Red exterior paint, unique badging, and a standard six-seat configuration. With full Plaid powertrain specs—Tri-Motor All-Wheel Drive, over 1,000 horsepower, and blistering acceleration—it was positioned as a collector’s item for loyalists who wanted one last shot at owning a piece of Tesla history.
The timing is no coincidence.
Tesla announced earlier this year that it would discontinue regular production of both the Model S and Model X to repurpose the Fremont factory’s dedicated lines for mass production of its Optimus humanoid robots.
Elon Musk has repeatedly emphasized that Optimus could ultimately become more valuable to the company than its vehicle business, with ambitions to build hundreds of thousands of units annually.
The Signature Editions served as a final “runout” series: 250 for the Model S and only 100 for the Model X, all built to the highest Plaid specification before the line is converted.
Deliveries of the remaining Signature units are scheduled to begin in May 2026. For buyers who secured one, it’s the ultimate swan song for a vehicle that helped define Tesla’s early luxury EV dominance.
Launched in 2015, the Model X introduced falcon-wing doors, a panoramic windshield, and class-leading performance that turned heads and set benchmarks. While newer models like the Cybertruck and refreshed Model Y have taken center stage, the Model X Plaid remained a halo product for those seeking maximum range, space, and speed in an SUV package.
With inventory of standard Model X units already nearly exhausted across the U.S., the rapid sell-out of the Signature Edition underscores enduring demand for Tesla’s premium flagships even as the company pivots toward robotics and autonomy.
For enthusiasts, these 100 garnet-red SUVs will likely become instant collector’s items—tangible reminders of the vehicles that built the brand before Tesla’s next chapter fully begins. The last chance is gone, but the legacy endures.

Tesla Optimus V3 hand and arm details revealed in new patents
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
Tesla is planning to soon reveal its latest and greatest version of the Optimus humanoid robot, and a series of new patents for the hands and arms, with the former being, admittedly, one of the most challenging parts of developing the project.
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
The designs relocate heavy actuators to the forearm, route cables through a sophisticated wrist design, and employ innovative joint assemblies to achieve human-like dexterity while enabling lightweight construction and high-volume manufacturing.
Core Tendon-Driven Hand Architecture
The primary patent, which is titled “Mechanically Actuated Robotic Hand,” details a cable/tendon-driven system.
Actuators are positioned in the forearm rather than the hand. Each finger features four degrees of freedom (DoF), while the wrist adds two more.
Tesla’s Optimus V3 robot hand looks to have been revealed in a new international patent published today.
The patent describes a tendon/cable-driven hand:
• Actuators in the forearm
• Each finger has 4 degrees of freedom
• The wrist has 2 degrees of freedom
• Tendon-driven… pic.twitter.com/eE8xLEYSrx— Sawyer Merritt (@SawyerMerritt) April 16, 2026
Three thin, flexible control cables (tendons) per finger extend from the forearm actuators, pass through the wrist, and connect to the finger segments. Integrated channels within the finger phalanges guide these cables selectively—routing behind some joints and forward of others—to enable independent bending without unintended motion.
Patent diagrams illustrate thick cable bundles emerging from the wrist into the palm and fingers, with labeled pivots and routing guides. This setup closely mirrors human forearm-muscle and tendon anatomy, where most hand control originates proximally.
Advanced Wrist Routing Innovation
One of the standout features is the wrist’s cable transition mechanism. Cables shift from a lateral stack on the forearm side to a vertical stack on the hand side through a specialized transition zone.
Boom! @Tesla_Optimus 의 3세대 구조로 추정되는, 로봇 팔 및 관절에 대한 특허가 공개되었습니다.
아티클 작업에 들어가겠습니다.
1년 넘게 기다려 온, 정말 귀한 특허인데, 조회수 100만대로 터져줬으면 좋겠네요. 😉@herbertong @SawyerMerritt@GoingBallistic5 @TheHumanoidHub pic.twitter.com/CCEiIlMFSX

This geometry significantly reduces cable stretch, torque, friction, and crosstalk during combined yaw and pitch wrist movements — common failure points in simpler tendon systems that cause imprecise or jerky motion.
By minimizing these issues, the design supports smoother, more reliable multi-axis wrist operation, essential for complex real-world tasks.
Companion Patents on Appendage and Joint Design
Two supporting patents provide additional depth. “Robotic Appendage” covers the overall forearm-to-palm-to-finger assembly, with a palm body movably coupled to the forearm and finger phalanges linked by tensile cables returning to forearm actuators. Tensioning these cables repositions the phalanges precisely.
“Joint Assembly for Robotic Appendage” describes curved contact surfaces on mating structures paired with a composite flexible member. This allows smooth pivoting while maintaining consistent tension, enhancing durability, and simplifying assembly for mass production.
Executive Insights on Hand Development Challenges
Tesla executives have consistently described the hand as the most difficult component of Optimus.
Elon Musk has called it “the majority of the engineering difficulty of the entire robot,” emphasizing that human hands possess roughly 27–28 DoF with an intricate tendon network powered largely by forearm muscles. He has likened the challenge to something “harder than Cybertruck or Model X… somewhere between Model X and Starship.”
In mid-2025, Musk acknowledged that Tesla was “struggling” to finalize the hand and forearm design. By early 2026, he stated that the company had overcome the “hardest” problems, including human-level manual dexterity, real-world AI integration, and volume production scalability.
He estimated the electromechanical hand represents about 60 percent of the overall Optimus challenge, compounded by the lack of an existing supply chain for such precision components.
These patents directly tackle the acknowledged pain points: relocating actuators reduces hand mass and inertia for better speed and efficiency; advanced wrist routing and joint geometry address friction and crosstalk; and simplified, stackable parts visible in the diagrams indicate readiness for high-volume manufacturing.
Implications for Optimus Production and Leadership
Collectively, the patents portray the Optimus v3 hand not as a mere prototype, but as a production-oriented system engineered from first principles.
The 22-DoF architecture, forearm-driven tendons, and crosstalk-minimizing wrist deliver a clear competitive edge in dexterity. They align with Musk’s view that high-volume manufacturing is one of the three critical elements missing from most other humanoid projects.
For Optimus to become the most capable humanoid robot, its hand needed to replicate the useful and applicable design of the human counterpart.
These filings demonstrate that Tesla has transformed years of engineering challenges into patented, elegant solutions — positioning the company strongly in the race toward general-purpose robotics.

Tesla intertwines FSD with in-house Insurance for attractive incentive
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla intertwined its Full Self-Driving (Supervised) suite with its in-house Insurance initiative in an effort to offer an attractive incentive to drivers.
Tesla announced that its new Safety Score 3.0 will automatically have a perfect score of 100 with every mile driven with Full Self-Driving (Supervised) enabled.
The change is designed to boost customers’ average safety scores and deliver noticeably lower monthly premiums.
The move marks the clearest link yet between Tesla’s autonomous driving technology and its proprietary insurance product. Tesla Insurance already relies on real-time vehicle data—such as acceleration, braking, following distance, and speed—to calculate a Safety Score between 0 and 100. Higher scores have long translated into cheaper rates.
Under the previous system, however, even brief manual interventions could drag down the average, frustrating owners who rely heavily on FSD. Version 3.0 eliminates that penalty for supervised autonomous miles, effectively treating FSD-driven segments as the safest possible driving behavior.
The incentive is immediate and financial. Drivers who keep FSD engaged for the majority of their trips will see their overall score rise, potentially shaving hundreds of dollars off annual premiums.
Tesla framed the update as a direct response to customer feedback, many of whom had complained that the old scoring model punished the very behavior it was meant to encourage.
For now, the program applies only to new policies in six states: Indiana, Tennessee, Texas, Arizona, Virginia, and Illinois.
Existing policyholders are not yet included, a point that drew swift questions from the Tesla community. Many owners in other states, including California and Georgia, expressed hope that the benefit would expand nationwide soon.
The announcement arrives as Tesla continues to roll out FSD Supervised updates and push for regulatory approval of more advanced autonomy. By tying insurance savings directly to FSD usage, the company is putting its own actuarial weight behind the technology’s safety claims.
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla has not disclosed exact premium reductions or the full rollout timeline beyond the six launch states.
Still, the message is clear: the more drivers trust FSD Supervised, the more Tesla Insurance will reward them. In an era when legacy insurers remain cautious about autonomous tech, Tesla is betting that its own data will prove the safest miles are the ones driven hands-free.
