GlobalEye AEW&C: Saab’s Airborne Early Warning Platform Explained

GlobalEye is Saab’s most ambitious product: an airborne early-warning and control platform that packs the detection performance of a large dedicated AEW&C aircraft into a Bombardier business-jet airframe. The result is a system that can detect a low-flying threat at 458 km range from 35,000 ft altitude, track it through a complete airspace picture spanning more than 650 km, and do so for over 12 hours without a fuel stop — while simultaneously monitoring the sea surface for threats as small as a submarine periscope.

Why GlobalEye Is Different

Traditional AEW&C platforms — the Boeing E-3 Sentry, the E-7 Wedgetail — are built around large, purpose-designed airframes with rotating “rotodome” antennas. They are expensive to buy, expensive to operate and require long runways. GlobalEye takes the opposite approach. By mounting a fixed AESA radar in a dorsal ski-box on a Bombardier business jet, Saab achieves comparable or superior detection performance on a platform that can operate from any airport with a 6,500 ft runway, that costs significantly less per flight hour and that introduces a new capability: simultaneous tri-mission coverage of air, surface and subsurface domains from a single aircraft.

The Erieye ER radar’s two-faced fixed-array architecture sweeps 340 degrees of azimuth without mechanical rotation. AESA technology allows near-instantaneous beam steering, simultaneous tracking of multiple air and sea targets, and built-in ECCM resistance that rotating-antenna systems cannot match.

NATO AWACS Replacement Candidacy

NATO’s 17-aircraft E-3 Sentry AWACS fleet, which entered service in the 1990s, is approaching the end of its effective service life. In April 2026, Defence News reported that member states were actively considering GlobalEye — alongside the Boeing E-7 Wedgetail — as the successor platform. Sweden’s March 2024 NATO accession removes a political obstacle that previously complicated Saab’s access to alliance procurement decisions. France’s December 2025 order for two GlobalEye aircraft — a significant endorsement by a major NATO member — is widely seen as strengthening the platform’s candidacy.
