近期，多架采用低可视度黄色涂装（俗称“黄皮”）的歼-20A隐身战斗机在中国多地频繁试飞，引发国内外广泛关注。这种“黄皮”涂装通常用于原型机或初期量产阶段，主要用于测试雷达反射截面、飞行性能及航电系统集成等关键指标。密集试飞表明，歼-20A可能正处于批量生产前的最后验证阶段，或正在进行新型子型号的技术升级测试。从战略角度看，此举释放出中国空军加速推进第五代战机列装进程的明确信号。一方面，说明国产WS-15发动机或相关航电系统的成熟度已达到新高度；另一方面，也反映出中国在高端航空制造领域具备了更强的自主可控能力。此外，密集试飞还可能为后续出口型隐身战机（如FC-31或潜在的歼-20衍生型号）积累技术数据和实战化经验。总体而言，黄皮歼-20A的密集试飞不仅体现了中国航空工业的技术自信，也彰显了其在大国竞争背景下加快军事现代化、提升空中战略威慑力的决心。
Recently, multiple J-20A stealth fighters in low-visibility yellow paint—commonly referred to as ‘yellow skin’—have been conducting frequent test flights across various locations in China, drawing significant domestic and international attention. This distinctive yellow livery is typically applied to prototype or early production aircraft, primarily used for testing key parameters such as radar cross-section, flight performance, and avionics integration. The surge in test flights suggests the J-20A may be in its final validation phase before mass production or undergoing technical upgrades for a new variant.Strategically, this activity signals China’s Air Force is accelerating the deployment of fifth-generation fighters. It indicates that domestically developed systems—such as the WS-15 engine or advanced avionics—have likely reached a new level of maturity. Moreover, it reflects China’s growing self-reliance and capability in high-end aerospace manufacturing. These intensive trials may also serve to gather critical data and operational experience for potential future export-oriented stealth fighters, such as the FC-31 or derivative models of the J-20.Overall, the密集 test flights of yellow-skinned J-20As not only demonstrate confidence in China’s aviation industry but also underscore its resolve to expedite military modernization and enhance strategic airpower amid great-power competition.
