The two premier fifth-generation fighter jets on the planet squared off over Norway on Wednesday in a mock dogfight that saw U.S. pilots manning the nimble F-22 Raptor and Norwegian pilots behind the stick of the F-35 Joint Strike Fighter. While the F-35 is widely touted as the most advanced aircraft on the planet, the slower and less maneuverable fighter likely had its hands full in a sparring match with the decidedly faster and more agile F-22, though no one from either side has been willing to comment on the victor.

The F-22 Raptor was the world’s first fifth-generation fighter, built from the ground up by Lockheed Martin to serve not only as a multi-role fighter with an emphasis on air superiority but with stealth attributes incorporated into its very design. However, after only around 180 of the fighters were produced, the program was discontinued in favor of diverting funds toward ongoing combat operations in theaters that had little need for air superiority fighters. America’s next fifth-generation fighter, the F-35, was also developed by Lockheed Martin and has earned a number of superlatives within the media and defense community thus far — ranging from “most capable” to “most expensive” airframe ever developed.

Unlike the F-22, which couples stealth with extreme maneuverability to offer an advantage in air to air combat, the F-35 relies on powerful sensors to help it identify and target enemy aircraft well before they’re even aware of the stealthy jet’s presence. The F-35 can then fire over-the-horizon missiles at enemy planes, effectively ending the engagement before the opponent even knows they were there. Effective as this strategy may prove to be for the stealthy F-35, many have nonetheless questioned how well it would fair against a powerful fourth-generation opponent like Russia’s Su-35 if they ever found themselves within visual range.

While offering little in the way of stealth, the Sukhoi Su-35 is capable of maintaining speeds nearly 500 miles per hour faster than those attained by the F-35, it’s also far more agile than the more advanced stealth fighter. Many American experts contend that an F-35 likely wouldn’t bother engaging a Su-35 in a dogfight, and would most likely “bug out” or leave the area in to ensure it maintains its advantage, but questions remain about what might happen if the F-35 ever found itself unable to escape a fight against a quicker opponent.
