Embraer R-99

The Embraer R-99 and P-99 are military versions 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. The first flight was in 1999.

Variants
The R-99A/E-99/EMB 145 AEW&C is an Airborne Early Warning & Control aircraft, equipped with the Erieye airborne 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 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.

The P-99/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. The P-99 also carries four underwing hardpoints, which can be mounted with a variety of torpedoes and/or anti-ship missiles. Mexico was the launch customer for this variant.

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
A Greek R-99 was deployed to perform AEW missions in the framework of the enforcement of no-fly zone over Libyan civil war (2011).
