What gives stealth to the F-35 fighter?
The F-35 arsenal is diversified into three essential variants: the F-35A, configured for conventional takeoff and landing; the F-35B, designed for short takeoff and vertical landing (STOVL) operations; and the F-35C, adapted for deployment from aircraft carriers.

The cornerstone of fifth-generation air supremacy, the F-35 Lightning II represents the pinnacle of Lockheed Martin aeronautical engineering.

This aircraft, brother of the F-22 at the forefront of fifth-generation fighters, encapsulates the sum of advances in supersonic speed, stealth capabilities and firepower, the details of which, largely guarded under the cloak of classification, are the result of decades of evolution in stealth technology.

Conceived as a low-profile multirole fighter-bomber, the Lockheed Martin F-35 Lightning II is the latest operational fighter in the United States arsenal, making its maiden flight in December 2006. To date, more than 1,000 units have been distributed between the US Air Force, Navy, Marine Corps, and international allies, including the UK Royal Air Force, with plans to continue production until 2024.

The F-35 arsenal is diversified into three essential variants: the F-35A, configured for conventional takeoff and landing; the F-35B, designed for short takeoff and vertical landing (STOVL) operations; and the F-35C, adapted for deployment from aircraft carriers.

This aircraft is the epitome of a long sequence of innovations in stealth design, whose main task is to evade radar detection. The principle of operation of radar, based on the reflection of waves towards their source, is counteracted in the F-35 through meticulous engineering aimed at reducing this reflection.

F-35 fighter Stealth Technology and Combat Operations

The F-35’s stealth features include flat surfaces and precise angulations to deflect radar waves, thereby minimizing its visibility. The design incorporates sawtooth edges and acute internal angles, with the aim of reducing radar reflection. The F-35’s weapons are housed internally, avoiding external exposure that could increase its detectability.

Material choice is crucial to the F-35’s stealth effectiveness. The aircraft’s skin uses compounds designed to absorb radar waves, such as ferrite and advanced carbon structures, thus decreasing its radar signature.

The engines represent another front in the detectability reduction strategy. Thermal emission from engine exhaust constitutes a significant detection vector, mitigated on the F-35 through advanced cooling systems and bypass nozzles, which minimize the aircraft’s thermal signature.

Despite advances in stealth technology, the F-35 falls short of total invisibility. However, these strategies significantly decrease the probability of detection, its effective range, and the ability of enemy defenses to track and target it, consolidating its position as a strategic asset in the contemporary theater of military operations.
