Embraer R-99
The Embraer R-99 is the Brazilian Air Force (FAB) military designation of the EMB-145-RS. Various models of the aircraft have been produced to perform special mission duties, including the E99 for airborne early warning and control (AEW&C) missions, the R-99 for remote sensing, and the P-99 for maritime patrol. Development of the R-99 began during the 1990s in response to a FAB requirement for an airborne early warning and control (AEW&C) platform, as well for the export market.
