SpaceX competitor ULA CEO still questions the economic value of reusable rockets
SpaceX has made a name for itself for being one of the only private space companies today to deploy a fleet of rockets that are capable of being reused for multiple missions. Elon Musk has sworn by the economics of rocket reusability, and this is shown by SpaceX’s launch prices compared to competitors that use expendable rockets. Yet for Tory Bruno, the CEO of ULA, the economic sense behind reusable rockets like the Falcon 9 is still questionable.
Interestingly enough, the ULA is poised to use Blue Origin’s BE-4 engines for the first stage of its expendable Vulcan rocket. Like SpaceX, Blue Origin’s vision of spaceflight involves rockets that can be reused multiple times before they are retired. ULA, for its part, notes that it may decide to recover and reuse the Vulcan’s BE-4 engines down the road, using a system that disengages the units after launch and having them fall back through the atmosphere while being protected by an inflatable hypersonic shield.
A helicopter would then be positioned to catch the engine section midair while it makes its descent. ULA has come up with a noteworthy name for this system: the Sensible Modular Autonomous Return Technology, or SMART approach. In a statement to Aviation Week, ULA CEO Tory Bruno explained the strategy behind the company’s SMART strategy.
“It does not impact, in any significant way, the overall performance of the launch vehicle because you don’t have to save fuel to fly home with. You still get to burn up all your fuel, separate your engine, which is the most expensive piece, and recover it,” Bruno said.
Elaborating further, the ULA CEO mentioned that ultimately, he believes that the economics of reusable rockets is still up for question. Bruno argued that it is still difficult to ensure that using reusable rockets instead of expendable machines actually saves money.
“We have not really changed our assessment over the last couple of years because we have yet to see the other forms of reusability—flyback or propulsive return to Earth—demonstrate economic sustainability on a recurring basis. It’s pretty darn hard to make that actually save money… We’ve seen nothing yet that changes our analysis on that,” the ULA CEO said.
The ULA CEO’s points about the possible lack of savings on reusable rockets put him in stark contrast with other noteworthy leaders in the space industry. Apart from SpaceX CEO Elon Musk, fellow billionaire Jeff Bezos of Blue Origin is also intently focused on using reusable rockets. Even Rocket Lab CEO Peter Beck, whose company designs and launches small rockets, has embraced the idea of reusing previously-flown boosters.
In a statement in August 2019, for example, Beck noted that he actually had to “eat his hat” when it came to reusing his company’s rockets. “For a long time, I said we weren’t going to do reusability. This is one of those occasions where I have to eat my hat,” the Rocket Lab CEO said.
That being said, the fact that the ULA CEO is considering reusing the Vulcan’s BE-4 engines may be considered as a small win for reusable rockets. Perhaps in the near future, Bruno would see exactly why SpaceX has grown so much over the years, and why the company is practically launching its Starlink satellite internet system at a minimal cost.
“We view (rocket reuse) as sort of a journey. We’re going to start with the engines because we’re pretty sure we can save money with that and pass those savings on right away. As we learn more by doing, we’ll continue to assess other valuable parts of the rocket, and we may discover that we can do that there as well.
“There is one funny thing about reusability. As you make your rocket less expensive, and you make parts of your rocket less expensive, it’s harder to close a business case on reuse because the thing you’re recovering isn’t as valuable. There’s a balance there,” Bruno said.
Tesla has officially launched public Robotaxi rides in Austin, Texas, without a Safety Monitor in the vehicle, marking the first time the company has removed anyone from the vehicle other than the rider.
The Safety Monitor has been present in Tesla Robotaxis in Austin since its launch last June, maintaining safety for passengers and other vehicles, and was placed in the passenger’s seat.
Tesla planned to remove the Safety Monitor at the end of 2025, but it was not quite ready to do so. Now, in January, riders are officially reporting that they are able to hail a ride from a Model Y Robotaxi without anyone in the vehicle:

Tesla started testing this internally late last year and had several employees show that they were riding in the vehicle without anyone else there to intervene in case of an emergency.
Tesla has now expanded that program to the public. It is not active in the entire fleet, but there are a “few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors,” Ashok Elluswamy said:

Starting with a few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors, and the ratio will increase over time. https://t.co/ShMpZjefwB

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi program also operates in the California Bay Area, where the fleet is much larger, but Safety Monitors are placed in the driver’s seat and utilize Full Self-Driving, so it is essentially the same as an Uber driver using a Tesla with FSD.
In Austin, the removal of Safety Monitors marks a substantial achievement for Tesla moving forward. Now that it has enough confidence to remove Safety Monitors from Robotaxis altogether, there are nearly unlimited options for the company in terms of expansion.
While it is hoping to launch the ride-hailing service in more cities across the U.S. this year, this is a much larger development than expansion, at least for now, as it is the first time it is performing driverless rides in Robotaxi anywhere in the world for the public to enjoy.
Tesla has scheduled its Earnings Call for Q4 and Full Year 2025 for next Wednesday, January 28, at 5:30 p.m. EST, and investors are already preparing to get some answers from executives regarding a wide variety of topics.
The company accepts several questions from retail investors through the platform Say, which then allows shareholders to vote on the best questions.
Tesla does not answer anything regarding future product releases, but they are willing to shed light on current timelines, progress of certain projects, and other plans.
There are five questions that range over a variety of topics, including SpaceX, Full Self-Driving, Robotaxi, and Optimus, which are currently in the lead to be asked and potentially answered by Elon Musk and other Tesla executives:
- You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?
- Our Take – With a lot of speculation regarding an incoming SpaceX IPO, Tesla investors, especially long-term ones, should be able to benefit from an early opportunity to purchase shares. This has been discussed endlessly over the past year, and we must be getting close to it.
- When is FSD going to be 100% unsupervised?
- Our Take – Musk said today that this is essentially a solved problem, and it could be available in the U.S. by the end of this year.
- What is the current bottleneck to increase Robotaxi deployment & personal use unsupervised FSD? The safety/performance of the most recent models or people to monitor robots, robotaxis, in-car, or remotely? Or something else?
- Our Take – The bottleneck seems to be based on data, which Musk said Tesla needs 10 billion miles of data to achieve unsupervised FSD. Once that happens, regulatory issues will be what hold things up from moving forward.
- Regarding Optimus, could you share the current number of units deployed in Tesla factories and actively performing production tasks? What specific roles or operations are they handling, and how has their integration impacted factory efficiency or output?
- Our Take – Optimus is going to have a larger role in factories moving forward, and later this year, they will have larger responsibilities.
- Can you please tie purchased FSD to our owner accounts vs. locked to the car? This will help us enjoy it in any Tesla we drive/buy and reward us for hanging in so long, some of us since 2017.
- Our Take – This is a good one and should get us some additional information on the FSD transfer plans and Subscription-only model that Tesla will adopt soon.
Tesla will have its Earnings Call on Wednesday, January 28.
Elon Musk shared an incredible detail about Tesla Cybercab’s potential efficiency, as the company has hinted in the past that it could be one of the most affordable vehicles to operate from a per-mile basis.
ARK Invest released a report recently that shed some light on the potential incremental cost per mile of various Robotaxis that will be available on the market in the coming years.
The Cybercab, which is detailed for the year 2030, has an exceptionally low cost of operation, which is something Tesla revealed when it unveiled the vehicle a year and a half ago at the “We, Robot” event in Los Angeles.
Musk said on numerous occasions that Tesla plans to hit the $0.20 cents per mile mark with the Cybercab, describing a “clear path” to achieving that figure and emphasizing it is the “full considered” cost, which would include energy, maintenance, cleaning, depreciation, and insurance.
Probably true
— Elon Musk (@elonmusk) January 22, 2026
ARK’s report showed that the Cybercab would be roughly half the cost of the Waymo 6th Gen Robotaxi in 2030, as that would come in at around $0.40 per mile all in. Cybercab, at scale, would be at $0.20.

This would be a dramatic decrease in the cost of operation for Tesla, and the savings would then be passed on to customers who choose to utilize the ride-sharing service for their own transportation needs.
The U.S. average cost of new vehicle ownership is about $0.77 per mile, according to AAA. Meanwhile, Uber and Lyft rideshares often cost between $1 and $4 per mile, while Waymo can cost between $0.60 and $1 or more per mile, according to some estimates.
Tesla’s engineering has been the true driver of these cost efficiencies, and its focus on creating a vehicle that is as cost-effective to operate as possible is truly going to pay off as the vehicle begins to scale. Tesla wants to get the Cybercab to about 5.5-6 miles per kWh, which has been discussed with prototypes.
Additionally, fewer parts due to the umboxed manufacturing process, a lower initial cost, and eliminating the need to pay humans for their labor would also contribute to a cheaper operational cost overall. While aspirational, all of the ingredients for this to be a real goal are there.
It may take some time as Tesla needs to hammer the manufacturing processes, and Musk has said there will be growing pains early. This week, he said regarding the early production efforts:
“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
