In Blood Red Skies, a squadron of Yak-1bs is more than a match for any equivalent German fighter squadron. Like other Soviet aircraft, they have high agility and low firepower - so you might struggle to tangle with late-war fighters like the Focke-Wulf 190s, but will fare well against the earlier marks of Bf109.
