CHENGDU-<\/strong> China is rapidly increasing its fighter aircraft production capacity, focusing on advanced stealth platforms such as the J-20<\/a> and J-35<\/a>. Satellite-based analysis indicates a significant rise in manufacturing infrastructure and output potential.<\/p>\n\n\n\n

Chengdu, Shenyang, and Jingdezhen are key aerospace hubs supporting this expansion, enabling higher production of fifth-generation fighters and military aircraft for the People\u2019s Liberation Army.<\/p>\n\n\n\n

China Increases J-20 and J-35 Production Capacity<\/h2>\n\n\n\n

China is accelerating its military aviation growth through large-scale investments in manufacturing and testing infrastructure led by the Aviation Industry Corporation of China (AVIC).<\/p>\n\n\n\n

This expansion reflects a long-term strategy to increase both fleet size and combat capability.<\/p>\n\n\n\n

According to Flight Global<\/a>, the analysis is based on commercially available satellite imagery assessed by J. Michael Dahm, a senior fellow at the Mitchell Institute for Aerospace Studies.<\/p>\n\n\n\n

His findings, presented at the 2026 Air & Space Forces Association Warfare Symposium, indicate that China\u2019s inventory of fighter and attack aircraft will grow significantly over the next five years.<\/p>\n\n\n\n

The use of commercial satellite data, including imagery from Planet Labs, highlights a shift in how military developments are monitored.<\/p>\n\n\n\n

Open-source intelligence now plays a critical role in defence analysis, with similar imagery previously used to track Russian troop movements and more recently to reveal US military positions in the Middle East.<\/p>\n\n\n\n

Expansion of Core Production Facilities<\/h2>\n\n\n\n

Chengdu J-20 Manufacturing Complex<\/h4>\n\n\n\n

The Chengdu facility remains central to China\u2019s fifth-generation fighter production. Since 2021, approximately 278,700 square metres of additional manufacturing space have been added, bringing the site to five active production lines.<\/p>\n\n\n\n

Estimates suggest the annual output of the J-20 ranges between 100 and 120 aircraft. The platform, which has been operational for over a decade, is designed to rival advanced Western air superiority fighters.<\/p>\n\n\n\n

Recent satellite imagery also shows around 20 hectares of cleared land near the plant, previously occupied by Sichuan University. This space may support further expansion or future sixth-generation aircraft production.<\/p>\n\n\n\n

Shenyang Aircraft Production Hub<\/h4>\n\n\n\n

Shenyang is emerging as a major centre for next-generation fighter assembly. A new facility under development includes over 370,000 square metres of manufacturing space and a 3,660-metre runway.<\/p>\n\n\n\n

This site is expected to produce the J-35 and J-35A stealth fighters. The naval variant is being developed for carrier-based operations, including electromagnetic catapult launches from the CNS Fujian, while the land-based variant will serve the air force.<\/p>\n\n\n\n

Existing production lines in Shenyang continue to deliver fourth-generation aircraft such as the J-15 and J-16.<\/p>\n\n\n\n

Footage of these operations was previously shown in a state media documentary ahead of China\u2019s 2025 military parade.<\/p>\n\n\n\n

Changhe Helicopter Manufacturing Expansion<\/h4>\n\n\n\n

The Changhe facility in Jingdezhen is undergoing a 93,000 square metre expansion, increasing its capacity by approximately 30 percent.<\/p>\n\n\n\n

This site produces a range of military helicopters, including attack and heavy-lift transport platforms.<\/p>\n\n\n\n

Production Scale and Global Comparison<\/h2>\n\n\n\n

China\u2019s combined infrastructure expansion across its major aerospace sites exceeds 743,000 square metres, equivalent to roughly 8 million square feet. This surpasses the total size of the F-35 manufacturing complex in Fort Worth, Texas.<\/p>\n\n\n\n

Dahm estimates that AVIC could achieve an annual production capacity of 300 to 400 fighter aircraft, including both fourth and fifth-generation models. Even with partial utilisation, output is expected to reach at least 250 aircraft per year.<\/p>\n\n\n\n

In comparison, the United States produces approximately 156 F-35 fighters annually. Additional production includes up to 48 F-16 Block 70\/72 aircraft per year, with around 16 delivered annually in recent years, and 24 F-15EX fighters.<\/p>\n\n\n\n

In Europe, France delivered 26 Rafale jets in 2025, with plans to increase output to 44 per year.<\/p>\n\n\n\n

While Western manufacturers maintain advantages in technology and systems integration, China\u2019s strategy emphasises scale. High production volumes provide operational flexibility and sustained force generation.<\/p>\n\n\n\n

Lockheed Martin chief executive James Taiclet has stated that the J-20 is not equivalent to the F-35 in capability, reinforcing the view that the United States retains a qualitative edge despite China\u2019s quantitative gains.<\/p>\n\n\n\n

Development of Next-Generation Aircraft<\/h2>\n\n\n\n

China is also advancing experimental fighter programmes. New aircraft, including the J-36 and the smaller J-50, have been observed during flight testing in Chengdu and Shenyang.<\/p>\n\n\n\n

The J-50, also referred to as J-XDS, reappeared in March 2026, indicating continued development.<\/p>\n\n\n\n

These aircraft feature advanced designs such as tailless configurations and possible thrust vectoring capabilities.<\/p>\n\n\n\n

US Air Force General Kenneth Wilsbach has indicated that these platforms are likely intended for air superiority roles.<\/p>\n\n\n\n

They are broadly comparable to sixth-generation programmes under development in the United States, including the F-47<\/a> and the Navy\u2019s F\/A-XX.<\/p>\n\n\n\n

Expansion of Test Infrastructure<\/h2>\n\n\n\n

A remote test facility in Xinjiang, often described as \u201cChina\u2019s Area 51\u201d, has undergone rapid expansion.<\/p>\n\n\n\n

Satellite imagery shows the addition of 5,570 square metres of hangar space and over 27,800 square metres of new facilities within a year.<\/p>\n\n\n\n

In 2025, a J-50 aircraft was observed parked openly at this base. Analysts suggest this visibility may have been intentional, reflecting strategic signalling rather than operational oversight.<\/p>\n\n\n\n

Strategic Implications for Global Air Power<\/h2>\n\n\n\n

China\u2019s growing aircraft production capacity supports a broader military strategy focused on both regional readiness and global reach. Increased output enables faster fleet modernisation and sustained operational capability.<\/p>\n\n\n\n

One key focus remains Taiwan. Military planners have identified potential scenarios ranging from a prolonged blockade to a direct cross-strait operation.<\/p>\n\n\n\n

The so-called 2027 \u201cDavidson Window\u201d, named after Admiral Philip Davidson, marks a timeline by which China is expected to be prepared for such an operation. US officials have stated that Chinese forces are actively rehearsing related scenarios.<\/p>\n\n\n\n

Beyond regional considerations, China\u2019s expanding air power may enable greater global presence.<\/p>\n\n\n\n

Analysts predict that Chinese air assets will increasingly operate in regions beyond East Asia, challenging existing power structures.<\/p>\n\n\n\n

China may also use its increased production capacity to support export markets, strengthening its position in the global defence industry.<\/p>\n\n\n\n

At the same time, ongoing conflicts such as the US and Israel air campaign involving Iran demonstrate both the strengths and limitations of air power. These developments provide real-world context for evaluating the effectiveness of large-scale air capabilities.<\/p>\n\n\n\n
