Washington aims to field two next-generation stealth fighters – the Air Force’s F-47 and the Navy’s F/A-XX – around the same time, but defence planners face a critical challenge: the capacity of the US aerospace industry to deliver on this ambitious goal.
Pentagon’s Ambition Meets Industrial Constraints
The US Air Force is developing the “Next Generation Air Dominance” fighter, known as the F-47 by analysts, while the US Navy is pursuing the F/A-XX, a future carrier-based fighter. Both are described as sixth-generation aircraft, designed to be stealthier than the F-35, highly connected, and capable of operating with unmanned drones.
This dual-track approach is intended as a demonstration of technological strength, positioning the US ahead of competitors like China and Russia. But, the underlying issue is a shrinking industrial base struggling to support two major programs simultaneously.
A Concentrated and Vulnerable Industry
Today, three large contractors dominate US combat aircraft production. The industry’s consolidation has reduced redundancy, creating a situation where even minor disruptions could have significant consequences. Dozens of smaller firms supply critical components like high-temperature alloys and hardened circuit boards, many of which come from limited sources.
These suppliers, some of which are financially vulnerable, are already operating near their capacity limits. Doubling output for two new fighter programs would require substantial investment and carries the risk of burnout.
The Human Factor
A key constraint is the availability of skilled workers. The aerospace workforce is aging, and recruitment lags demand. Engineers, coders, and technicians require security clearances, extensive training, and years of experience. These same professionals are also highly sought after by commercial tech companies offering higher salaries and more flexible careers.
The Air Force and Navy risk competing for the same limited pool of talent, driving up wages and potentially compromising quality. Even minor errors in construction, like sealing or wiring, can jeopardize the substantial investments in these advanced aircraft.
Potential Paths Forward
Defence planners are exploring strategies to mitigate these risks. One approach is to maximize commonality between the two aircraft, sharing subsystems where possible to reduce strain on unique resources. Another is to stagger the development schedules, allowing each program to peak at different times.
A slower, phased approach could prove more realistic, delivering aircraft more reliably, even if it means a less dramatic initial demonstration of capability. The Pentagon could also invest in expanding and strengthening the supplier base, supporting second-source development and long-term contracts.
What’s at Stake
The success of these programs has implications beyond US national security. Potential scenarios include pushing ahead with both fighters, merging requirements into a single design, or facing cuts due to budget constraints or delays. Each path carries consequences for allies, NATO’s deterrence, and the global arms market.
Frequently Asked Questions
What are the key features of a sixth-generation fighter?
Sixth-generation fighters are expected to include low observable design, the ability to team with unmanned drones, highly flexible sensor fusion, open software architectures, and potentially adaptive engines.
What are the three critical component areas identified as vulnerable?
The three areas identified as especially vulnerable are advanced materials, electronics and chips, and propulsion systems.
What is the biggest challenge to building these new fighters?
The biggest challenge is the capacity of the US aerospace workforce and supply chain to support two major programs simultaneously.
Given the complex interplay of technological advancement, industrial capacity, and budgetary realities, how will the US prioritize its investments in future air power?
