Fifth-Generation Aircrafts:


Enhanced Agility - High Survivability - Superior Stealth Technology

By M. Ahsan



Fifth-generation aircrafts are classified as most advanced jet fighters. They incorporate highly advanced technology, with stealth and multirole capabilities, high-performance mechanical structure, low probability of intercept radar (LPIR), sophisticated avionics features, and highly advanced software and integrated computer systems capable of networking with other elements within the battlespace for situation awareness.

At present, only four countries (US, Russia, China and Japan) have successfully flight tested the fifth-generation fighter jets, while India and Turkey are in the development phase of acquiring their own next generation fighters.

The five most advanced stealth jet fighters that have touched the sky include, American Lockheed Martin F-22 Raptor and Lockheed Martin F-35 (A/B/C variants) Lightning II, Russian Sukhoi PAK FA (T-50), Chinese Chengdu J-20, and Japanese Mitsubishi X-2 Shinshin.
