How Stealthy Is China's J-36 Compared to America's F-22?

China's experimental J-36 aircraft presents a radical design, notably omitting vertical tail fins and adopting a double delta wing shape, powered by three engines. This starkly contrasts with the established F-22 Raptor of the United States. However, when it comes to verifiable stealth capabilities, the F-22 remains significantly ahead.

The F-22 has a long history of testing, production, and operational deployment. In contrast, the J-36 has not even been officially announced by Beijing, and assessments of its capabilities are largely based on photographic evidence and observed flight test modifications. The J-36's more futuristic design does not automatically translate to superior radar evasion. Crucial data on its radar cross-section, radar-absorbent materials, electronic emissions, and infrared signature are not publicly available.

Recent sightings of the J-36 reveal refinements in its air intake channels and aerodynamic profile. While reports suggest these changes could enhance its low-observable characteristics and airflow management, they lack official technical data from Chinese government or aviation industry sources. Therefore, the most accurate current assessment is that the J-36 represents a more radical design approach to stealth, whereas the F-22 offers more trustworthy stealth capabilities as a fully realized combat system.

The absence of vertical tail fins on the J-36 is a significant visual difference from the F-22's two large, canted vertical stabilizers. Eliminating vertical tails can reduce surfaces that reflect radar energy from certain angles. This tail-less design also allows for smoother fuselage lines, potentially directing radar reflections away from the source. While the F-22's tails add surfaces that require careful management to minimize radar reflections, they provide essential stability and control for lateral movement.

Euan Graham, a senior analyst at the Australian Strategic Policy Institute, noted that the J-36's new shape demonstrates boldness in Chinese aviation industry experimentation. He described it as a "very original design," regardless of its ultimate strengths or weaknesses. Despite the visual experimentation, experts interviewed by Reuters emphasize that external photos alone are insufficient to determine a stealth aircraft's true capabilities in terms of stealth, agility, speed, or avionics sophistication.
