The Yak-7V was developed as a trainer version of the Yak-1. A second cockpit was added aft of the original one, and wing span was increased. It was found that the extra space for the second cockpit could be used for fuel or armament too, and that the performance of the Yak-7 almost equalled that of the Yak-1. Thus the Yak-7 was again developed to a close support fighter. The two-seat version was also used in combat, for reconnaissance missions. 6,399 built. There was also a single prototype with a M-82 radial engine, and an extensively redesigned fuselage to accomodate this. |
