Overview

The F-35A is the conventional-takeoff variant of the largest defense program in history, and the aircraft that defines what a fifth-generation fighter means: very-low-observable shaping, internal weapons carriage, and, above all, sensor fusion. Its AN/APG-81 AESA radar, 360-degree Distributed Aperture System and helmet-mounted display merge into a single tactical picture, which the jet then shares across the force via MADL and Link 16. In practice the F-35 acts as much as a flying sensor-and-command node as a shooter.

More than 1,100 airframes serve with some twenty nations, making it the most-produced stealth aircraft ever and the de facto backbone of Western tactical air power. Unit flyaway cost has fallen to roughly $82 million, below many fourth-generation rivals.

During the 2026 Iran war, US and Israeli F-35s flew the opening nights of the strike campaign, using their low observability to work inside dense air-defense coverage, the type's largest combat employment to date and a heavily scrutinised real-world test of stealth against a layered, modern IADS.

Performance

Speed, range, altitude and engagement capability.

Performance specifications
Max speed

Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.

1,960 km/h
Stronger than 34% of fighters
Max speed (Mach)

Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters.

1.6 Mach
Stronger than 12% of fighters
Range

Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.

2,200 km
Stronger than 23% of fighters
Combat radius

Distance an aircraft can fly, complete its mission and return without refueling. Roughly a third of ferry range.

1,240 km
Stronger than 63% of fighters
Service ceiling

Maximum operating altitude. Higher gives energy advantage and sensor horizon.

15,240 m
Stronger than 31% of fighters
Thrust-to-weight

Engine thrust divided by loaded weight. Above 1.0 the aircraft can accelerate going straight up. On a standalone engine record, this is the engine's own thrust divided by its dry weight, the standard figure of merit for jet engines.

Firepower

Armament, payload and guidance.

Firepower specifications
Main armament

Primary weapon: main gun, cannon or missile type.

25 mm GAU-22/A rotary cannon
Hardpoints

External stations for weapons and pods. More means bigger and more flexible loadouts.

Stronger than 61% of fighters
Weapons payload

Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie.

8,160 kg
Stronger than 76% of fighters

Protection

Armor, countermeasures and survivability.

Protection specifications
Countermeasures

Self-protection: chaff, flares, DIRCM, towed decoys, smoke dischargers, jammers.

Empty weight

Weight without fuel, ammunition or crew.

13,290 kg
Combat weight

Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.

22,470 kg
Crew

Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.
