The Yakovlev Yak-3 (Russian language: як-3) was a World War II Soviet fighter aircraft. Robust and easy to maintain, it was much liked by pilots and ground crew alike. It was one of the smallest and lightest major combat fighters fielded by any combatant during the war, and its high power-to-weight ratio gave it excellent performance. It proved a formidable dogfighter. Marcel Albert, the official top-scoring World War II French ace, who flew the Yak in USSR with the Normandie-Niémen Group, considered it a superior aircraft to the P-51D Mustang and the Supermarine Spitfire. After the war ended, it flew with the Yugoslav and Polish Air Forces.
