Saab 2000 Erieye
Name	Saab 2000 Erieye
Role	Airborne early warning and control
Manufacturer	Saab AB
Status	In service

Saab 2000 Erieye is a surveillance and airborne early warning and control (AEW&C) system integrated on the Saab 2000 regional turboprop airliner platform. Developed by Saab AB in cooperation with Ericsson and other suppliers, the programme produced an aircraft optimized for airborne surveillance, border control, maritime patrol, and command-and-control missions. Operators have employed the type for NATO-aligned operations, counter-narcotics missions in South America, and regional airspace monitoring in Europe and Asia.

Development and Design

The Erieye programme originated during the 1990s when Saab AB sought to provide a lower-cost AEW&C solution compared with larger platforms like the Boeing 737 AEW&C and the E-3 Sentry. Drawing on experience from projects including the Saab 340 and collaborations with FMV (Swedish Defence Materiel Administration), Saab selected the Saab 2000 airframe for its speed and range. Design work involved integration efforts with suppliers such as SELEX Galileo, Harris Corporation, and Thales Group for systems engineering, as well as structural modifications overseen by aerodynamics teams formerly associated with MBB and British Aerospace projects. The configuration balanced airframe performance, payload capacity, and operational costs to meet requirements set by procurement agencies including the Royal Saudi Air Force and export customers.

Radar and Mission Systems

Central to the capability is the Erieye active electronically scanned array (AESA) radar developed by Saab AB in partnership with Ericsson and later iterations involving GKN Aerospace subcontractors. The radar provides 240-degree coverage via a long rectangle dorsal antenna, enabling functions comparable to systems installed on aircraft such as the Grumman E-2 Hawkeye and the Northrop Grumman E-2D Advanced Hawkeye. Mission systems integrate data links compatible with standards used by NATO, including integration with command nodes like those employed by SHAPE and regional air-defence networks in countries such as Pakistan and Greece. Onboard suites include identification friend or foe (IFF) transponders interoperable with assets from Lockheed Martin and Rafael Advanced Defense Systems, and signal-processing units adapted from projects involving BAE Systems and Raytheon.

Aircraft Modifications and Integration

Modifications to the Saab 2000 airframe included strengthening of the fuselage to support the dorsal radar fairing, installation of power generation upgrades influenced by work from GE Aviation and Honeywell Aerospace, and creation of mission consoles derived from human-machine interface research connected to Cranfield University and Kongsberg Defence & Aerospace. Avionics suites were certified in coordination with civil authorities like Luftfartsverket-era Swedish regulators and export certification bodies in Brazil, Thailand, and Poland. Structural changes also addressed electromagnetic compatibility consistent with standards used in Eurocontrol environments and testing facilities at institutions such as the National Aerospace Laboratory (NLR).

Operational History

Erieye-equipped Saab 2000s entered service with a range of air forces and government agencies. Early operators included the Royal Saudi Air Force and the Pakistan Air Force, which employed the platform for maritime surveillance and airspace monitoring during regional crises and peacetime patrols. Other deployments include missions supporting United Nations operations and multinational exercises alongside assets from France, Turkey, and United States Air Force detachments. Civil security roles have seen Erieye aircraft used in counter-smuggling operations with law-enforcement agencies in Colombia and as part of fisheries protection with agencies in Argentina and Chile.

Operators

Current and former operators comprise a mix of national air arms and government agencies: - Royal Saudi Air Force - Pakistan Air Force - Hellenic Air Force (Greece) - Argentine Air Force - Swedish Air Force (through Saab-owned demonstrators and trials) - Law-enforcement and coastguard units in Portugal and Thailand

Variants and Upgrades

Variants evolved from the baseline Erieye installation to include stretched mission endurance packages, maritime patrol-focused sensor suites, and export-customized electronics. Upgrades have incorporated AESA developments akin to those used in Saab GlobalEye projects, enhanced data-link compatibility with systems fielded by NATO members, and integration of electro-optical/infrared (EO/IR) pods supplied by companies such as FLIR Systems. Mid-life modernization programmes addressed cockpit avionics reminiscent of upgrades done on Bombardier Dash 8 and ATR 72 conversions, and sensor fusion work paralleled research in institutions like FOI (Research Institutes of Sweden).
