China has revealed two previously unseen tailless stealth combat aircraft designs within 24 hours, marking a significant step in its next-generation fighter program.
Both aircraft are currently undergoing flight testing, and imagery of these advanced jets has surfaced on social media, drawing significant attention.
The designs are believed to come from two rival Chinese aircraft manufacturers: Chengdu Aircraft Corporation (CAC) and Shenyang Aircraft Corporation (SAC).
The first aircraft, a larger diamond-shaped tailless jet, appeared in public on December 26, 2024, coinciding with the 13th anniversary of the Chengdu J-20’s first public appearance and the birthday of Mao Zedong.
Hours later, a smaller tailless design, attributed to Shenyang, was seen in photos and videos. Both jets feature a lack of traditional tail surfaces, a design choice that enhances their stealth capabilities by reducing their radar cross-section.

The larger aircraft from Chengdu is believed to have a three-engine powerplant, while the Shenyang design features a twin-engine setup, indicating a smaller size.
The Chengdu jet also has a modified diamond-delta wing shape, with extended “chines” at the wing roots, while the Shenyang design features a more angular, lambda wing shape with triangular extensions at the trailing edges.

Though the exact roles of the new jets are unclear, initial reports suggest that the Chengdu design could be part of the JH-XX program, a next-generation tactical fighter-bomber intended for regional operations. This aircraft may focus on speed and stealth, providing a versatile platform for air-to-air and air-to-ground missions.
The Shenyang jet is likely a fighter, possibly designed for air superiority, though it remains unclear whether it will be crewed or operated as a drone or optionally-crewed platform.
Both designs lack vertical and horizontal tail surfaces, following a trend in China’s aerospace industry to develop tailless aircraft.
Tailless designs offer advantages in terms of reduced radar signatures, improved aerodynamic performance, and greater internal space for fuel and weapons. These features are especially important for enhancing the aircraft’s range and combat persistence in the Asia-Pacific region.
The two aircraft have reportedly entered flight testing, with some unconfirmed reports indicating that the Shenyang jet made its first flight on December 20, 2024. However, there has been no official confirmation from Chinese authorities about the designs or their intended roles.
The release of these images appears to be part of a deliberate strategy, as the two aircraft were revealed together, creating maximum impact on the anniversary of the J-20’s debut.
The emergence of these two advanced aircraft comes as the US Air Force is also pursuing its own Next-Generation Air Dominance (NGAD) initiative, which includes the development of a sixth-generation stealth fighter. Experts such as Andreas Rupprecht, a Chinese aerospace observer, have suggested that these new Chinese designs are part of a larger effort to develop a “system of systems” approach to future air combat, integrating manned fighters with unmanned platforms and advanced sensors.
Although the exact nature of these new Chinese aircraft remains uncertain, they are clearly part of China’s broader strategy to modernize its air force and maintain a technological edge in regional air combat. The development of these next-generation jets underscores China’s commitment to advancing its military aviation capabilities and positions the country as a major player in the future of air combat. As more details emerge, both China’s military rivals and its allies will be closely watching the evolution of these aircraft and their potential impact on regional security.
