The Embraer R-99 is the Brazilian Air Force military designation of the ERJ 145 civil regional jet. The R-99 series are equipped with Rolls-Royce AE 3007 turbofan engines. The military versions provide 20% more thrust than the civil version.^{[citation needed]} The first flight was in 1999.

Variants[edit]

The R-99A/E-99/EMB 145 AEW&C is an Airborne early warning and control aircraft, equipped with the Erieye active electronically scanned array radar from Saab Microwave Systems (formerly Ericsson Microwave Systems) of Sweden. The FAB claims that it has 95% of the capability of the larger AWACS aircraft which are in service in the air forces of other nations. In 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.

The R-99B/R-99/EMB 145 MULTI INTEL is a remote sensing aircraft. It employs a synthetic aperture radar, combination electro-optical and FLIR systems as well as a multi-spectral scanner. The aircraft also possesses signal intelligence and C3I capabilities. In 2008 the FAB redesignated the R-99B as the R-99, for the Embraer EMB-145RS (Remote Sensing), a special military conversion of the passenger version of the Embraer ERJ-145LR.

The EMB 145 MP is the maritime patrol version of the R-99. It shares much of the same sensor suite as the R-99B, but most visibly, lacks the multi-spectral scanner and the side-looking radar. It retains many of the C3I and ELINT capabilities of the R-99B. Mexico was the launch customer for this variant.

The P-99/ would be the ASW modification of the EMB 145 MP and would have four underwing hardpoints, which could be mounted with a variety of torpedoes and/or anti-ship missiles. No prototype with those modifications have flown yet.

In Brazilian service, the E-99 and R-99 are based in Anapolis AFB. Five E-99s and three R-99s are operated by the Air Force as part of the SIVAM program.

Operational History[edit]

A Greek EMB-145-H was deployed to perform AEW missions as part of the enforcement of no-fly zone over Libyan Civil War (2011).^[2]
