U.S. Intelligence Warns of China Theft Over Sale of F-35 Jets to Saudis

intelligence agencies have raised fresh concerns that the sale of F‑35 Lightning II fighter jets to Saudi Arabia could provide Beijing with new avenues to acquire sensitive American aerospace technology. A series of internal assessments, including a recent report from the Pentagon’s Defense Intelligence Agency (DIA), warn that China may seek to obtain classified design data and operational knowledge through espionage networks embedded in the Kingdom or by leveraging existing defence‑industry partnerships.The United States announced the potential transfer of up to 50 F‑35s to Saudi Arabia in early 2024, marking the largest single export of the fifth‑generation aircraft to a foreign customer. The deal, valued at more than $30 billion, has been portrayed by Washington as a means to bolster the Kingdom’s air‑defence capabilities amid regional tensions and to cement a strategic partnership that counters Iranian influence..

However, officials in the intelligence community say the commercial benefits are outweighed by the risk that the advanced stealth, sensor fusion and software architecture of the jet could be reverse‑engineered or illicitly copied.According to the DIA assessment, China has long pursued a “multi‑vector” approach to narrowing the technology gap with the United States, combining cyber‑intrusion, human intelligence collection and cooperative arrangements with allied states. The report cites a “significant probability” that Chinese operatives could gain access to F‑35 maintenance manuals, supply‑chain data and training curricula through Saudi personnel who will be stationed at U.S. bases for joint exercises and at the aircraft’s production facilities in Indiana, South Carolina and Texas..

The analysis also notes that Saudi Arabia’s own defence contractors have previously engaged Chinese firms on unrelated projects, creating a conduit for technical exchange.U.S. officials stress that the risk is not merely theoretical. In the past decade, Beijing has successfully obtained components of U.S..

weapon systems, most notably the F‑22 stealth fighter, through a combination of cyber‑theft and the recruitment of foreign nationals. The 2018 indictment of a former Lockheed Martin engineer for passing classified data to China highlighted the vulnerability of complex supply chains that span multiple continents. Intelligence officers argue that the F‑35, with its integrated software ecosystem and reliance on a global network of suppliers, presents an even larger target.The Department of Defense has responded by tightening export‑control protocols for the F‑35 program..

New safeguards include mandatory background checks for all foreign technicians, restricted access to the aircraft’s “core software” modules, and the establishment of a “digital enclave” that isolates sensitive code from external networks. Additionally, the United States plans to increase on‑site monitoring of Saudi personnel during joint training missions, employing both physical security measures and real‑time cyber‑surveillance tools.Saudi officials have dismissed the concerns as “unfounded” and have reiterated their commitment to safeguarding partner technology. In a statement to regional media, the Kingdom’s Minister of Defence said that Saudi Arabia has “robust counter‑intelligence capabilities” and that all personnel involved in the F‑35 program will undergo “stringent vetting” in line with U.S..

The minister also pointed to the long‑standing security cooperation between Riyadh and Washington, arguing that the partnership has already withstood “numerous external threats.”Critics in Washington argue that the assurances may not be sufficient. Members of the Senate Armed Services Committee have called for a comprehensive review of the sale, warning that the United States could inadvertently strengthen a geopolitical rival by facilitating the diffusion of its most advanced combat aircraft. In a recent hearing, a senior congressional aide warned that “once the technology leaves our shores, we lose control over its downstream use, and that includes the possibility of it ending up in the hands of adversaries.”The debate unfolds against a broader backdrop of U.S.–China rivalry that has intensified over trade, the Taiwan Strait and competing visions for global technology standards..

Analysts note that the F‑35 program already faces pressure from budget constraints and technical challenges, and that any compromise of its intellectual property could have ripple effects across the defence industrial base. A leak of critical design information could enable Chinese engineers to accelerate their own fifth‑generation fighter development, narrowing the gap that U.S. policymakers have long sought to maintain.Nevertheless, proponents of the sale argue that the strategic benefits outweigh the security risks..

They contend that a capable Saudi air force serves as a deterrent to Iran’s missile programmes and contributes to stability in the oil‑rich Gulf region, a cornerstone of U.S. Moreover, the deal is seen as a way to cement long‑term arms sales that fund further research and development for next‑generation platforms, including unmanned combat aerial vehicles and hypersonic weapons.The final decision on the F‑35 transfer is expected within weeks, as the Pentagon prepares to brief senior administration officials on the intelligence findings. If approved, the first aircraft are slated to arrive in Saudi Arabia by early 2025, followed by a phased training schedule for pilots and ground crews..

Should the concerns about Chinese espionage prove prescient, the United States may be compelled to revisit its export‑control framework and consider more restrictive measures for future sales of high‑technology weapon systems.In the meantime, the intelligence community continues to monitor Chinese activity across the region, focusing on cyber‑intrusion attempts targeting U.S. defence contractors and the recruitment of insiders within allied militaries. The DIA’s report underscores a broader strategic imperative: safeguarding the technological edge that underpins American military superiority, even as the United States seeks to maintain strong defence relationships with partners whose own security interests may intersect with those of its great‑power competitors..
