Indian Air Force's EMB-145 airborne early warning and control (AEW&C) system aircraft has made its maiden flight in Brazil after structural and aerodynamic modifications were completed by the Brazilian company Embraer.
The EMB-145I Airborne Warning and Control System (AEW&C) has been modified with an in-flight refueling system, SATCOM. Its reinforced airframe has been designed to accommodate a fixed, S-band, dual-sided Active Array Antenna Unit (AESA radar) mounted on top of the fuselage.
The Active Array Antenna Unit (AAAU) has been developed by the Defence Research & Development Organisation's (DRDO) CABS (Centre for Airborne Systems). The S-band AESA radar will provide 270 degree coverage of the airspace and will have detection range of around 350km against fighter sized aircraft.
Air-refueling by the IAF's IL-78 will allow the Indian EMB-145I Airborne Warning and Control System (AEW&C) to have an endurance of 9 hours.
