AMCA will also light up in enemy radar if it carries Brahmos. Stealth, good EW and autonomous operation are primary features of AMCA. AMCA will be tied up in anti-air operations and SEAD/DEAD missions.
Brahmos is suppose to have 800 km range in future. Even 400 km range is good enough taking in account how shallow is Pakistan. That is a good stand-off distance to successfully engage enemy.
Most of AMCA's strike operation will we be smart precision-guided mission like SEAD and DEAD operations where munitions like SAAW, PGM (Sudarshan, HSLD, Nag), NGARM. AMCA won't be used to target hardened targets. We even posses surface launched Brahmos if needed.
