China's J-20 Fleet Surpasses 500 Jets, Alarming US and Allies

China's rapid expansion of its J-20 stealth fighter fleet, estimated to exceed 500 aircraft, is causing growing unease among the United States and its allies. This build-up could significantly alter the military calculus in the Indo-Pacific region, challenging established power dynamics.

Analysts note that China's production rate for stealth fighters is unprecedented in recent decades. Joseph Duncan, writing for MigFlug, highlighted that China is not just building stealth jets but doing so at a pace unmatched by any nation in modern history. This capability means that sheer technological superiority of individual aircraft may no longer be sufficient if an adversary can field such a large number of advanced platforms.

China is not just building stealth jets; China is building them faster than any country has built modern fighter jets in decades.

While the exact number of J-20s in service remains undisclosed by China's Ministry of Defense, analysts estimate the figure by considering the number of air brigades equipped with the J-20, assuming approximately 28 aircraft per brigade, plus additional aircraft for training and tactical development. This estimated fleet of over 500 J-20s suggests China possesses the capacity to sustain air pressure during prolonged conflicts.

This development has prompted concern within the US military. In March 2022, General Kenneth Wilsbach, then Commander of Pacific Air Forces, acknowledged that US F-35s had encountered J-20s in the East China Sea. He expressed a degree of impression regarding the command and control systems associated with the J-20, though he noted it was too early to determine if China intended to use the J-20 as a multirole aircraft like the F-35 or as an air superiority fighter akin to the F-22.

We were relatively impressed with the command and control associated with the J-20.
