In a major and unexpected move, Sweden has announced it will supply Ukraine with two Saab 340 airborne early warning and control (AEW&C) aircraft as part of a new SEK 13.3 billion ($1.25 billion) military aid package. This aid marks Sweden's largest support package to date, aiming to bolster collective air defense capabilities. The announcement came on May 29, when the Swedish government detailed its "Military Support Package 16," with the Saab 340 AEW&C aircraft, also known as the S 100D Argus or ASC 890, being the central component.
The Swedish Ministry of Defense stated that these aircraft would provide Ukraine with a new capability for airborne radar reconnaissance and combat control against air and sea targets, significantly enhancing Kyiv's long-range detection and targeting abilities. Equipped with advanced Erieye radars based on Active Electronically Scanned Array (AESA) technology, these aircraft will revolutionize Ukraine’s surveillance capabilities.
Currently, the Swedish Air Force operates only two of these sophisticated surveillance planes. The aid package indicates that one or both of these planes will be transferred to Kyiv, temporarily reducing Sweden’s AEW&C capability. To address this, Stockholm will expedite the acquisition of an additional Saab GlobalEye platform and accelerate the delivery of two units already on order, with the first new aircraft expected by 2027.
Sweden’s Minister of Defense, Pal Jonson, noted that sending the planes followed intensive discussions with coalition countries and emphasized that the ASC 890 aircraft would significantly bolster Ukrainian air defense. These advanced aircraft will complement the F-16 fighter jets to be supplied by Belgium, Denmark, Norway, and the Netherlands, forming a robust air force coalition for Ukraine. The timeline for the delivery of the ASC 890 aircraft has not been specified.
AEW&C Aircraft for Ukraine
The deployment of these AEW&C aircraft holds significant strategic value. They offer extensive overhead surveillance, crucial for detecting low-flying threats like Russian drones and cruise missiles that often evade conventional radar systems. The Saab 340 AEW&C will play a vital role in coordinating F-16 fighter operations by detecting, prioritizing, and guiding targets for interception, thus enhancing Ukraine's defense posture.
Valerii Romanenko, a leading researcher at the National Aviation University of Ukraine, emphasized the transformative impact of these aircraft, highlighting their ability to unlock the full potential of the multi-role F-16 fighters. The Saab 340’s integration with the NATO-standard Link 16 datalink communications system ensures seamless coordination with allied air defense systems, providing a comprehensive air defense picture and targeting data to compatible systems both airborne and on the ground.
Russian Threats and AEW&C Vulnerability
Despite their operational advantages, AEW&C systems are vulnerable to hostile actions. Earlier this year, the Russian Air Force lost two Beriev A-50 AWACS planes to Ukrainian missile attacks, underscoring the strategic importance and susceptibility of these aircraft. The Saab 340 AEW&C, with a detection range of up to 450 km, would need to operate within Ukrainian airspace to be effective, making them targets for Russian MiG-31BM and Su-57 fighters armed with R-37 air-to-air missiles, which have a range of 300 kilometers.
While the MiG-31BM presents a detectable threat, the Su-57’s advanced stealth capabilities pose a significant detection challenge. Additionally, the R-37M missiles are exceedingly difficult to evade. The Mikoyan MiG-31BM interceptors near the Russia-Ukraine border extend the threat radius across Ukrainian airspace, often forcing Ukrainian fighter pilots to abort missions. The relatively slower and less agile Saab 340 is more vulnerable compared to the four-engine A-50, which can reach higher speeds and altitudes.
Conclusion
The introduction of Saab 340 AEW&C aircraft to Ukraine’s military will significantly enhance its surveillance and defense capabilities. However, these gains come with increased vulnerability to advanced Russian fighter jets and missile systems. The balance of power in the region will be closely monitored as these developments unfold.
