The Chengdu F-7/J-7 is a Chinese MiG-21-derived single-engine fighter family built through Shenyang, Chengdu, and Guizhou production lines and exported in multiple F-7 variants. The family includes Sri Lankan F-7 and F-7GS aircraft documented in the 1983 Sri Lankan Civil War, Nigeria's F-7NI Airguard variant, and Myanmar Air Force F-7 debris documented by Myanmar Witness during the 2021 Myanmar Civil War.
Sri Lanka Air Force No. 5 Fighter Squadron operated Chinese-built F-7 aircraft and reported more than 600 air-interdiction sorties and more than 170 combat air patrol missions during the final government campaign against the LTTE.
Myanmar Witness identified debris from a Myanmar Air Force Chengdu F-7 after a 10 June 2025 crash at Sa Par Sayt village in Pale Township, Sagaing Region, during fighting around Kant Daung police station and reported airstrike activity; the cause of the crash remained disputed.
J-7 is the domestic Chinese designation, while F-7 is the export designation used across many country-specific variants and FT-7 trainer derivatives.
| Variant | Configuration | Designation notes |
|---|---|---|
 | Nigerian export variant | Nigeria ordered 12 F-7NI single-seat fighters and three FT-7NI trainers from China; the linked catalog page covers the Nigerian variant and its Boko Haram conflict use. Sources: Nigeria's F-7Ni Airguards returns from maintenance in China |
| FT-7 | Two-seat export trainer family | Nigerian reporting distinguishes FT-7NI dual-seat trainers from F-7NI single-seat fighters. Sources: Nigeria's F-7Ni Airguards returns from maintenance in China |

The F-7/J-7 family is best read alongside its Soviet MiG-21 predecessor and country-specific export branches.

 | Soviet fighter predecessor | Airforce Technology describes the J-7/F-7 as a Chinese licence-built version of the Soviet MiG-21, making the MiG-21 page useful lineage context for the Chinese family. Sources: J-7 / F-7 Fighter Aircraft, China |
| Nigerian export fighter variant | The F-7NI Airguard is Nigeria's export variant of the Chengdu F-7/J-7 family and is documented separately because its Boko Haram conflict-use evidence is Nigeria-specific. Sources: Nigeria's F-7Ni Airguards returns from maintenance in China, Chengdu F-7NI |
The Chinese J-7/F-7 family developed from the MiG-21 lineage and later generated multiple export F-7 variants.
