Sweden Gives Ukraine Saab 340 Early Warning Spy Planes

By Olawale Abaire, Warrior Editorial Fellow

In a recent announcement, the Swedish government will be equippping Ukraine with two Saab 340 airborne early warning and control (AEW&C) aircraft. The Saab 340 AEW&C, equipped with the advanced Erieye radar system, represents a significant tactical advancement for Ukraine’s air and naval defenses. This deployment is not just a material contribution but a strategic augmentation of Ukraine’s military apparatus, potentially altering regional security dynamics.

The Saab 340 AEW&C aircraft, known within the Swedish forces as ASC 890 or S 100D Argus, carries a sophisticated suite of surveillance technologies centered around the Erieye radar system. This active electronically scanned array (AESA) radar is notable for its capability to track multiple air and sea targets over a distance of approximately 280 miles and at an operational altitude of 20,000 feet. Such capabilities allow for expansive battlefield surveillance, providing Ukraine with an unparalleled ‘lookdown’ capability which is critical for monitoring low-flying or stealthy drones and cruise missiles that Russian forces frequently deploy.

Integrating these aircraft into Ukraine’s military infrastructure is expected to significantly enhance the operational dynamics of the forthcoming F-16 fighters by providing advanced target acquisition and prioritization. This could dramatically increase Ukraine’s air defense’s efficacy and response capabilities, essentially transforming their approach to airspace control and management.

Comparatively, the Erieye-equipped Saab 340 AEW&C offers a broader range of detection and engagement possibilities than ground-based radar systems, often hindered by terrain and line-of-sight constraints. The airborne platform provides a dynamic and flexible surveillance solution capable of real-time data transmission to ground and air units via the NATO-standard Link 16 datalink, thus integrating seamlessly into a modern integrated air defense system (IADS).

However, the deployment of these aircraft also introduces new vulnerabilities. With only two units provided, continuous coverage is unfeasible, and the aircraft must be judiciously employed to maximize their strategic value while minimizing exposure to risks. Likely operating from the western regions of Ukraine to evade direct confrontations, these aircraft’s strategic deployment and survival will be crucial, given their potential as high-value targets for Russian forces.
