Developed from Embraer ERJ-145
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. The airframe is based on the ERJ 145 civil regional jet and modified with specialised mission equipment based on the mission role desired. It is typically powered by a pair of Rolls-Royce AE1 3007 turbofan engines; the military versions provide 20% more thrust than the civil version. The maiden flight of the R-99 took place in 1999; it entered operational service with the FAB two years later.
The R-99A/E-99/EMB 145 AEW&C is an airborne early warning and control (AEW&C) aircraft, equipped with the Erieye active electronically scanned array radar from Saab Microwave Systems. During the aircraft's development, particular attention was paid to market interest as well the specific requirements of the Brazilian Air Force (FAB). The FAB have claimed that R-99 has 95% of the capability of larger AEW&C aircraft which are in service in the air forces of other nations. During 2008, the FAB redesignated the R-99A as the E-99, the factory name for the Embraer EMB-145SA (Surveillance Aircraft), a special military conversion of the passenger version of the Embraer ERJ-145LR.Ceiling

Despite the multiple variants, pilots need only one type rating to fly any variant of the ERJ aircraft. Companies like American Eagle utilizes this benefit with its mixed fleet of ERJ135ER/LR and ERJ145EP/LR/XR. Shared type-ratings allow operators to utilize a single pilot pool for any ERJ aircraft.
