Yakolev I-26 / Yak-1


Design of the Yakolev Yak-1 medium-altitude interceptor/fighter began in November 1938, and from it evolved a series of remarkable aircraft (produced in vast numbers) which made an important mark in the history of aviation. Known initially as the I-26, the type had a wooden wing combined with a fuselage of mixed construction and main landing gear units retracting inwards into the underside of the wing. The I-26 looked a thoroughbred and was dubbed 'Beauty' by its design team. Flown initially on 13 January 1940, the first prototype was soon lost in a fatal accident, but the development programme was continued without any break by the second prototype which incorporated some improvements. A pre-production batch of Yak-1s was flying by the end of the year and 64 initial series machines had also been completed by then. By 1941 it had been designated Yak-1. Changes were introduced during the course of production and many aircraft of the main variants were completed from early 1942 with all increased span more pointed wing. A new pilot's canopy and cut-down rear fuselage were introduced on the Yak-1B and reduction of overall weight was achieved with the Yak-1M. The mount of many leading Soviet fighter pilots, Yak-1s equipped a high proportion of fighter squadrons from 1942 onwards, when the type was phased out of production in mid-1943, a total of 8,721 series aircraft of all versions had been completed.
