F-16 vs F-35: Which Fighter Is Better, and Why the Air Force Is Replacing One With the Other

How we compare the F-16 and the F-35

These jets are a generation apart. The F-16 is a 1970s lightweight fighter that US squadrons still fly in upgraded F-16C and F-16D form, and the F-35A is the stealthy fifth-generation jet the Air Force is buying to replace it.

We compare them on four measures: who sees and shoots first, performance and range, cost and readiness, and combat record. What separates the two generations is the subject of our guide to the five generations of fighter planes.

Full specifications for the Lockheed Martin F-35 Lightning II and the Lockheed Martin F-16 Fighting Falcon sit in our aircraft database. Both are Lockheed Martin jets today, although the F-16 was designed by General Dynamics.

Where the F-35 wins

Stealth decides who shoots first

The F-16 has no stealth. It hangs its missiles, bombs and pods on external stations, and its shape was never designed to hide it from radar.

The F-35A carries its weapons in two internal bays, so a combat load does not spoil its low radar signature. That puts it among the true stealth fighter jets, built to fly into defended airspace and survive.

Stealth costs payload. For missions that do not need it, the F-35A can also load six external wing and fuselage stations, but then it gives up the advantage it was built around.

A cockpit that builds the picture for the pilot

The F-35’s sensors were designed to work as one system. Its Distributed Aperture System gives the pilot a sphere of awareness around the jet for missile and aircraft warning, and the helmet visor shows all the targeting information the pilot needs.

Monessa “Siren” Balzhiser flew the F-16 for 13 years in the Air Force before becoming Lockheed Martin’s chief F-35 production pilot. She told Business Insider that the F-16 had some of that information, but “it was all shown on multiple different displays or formats.”

US F-16s have closed part of the gap. Their APG-83 AESA radar and new electronic warfare suite give them self-defense capabilities that Air & Space Forces Magazine calls “on par with fifth-generation aircraft,” but the jet carrying them is still easy for radar to see.

More than twice the fuel, carried inside

The F-35A holds 18,498 pounds (8,390 kg) of fuel internally, against 7,000 pounds (3,175 kg) for the F-16. The Air Force rates the F-35A at more than 1,350 miles (2,170 km) on internal fuel alone.

Norwegian test pilot Maj. Morten Hanche compared the two in a 2015 blog post, setting Norway’s F-16s against the F-35 simulator. As translated on f-16.net, he wrote that Norway’s F-16s had to refuel several times on Libya missions from Crete, while the F-35 would have flown the whole mission without refueling.

In a similar combat configuration, he added, the F-35 cruises 10,000 to 15,000 feet higher than the F-16 without using afterburner.

Where the F-16 wins

Speed: Mach 2 against Mach 1.6

The F-16 is the faster jet. The Air Force lists it at Mach 2 at altitude, and published specifications give Mach 2.05, about 1,353 mph (2,178 km/h), for a clean jet at 40,000 feet.

The F-35A is listed at Mach 1.6, about 1,200 mph (1,930 km/h). Air & Space Forces Magazine gives that figure with a full internal weapons load, while the F-16’s top speed is for a jet with nothing under its wings.

Siren put it plainly: “The advantage of the F-16 has always been in its speed and turn rate.” Both are slower than the Mach 2.25 F-22 Raptor, which we set against the Viper in our F-22 vs F-16 comparison, and you can see where all three rank in our list of the fastest fighter jets.

Cheaper to fly, by less than you might think

The Pentagon’s fiscal 2026 reimbursement rates, the hourly price charged to other Defense Department users, bill an Air Force F-16C at $14,818 per flight hour. The F-35A is $18,600, about 25 percent more, a far smaller gap than the stealth jet’s reputation suggests.

Buying one is where the difference shows. The F-35A’s average flyaway cost rose to $92 million in production Lots 18 and 19, up from $82.5 million, as we cover in how the F-35A climbed back to $92 million.

The Air Force’s own fact sheet lists the F-16C/D at $18.8 million, but in fiscal 1998 dollars, so the two figures are not directly comparable.

Readiness is the F-35’s weak spot

In fiscal 2024 the F-35A was mission capable 51.5 percent of the time, against an Air Force fleet average of 67.15 percent.

A June 2026 Government Accountability Office report found it has worsened since. Only 38.6 percent of F-35As were mission capable in 2025, and 28.5 percent could perform all their missions, against a goal of 65 percent.

Numbers and a long combat record

A total of 4,604 F-16s have been built, against more than 1,345 F-35s by August 2026. With 2,102 in active service in 2026, the F-16 is the most common fixed-wing aircraft in military service, about 15 percent of all active combat aircraft.

It has also been fighting for more than four decades. Israeli F-16s were credited with 44 air-to-air kills over Lebanon in 1982, with no air-to-air losses of their own.

The newest came in July 2026. Gen. Dan Caine, chairman of the Joint Chiefs of Staff, told a Senate hearing that a Ukrainian F-16 had shot down a Russian fighter; Ukraine said it downed an Su-35S on July 8.

F-16 vs F-35 in a dogfight

Up close, the F-16 has the reputation. Both jets are rated to 9 g, but at half internal fuel the F-16 produces 1.24 pounds of thrust for every pound of weight, against 1.07 for the F-35A.

A 2015 test report made that gap famous. After mock dogfights against an F-16, an F-35 test pilot wrote that “even with the limited F-16 target configuration, the F-35A remained at a distinct energy disadvantage.”

The F-35 program office answered that the test jet, AF-2, lacked the stealth coating, the mission systems software and the helmet software that lets a pilot aim a weapon without pointing the jet at the target.

The F-35, it said, is built to “engage, shoot, and kill its enemy from long distances, not necessarily in visual ‘dogfighting’ situations.”

Pilots who have flown both describe a different trade. Hanche wrote in 2016 that the F-35’s ability to point its nose at high angles of attack “enables me to deliver weapons earlier than I am used to with the F-16.”

He called it an airplane that let him be “more forward and aggressive than I could ever be in an F-16,” while noting its buffeting at high g and a headrest that limits the view behind. Siren said the same high angle-of-attack ability “caught me off guard coming from the F-16.”

Against a heavier opponent the picture shifts again, as our F-15 vs F-35 comparison shows. The F-16’s own matchup with the Eagle is in our F-15 vs F-16 comparison.

Combat record: F-16 vs F-35

The F-35’s first kill of a crewed aircraft came on March 4, 2026, when an Israeli F-35I Adir shot down an Iranian Yak-130 over Tehran. The Israeli Air Force said the engagement was fought beyond visual range with long-range missiles, not in a dogfight.

It lasted a few seconds, Defense News reported, and it was the first time since 1985 that an Israeli fighter had shot down an enemy warplane.

No F-35 has been confirmed shot down, as of September 2026, though one was reportedly hit. On March 19, 2026, a US F-35 made an emergency landing at a US base in the Middle East after a combat mission over Iran, reportedly struck by Iranian fire.

US Central Command said the jet landed safely, the pilot was in stable condition and the incident was under investigation. On July 30, Iran’s Revolutionary Guard claimed to have destroyed three F-35s at Al-Azraq Air Base in Jordan, and Central Command replied that “no US aircraft were destroyed or damaged.”

The F-16 has lost in air combat at least once. In October 1996 a Greek Mirage 2000 shot down a Turkish F-16D over the Aegean; Turkey’s defense minister confirmed it in 2012, while Greece denies it.

The F-35’s closest air-to-air rivals are America’s own F-22 Raptor and China’s J-20, pairings we compare in our F-22 vs F-35 and F-35 vs J-20 comparisons.

F-16 vs F-35 size

The two are closer in size than most people expect. The F-35A is 51 feet (15.7 m) long with a 35-foot (10.7 m) wingspan, against 49 feet 5 inches (15.1 m) and 32 feet 8 inches (10 m) for the F-16.

The F-16 is actually the taller jet, at 16 feet (4.9 m) to the F-35A’s 14 feet (4.4 m). The full side-by-side dimensions are in the database comparison at the top of this page.

Weight is where they part. An empty F-35A weighs about 29,300 pounds (13,300 kg), against 19,700 pounds (8,940 kg) for the F-16.

Fully loaded, the F-35A is in the 70,000-pound (31,750 kg) class, almost double the 37,500 pounds (17,000 kg) the Air Force lists as the F-16’s maximum takeoff weight.

Neither has a second engine to fall back on, a trade-off we cover in our list of single-engine fighter jets.

Is the F-35 replacing the F-16?

Yes, in the US Air Force and across much of Europe, though slowly. The Air Force had 500 F-35As in August 2025, on the way to a planned 1,763, and they are replacing both the F-16 and the A-10, a swap we cover in our F-35 vs A-10 comparison.

The F-16 is not leaving soon. The Air Force had 704 F-16Cs and 134 F-16Ds in fiscal 2024, about 40 percent of its fighter inventory, and is extending 350 airframes beyond 8,000 flight hours, with upgrades planned through 2040 or beyond.

Abroad, Norway, the Netherlands, Denmark and Belgium all chose the F-35 to replace their F-16s, and Israel and Singapore plan to do the same. Romania plans to start retiring its F-16s in 2034 and to fly only F-35s by 2040.

Other air forces still want new F-16s, which Lockheed Martin builds as the Block 70/72. In January 2024 the US approved the sale of 40 of them to Turkey.

The verdict

For a modern air war, take the F-35. It hides from radar, carries more than twice the F-16’s internal fuel, builds the whole picture for its pilot and is designed to shoot first from long range.

The F-16 still wins on speed, numbers and price per hour, and in a close turning fight it keeps the energy advantage the 2015 test exposed. It is also far more widely flown, with 2,102 in service around the world.

The Air Force’s answer is to replace one with the other, slowly. For the Navy’s side of the family, see our F-16 vs F-18 and F-35 vs F/A-18 comparisons, and for the wider field, our ranking of the best fighter jets in the world.
