The Sangnam J-9 (전투기 9; Jeontugi 9; Fighter (No.) 9) is a single-engine, variable-geometry fighter aircraft produced by the Sangnam Aircraft Design Bureau. Based on the Vanquarian MiG-23, it was a major step in advancing the PLAAF's capabilties, the main fighter of which up until that point was the MiG-21-derived J-7. The J-9 remains in service with the DPAAF today, even though it is slowly being replaced by the more advanced J-12.
