The Yak-9, officially Yakovlev Yak 9, is considered by many to be the best Soviet fighter of World War II. It first flew in October of 1942.  It was the first Soviet production fighter capable of besting German fighter aircraft.

Construction of the aircraft involved the use of lighter and stronger materials as the war progressed. Eventually it used mostly aluminum materials for light weight. Engines also increased in power and reliability.

Various models of the Yak-9 included the standard version 9M, a longer range 9D and an extra long range bomber escort designated the 9DD. The ultimate version was the model U, made entirely from metal. It was deployed in July of 1944.

Model U aircraft originally used VK109PF-2 engines that gave them a top speed of about 410 mph. When the engine was upgraded to the VK-107-A in November of 1944, top speed went up to 435 mph.

The Yak-9 was produced through March of 1946. It was used by North Korea at the start of the Korean War.  A total of 16,769 were built.
