F-16 Fighting Falcon — Fighter / Attack
Open in interactive gallery →See aircraft like this on the live radar →

No combat aircraft has shaped the past half-century of air power as thoroughly as the F-16 Fighting Falcon. Born from a 1972 U.S. Air Force programme seeking an affordable, agile lightweight fighter to complement the heavier F-15 Eagle, the YF-16 first flew in January 1974 and handily defeated the rival Northrop YF-17 in a competitive flyoff. General Dynamics won the full-scale development contract; the production F-16A entered USAF service in January 1979. Today, more than 4,600 examples have been delivered to 25-plus nations, making the Fighting Falcon — universally nicknamed the Viper by its pilots — the most widely operated Western fighter in history.

The airframe's genius lies in its aerodynamic design philosophy: a blended wing-body with a relaxed static stability that a pilot could not fly without fly-by-wire computers, combined with a side-stick controller (the first on a USAF production aircraft) and a reclined ejection seat that allows pilots to sustain 9g manoeuvres. The single Pratt & Whitney F100 or General Electric F110 turbofan pushes the single-seat Block 50/52 to Mach 2.0, and a wide-angle head-up display and HOTAS (Hands on Throttle and Stick) controls were innovations the F-16 introduced to tactical aviation. The internal 20mm M61A2 Vulcan cannon, six underwing hardpoints, and two wingtip stations handle a full range of weapons from AIM-9 Sidewinders and AIM-120 AMRAAMs to Maverick missiles, GPS-guided JDAM bombs, and the AGM-88 HARM anti-radiation missile when equipped with the HARM Targeting System pod.

The Israeli Air Force has written the F-16's most distinguished combat biography. Israeli Falcons destroyed the Iraqi Osirak nuclear reactor in June 1981 — a 1,100 km round trip at the limit of fuel endurance — then racked up 44 confirmed air-to-air kills in Lebanon in 1982 without a single air combat loss. The type scored additional kills during the Gulf War (1991), operations over the former Yugoslavia, and in Pakistani Air Force engagements. Pakistan's F-16s shot down two Soviet-era Afghan Air Force aircraft in 1988. The USAF flew F-16s over Iraq beginning in 1991 and in every subsequent Middle Eastern campaign, and the type has been operated by the USAF Thunderbirds aerobatic team since 1983, its dynamic energy management on full display at every airshow season.

After four decades, the Fighting Falcon line shows no sign of retirement. Lockheed Martin (which absorbed General Dynamics' Fort Worth division in 1993) continues to produce the F-16 Block 70/72 — marketed as the F-16V Viper — equipped with the AN/APG-83 AESA radar, upgraded mission computer, and a digital cockpit. Orders from Bulgaria, Slovakia, Bahrain, and Taiwan extend production deep into the 2020s. At the same time, F-16s in USAF service are being supplemented and gradually replaced by the F-35A Lightning II, though the F-16 is expected to fly with many air forces well into the 2040s. The aircraft's combination of low acquisition cost, well-understood logistics, and continuous upgrade potential has made it a permanent fixture of the global fighter market — the affordable benchmark against which all Western lightweight fighters are measured.

For Kids — a shorter, friendlier version

The F-16 Fighting Falcon is the most-produced fighter jet of the last 50 years. Over 4,600 F-16s have been built since 1976. About 25 countries fly them, making the F-16 the most-common Western fighter in the world. Pilots love it because it's nimble, fast, and easy to fly.

The F-16 is small for a fighter — about 49 feet long, smaller than a school bus and a half. It's also lighter than most fighters. It has one big engine, one pilot, and a beautiful bubble canopy that lets the pilot see in every direction. Inside the cockpit, the pilot sits leaning back at a 30-degree angle, which helps blood stay in the head during sharp turns. The F-16 was the first fighter designed for high-G dogfights.

The F-16 was a breakthrough in fly-by-wire flight controls. Instead of cables and rods, the F-16's stick and rudder pedals send signals to a computer. The computer keeps the airplane stable. Without the computer, the F-16 would be impossible to fly — it's deliberately built unstable for better maneuverability, and only the computer keeps it from spinning out.

F-16s have flown in many conflicts: 1991 Gulf War, 1999 Kosovo, 2001-onward Afghanistan, 2003 Iraq, Israel's wars, and many more. As of 2026, the newest F-16 Block 70/72 has glass cockpits and modern radar. Ukraine received F-16s in 2024 to defend against Russian forces. The F-16 will keep flying for at least another 30 years.

Kids’ Questions

Why is the F-16 built unstable?

Most airplanes are designed stable — they naturally want to fly straight and level, like a paper airplane gliding gently. Stable airplanes are easy to fly but slow to turn. The F-16 is different: it's deliberately built unstable, which means it constantly wants to flip or roll. A computer makes thousands of tiny corrections every second to keep it level. The benefit: when the pilot wants to turn fast, the airplane already wants to turn — it just needs to be allowed to. Unstable + computer = a much more nimble fighter. Without the computer, an F-16 would crash within seconds.

Why did Ukraine get F-16s?

When Russia attacked Ukraine in 2022, Ukraine's air force was small and mostly Soviet-era Su-27s and MiG-29s. After two years of asking, Western countries agreed to send F-16s to Ukraine. The first F-16s arrived in mid-2024 from Denmark, Norway, Netherlands, and Belgium. Ukrainian pilots had to train for about a year first — F-16s are very different from Soviet fighters. Ukrainian F-16s help defend against Russian aircraft and missile attacks. As of 2026, Ukraine has received dozens of F-16s with more coming.

Frequently Asked Questions

Why do F-16 pilots call it the Viper?

The F-16's narrow, pointed nose and the way the cockpit sits immediately behind it reminded early General Dynamics test pilots of a cobra — the aircraft even has a faint cobra head outline when viewed from directly in front. The official USAF name is Fighting Falcon, but the Viper nickname was universal from the flight-test programme onward. By the 1990s Lockheed Martin began using "Viper" in marketing material, and it now appears on factory signage and official brochures.

What is the F-16's top speed and how does it compare to the F-15?

The F-16C Block 50 reaches approximately Mach 2.0 (about 1,320 mph / 2,120 km/h) at altitude. The F-15 Eagle is slightly faster at Mach 2.5+, benefits from two engines, and carries more fuel — giving it a longer unrefuelled radius. The F-16 compensates with a superior thrust-to-weight ratio at lower weights and better instantaneous turn rate, making it more agile in a close-in turning fight.

How many F-16s have been built and are they still in production?

More than 4,600 F-16s had been delivered as of 2024, and production continues at Lockheed Martin's Greenville, South Carolina facility (relocated from Fort Worth in 2019). Current customers taking delivery include Bahrain (Block 70) and Slovakia (Block 70). Taiwan's 66-aircraft Block 70 order is in production for delivery through the mid-2020s, ensuring the line remains open past 2025.

What replaced the F-16 in the USAF?

The F-35A Lightning II is the designated successor, offering fifth-generation stealth, an active electronically-scanned array radar, and integrated sensor fusion. The USAF began retiring older F-16 blocks in the 2020s, but Air National Guard units will continue operating F-16C/Ds for many years. Export customers have no near-term replacement, so the Viper will remain in global service into the 2040s.

Why is the F-16 cockpit tilted back?

The ejection seat is reclined at 30 degrees — far more than the typical 13–15 degrees — specifically to allow pilots to sustain high-g manoeuvres. At 9g, blood is forced away from the brain toward the lower body; the reclined seat reduces the vertical distance blood must travel against g-force, delaying the onset of G-induced loss of consciousness (G-LOC) and letting pilots sustain high-g turns longer without a G-suit alone.

Does the F-16 have a gun?

Yes — a single M61A2 Vulcan 20mm six-barrel rotary cannon is mounted internally in the left wing root, with 511 rounds. It fires at up to 6,000 rounds per minute and is used for close air support strafing runs and as a last-resort air combat weapon. The gun's accuracy benefited greatly from the introduction of the EEGS (Enhanced Envelope Gun Sight) symbology on the HUD in Block 40/42 aircraft.

Has the F-16 ever been shot down in combat?

Yes, though losses are relatively rare given the number of aircraft and combat sorties. Israeli F-16s have sustained the most losses — several aircraft were downed in the 1982 Lebanon War and subsequent operations. The USAF lost at least one F-16C to a Serbian SA-3 missile over Bosnia in 1995 (Captain Scott O'Grady's aircraft). Several coalition F-16s have been lost to ground fire or accidents in Iraq and Afghanistan operations.
