I guess he meant Su-27 Flanker B, the NATO code name.
Can I tell you a secret : I hate NATO code names!!!!
When some of my friends ask me "Do you know something about the Foxbat, the Flogger, the Bear, the Hokum,...?" I say "The what? Please speak to me French or better Russian, I don't know anything about these fucking names, I just know МиГ-25, МиГ-23, Ту-95, Ka-50,...".
For me there is only one Су-27.

(Did some Russian pilots give the Cу-27 a nickname?)
