Builds and maintains F-35 fighter jets as the only company legally allowed to complete and deliver them anywhere in the world.
Lockheed Martin builds and sustains the F-35 fighter as the sole prime contractor, with every aircraft — whether destined for the U.S. Air Force, the Royal Air Force, or any of the nine partner nations — required to pass through one of only two classified assembly sites, Fort Worth or Cameri, where security-cleared technicians apply stealth coatings and validate radar signatures inside anechoic chambers that cannot legally be replicated anywhere else. Because those two facilities are the only points on earth where an F-35 can be legally completed, every delivery in the world flows through a bottleneck that cannot simply be expanded by spending more money — adding capacity means building new classified facilities, a process measured in years and subject to government approval. Once a nation takes delivery, its mechanics can only run diagnostics through ALIS, the proprietary logistics software Lockheed Martin controls, and its pilots train on F-35-specific simulators, so switching to a different aircraft would mean ripping out and replacing billions of dollars' worth of infrastructure built around this one jet. The single point of fragility in all of this is the U.S. State Department's export licence: if that authorisation is suspended, no completed aircraft can legally leave either facility, which would simultaneously halt partner-nation deliveries, freeze sustainment contracts, and stop software upgrade fees — because all three revenue streams share the same two classified exit points.
How does this company make money?
The company receives a payment from the customer government each time a completed F-35 is accepted at Fort Worth or Cameri. It also holds long-term sustainment contracts that cover spare parts and maintenance services across the aircraft's 30-plus-year life. Finally, it charges licensing fees whenever mission system software is upgraded and pushed out to the global fleet.
What makes this company hard to replace?
Once a nation fields F-35s, its mechanics can only run diagnostics and order spare parts through ALIS, the proprietary software the company controls. Pilots train on F-35-specific simulators installed at partner nation training centres, so switching aircraft would mean replacing that entire training infrastructure. On top of that, each customer has already invested heavily in weapons, data links, and ground equipment built to work specifically with the F-35, creating switching costs that run into the billions of dollars.
What limits this company?
The only places where an F-35 can be finished are Fort Worth and Cameri, because security rules ban those final steps from happening anywhere else. The number of stealth-coating bays and anechoic test chambers at those two sites sets a hard ceiling on how many jets can be completed each year. Building more capacity would mean constructing new classified facilities, which takes years and requires the same government approvals that already slow the programme.
What does this company depend on?
The company cannot build or deliver an F-35 without four things: engines from Pratt & Whitney, specifically the F135 model; classified stealth coating materials from specialty suppliers; valid export licences from the State Department's Directorate of Defense Trade Controls; and a workforce that holds the security clearances required to enter the anechoic test chambers and handle classified coating processes.
Who depends on this company?
The U.S. Air Force relies on F-35A deliveries to modernise its fighter fleet, and delays would leave older aircraft in service longer than planned. The Royal Air Force depends on the F-35B variant, which can land vertically, to operate from Queen Elizabeth-class carriers — without it, those carriers lose their main combat aircraft. NATO partner nations that have contracted F-35s for their own air force modernisation programmes fall behind schedule when deliveries are disrupted, weakening the shared communications and weapons systems that make NATO forces work together.
How does this company scale?
Software updates and changes to the mission systems can be pushed across the entire global F-35 fleet through a common avionics architecture, so improving the aircraft's capabilities costs roughly the same whether the fleet has 100 jets or 1,000. What does not scale easily is the physical production line: Fort Worth and Cameri have a fixed number of coating bays and test chambers, security clearance requirements prevent outsourcing those steps, and adding capacity requires building new classified facilities.
What external forces can significantly affect this company?
Each year, the U.S. Congress decides how many F-35s to fund, and partner nations make similar annual decisions, so procurement numbers can shift with political priorities. Changes to ITAR export control rules can block international deliveries entirely, regardless of what partner nations have contracted. Rising geopolitical tensions with China are also pushing allied nations to rethink how openly they commit to F-35 integration, which can slow or complicate orders.
Where is this company structurally vulnerable?
Every international delivery depends on an export licence issued by the State Department's Directorate of Defense Trade Controls. If those licences were suspended or restricted, no completed F-35 could legally leave Fort Worth or Cameri for any partner nation. That single event would simultaneously stop delivery payments, freeze the long-term sustainment contracts, and halt software upgrade fees, because all three income streams begin at the same two facilities the export licence authorises.
Supply Chain
Aerospace Supply Chain
The aerospace supply chain is governed by three root constraints that interact to produce extreme concentration, decades-long supplier lock-in, and a system where every component must be traceable from raw material to flight: certification requirements make every part a regulated article, product lifecycles measured in decades force suppliers to support platforms long after production ends, and integration complexity across millions of parts from thousands of suppliers creates coordination demands that few organizations can manage.
Defense Supply Chain
The defense supply chain is governed by three root constraints that interact to produce extreme supplier concentration, glacial production timelines, and a system where political decisions — not market demand — determine what gets built and how much: monopsony buyer structure means the government is typically the only customer, security classification requirements restrict who can manufacture, supply, and even know what is being produced, and production rate inflexibility means defense manufacturing runs at low volumes with specialized tooling where surge capacity barely exists because maintaining idle lines for contingencies has no commercial justification.
