The Yakovlev Yak-7, also known as UTI-26, was a Soviet military trainer aircraft, developed as a trainer version of the Yak-1. Developed in 1942, a second cockpit was added behind the original one, and the 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. A total of 6,399 were built.
