Beijing ramps up sixth-generation fighter jet programs to counter U.S. airdominance
ISLAMABAD- China’s advanced stealth fighter development took a significantstep forward this week as the Shenyang J-50 sixth-generation aircraftreportedly conducted another successful test flight. The prototype, spottedat an undisclosed location, represents one of two sixth-generation fighterprograms currently being developed in parallel—alongside the Chengdu J-36.With increasing urgency, Beijing appears determined to fast-track bothaircraft toward operational readiness.
The J-50, which was first seen in late 2024, has drawn considerableattention for its futuristic design. Featuring a tailless delta-lambda wingconfiguration, thrust-vectoring twin engines, and integrated stealthcapabilities, the aircraft is expected to serve as an air superiorityplatform. Defense analysts suggest it may be suited for naval deploymentdue to its compact and agile form. Imagery released in mid-2025 confirmscontinued low-altitude and mid-range flight testing, with emphasis onmaneuverability and radar evasion.
Simultaneously, the Chengdu J-36 continues its own testing regime. TheJ-36, first unveiled during a test flight in December 2024, features alarge diamond-shaped tailless wing and triple-engine configuration. It isbelieved to be a multi-role platform with long-range strike capabilities.Recent leaks show the aircraft with a spacious fuselage, hinting at a largeinternal weapons bay, possibly enabling deployment of hypersonic orstand-off munitions. The design also includes dorsal engine inlets, reducedinfrared signature, and side-by-side cockpit seating.
Both aircraft are seen as China’s direct response to the United States’Next-Generation Air Dominance (NGAD) program. The development of twoseparate sixth-generation fighters simultaneously, from different designbureaus, mirrors the strategy used during the fifth-generation competitionbetween the J-20 and FC-31. In this case, the J-50 could serve as a highlymaneuverable fighter with battlefield air superiority in mind, while theJ-36 may act as a strategic strike and drone-command platform.

Chinese engineers have also reportedly introduced revolutionary coolingtechnologies aimed at reducing engine turbine temperatures more rapidlythan previous designs. This breakthrough could extend operational range,engine life, and stealth characteristics—key requirements forsixth-generation platforms. According to recent coverage from Chinese andinternational defense media, these cooling systems may allow the aircraftto fly longer at supersonic speeds without detection.
While both programs remain in the testing phase, the frequency of flighttrials and visual sightings suggests accelerated development. The urgencyis likely driven by strategic calculations, particularly as the U.S., UK,and Japan move closer to fielding next-generation stealth aircraft of theirown. Analysts note that China’s leadership has directed itsmilitary-industrial complex to prepare these aircraft “as soon aspossible,” reflecting growing competition in the aerospace defense domain.
In the near future, China could be the only nation aside from the UnitedStates operating two different sixth-generation fighter aircraft. Withongoing test flights and steady technological progress, the J-50 and J-36are poised to redefine the balance of airpower in East Asia and beyond.
