Combat Yak-1
The combat version of the Yakovlev Yak-1 aircraft is not a separate version and does not bear any special designation. This modification belongs to a large family of the first Jak-1 aircraft, which were produced with various modifications, but without further distinction. It can be said that it was another modification (development stage) of the serial machine Jak-1. Because in this case there were no significant interventions in the design of the aircraft, this modification was not conducted as a new version of this fighter.
