The Yakovlev Yak-9 was the Soviet Union’s most successful fighter of World War II. Nowadays, it is relatively little known outside the former USSR. In its day, it was a match for the Luftwaffe’s best fighters, and helped turn the tide of the war. Below are some lesser known facts about the important but little-known Yak-9.

The USSR’s Best Fighter of WWII: The Yakovlev Yak-9
A lightened upgrade of previous Yakovlev fighters, the Yak-9 was initially deployed in October, 1942. It saw combat soon thereafter in the Battle of Stalingrad. Standard armament was a nose-mounted 20 millimeter cannon, plus one or two heavy machine guns. Yak-9s were mostly used to support ground troops by shielding them from German air attacks. They also strafed enemy troops when the opportunity presented itself. Unlike earlier fighters, Soviet pilots considered the Yak-9 to be the equal of the German Messerschmitt Bf 109 and Focke-Wulf Fw 190 fighters. Especially at lower altitudes, where the light Yak-9, although inferior to the Germans in armaments, proved their superior in speed and maneuverability and rate of climb. That allowed the light Soviet airplanes to excel in low level dog fighting.
Yak-9s also proved remarkably durable, able to absorb significant damage and punishment, and still make it back home. They made a difference as soon as they were introduced. Their introduction markedly improved performance over earlier fighters, and helped restore Soviet pilots’ confidence after the catastrophic losses they had suffered in the war’s first year. Such losses had been caused by poor training and tactics, but more importantly, by inferior airplanes that were no match for the modern fighters flown by the Luftwaffe. The restoration of its fighter pilots’ confidence in their equipment finally allowed the Red Air Force to start to claw its way back up and gradually stabilize the situation on the Eastern Front. The Soviet air arm slowly replaced the marked aerial inferiority exhibited against the Germans with aerial parity, then superiority, and by war’s end, supremacy.
The Soviets’ Main Fighter of WWII

After its successful introduction over the skies of Stalingrad, the Yak-9 gradually became the Soviet Union’s main fighter of the war. By 1944, there were more Yak-9s in service than all other Soviet fighters combined. As with other fighters that did particularly well in the war, the Yak-9’s success was due in no small part to the versatility of its basic design. It allowed for steady improvements as the war progressed, and for the utilization of Yak-9s in various roles.
In addition to a defensive fighter, the adaptable Yak-9s were also put to other uses. They were employed as reconnaissance planes, long range bomber escorts, and nighttime fighters. They were armed with 37mm or 45mm cannons, and used as tank busters and general ground attacks. When equipped with bomb loads of up to 1000 pounds, Yak-9s could also serve as light bombers. The Yakovlev Yak-9 was the most produced fighter in the history of the Red Air Force, with over 16,000 rolling out of Soviet factories.
