变“烈马”为“千里马” 解锁未来空中作战行动尖刀力量 | 歼20首飞15周年

Core Viewpoint - The J-20 stealth fighter jet, China's first, marks its 15th anniversary since its maiden flight on January 11, 2011, symbolizing the transition of the Chinese Air Force into the "stealth era" and has evolved into a core force for national air defense [1]. Group 1: Development and Training - Over the past 15 years, the J-20 has transitioned from technical validation to practical combat training, evolving into a key component of national defense [1]. - Recent training exercises have involved mixed formations of J-20s with J-16 and J-10C fighters, testing new tactical methods and adapting to future battlefield dynamics [5][6]. - The training approach has undergone significant changes, utilizing a closed-loop system of research, training, evaluation, and modification to enhance realism and effectiveness [8]. Group 2: Stealth Capabilities - The J-20's design contributes significantly to its stealth capabilities, with its shape accounting for 80% to 90% of its radar evasion effectiveness [14][16]. - The aircraft features an "S" shaped air intake designed to obscure the rear engine from radar detection, along with radar-absorbing materials to minimize reflections [16]. - The unique canard layout of the J-20 enhances wing lift, contributing to its overall performance [19]. Group 3: Technological Advancements - The J-20 has undergone various upgrades, resulting in the development of variants such as the J-20A and J-20S, which enhance its operational capabilities [22][30]. - The J-20A variant is designed for supersonic flight, featuring a smoother cockpit design that reduces drag and improves performance [24]. - The J-20S, a dual-seat version, allows for advanced tactical command and coordination with unmanned systems, enhancing its operational versatility [30][31].
