Embraer has delivered to the Brazilian Air Force (FAB) its fifth EMB-145 AEW&C aircraft, upgraded and designated as E-99M in the FAB. The airplane has been updated to perform Airborne Early Warning and Control (AEW&C) functions, as well as participate in intelligence, surveillance, and airborne reconnaissance missions. 

Developed utilizing the platform established by the successful ERJ-145 regional jet, the FAB's E-99 is capable of detecting, tracking, and identifying targets in its coverage zone and transmit the information via Data Link. The aircraft conducts airspace surveillance, interception control and management, electronic intelligence, and border monitoring missions.

The E-99M project is led by the Combat Aircraft Program Coordinating Committee (COPAC) together with Embraer and international suppliers such as SAAB, Aeroelectronica International (AELI), and Rohde & Schwarz. Atech, a subsidiary of Embraer, is participating in the project by developing part of the command-and-control system, as well as six mission planning and analysis stations which will provide training and development opportunities for the crews. 

The EMB-145 AEW&C is also operated by the air forces of India, Mexico, and Greece.
