The F-35 is America’s top 5th-generation stealth fighter, but it faces growing concerns over reliability, security, and safety. The discovery of Chinese-made parts in the F-35 raises concerns about supply chain security and quality control. China’s sanctions on U.S. defence firms, like Lockheed Martin, have added pressure to the troubled programme.
These developments highlight the F-35’s vulnerabilities and the risks of relying on complex global supply chains. The Pentagon is working to keep operations running despite these mounting challenges. The fighter’s triple crash rate has raised fresh concerns about pilot safety and design flaws.
Supply chain issues and persistent software problems continue to draw criticism from experts and lawmakers. This article examines how China’s sanctions impact the F-35 Fighter Program and its future prospects.

Chinese Sanctions: A Threat to Supply Chain Security
One of the primary concerns affecting the F35 program is supply chain security. The F-35 has been found to contain components sourced from Chinese manufacturers, including magnets in the turbomachine pumps. This discovery led to a temporary suspension of F-35 deliveries, as the Pentagon scrambled to ensure compliance with U.S. national security regulations.
Although deliveries resumed after assurances that new batches of F-35s would no longer include Chinese-made parts, the issue brought to light deeper concerns about reliance on foreign supply chains.
China’s sanctions on Lockheed Martin, the manufacturer of the F-35, have exacerbated these concerns. China’s sanctions: The F-35 Fighter Program faces critical challenges, as Lockheed Martin’s director for the Asia-Pacific region, David Sutton, has been placed on China’s sanctions list, restricting the company’s access to crucial funds and parts from Chinese sources.
Such vulnerabilities within the supply chain raise concerns about the long-term sustainability of the fighter jet, an aircraft that is so essential to U.S. and allied defence strategies.
Rising Crash Rate: Safety Under Scrutiny
Another major challenge facing the F35 program is the alarming increase in the aircraft’s crash rates. Since October 2020, the crash rate of the F-35 has tripled, with seven incidents reported, including a recent crash at Kirtland Air Force Base in May 2024. China’s sanctions: The F-35 Fighter Program faces critical challenges not only in terms of supply chain reliability but also in safety and performance, as these crashes have diminished confidence in the aircraft’s operational capabilities.
The F-35’s development and deployment are critical for the U.S. military, but the recent surge in accidents has triggered internal reviews. The aircraft is equipped with cutting-edge technology and is touted as one of the most advanced combat systems in the world.
However, the rising crash rate suggests that either mechanical or operational issues are undermining its reputation. For an aircraft that costs billions to develop and produce, the Pentagon must address this issue swiftly.
The Impact of Sanctions on Lockheed Martin
China’s sanctions will have significant implications for Lockheed Martin’s overall F35 program. The sanctions specifically target Lockheed’s operations in the Asia-Pacific region, a critical market for the company. Without access to funds or parts from China, Lockheed Martin is facing additional hurdles in maintaining the production flow of the F-35. China’s sanctions:The F-35 Fighter Program faces critical challenges in securing alternative suppliers and ensuring that the aircraft’s components meet stringent national security standards.
Moreover, these sanctions complicate Lockheed’s ability to navigate an already complex global supply chain. Military aircraft like the F-35 rely on components from a wide network of suppliers across the globe. Lockheed Martin must now restructure its supply chain to exclude Chinese components entirely, which could potentially increase production costs and delay timelines.
Software and Performance Issues
China’s sanctions, in addition to supply chain and crash concerns, have come to the forefront: The F-35 Fighter Program faces critical challenges in its software development. The F-35’s software is highly complex, managing everything from flight controls to weapon systems. However, the software has been the subject of consistent criticism, particularly for stability issues and untested capabilities. The slow rollout of updates exacerbates these software challenges, further impairing the program’s operational readiness.
Reports have highlighted the software’s incapacity to seamlessly integrate with other military systems, a crucial aspect for joint operations. If the F-35 is to maintain its role as the backbone of the U.S. and allied air forces, addressing these software issues is paramount. Given the global nature of the F35 program and the fact that many countries depend on aircraft for national defence, these delays and inconsistencies could have far-reaching consequences.
Pentagon’s Response: Addressing the Ejection Seat Concern
In response to mounting concerns, the Pentagon has made efforts to ensure that safety remains a priority for the F35 program. One notable decision was the choice not to replace the ejection seats with American-made alternatives, opting instead to retain the British-made ejection system. While some critics have questioned this decision, it demonstrates the complexity of the F-35’s global supply chain.
By retaining the British-made ejection system, the Pentagon ensures that pilots will continue to rely on a proven safety mechanism. China’s sanctions:The F-35 Fighter Program faces critical challenges in securing alternative components, but this decision emphasises that it requires careful deliberation when selecting suppliers, especially when it comes to pilot safety.
The Future of the F-35 Program
While the F-35 remains a cornerstone of U.S. air power, China’s sanctions mean the F-35 Fighter Program faces critical challenges that could impact its future. Issues surrounding the use of Chinese-made parts, rising crash rates, software development setbacks, and the impact of sanctions on Lockheed Martin all contribute to a programme that requires close monitoring and adjustments.

As global tensions grow, keeping the F-35 reliable and secure is more important than ever. The Pentagon and Lockheed Martin must cooperate closely to tackle these challenges directly. China’s sanctions add complexity to an already troubling situation for the fighter program.
The F-35’s future depends on finding alternative suppliers and ensuring stable production. Improving software performance will be vital to enhance the jet’s operational reliability. Restoring confidence in the aircraft’s safety is key to its long-term success.
Conclusion
China’s sanctions: The F-35 Fighter Program faces critical challenges across multiple areas, from supply chain vulnerabilities to operational safety. As one of the most advanced fighter jets in the world, the F-35 must overcome these hurdles to maintain its strategic importance. The Pentagon’s decisions, coupled with Lockheed Martin’s ability to navigate these sanctions, will determine the program’s long-term success.
