The Yakovlev Yak-7 (Russian: Яковлев Як-7) was developed from the earlier Yak-1 fighter, initially as a trainer but converted into a fighter. As both a fighter and later reverting to its original training role, the Yak-7 proved to be a capable aircraft and was well liked by air crews. The Yak-7 was simpler, tougher and generally better than the Yak-1. Yak-7B was the standard Yak-7's second improved variant, with a shorter wingspan, upgraded onboard equipment, and is more production-friendly.
