Beijing is ramping up production of the J-20 and launching the J-35A. An industrial and military strategy that could upend the global balance of air power by 2030.
In summary
China has reached a milestone in its military buildup. Analysis of satellite imagery and assessments by Western experts indicate that production of the Chengdu J-20 stealth fighter has now reached an estimated rate of between 100 and 120 aircraft per year. Meanwhile, the new Shenyang J-35A, the land-based version of a program originally intended for naval use, has confirmed that it has entered an advanced stage of development.
These two programs reflect a profound industrial transformation. Beijing seeks to build the world’s largest fleet of fifth-generation fighter jets. Several projections suggest a target of approximately 1,000 J-20 stealth fighters and several hundred J-35s by 2030.
Beyond the sheer number of aircraft, this strategy reflects a clear logic. China wants to reduce the U.S. technological advantage, strengthen its access-denial capabilities in the Asia-Pacific, and have a credible tool at its disposal in the event of a crisis involving Taiwan. This rise in power raises a central question: is the global air power balance shifting?
The Industrial Ramp-Up of J-20 Production
The increase in J-20 production is the most striking development. Introduced into operational service in 2017, this stealth aircraft is the first fifth-generation fighter developed by China.
Open-source estimates indicate that approximately 300 J-20s were in service by 2025, with annual production now ranging between 100 and 120 aircraft, compared to about 20 aircraft per year in the early 2020s. This growth illustrates a major shift in industrial scale.
This acceleration is driven by several industrial factors:
- The expansion of assembly lines
- The standardization of production
- The gradual maturation of the WS-10 and WS-15 domestic engines
- Improved manufacturing tolerances
China is now adopting an approach similar to that used for the American F-35: mass production to reduce unit costs and increase operational readiness.
The J-20 is no longer a technology demonstrator. It is becoming a central combat system in Chinese doctrine.
The Role of the J-20 in Chinese Military Strategy
The J-20 is designed as a heavy air superiority fighter. Its primary mission is to neutralize enemy command aircraft, tankers, and fighters at long range.
Its aerodynamic configuration prioritizes range and the carriage of long-range missiles. It is often compared to the American F-22, but with a different philosophy. China prioritizes engagement beyond visual range rather than close-range combat.
Its estimated characteristics include:
- A length of approximately 20.3 meters
- A wingspan of 12.9 meters
- A maximum speed close to Mach 2
- An internal bay for stealth missiles
Its AESA radar and distributed sensors are designed to enable networked warfare. The objective is clear: to integrate the J-20 into a comprehensive system comprising drones, satellites, and long-range missiles.
China is thus developing a so-called anti-access/area denial (A2/AD) architecture designed to complicate any foreign intervention in its strategic periphery.
The Development of the J-35A and the Logic of Operational Mass
The second pillar of this strategy rests on the J-35. This aircraft, developed by Shenyang Aircraft Corporation, is intended to complement the J-20.
Unlike the J-20, which remains a heavy fighter, the J-35 is designed for a more versatile role. It is often compared to the American F-35 in its design philosophy.
The program includes two versions:
- The naval J-35 for aircraft carriers
- The land-based J-35A for the air force
The J-35A is intended to rapidly increase the number of stealth fighters available. This approach responds to a simple reality: numbers matter just as much as technology in a high-intensity conflict.
Projections suggest approximately 300 J-35As by 2030, complementing the J-20 fleet.
This combination would give China the world’s largest stealth fleet.
The Industrial Transformation of China’s Military Aviation
This acceleration is not limited to aircraft. It reflects a profound transformation of China’s industrial sector.
For the past fifteen years, Beijing has been investing heavily in:
- Composite materials
- AESA radars
- High-thrust engines
- Onboard artificial intelligence
- Automated production
This strategy is part of the national industrial policy aimed at making China a major technological power.
The ability to produce more than 100 stealth fighters per year represents a critical threshold. Few countries possess such industrial capacity.
By way of comparison, the F-35s produced in the United States are destined for nearly 20 partner countries. Chinese production is intended almost exclusively for its own military.
This means that every aircraft produced directly strengthens national power.
The goal of 1,000 stealth fighters and its strategic significance
The stated goal of 1,000 fifth-generation aircraft constitutes a major strategic signal.
If this threshold is reached, China would have a fleet comparable to or larger than that of the United States in the Indo-Pacific region.
Several analyses estimate that this level would enable:
- A permanent presence across multiple theaters
- Strong resilience in the event of losses
- Constant pressure on enemy bases
- The ability to saturate enemy defenses
The goal is not merely quantitative. It is about achieving an operational critical mass.
In a scenario involving Taiwan, this fleet could enable continuous rotations of stealth aircraft, complicating the enemy’s defense.
China’s strategy thus reflects a logic of direct competition with the United States for regional air superiority.
The Geopolitical Impact on the Military Balance in the Asia-Pacific
This buildup is causing concern among several countries in the region.
Japan is accelerating the modernization of its F-35 fleet. South Korea is developing the KF-21. Australia is strengthening its cooperation with the United States.
This dynamic is fueling a technological race.
The increase in J-20s strengthens China’s ability to challenge the U.S. presence in the first island chain of the Pacific. This includes:
- Taiwan
- Okinawa
- The Philippines
- Guam
This development is gradually eroding the West’s qualitative advantage.
Some analysts believe that China could challenge U.S. air superiority in certain areas by the end of the decade.
This potential shift represents one of the most significant strategic changes since the end of the Cold War.
The Doctrinal Significance of China’s Rise
Beyond the numbers, this development reflects a doctrinal shift.
China is no longer seeking merely to defend its territory. It is developing a credible regional projection capability.
Stealth fighters enable:
- Preemptive strikes
- The neutralization of enemy radars
- Information dominance
- Integration with combat drones
The two-seat J-20S variant could notably serve as a command platform for loyal wingman drones.
This evolution brings Chinese doctrine closer to Western concepts of collaborative combat.
The major difference remains scale. China is banking on a combination of technology and mass.
The Western response to this acceleration
Faced with this dynamic, the United States is pursuing several responses:
- Modernization of the F-35 Block 4
- Development of the NGAD
- Cooperation with allies
- Investments in combat drones
Europe, for its part, is moving more slowly with the SCAF and GCAP programs.
The difference in industrial pace is becoming a central issue.
China is currently producing aircraft faster than Europeans are developing their future models.
This reality raises both an industrial and a military question: the ability to mass-produce is once again becoming a key factor in power.
The strategic message sent by Beijing
The proliferation of satellite imagery and public demonstrations is not insignificant.
Beijing is sending a clear signal:
China is now capable of competing technologically and industrially.
This message is aimed at several audiences:
- The United States
- Neighboring countries
- Domestic public opinion
- Strategic partners
The demonstration of industrial power has become a strategic communication tool.
Mass production is becoming an instrument of deterrence.
A new era of global air power competition
The progress of the J-20 and J-35 programs shows that air power competition among major powers is entering a new phase.
Technological superiority alone is no longer enough. Production capacity is once again becoming decisive.
China is following a clear logic:
Produce quickly. Produce in large quantities. Produce domestically.
This approach echoes the industrial strategies of the major powers of the 20th century.
It also shows that high-intensity warfare is once again becoming a defining scenario.
The question is no longer simply which aircraft is the most capable. The question has also become: who can produce the most, the fastest.
In this competition, China has just changed the rules of the game.
