Saab 340 AEW&C

Also known as
  • Saab-340AEW
  • Saab 340 AEW
  • Saab 340 Erieye
  • ASC 890
  • S 100D Argus
  • S 100B Argus

The Saab 340 AEW&C is a Swedish Saab 340 turboprop adapted into an airborne early warning and command platform around the PS-890/Erieye radar. Saab traces the Swedish Argus line from FSR 890 surveillance aircraft to the ASC 890/S 100D command-and-control upgrade, and Sweden selected the type as a high-value air-surveillance donation to Ukraine in 2024 with training, technical support, and air-defense integration support.

Role in Conflicts

2014 Russia-Ukraine War
Reconnaissance & SurveillanceCommand, Control & CommunicationsAir Defense

Sweden announced ASC 890 airborne surveillance and control aircraft for Ukraine in support package 16, with training, technical equipment, and command-and-control support for long-range air and maritime target detection. A Sweden-Ukraine security agreement tied the transfer to Ukrainian air-defense effect, Ukraine's defence ministry later thanked Sweden for delivering ASC 890 aircraft, and later open-source reporting described apparent Saab 340 AEW&C flight activity over Ukraine while noting verification limits.

Role details
Airborne Surveillance Role

The Ukraine transfer is best read as an enabling aircraft rather than a strike platform. Swedish government sources describe the ASC 890 as an airborne surveillance and command-and-control capability for air defense, while Saab describes Erieye-family aircraft as systems for early warning, air and sea surveillance, and networked situational awareness.

Radar layout

Erieye active electronically scanned array radar in the distinctive balance-beam fairing above the fuselage.

Ukraine context

Swedish donation package for Ukraine, with training, technical equipment, and command-and-control support attached to the aircraft transfer.

Evidence limit

Public sources support transfer, delivery, intended air-defense role, and apparent in-country flight activity; detailed Ukrainian tasking and mission results remain undisclosed.

Development And Upgrade Path

Saab's own history frames the Saab 340 AEW&C as part of Sweden's move from a national airborne-surveillance radar program to a command-and-control aircraft. The PS-890/FSR 890 radar line began as a Swedish Armed Forces development order in the mid-1980s, was integrated on Saab 340 airframes for the Argus force, and later evolved into ASC 890 when the system was upgraded into an on-board command center.

FSR 890

Swedish airborne surveillance radar system delivered on Saab 340 Argus aircraft for the Swedish Air Force.

ASC 890

Upgrade path that Saab described as a NATO-compatible C2 platform able to support Gripen and other airborne platforms.

Export context

Saab later described Saab 340 AEW sales to Poland as Saab 340 aircraft equipped with Erieye radar, ground equipment, logistics, and support services.

Variants

Saab 340 AEW&C naming separates the base Saab 340 airframe, Swedish S 100 Argus service designations, and ASC 890 mission-system upgrades.
