Honestly, if you ask most aviation geeks about the "best" fighter jet, they’ll start shouting about the F-35’s stealth or the F-22’s raw power. But there’s this sleek, single-engine bird from Sweden that usually gets shoved into the "budget option" category. That’s a mistake. The JAS 39 Gripen isn't just a cheap alternative for countries that can't afford American hardware. It's a masterclass in pragmatic engineering that solves problems most 5th-generation jets aren't even designed to handle.
Take the landing strip, for instance. Most modern fighters need miles of pristine, sweeping concrete and a small army of technicians just to get off the ground. The Gripen? It was built with the "Bas 90" philosophy. Basically, the Swedes assumed their main airbases would be nuked or cratered within the first hour of a war. So, they made a jet that can land on a regular two-lane highway, refuel, rearm, and take off again in under ten minutes. All it needs is a 800-meter stretch of road and a handful of conscripts with a fuel truck.
What Most People Get Wrong About the JAS 39 Gripen
The biggest myth is that the Gripen is just one plane. It’s actually two very different beasts. You’ve got the older Gripen C/D models—the workhorses you see flying for the Czech Republic, Hungary, and South Africa. Then you have the new Gripen E.
Don’t let the similar looks fool you. The "Echo" is practically a new aircraft. It’s got a beefier GE F414G engine, which gives it about 25% more thrust. More importantly, the internal fuel capacity jumped by 40%. That was always the knock on the older Gripens—they didn't have the "legs" for long-range missions. The E-series fixed that. It also moved the landing gear out to the wings to make room for two extra hardpoints. Now it carries ten weapons stations instead of eight.

The "App Store" Logic of the Gripen E
The real genius of the Gripen E isn't the airframe; it’s the brain. Saab did something radical with the avionics. They separated the flight-critical software (the stuff that keeps the plane from crashing) from the mission software (the radar, weapons, and electronic warfare).
In a traditional jet, if you want to add a new missile, you have to recertify the whole flight system, which takes years and costs billions. On a Gripen, it’s closer to updating an app on your phone. You can swap out tactical code without touching the flight controls. This is why the Gripen was the first jet in the world to integrate the Meteor missile—the terrifying long-range "ramjet" air-to-air weapon that makes even F-35 pilots nervous.
Electronic Warfare: Hiding in Plain Sight
People love to talk about stealth. But the JAS 39 Gripen takes a different path. Instead of trying to be physically invisible to radar through expensive coatings and weird shapes, it uses "electronic stealth."
The new Gripen E features a Gallium Nitride (GaN) based Electronic Warfare suite called Arexis. Without getting too deep into the physics, GaN allows for much higher power and wider bandwidth than older tech. It doesn't just jam radar; it creates a digital "fog" or "ghosts" that make it incredibly hard for an enemy to get a lock.
During exercises like Red Flag or Loyal Arrow, Gripens have famously "shot down" F-15s and Eurofighters. Why? Because they’re small, they’re electronically "loud" only when they want to be, and they share data like crazy. If one Gripen sees you, every Gripen in the neighborhood knows exactly where you are without even turning their own radars on.
NATO's Newest Sharpest Tool
With Sweden finally in NATO, the Gripen’s role has shifted overnight. As of early 2026, Swedish Gripens are already pulling shifts for NATO's Enhanced Air Policing. Just this January, Sweden announced it would deploy up to eight jets to Poland to patrol the Baltic region.
It’s a huge deal. For decades, the Swedish Air Force was "neutral," focusing only on defending its own borders. Now, these jets are fully integrated into the Allied command chain. They’re even looking at adding Taurus cruise missiles by 2028, turning the light fighter into a serious long-range strike platform.

The Cold Reality of the Price Tag
Let’s talk money. This is where the Gripen usually wins the argument.
- Operating Cost: While an F-35 might cost $30,000 to $33,000 per hour to fly, the Gripen C/D sits around $4,000 to $8,000.
- Availability: Because it’s so easy to maintain, you can keep more Gripens in the air more often.
- The Ukraine Factor: In late 2025, Saab and the Swedish government signaled they're ready to produce up to 150 Gripen E fighters for Ukraine if a deal is finalized. For a country with limited runways and a need for high-frequency missions, the Gripen is the perfect fit.
The JAS 39 Gripen isn't trying to be the F-35. It doesn't want to be a stealthy quarterback sitting miles behind the lines. It’s a scrappy, high-tech knife-fighter designed to survive in a mess, land on a road, and get back into the fight before the enemy even realizes what happened.
Actionable Insights for Aviation Observers
If you're following the evolution of modern air power, keep your eyes on these three things regarding the Gripen program:
- Watch the Colombia and Thailand orders: Colombia just signed for 17 Gripen E/Fs, and Thailand is expanding its fleet. These exports are the lifeblood that keeps Saab’s production lines moving and proves the jet’s viability outside of Northern Europe.
- Monitor the NATO Integration: See how the Swedish Air Force handles its first foreign deployments in Poland and Latvia. The ability of the Gripen to talk to F-35s and Rafales through Link-16 and other datalinks will be the real test of its "modern" credentials.
- Look at the "Loyal Wingman" Tech: Sweden is already hinting at using Gripen software to control unmanned drones. Given their decoupled avionics architecture, they might actually beat the Americans to a fully operational, integrated drone-fighter team.
