SpaceX’s Falcon 9 and Falcon Heavy win $297M in US military launch contracts
SpaceX and competitor United Launch Alliance (ULA) have been awarded three US military launch contracts apiece with an overall value of $297M (SpaceX) and $442M (ULA). While unconfirmed, this could mark the fourth launch contract awarded to Falcon Heavy in just half a year.
Set to nominally launch between 2021 and 2022, SpaceX received two contracts from the National Reconnaissance Office (NROL-85 and -87) and one from the USAF (AFSPC-44), while ULA received two missions from the USAF (SBIRS-5 and -6) and one from NRO (SILENTBARKER). While the announcement did not specify launch vehicle arrangements, it’s safe to assume that ULA will be flying SBIRS on Atlas V, while SpaceX will likely fly both NROL payloads on Falcon 9.

“SpaceX is proud that the Air Force has chosen our company to support our country’s defense with these critical national security space launches and to continue providing the best value in launch with the proven Falcon 9 and Falcon Heavy vehicles.” – SpaceX President & COO Gwynne Shotwell, 02/19/2019
“This is a full and open competition. … At present, ULA is the only launch provider certified for the SILENTBARKER and AFSPC-44 missions. However, it is anticipated that in the near future SpaceX will be launching the Falcon Heavy, which may be capable of meeting the SILENTBARKER and AFSPC-44 requirements.” – USAF SMC, 02/02/2018
In official comments made in a follow-up to the finalized RFP (requests for proposals) for the launch contracts the US military awarded On Feb. 19, 2019, the USAF Space and Missile Systems Center (SMC) offered some insight into the thought processes going on behind the scenes of the procurement initiative. While almost nothing is known about the payloads themselves, SMC appeared to confirm that SILENTBARKER (believed to be NROL-107) and AFSPC-44 could only be launched on ULA rockets at the time (Feb. 2018), although SpaceX’s Falcon Heavy was also reportedly an option. Provided just a few days before Falcon Heavy’s launch debut, SMC’s tentative inclusion of FH was understandable.

For a bit of historical context, SpaceX completed its first NRO mission (NROL-76) in May 2017 for an unknown sum, although safe estimates peg the Falcon 9 launch cost somewhere around $80-100M. SpaceX’s first official USAF EELV mission, the first upgraded GPS III satellite, was completed in December 2018 for around $82M (2016) and won an additional three GPS III launch contracts at an average per-mission value of ~$97M. Each GPS III satellite is estimated to cost no less than $573M, while the last four SBIRS (Space-Based Infrared System) geostationary satellites infamously wound up costing more than $1.7 billion apiece as a consequence of prime contractor Lockheed Martin incurring multiple delays and breaching price targets. SBIRS-5 and -6 were said by a Lockheed Martin executive to likely cost “20% less” than SBIRS 1-4, implying that each spacecraft will carry a price tag of at least $1.4B.
Given the sheer cost of the spacecraft and the Air Force’s stance on the SBIRS constellation being a critical part of ballistic missile early-warning defenses, it’s not particularly surprising that Atlas V was chosen over Falcon 9 or Falcon Heavy, a decision likely made to minimize latent risk – however little.

Falcon Heavy – contract #6?
In June 2018, the USAF announced that it had officially certified Falcon Heavy for Air Force missions and awarded SpaceX’s newest launch vehicle a $130M contract to launch its Air Force Space Command-52 spacecraft (AFSPC-52) in 2020. Weighing around 6350 kg (14,000 lbs), Falcon Heavy is tasked with placing the spacecraft into a geostationary transfer orbit of 185 by 35,188 kilometers (115 by 21,900 miles), a mission profile that curiously should be within the performance capabilities of an expendable Falcon 9. If AFSPC-44 is similar to -52, it could be launched by either SpaceX rocket and SMC’s vague $297M award fails to answer any questions thanks to the uncertainty of SpaceX NRO contract pricing. Still, it can be easily determined that SpaceX’s average launch cost ($99M) trounces ULA’s ($147M) by nearly 50%, potentially saving the US government and taxpayer a bit less than $150M.

Aside from AFSPC-52 and perhaps AFSPC-44, Falcon Heavy received an additional two commercial contracts from Swedish communications firm Ovzon and US company Viasat in October 2018. Following its February 2018 debut, the rocket’s next two missions (Arabsat 6A and USAF STP-2) are also imminent, with current info pointing to launch targets in March and April 2019, respectively. Combined, Falcon Heavy may now have six solid launch contracts manifested from 2019 to 2021. Meanwhile, NASA and international partners ESA and JAXA (among others) continue to express interest in and work towards the creation of a miniature crewed space station (“Gateway”) in an unusual orbit around the Moon, an aspiration the success of which will heavily depend on affordable commercial launches of a variety of Gateway components and resupply missions, at minimum.
If NASA’s Gateway and crewed Moon lander programs survive the United States’ 2020 election cycle, Falcon Heavy could be called into action as early as 2022 and have numerous additional contract opportunities in the 4+ years following. Ultimately, the US military’s Feb. 19 launch awards confirm that the taxpayer continues to reap the benefits of competition SpaceX has reintroduced into the monopolized US launch industry, while also reiterating the health and commercial value of SpaceX’s Falcon Heavy investment.

Starlink is ‘biggest competitive advantage,’ but it’s temporary, United CEO says
United Airlines CEO Scott Kirby said that SpaceX’s Starlink satellite internet is its leading competitive advantage in the U.S. airline industry. However, in recent comments, while he described the service as “the biggest competitive advantage” the carrier currently holds, he also acknowledged that the edge is temporary.
“…everybody eventually is going to have high-speed low earth orbit internet connectivity. It’s going to be a must-have. We are going to have a few years of being the only airline that has it at scale, and that’s our mission,” Kirby said. Until everyone has it, United aims to capitalize on its head start by converting trial users into long-term loyal customers.
🚨 United CEO Scott Kirby calls Starlink “the biggest competitive advantage,” but says it’s temporary.
“I think it’s the biggest competitive advantage. And it’s temporary. Like it’s not, everybody eventually is going to have high speed low earth orbit internet connectivity. It’s going to be a must-have. But we are going to have a few years of being the only airline that has it at scale, and that’s our mission.”
“I think we’re going to convince customers that United is the best airline and we’re going to get customers to switch their loyalty, to get our credit card, switch their loyalty to United. Not because of Starlink. They’re going to try us for Starlink and they’re going to stay with all the other technology, and everything else is better, and the technology in particular is so much better than technology other, and it’s accelerating because we’ve got the right tech stack, and because we’re like, our gap is getting wider and wider with our technology every day.”
Next: LAX becomes United’s first 100% Starlink hub in the first half of next year, and the United app will show your Starlink odds for each flight. https://t.co/hToyFWaWj7

United has moved faster than its rivals on Starlink installations. As of mid-to-late October 2026, the system was on roughly 43 percent of its fleet, with plans to reach 61 percent by year-end, 87 percent by June 2027, and full fleet coverage by the end of next year.
The airline already operates more Starlink-equipped flights than the rest of the U.S. industry combined. Los Angeles International Airport is scheduled to become United’s first 100 percent Starlink hub in the first half of 2027, and the carrier’s app will display the likelihood that any given flight has the service.
Kirby has pointed to early evidence that the offering influences booking decisions. Some passengers loyal to other airlines are already switching flights for Starlink connectivity, something the airline, along with American Airlines, has tried to leverage against competing airlines. Both companies used status-match programs, and some of those customers are pursuing company-specific credit cards, which signals an intent to stay.
Once onboard, these customers encounter the airline’s broader investments in aircraft, larger seat-back screens, oversized bins, connection tools, and a mobile app that Kirby says outperforms competitors. Wi-Fi satisfaction scores on Starlink-equipped planes have been reported to be nearly double those on aircraft with other systems.
Competitors are moving slowly to do the same. Southwest Airlines began installations in 2025 and expects to complete them soon. Delta is pursuing Amazon’s Leo system, while American expects to start Starlink work in early 2027 and has not yet detailed regional-fleet plans. This timeline gap gives United a multi-year window in which it remains the only major U.S. carrier offering Starlink at scale.
Kirby has framed the strategy as pressing that advantage while simultaneously widening gaps in other technology areas so that customers who try United for the Wi-Fi remain for the overall experience.
The approach reflects a calculated bet that superior in-flight connectivity can accelerate share gains and support longer-term financial targets, including a 10 percent pre-tax margin goal.
High-speed internet is particularly valued by premium and business travelers who can work or stream reliably. As low-Earth-orbit service becomes ubiquitous, the temporary nature of the pure connectivity edge means United’s retention will depend on whether its other product and operational improvements keep pace.

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady
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
— TESLARATI (@Teslarati) October 26, 2026
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 expands Robotaxi geofence in Houston with an ode to SpaceX merger
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
— TESLARATI (@Teslarati) October 26, 2026
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.
