So you think you know the answer on who wins between the F-16V and the J-39E? Well let’s see if you agree with our resident expert, former F-16 pilot, and current SkunkWorks test pilot Nate “Buster” Jaros.
The rapidly approaching target is locked in the F-16V FCR (Fire Control Radar). Through his HUD (Heads-Up Display) and the JHMCS (Joint Helmet Mounted Cueing System) helmet the pilot can see a diamond hovering in space, right where the locked target should be. However, it’s too soon to visually make out an aircraft. He squints, there is nothing to see but clouds and blue sky.
The FCR screen says something entirely different and much more ominous is out there. He is locked to a fast moving target, and it’s pointing straight at him. Hot aspect. The closure rate is fantastic, well over 1,000 knots.
His experience tells him that this is no cargo plane, it’s no apparition either. It’s got to be a fighter, and the other pilot is coming straight at him, certainly trying to kill him.
His RWR (Radar Warning Receiver) bleeps in his ear, and a symbol appears on the screen at the 12 o’clock position. The approaching bandit has locked up his Viper.
He cross checks the diamond in his field of view. It’s still off the nose and level. The radar system says they are ten miles away now, and the closure rates have increased to 1,100 knots.
This other pilot means business.
He’s approaching aggressively and it will no doubt be a head on pass. There is no longer time to out-maneuver this unknown fighter, as turning now would simply set up a nice sweet shot for the approaching bandit, and put our F-16 into some kind of WEZ (Weapons Engagement Zone).
Like knights in a joust, he’s got to stay nose on to the bandit, stay aggressive and be ready to launch weapons, and fight. It’s too late to turn and run away.

Five miles! Still no “tally” but he can see the diamond drifting slightly low and off the left side of the nose. It’s going to be a head-on pass, down the left side. This is it! Eyes outside, get the tally!
A black dot, no bigger than a fleck of dirt on the canopy is the first thing he notices. It’s an easy tally at three miles as the enemy craft crosses in front of a white cloud. It reminds him of an ant crawling on a bed sheet. Within two seconds he can now see the definitive shape of a triangle, with a nose and a canopy. Maybe canards?
The aircraft will pass each other in another two seconds.
The fighters both roll towards each other, set lift vectors on each other and prepare for the canopy-to-canopy pass. The gray shape inside the diamond blooms instantly, as if it exploded. Not into parts and pieces, but instead into a live airplane, with color, markings, insignia, a clearly visible canopy, and missiles, all easily seen in the split second heartbeat of this pass—then it’s gone.
“ID HOSTILE GRIPEN!” he shouts on the radio. He adjusts his lift vector to the adversary’s plane of motion, and pulls back on the stick. Here come the Gs.
“Fight’s On!”
The F-16V versus the J-39E. Both are considered “top of the line” fourth generation fighter aircraft. Both have exceptional radars, cueing systems, engines, and technology. Who would win this fictional dogfight between the new mighty Viper “V” and the superb J-39E Gripen? Let’s dig a little deeper.
First the similarities. And I’m not going to split hairs here. I could care less if one aircraft carries a few more bullets, or can go 200 nm farther, or 5,000 feet higher.
I care about the stuff that the fighter pilot cares about…the “meat” of the aircraft, and what it can really do, on a real day with real weapons and fuel on board. Not some artificial test results published on the internet under certain and exact circumstances.
How do the systems and capabilities of the machine help the pilot?
Both fighters can do Mach 2, fly about 50,000 feet MSL (Mean Sea Level), and both are fantastic multi-role, single-seat fighters. Each has long range and heat-seeking missiles, as well as an array of dumb and smart bombs, and air-to-surface missiles at their disposal. Both have fly-by-wire controls and can in-flight refuel. They each have an AESA (Active Electronically Scanned Array) radar, and fuel loads are similar.
Both have solid HUDs and HMCS (Helmet Mounted Cueing Systems) and can carry external targeting and laser pods. Both also can haul Link-16 datalink, ROVER (for secure video communication with ground parties), and satellite communication capabilities, and both are also touted as being able to super cruise, with limited air-to-air weapons on board. Impressive no doubt.
Now the differences.
The F-16V
The F-16V is the same ole F-16 your pappy flew, but with a few more modern enhancements that makes this Viper much more deadly. While the “V” retains all the incredible capabilities of the normal F-16, this new variant carries some new goodies that the J-39E doesn’t have.
The V model gets some new displays in the cockpit. There is limited data and photos of these new displays, however it is supposed to have a color MFD (Multi-Function Display) in the center position, in addition to other new advanced displays on the sides. Gucci!
It is surmised that this new cockpit display also contains some amount of sensor fusion. A cockpit that is said to be “sensor fused” allows for multiple incoming data pathways to present themselves on one display. In a sense, overlaying all the battlefield knowledge onto one presentation.
This aids the pilot’s workload and SA and eliminates the need for him or her to use a lot of “brain bytes” to interpret and react to the situation around him as he gets data from different systems on board the jet. It’s like flipping burgers on five grills at the same time, versus having one grill with everything on it.
The last two key distinctions for the new Viper are a little less “meat and potatoes” however, they are extremely important. The F-16V has actually flown, and is being tested right now. This is paramount, and also means that the concept and design has been funded and should be entering low rate production. The F-16V could be on the battlefield soon.
Secondly, the F-16V is building upon an already existing and proven combat design. Sure, the J-39 is an already existing design too, but further investigation reveals that the E model will have a whole new powerplant, avionics, fuel tanks and capacities, and cockpit.
It’s the shell of a J-39, but it’s entirely new. It’s about as similar to the old J-39 as a modern laptop is to a toaster. The new E model will require multiple test programs and flight hours to see IOC, so it’s an entirely different animal. Additionally, the baseline J-39 has seen limited actual combat operations, while F-16s fly thousands of combat hours a month over various global hotspots.
While less tangible, these key differences give the F-16V a huge edge in the global combat arena.
The J-39E
The J-39E is a fairy tale unicorn…but a bad ass fairy tale unicorn at that! It has a reported cockpit suite that embraces sensor fusion, the future of cockpit displays. It has a lower RCS (Radar Cross Section) than a traditional Gripen, and supposedly it will also have an IRSTS (Infra Red Search and Track) system that can detect and track targets passively, using their heat signature alone. Some capability against certain low RCS stealthy targets are being touted with the IRSTS, but that capability is yet to be tested and documented on the new Gripen.
The J-39 also has a smaller engine than the F-16V, but this canard-carrying bird is also lighter. The Viper’s GE powerplant produces almost 30,000 pounds of thrust for the Viper’s max takeoff weight of 48,000 pounds. Compare that to the new engine (same as the F/A-18) on the J-39E with it’s 22,000 pounds of thrust for the much lighter 31,000 pound max takeoff weight Gripen.
That’s a 0.625 ratio for the F-16 and a 0.70 ratio for the Gripen E if you’re bad at the math. At max weight, the J-39E has a better thrust-to-weight ratio, and a fuel burn rate at combat power settings will be slightly lower than the F-16 as well.
Lastly, some sources say that the J-39, with its large forward canards can sustain flight at much higher AoA (Angle of Attack) than the F-16. Over 50 degrees AoA, as compared to the 35 degree limits of the F-16.
Both fighters are limited by fly-by-wire flight control logic and “HAL” as we call it, but the canards and thrust-to-weight ratio of the J-39E should give it a slight advantage in the slow-speed “phone booth” regime.
But recall that the E model Gripen is still in development. That’s a big “what if” for Saab and any country looking to purchase a few new E models. Brazil ordered some J-39Es back in October of 2014, but as of August 2016, none have been delivered. Saab is still in “development.”
Only time will tell whether or not this bad ass unicorn will pass all the tests and enter full rate production.
The Verdict
The F-16V is the clear winner here, because it exists and flies today. It is the most combat proven design in the history of fourth generation multi-role fighter airpower, and it is actual flying and being tested now. I vote for IT as the obvious winner of the F-16V versus J-39E mock-fight.
However, (as a former F-16 operator, this part pains me to say) that if the J-39E becomes a reality, and all the discussed items become real too, IT will be the clear winner. The lower RCS design, the IRSTS, and the higher thrust-to-weight ratio give the J-39E the edge for the top spot on the fourth generation multi-role fighter podium. It will be one highly capable and extremely difficult unicorn to defeat by any capable adversary!
