Yakovlev Jak-1

Medium-altitude interceptor Yak-1, originally designated I-26, had a perfect shape, the wooden wings and fuselage of a mixed design. He opened a series of excellent fighters, which was built in large quantities and left their mark in aviation history. Main landing gear retracted into the lower part of the wing towards the fuselage. After rising in the air on January 13 1940., A prototype soon crashed. In the second sample in the design had been some improvement. By the end of the year 64 cars were produced the original series. In the production process made some changes, and, since 1942. Many aircraft have wing main variants with increased scale and throat. Yak-1B use of a new cockpit and reduced rear fuselage, and a variant of the Yak-1M has been less overall weight. In mid-1943. When production ended, was released on 8721 aircraft of all variants.
