Sixth generation is Dubbed as the "Next Generation Tactical Aircraft"/"Next Gen TACAIR", the USAF seeks a fighter with "enhanced capabilities in areas such as reach, persistence, survivability, net-centricity,
situational awareness, human-system integration and weapons effects," a November 4, 2010 presolicitation notice states. “The future system will have to counter adversaries equipped with next generation advanced electronic attack, sophisticated integrated air defense systems, passive detection, integrated self-protection,
directed energy weapons, and
cyber attack capabilities. It must be able to operate in the
anti-access/area-denial environment that will exist in the 2030–50 timeframe.”
The sixth-generation fighters are expected to use advanced engines such as
Adaptive Versatile Engine Technology to allow longer ranges and higher performance. Risk reduction began in 2012 so that engine development can start around 2020. An engine is to be ready when fighters are introduced by the Navy in 2028 and the Air Force in 2032.
And Most important is the Self Healing capability.
HAL/DRDO is working on self-Healing capability for AMCA.
