Interest in a long-range naval strike fighter gave rise to the Wyvern project, which was to take the Rolls-Royce Eagle-22 engine to cover operations. The project was struck with setbacks, most eventful was the cancellation of the Eagle engine causing considerable time and effort to be lost when searching for another suitable engine that was available. It was decided to utilize a turboprop engine instead and the Armstrong Siddeley Python engine was selected for installation into the Wyvern. The Wyvern with the Python engine was accepted into service in 1953, designated the Wyvern TF 4 initially before renamed into the Wyvern S4. Seeing limited service in the Fleet Air Arm as a carrier aircraft, it was eventually withdrawn in 1958.

Introduced in Update 1.59 "Flaming Arrows", the Wyvern's distinctive marks are its turboprop engine and large ordnance payload. Its exceptional speed capabilities and wide range of available armaments make the Wyvern an excellent choice for combined arms battles. The Wyvern can also be a strong fighter though terrible in high altitudes as engine power drops significantly above 3,000 meters altitude. However, the Wyvern's drawback is its poor maneuverability, so engaging in a dogfight with this aircraft is generally not advised as it would likely end unfavorably for the Wyvern's pilot. Engage in Boom-n-Zoom attacks to make the most of the Wyvern's speed and minimize the maneuverability penalty.
