According to official info, 96 oiae had 40 fighters I-15bis and I-153. On the noon of june, 22, during the fight w romanian bombers over Izmail, the fighters have claim for shot dawn 5 romanian planes (SM-79 or PZL 37). According with the memories of one of mariners from flotilla, two "german" planes were shot dawn straight on the Izmail.
