The GlobalEye AEW&C is Saab's airborne early warning and control aircraft, and the short version is this: it takes a long-range Bombardier business jet, bolts a powerful radar to the top, and turns it into a flying command center that can track aircraft, ships, and ground vehicles all at once. It first flew in 2018 and entered service in 2020. Since then it has gone from a single export customer to a platform that the UAE, Sweden, France, and now Canada all want. If you have only ever heard of the big dome-on-top AWACS planes, this is the newer, leaner idea of what airborne surveillance looks like.
What I find most interesting about the GlobalEye is that it keeps winning on a quality that does not photograph well: it does several jobs at once that older aircraft needed separate platforms for. That is the thread running through this whole post. Below is what each section covers.
What the GlobalEye AEW&C Actually Is
AEW&C stands for Airborne Early Warning and Control. The job is simple to describe and hard to do. You put a radar high in the sky so it can see much farther than any radar stuck on the ground, then you use that picture to direct fighters, warn ships, and build a real-time map of everything moving in a region. Ground radars get blocked by the curve of the earth and by terrain. An aircraft at 35,000 feet does not.
The GlobalEye is Saab's modern take on that idea. Instead of a wide-body airliner, it starts with the Bombardier Global 6000/6500, a long-range business jet that Canadians build in Toronto. Saab strips it out, reinforces the airframe, and mounts a long antenna housing on the spine that the company nicknames the "ski-box." Inside that housing sits the radar that does most of the work. The Swedish Air Force gives the aircraft its own designation, the S 106, which you will see in European coverage.
The Radar Is the Whole Point
Everything about the GlobalEye AEW&C exists to carry one piece of equipment as high and as long as possible: the Erieye Extended Range radar. It is an S-band active electronically scanned array, which is a technical way of saying it steers its beam electronically instead of physically spinning a dish. That lets it stare hard at one area while still scanning everywhere else, and it makes the radar much harder to jam.
That number is the one worth sitting with. Saab says the radar's instrumented range significantly exceeds 650 km, compared with about 450 km on the previous Erieye version, and the company gives the example of a GlobalEye at 35,000 feet detecting a target down at 200 feet from 458 km away. A ground radar trying to do the same job sees roughly a tenth of that distance against low flyers, because the horizon gets in the way. Lifting the radar is the entire game, and the Erieye ER is built to work in heavy clutter and jamming, which is exactly the environment a modern conflict creates.
Lifting the radar above the curve of the earth is the entire point of an early warning aircraft, and the GlobalEye does it with a sensor that sees well past 650 kilometers.
It Watches the Sky, the Sea, and the Ground at Once
This is where the GlobalEye separates itself from most of its rivals. Saab built it as a multi-domain aircraft, meaning a single platform can run air, sea, and land surveillance at the same time rather than specializing in one. The Erieye ER handles the air picture, but it shares the aircraft with a separate maritime radar, an electro-optical camera turret, and ground-tracking modes. One crew, one orbit, three jobs.
| Domain | Sensor | What it tracks |
|---|---|---|
| Air | Erieye ER AESA radar | Fighters, cruise missiles, drones, low-observable targets |
| Sea | Leonardo Seaspray 7500E radar | Ships down to small vessels and even periscopes |
| Land | Ground Moving Target Indication mode | Vehicles and moving objects on the surface |
| Identification | Star SAFIRE EO/IR turret, AIS, ISAR | Visual confirmation and target classification |
The maritime piece is more impressive than it sounds. The combination of the Erieye ER and the maritime surveillance radar lets the aircraft pick out objects as small as a periscope, and it carries an automatic identification system, an electro-optical system, and inverse synthetic aperture radar for sorting out what each contact actually is. If you are a coastal nation worried about submarines, smuggling, or contested waters, that single capability can justify the whole purchase.
Why a Business Jet Beats a Converted Airliner
The instinct, when you picture a radar plane, is to imagine something huge. A 707, a 737, a wide-body with a giant rotating dome. So why did Saab go small? The answer comes down to three things that matter more in practice than ramp presence: endurance, runway access, and cost per flight hour.
The Global 6000/6500 is purpose-built to fly far and stay up long. Saab quotes endurance of more than 11 hours, and the company's own materials push that figure past 12 hours. That means fewer aircraft to keep one orbit covered around the clock. The jet also needs a much shorter runway than an airliner, so it can operate from smaller and more dispersed airfields, which matters a lot if you are trying to survive a first strike. And a business jet simply costs less to fly per hour than a four-engine airliner, which adds up fast over a 30-year service life.
If you are researching this for a procurement decision or a school project and want the competing platforms broken down the same way, that comparison is worth having open in another tab as you read on.
Who Actually Flies It
A platform is only as credible as its order book, and the GlobalEye's has grown steadily. The launch customer was the United Arab Emirates, which is the only operator flying the aircraft today. Sweden was next, ordering aircraft to replace its older Saab 340 early warning turboprops after donating two of them to Ukraine. France signed on after that, and Canada is the newest name on the list.
| Country | Aircraft | Status |
|---|---|---|
| United Arab Emirates | 5 | In service, full fleet delivered |
| Sweden | 3 | On order, deliveries from around 2027 |
| France | 2 | On order |
| Canada | Up to 6 | Preferred supplier, negotiations underway |
The Canada line is the one to watch. Canada selected the GlobalEye as its preferred airborne early warning solution and is set to become the fourth operator after the UAE, Sweden, and France. Prime Minister Mark Carney announced the choice at the CANSEC exhibition in Ottawa on 27 May 2026, with the requirement covering six aircraft under a program valued at more than five billion Canadian dollars, aimed at Arctic radar coverage, sovereign command and control, and maritime surveillance. No contract is signed yet, but preferred-supplier status is a serious step.
GlobalEye vs the Boeing E-7 Wedgetail
This is the comparison most people actually came to read, so let's be direct about it. The E-7 Wedgetail is Boeing's airborne early warning aircraft, built on a 737 airliner with a fixed radar antenna on top. It is a capable, combat-proven aircraft that the UK, Australia, and others fly. For years it was the default Western choice. The GlobalEye is the smaller, newer, multi-domain challenger. They are aimed at the same job from opposite directions.
| Feature | GlobalEye | E-7 Wedgetail |
|---|---|---|
| Base aircraft | Bombardier business jet | Boeing 737 airliner |
| Core mission | Air, sea, and land in one | Primarily air early warning |
| Endurance | More than 11 hours | Shorter, larger crew |
| Runway needs | Short, dispersible | Standard airliner runway |
| Program maturity | In service since 2020 | Mature, but recent deliveries delayed |
The honest read is that neither aircraft is simply "better." The Wedgetail brings a larger cabin, more onboard operators, and a long combat record. The GlobalEye brings lower running costs, longer time on station, and that multi-domain sensor mix from one airframe. It is also worth noting that the first Wedgetail for the UK arrived in May 2026 after a roughly three-year delay tied to parts obsolescence and Boeing fitting-out issues. Schedule risk like that pushes some buyers toward the platform that is already flying.
Neither aircraft is simply better. One is the proven heavyweight, the other is the efficient multitasker, and buyers are increasingly deciding the second math wins.
A common mistake I notice in casual coverage is treating the GlobalEye win in Canada as purely political. Trade tensions with the United States certainly mattered. But it also helps that the aircraft is built on a Canadian-made airframe and that Saab offered to build a chunk of the fleet inside Canada. Politics opened the door; the platform's actual fit walked through it.
What the Canada Deal Tells You About Where This Is Going
Step back from any single contract and a pattern shows up. Pairing Swedish manufacturer Saab with Canadian airframe-maker Bombardier has been described as a shift in a market that was historically an American preserve. For decades, "radar plane" effectively meant "American radar plane." That assumption is loosening, and the GlobalEye is the clearest sign of it.
There are two reasons this matters beyond defense trivia. First, buyers increasingly value sovereignty: the ability to maintain, upgrade, and even build the aircraft themselves rather than depending entirely on one foreign supplier. Saab's pitch to Canada leaned hard on exactly that. Second, the unmanned future is already being tested. Saab has flown an early warning radar on an unmanned aircraft, which hints at where this whole category drifts over the next decade. The crewed GlobalEye is the present, not the endpoint.
The Bottom Line
The GlobalEye AEW&C is what happens when someone rethinks the radar plane from scratch: a long-endurance business jet carrying a radar that sees past 650 kilometers, watching air, sea, and land at the same time, from runways that bigger aircraft cannot use. It is not the biggest option on the market, and it does not need to be. The order book from the UAE, Sweden, France, and now Canada is the argument that matters.
If you want to keep building a real mental model of modern air power, the most useful next step is to read these aircraft side by side rather than one at a time. Pull up the GlobalEye, the E-7 Wedgetail, and the legacy E-3 Sentry together, compare them on endurance and cost the way this post laid out, and the choices air forces are making will start to make a lot more sense. That comparison is the natural follow-on to this guide, and it is where the interesting trade-offs really live.
