General Characteristics and Role
The Saab 340 AEW is a cost-effective Airborne Early Warning and Control (AEW&C) platform derived from the Saab 340 twin-turboprop regional airliner. It was developed to provide nations with a reliable, medium-range airborne radar and command system. Its most defining feature is the fixed, dorsal antenna known as the Ericsson ERIEYE radar. Unlike traditional rotating dome (rotodome) systems, the ERIEYE uses an active electronically scanned array (AESA) radar mounted on a long plank. This design provides high performance, electronic beam steering, and a superior detection range, while its smaller size compared to jet-based AEW&C systems offers excellent economy and operational flexibility.

Radar System and Performance
- Radar System: Ericsson ERIEYE Active Electronically Scanned Array (AESA) radar.
- Antenna Type: Fixed, dorsal “plank” antenna.
- Coverage: Provides a 120-degree sector coverage on either side of the aircraft (240 degrees total) but can be rapidly switched to focus radar energy across a smaller, high-priority sector.
- Endurance: Over 5 hours (standard mission profile).
- Propulsion: 2 x General Electric CT7-9B turboprop engines.
- Cruise Speed: Approx. 467 km/h (290 mph; 252 knots).
Service and Export
- Operators: The Saab 340 AEW has been exported to several countries, including Sweden (as the S 100B Argus), Thailand, and the UAE.
- Cost-Effectiveness: The use of the reliable, off-the-shelf 340 airliner chassis and the fixed ERIEYE array makes it significantly less expensive to acquire and operate than larger jet-based AEW platforms.
- Successor: The ERIEYE system proved so successful that it was integrated into larger and faster jet platforms (like the Saab 2000 and the Bombardier Global 6000) for the next generation of Airborne Early Warning systems.
