While traditional aerospace companies were counting money on government orders, SpaceX used commercial thinking to break industry barriers – reducing the launch cost per kilogram from US$18,000 to US$1,500. This is not a technological miracle, but a cost strangulation war that has been planned for twenty years.
01
Breaking the constraints of traditional aerospace costs
Before the emergence of SpaceX, out-of-control costs in the U.S. aerospace industry had long been the norm. United Launch Alliance’s (ULA) “cost-plus” model makes each Delta IV rocket cost up to $400 million, and contractors are still wrangling over which metal to use for welding fuel tanks – titanium alloy or aluminum alloy, robotic arms or manual labor. Behind these choices is the game of supplier interests. When Musk tried to buy a Russian rocket, he encountered not only price humiliation, but also exposed the traditional aerospace industry for what it is: a gold-eating beast created by the confluence of geopolitics, the military-industrial complex, and the bureaucracy.
(Picture: Musk has traveled to Russia many times to negotiate the purchase of rockets modified from decommissioned intercontinental missiles to implement the “Mars Oasis” plan)
SpaceX’s breaking point lies precisely in its “industry amateur” status. Musk does not have the mindset brought by his aerospace background, but instead moved Silicon Valley’s “disruptive innovation” logic to the aerospace field:
① Cost reshaping:
Discover traditional rockets
80% of parts cost comes from “aerospace grade” certification
process rather than actual functional requirements.
② Establish an independent manufacturing system: After Russia stopped supplying RD-180 and RD-181 rocket engines to the United States, SpaceX decided to establish a vertically integrated manufacturing system and independently develop and produce rocket engines.
③Risk tolerance: learn from the “
Quick trial and error
” method to break through the “zero fault tolerance” culture of the aerospace industry.

It was this kind of cross-border thinking that allowed Musk to dare to propose the idea of a “recyclable rocket” in 2004. At that time, NASA engineers privately commented that this idea was “more ridiculous than a perpetual motion machine.”

How to significantly reduce launch costs
1. “Civilization” of technology
SpaceX has torn apart the veil of traditional aerospace’s “pursuit of perfection regardless of cost.” Its Merlin engine uses the casting process of the automotive industry, allowing a 0.5% defect rate, while the quality inspection standards of the Russian RD-180 engine result in a 30% scrap rate. This “good enough” philosophy is reflected in:
① Starlink satellites: Design life is 5 years. Through mass production, the cost of a single satellite is reduced to 1/10 of traditional satellites.
②Stainless steel starship: use US$2,500 per ton
30X stainless steel
Replaces $30,000 in carbon fiber and withstands higher combustion temperatures.

③Software-defined rocket: passed
Flight control system compensates for lack of hardware accuracy
, reducing machining costs by 50%.
2. Changes in manufacturing methods
In ULA’s factory, fuel tank welding requires NASA-certified technicians to operate special equipment worth tens of millions of dollars; while SpaceX workers use plate rolling machines modified from the shipbuilding industry to roll stainless steel into rocket bodies, reducing the cost by 200 times. Specific measures include:
①Tesla manufacturing crossover: Tesla’s giant
Die casting machine
Transformed into rocket shell forming equipment.
②
3D printing:
laser printing technology
24 hours non-stop manufacturing
engine combustion chamber
, eliminating traditional turning technology.

③Modular design subversion:
80% of Falcon 9 parts are common to Falcon Heavy
, reusing designs saves $1.5 billion in R&D expenses.
3. Systemic cost reconstruction
While traditional aerospace companies are still optimizing individual links, SpaceX has rebuilt the entire value network:
①Transmission frequency revolution:
134 launches in 2024
The resulting scale effect reduces the marginal cost of each launch by 12%.
②Starchain ecological feedback: use
5.5 million subscribers
The cash flow supports rocket iteration and breaks dependence on government orders.

③ Rail economic closed loop:
On-orbit filling technology
It will reduce the cost of deep space missions by 90% and open up the possibility of commercializing lunar bases.

How SpaceX is changing the aerospace industry
SpaceX’s real disruption lies in reconstructing the essential attributes of spaceflight.
While ULA was still preparing 3,000 pages of technical documentation for each military launch, Musk had turned the rocket into a “space cargo truck”:

In 2006, Boeing and Lockheed Martin jointly established ULA)
① Break the price monopoly:
Low-Earth orbit launch fee per kilogram dropped from US$18,000 to US$1,500
, redefining industry pricing standards.
②Become an industry standard:
Falcon 9 rocket
go through
25 successful reuses
, proved its reliability and forced insurance companies to reduce premiums by 40%.
③Have the right to speak in the supply chain: SpaceX in turbine pumps, etc.
Independent research and development on key technologies
It breaks the monopoly of traditional suppliers and prompts second-tier suppliers to reduce prices.
The chain reaction triggered by this change forced Europe to accelerate the research and development process of the Ariane 6 rocket; at the same time, NASA was engaged in a fierce debate within NASA about the SLS project – which not only consumes a huge budget of US$3-4 billion per year, but also costs as much as US$2 billion for a single launch. But SpaceX has already built a deeper moat – the frequency band and orbital resources occupied by Starlink, the 100-ton capacity of the Starship, and the infrastructure layout for on-orbit refueling. These factors together constitute the “Space Maginot Line of Defense” in the new era.

On November 16, the SLS rocket successfully made its first flight)
Summarize
From being humiliated by Russia to the Starship base, SpaceX has spent twenty years proving a business truth: on a steep enough cost curve, any technological miracle will become a replicable industrial product. When the Falcon 9 was recovered and landed for the 20th time, it carried not only rocket components in the physical sense, but also the code for the entire aerospace industry to transition from “privilege economy” to “economy of scale.” This cost revolution has no end – as Musk said when the Starship was successfully recovered for the first time: “Now, we finally have the key to the solar system.”
