Fotogalerij op een Yakovlev Yak-3UA, De Jak-3 (Як-3) était un avion de chasse monoplace soviétique de la Seconde Guerre mondiale. Le Yak-3 avec son faible gabarit et son puissant moteur était doté d’une très grande maniabilité, son armement se composait à la base d’un canon ShVAK 20 mm et d’une mitrailleuse UBS 12,7mm sur le capot moteur. Son développement par Yakovlev débuta en 1941 mais le plus gros de la production se déroula en 1944, de nombreuses variantes de cet avions ont vu le jour suivant des besoins spécifiques rencontrés sur le front (lutte antichar, intercepteur, version en bois, version tout métal etc…). A la fin de la guerre le Yak-3 fut en dotation dans forces aériennes Yougoslaves et Polonaises. Jak-3U: version entièrement métallique et moteur Vk107.

The designation Yak-3UA primarily refers to a series of modern, non-original production aircraft based on the legendary Soviet World War II fighter, the Jakovlev Jak-3.
The Original Yak-3 (Wartime)
- Rol: A highly successful Soviet low-altitude fighter, renowned for its dogfighting capability on the Eastern Front.
- Motor: Powered by the Soviet Klimov VK-105 or later VK-107 V-12 liquid-cooled inline engines.
- Performance: Lightweight and agile, it was so effective at low altitudes that Luftwaffe pilots were reportedly instructed to avoid combat with Yak fighters lacking an oil cooler under the nose (a feature of earlier Yak models).
- Production: Thousands were built during and immediately after World War II.
The Yak-3UA (Modern Reproduction)
The Yak-3UA designation came into use in the post-Soviet era for a new production run catering to the civilian “warbird” market.
- Key Difference: To ensure reliability and ease of maintenance outside of Russia, the original Soviet engines were replaced.
- Engine (Yak-3UA): These reproductions are typically powered by the American Allison V-1710 V-12 liquid-cooled piston engine, which is more readily available and supported globally.
- Constructie: The aircraft were often built using original plans, tooling, and sometimes combined with genuine old stock or heavily refurbished parts.
- Usage: These aircraft are popular in air racing (such as the Reno Air Races) and on the international airshow circuit as high-performance warbirds.
A Note on the Soviet Yak-3U Prototype
A separate, single prototype aircraft existed in the Soviet Union near the end of WWII:
- Designation: Yak-3U (or Yak-3U/ASh-82FN).
- Motor: It was an experimental version that mounted the large, powerful Soviet Shvetsov ASh-82FN radial (air-cooled) engine onto the Yak-3 airframe.
- Fate: While successful in trials, it did not enter mass production due to the end of the war and the priority shift to jet fighters.
The modern Yak-3UA (Allison-powered) is the aircraft most commonly seen and referred to by this designation today.
