Satellite images reveal AMCA undergoing crucial stealth testing in Hyderabad: Why is it significant?

India's ambitious Advanced Medium Combat Aircraft (AMCA) programme appears to have crossed another important development milestone, with satellite imagery revealing the presence of a full-scale engineering airframe at a specialised Radar Cross Section (RCS) measurement facility at Dundigal in Hyderabad. The airframe, which was first showcased publicly during Aero India 2025, has now been spotted at the facility where it is believed to be undergoing ground-based assessments linked to the aircraft's stealth performance. The development has attracted significant attention among defence observers, as stealth evaluation is considered one of the most critical stages in the development of a fifth-generation fighter aircraft.
