Walk onto the flight deck of a Nimitz-class carrier and you’ll see rows of gray titanium. Most people gravitate toward the fighters. They want the sleek lines of the F-35 or the classic, aggressive stance of the F/18 Super Hornet. But tucked away, often with weird, pod-shaped protrusions hanging off their wings, are the EA-18G Growlers. They look almost identical to the standard Super Hornet. Honestly, though? They’re playing a completely different game.
The F/18 Super Hornet Growler doesn't care about dogfighting in the traditional sense. It isn't there to win a turning fight at 20,000 feet. It exists to turn the enemy's billion-dollar integrated air defense system into a collection of expensive, useless junk.
It's a weird bird.
Basically, the Growler is the specialized electronic warfare (EW) variant of the two-seat F/18 F Super Hornet. It replaced the venerable EA-6B Prowler, a plane that looked like a football with wings and required four people to operate. Moving that massive workload down to just two people—a pilot and a Weapon Systems Officer (WSO)—was a huge bet by Boeing and the Navy. It paid off. Today, the Growler is the only platform of its kind in production in the world. If a strike package is going into "contested" airspace, the Growlers go first. If they don't, nobody else comes home.
What makes a Growler different from a standard Super Hornet?
To the untrained eye, they’re twins. They share about 90% of the same airframe. They use the same F414-GE-400 engines. They fly at roughly the same speeds. But look closer at the wingtips. On a standard Super Hornet, you’d see rails for AIM-9X Sidewinder missiles. On the F/18 Super Hornet Growler, you see fixed ALQ-218 tactical jamming receiver pods. These are the "ears" of the aircraft.
They listen.
The Growler is a giant vacuum for electromagnetic energy. It picks up radar pings from hundreds of miles away, analyzes the frequency, and identifies exactly what kind of SAM (Surface-to-Air Missile) site is looking at it. Is it an old S-300? Is it the newer, much nastier S-400? The Growler knows.
Inside the nose, you won't find the M61A2 20mm cannon. It’s gone. In its place is a suite of electronic boxes. This is a plane that trades lead for logic. Instead of bullets, it uses the ALQ-99 high and low-band jamming pods. These things are essentially massive microwave ovens that focus all their energy on a specific radar frequency to "blind" the enemy. When those pods are screaming, an enemy radar screen looks like static on an old tube TV.

The transition from Prowler to Growler
The old EA-6B Prowler was a beast, but it was slow. It couldn't keep up with the Hornets it was supposed to protect. Imagine trying to guard a sprinter while you're wearing combat boots. It doesn't work. The Navy realized they needed an electronic attack platform that could fly the same profile as the strike fighters.
By building the Growler on the Super Hornet frame, they got a plane that could launch from a carrier, hit the tanker, scream into the target area at Mach 1.2, and then land back on the ship without needing a specialized logistics chain. It was a brilliant move for the taxpayer, too. Commonality kills costs. Mostly.
The "Growler" Myth: Can it actually kill other planes?
There’s a famous photo floating around military aviation forums. It shows a Growler with a silhouette of an F-22 Raptor painted on its side—a "kill" mark. People lost their minds when that photo first leaked. How could a jammer plane "shoot down" the world's premier stealth fighter in a training exercise?
It didn't use a gun.
During a Red Flag exercise at Nellis Air Force Base, a Growler pilot managed to get a "lock" on an F-22 using its electronic warfare suite and then "fired" an AIM-120 AMRAAM (yes, the Growler can still carry air-to-air missiles for self-defense). It was a fluke, sorta. But it proved a point. In the modern era, if you can mess with someone's sensors, you can kill them, even if they're "invisible" to traditional radar.
The F/18 Super Hornet Growler typically carries two AMRAAMs for "oh crap" moments. But its primary weapon is the AGM-88 HARM (High-speed Anti-Radiation Missile). This is a missile that literally sniffs out radar signals and flies down the throat of the transmitter. If an enemy turns on their radar to find the Growler, the HARM finds them. It’s a deadly game of chicken.
Why the Next Generation Jammer changes everything
The ALQ-99 pods currently used on the Growler are old. Like, Vietnam-era technology old. They use mechanical "turbines" (those little propellers on the front of the pods) to generate power. They’re finicky. They break. And honestly, they struggle with the modern "frequency hopping" radars used by peer adversaries.

Enter the NGJ (Next Generation Jammer).
The Navy is currently rolling out the ALQ-249. This isn't just an upgrade; it’s a total shift. It uses Active Electronically Scanned Array (AESA) technology to jam multiple targets at once on different frequencies. It’s digital. It’s fast.
- Mid-Band: Covers the most common threats.
- Low-Band: Aimed at "stealth-detecting" long-range radars.
- High-Band: Focuses on the radars that guide missiles in their final seconds.
The F/18 Super Hornet Growler with NGJ is basically a flying black hole for data. It can intercept communications, jam cell phone signals, and even (theoretically) inject malware into an enemy network wirelessly. We’re talking about "Cyber Warfare" at 30,000 feet.
The workload: Two seats, one massive headache
Flying a fighter is hard. Operating a Growler is a nightmare. The pilot has to fly the plane, stay in formation, and manage the kinetic weapons. The WSO in the back seat is the "Electronic Warfare Officer" or EWO.
The EWO has three large color displays. On these screens, they see a "god’s eye view" of the electromagnetic spectrum. They see lines representing every radar in a 200-mile radius. They have to decide, in seconds, which ones are a threat and which ones to ignore.
"You’re playing a 4D chess match while being shaken inside a paint mixer," one former EWO told me. You aren't just looking for planes; you're looking for energy. If you jam too much, you give away your own position. If you jam too little, your friends get shot down. It’s a delicate balance of "electronic silence" and "screaming into the void."
Limitations and the "Stealth" problem
The Growler isn't a stealth aircraft. It has a massive Radar Cross Section (RCS). If it’s flying with its jammers off, it’s a big, fat target on a radar screen. This is the central tension in US naval aviation. We have the F-35C, which is super stealthy but carries very few weapons. Then we have the Growler, which can hide the F-35 by jamming, but the Growler itself can be seen.

The goal is "协同" (Synergy). The Growler stays back a bit, throwing out a "shroud" of electronic noise. The F-35s slip through the gaps in that noise to deliver the kill blow. It’s a team sport. Without the Growler, the F-35's stealth is eventually beatable by advanced sensors. With the Growler, the F-35 becomes a ghost.
The Future: Is the Growler nearing the end?
The Navy recently stopped buying new Growlers. That sounds like bad news, but it’s actually because they have enough airframes to last into the 2040s. The focus now is on "Block II" upgrades.
This involves:
- Distributed Targeting Processor-Networked (DTP-N): A massive computer upgrade that lets the plane process data 10x faster.
- Tactical Targeting Network Technology (TTNT): A data link that allows Growlers to "talk" to each other and share jamming responsibilities automatically.
- Conformal Fuel Tanks: These sit on top of the fuselage to extend the range without adding drag or taking up weapon stations.
There’s also talk about "Loyal Wingman" drones. Imagine one manned F/18 Super Hornet Growler controlling three or four unmanned drones that carry the jamming pods. This keeps the humans further away from the danger zone while putting the jamming power right in the enemy's face.
Actionable insights: How to track the Growler's impact
If you’re a defense enthusiast or just someone interested in how modern wars are won, don't look at the dogfight stats. Look at the "SEAD" (Suppression of Enemy Air Defenses) missions.
- Watch the pod configurations: When you see photos of Growlers on deployment, look at the belly. If they’re carrying three pods, they’re expecting heavy radar interference. If they’re carrying two pods and extra fuel, they’re on a long-range "escort" mission.
- Follow the Australian connection: Australia is the only other country that flies the Growler. Their integration with US forces in the Pacific is the blueprint for how "interoperability" actually works. If the RAAF is buying more Growlers, it’s a signal that regional tensions are rising.
- Keep an eye on the NGJ testing: The ALQ-249 is currently in "Initial Operational Capability" (IOC) phases. Once that is fully deployed, the Growler becomes a completely different beast.
The Growler is the ultimate insurance policy. It’s the reason US pilots can fly into some of the most dangerous places on earth with a reasonable expectation of coming back. It’s not flashy, it doesn't have a starring role in Top Gun: Maverick, and it’s incredibly loud. But in a real fight? It’s the only plane that truly matters.
Most people don't realize how much the "invisible war" dictates the physical one. We like to think about missiles and bombs. But the F/18 Super Hornet Growler proves that if you control the bits and bytes, the missiles never even get a chance to launch. It’s the ultimate "off" switch for the enemy.
If you want to understand the next decade of conflict, stop looking at the wings. Look at the pods. That’s where the real power sits. It’s not about who has the fastest plane anymore; it’s about who has the smartest one. And right now, the Growler is the smartest kid in the class.
