The Jakowlew Jak-9 ( Russian Яковлев Як-9 ) is a Soviet- made fighter aircraft . It was developed during World War II and manufactured well into the post-war period. The NATO code name of the single - engine low - wing aircraft was Frank .
development
The first flight took place in the summer of 1942 as the successor to the Jakowlew Jak-1 and production variant of the Jakowlew Jak-7DI with a Klimow M-105PF . The troops were introduced in October 1942. 459 machines of this basic version were produced in the GAS-153 and GAS-166 plants. Either the WK-105PF or the WK-105PF 2 was used as the engine. The first use took place in December 1942 at Stalingrad .
In November 1942 a Jak-7 was modified to further increase its performance. It was named Jak-9 / M-106. Improvements related to the cockpit canopy, the now fully retractable tail wheel and the aerodynamics. The M-106 engine , however, turned out to be immature.
During the Second World War, 14 different model variants were produced in large series. The two-seater Jak-9UTI was developed for training purposes, which was equipped with an elongated fuselage, a split cabin and a double control system. In addition to being used for training purposes, the Jak-9UTI was also used for courier flights. In addition, there were a number of experiments. 14,514 copies were built during the war.
In the post-war years, another 2,245 machines were produced, of which 801 were series machines of the post-war version Jak-9P, which were delivered from January 1948 to December 1948. They were used in Albania, China, Hungary, Yugoslavia, North Korea and Poland, among others.
commitment
The Jak-9 was the most widely used fighter by the Soviet Air Force during World War II. It was used as an escort, interceptor and long-range fighter, fighter-bomber and attack aircraft for fighting tanks. Their use contributed to the air superiority over the German air force . During the Korean War , a Yak-9 of the North Korean armed forces shot down a B-29 for the first time on July 12, 1950 over Seoul .
