Could you confirm if JF-17 is already upgrading on the following below?
-Greater use of composite materials in the airframe to decrease weight and increase thrust-to-weight ratio.
-Internal Infra-Red Search and Track (IRST) system, possibly the Type Hongguang-I Electro-optical Radar developed by Sichuan Changhong Electric Appliance Corporation (currently the IRST must be carried externally).
- More powerful engine, potential options include the Chinese WS-13 Tianshan and Russian RD-93B turbofans, giving 10% greater thrust than the current RD-93.
-Minor airframe modifications to reduce the aircraft's radar cross-section by adding stealthy features.
