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. The airframe is based on the [[Embraer ERJ 145 family|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 plc|Rolls-Royce]] [[Rolls-Royce AE 3007|AE1 3007]] turbofan engines; the military versions provide 20% more thrust than the civil version.<ref>{{Cite web |url = https://aircrafttotaal.nl/embraer-aew-145.html |title = Embraer AEW 145 |access-date = 1 February 2020 |archive-date = 1 February 2020 |archive-url = https://web.archive.org/web/20200201183004/https://aircrafttotaal.nl/embraer-aew-145.html |url-status = dead }}</ref> The [[maiden flight]] of the R-99 took place in 1999; it entered operational service with the FAB two years later. 

Export customers for the type include the [[Hellenic Air Force]], [[Mexican Air Force]], and the [[Indian Air Force]]. Some customers have opted to buy the airframe and separately outfit it with their own electronics packages. It has been deployed in response to various events, including the [[Shining Path]] hostage crisis, the loss of [[Air France Flight 447]], the [[2011 military intervention in Libya]], and the [[Amazon Surveillance System|SIVAM]] program. During the 2010s, the FAB opted to modernise their R-99 fleet, not only extending its service life but also giving it new capabilities, such as a longer effective radar range and [[datalink]] facilities. Embraer has proposed new variants of the type, such as the armed ''P-99'' [[anti-submarine warfare]] (ASW), which is to be capable of using both [[torpedo]]es and [[anti-ship missile]]s.
