"Saab 2000 AEW&C comprises of Saab 2000 aircraft equipped with the advanced Erieye radar system and ground equipment."

The Erieye is an active phased array pulse Doppler radar operating in the 3.1GHz to 3.3GHz band and it is operational from three minutes after take-off and during climb and provides an effective surveillance area of 500,000km².

It is operational on a number of other aircraft including the Saab 340, Embraer R-99 and Embraer EMB-145.

The aircraft's main cabin is equipped with five mission operator consoles on the starboard side, as well as an active noise cancellation system, fuel tanks and mission equipment.

The mission operator consoles are responsible for system and sensor management; mission planning and simulation; track data processing; asset management and control; identification and allocation.

Powered by two Rolls-Royce AE 2100A turboprop engines, the aircraft's maximum cruise and patrol speed are 629km/h and 296km/h respectively.

Saab 2000 AEW&C features an electronic warfare suite that is based on the Saab Avitronics HES-21 electronic support measures (ESM) and self-protection suite.

The HES-21 also provides a ground-based support system (EGSS), which provides mission data for the aircraft electronic warfare system and for analysis of recorded data.

Additionally, the aircraft's electronic support measures (ESM) system comprises digital narrow band and wide band receivers and associated antennae.
