SpaceX's Falcon rockets might need a giant tower on wheels for US military launches
SpaceX reportedly plans to build a massive mobile gantry – effectively a tower on wheels – at one of its two Florida launch pads, a bid to meet obscure military launch criteria needed to secure highly lucrative Falcon 9 and Falcon Heavy launch contracts from the US government.
Although this is not the first time that SpaceX and vertical integration have been thrown around in the same sentence, it is the first time that the company is reportedly close to actually finalizing its plans along those lines and constructing a real solution at one or more of its three orbital-class launch pads.
Throughout the entirety of its active launch operations, SpaceX has relied exclusively on horizontal integration for its Falcon 1, 9, and Heavy rockets and the satellites they launch. CEO Elon Musk and other executives have maintained a consistent rationale for that preference over the years: ensuring that rockets and payloads can be horizontally integrated is the best possible solution so long as SpaceX’s primary motivation is improving access to space and lowering the cost of launch. As such, SpaceX has one and only one major motivation to jerry-rig a vertical integration solution for its Falcon family of rockets: necessity by way of arcane US military launch contract requirements.
Spaceflight Now broke the latest news first on January 3rd, 2020, revealing that SpaceX was at long last taking a substantial step towards actually building its own vertical integration infrastructure at Kennedy Space Center (KSC) Launch Complex 39A – a step that was long anticipated but has taken years to transpire into anything concrete. The gist is this: for a variety of seemingly shoehorned and far-from-obvious reasons, the secretive, ultra-expensive spy satellites that contractors like Lockheed Martin and Boeing build for the US Air Force (USAF) and the National Reconnaissance Office (NRO) builds itself are designed in such a way that they apparently cannot be flipped horizontally in a rocket’s payload fairing.
Identical to the process depicted above for Blue Origin’s in-development New Glenn rocket, up to now, SpaceX has encapsulated all satellite payloads vertically, sealed the payload fairing, rotated that integrated fairing and payload, and then attached that assembly to horizontal Falcon 9 and Falcon Heavy rockets. The rocket is then transported to the launch pad on a transporter erector (T/E), which – as the name suggests – raises the rocket and payload vertical before propellant loading and launch.
For certain USAF and NRO launch contracts, breakover (horizontal flip) is unacceptable and their preference is that the launch vehicle be brought vertical before the payload – also still vertical – is stacked on top. While it sounds simple in principle (i.e. “Just stick a crane out by the pad!”), vertical payload integration is exceptionally tedious unless you already have the infrastructure in place. Competitor United Launch Alliance (ULA), for example, already has that infrastructure – having held a decade-long monopoly over US military launches that only ended 5-7 years ago, depending on how it’s measured.
Both ULA’s Atlas V, Delta IV, and soon-to-be Vulcan Centaur rockets and the infrastructure used to launch them have all been designed around vertical payload integration – essentially requiring massive, expensive, and complicated buildings-on-wheels at each launch facility.
Per Spaceflight Now, SpaceX has plans to build a similar mobile tower at Pad 39A, currently dedicated Falcon 9/Crew Dragon missions for NASA and the occasional Falcon Heavy launch. That tower will ultimately roll up to Falcon 9 or Heavy rockets on the pad, fully covering the vehicles and giving technicians an array of work platforms and tools to support vertical payload integration, among other uses. SFN says that the mobile tower will be even taller than the existing Fixed Service Structure (FSS) tower at Pad 39A, measuring some 30 stories (100m/330ft) tall.
In line with a recent FSS redesign that saw that existing tower modified for Crew Dragon and outfitted with semi-transparent black glass or plastic and a black-and-white color scheme, the new mobile tower will apparently be built with a similar design language.
Ultimately, all of SpaceX’s plans for Starship – a massive next-generation, fully-reusable rocket – have relied on some form of vertical integration for Super Heavy boosters, Starships, and tankers. In a best-case scenario, all of those vehicles may one day land in reach of a giant crane situated at the launch pad, allowing SpaceX to lift them back to the pad and install ships and tankers on Super Heavy boosters just hours (maybe even minutes) after touchdown – truly rapid reuse.
For now, it’s unclear when exactly SpaceX wants to start cutting metal for its new Falcon 9/Heavy gantry, but it’s safe to say the company will move fast as usual once it begins.

Tesla AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.
