The J-8 (Chinese code name: J-8, English: Shenyang J-8 or F-8, NATO code name: Finback [10], translation: Finback) fighter jet is a dual-engine fighter designed and developed by China in the 1960s. High-altitude, high-speed interceptor fighter.
The J-8 is one of the main fighter types of the Chinese Air Force and Naval Aviation from the 1980s to the early 21st century, and is gradually being retired.
There are 9 types of J-8: J-8, J-8 Daytime Type, J-8 A (J-8 I), J-8 B (J-8 II), J-8 C, J-8 D, J-8 F, J-8 H, JJ Eight（J-8 Reconnaissance）。
